Some SQL questions.
Hello friends,I have a few questions.
1. what sql statement returns the name and the maximum size of the data file in the database?
2. how to find the location of the trace files database using the data dictionary?
3. which database view and column shows the number of validations has done a user session?
4. How do you change the oracle default database block size, without recreating the database?
5 What is poorly stated or right, so bad... that is wrong with this query.
SELECT column1 from tableABC including NOT IN (select Column1 from tableXYZ);
6. What is the most effective way to write this statement?
7. How do you determine that the new application is more effective than the original query?
Hello
+ 1. What sql statement returns the name and the maximum size of the data file in the database? +
SELECT file_name, bytes
FROM dba_data_files
WHERE IN (SELECT MAX (bytes) bytes
FROM dba_data_files)
+ 2. How to find the location of the trace files database using the data dictionary? +
With the help of the parameter $ v
For example, select name, value of the parameter $ v
WHERE name like ('% dest');
3. which database view and column shows the number of validations has done a user session?
+ 4. How to change the size of the oracle default database block, without re-creating the database? +
Database block size is not editable once database created, however depending on your version, do you use
block of different size avaiable in oracle version db_4k_cache_szie, db_8K_cache_size (not if your default block size is 8K), db_16k_cache_size
+ 6. What is the most effective way to write this statement? +
7. How do you determine that the new application is more effective than the original query?
EXPLAIN_PLAN running on query and analysis cost timing. Simply also check how long it took the request to return the result;), the formula gross to discover the effective application

Hi all I have a basic sql question
Watch below two querries
I think as operator will not compare with all the values, but not the outcome it will compare with all values... When comparing with the value null, the result is automatically null1. select 1 from dual where 1 in (select 1 from dual union all select null from dual) It gives output as 1 but below one 2. select 1 from dual where 1 not in (select 2 from dual union all select null from dual) It gives output as no data found
I'm wrong
Please help me on this
and why performance wise in operator is more better than no of?
Thanks to all in advanceThanks for posting your explain plan command

Some General Questions about the externalization of authentication
We plane to outsource the APEX authentication so that it would be linked to the credentials of the end-user network. Were do because:
It is more in line with the expectations of the users.
It will simplify maintenance by the user.
When the user leaves the ice, their APEX access will be automatically disbanded as their network connections are disabled.
We found some very good articles on the subject, for example http://www.greenit.li/greenIT/Willkommen_files/Oracle_APEX_ProofOfConceptNTLMPLSQL.pdf (other suggestions would be welcomed and encouraged). However; We have a few questions:
The first is authentication and authorization. We get how end users can be authenticated based on Active Directory. However, within the APEX now, create us a new user and specify if who are developers, who, team development Application Builder, SQL workshop, they can access. schemas are accessible to them, etc. This page requires, of course, a password.
How will this work if the authentication is outsourced? We always create the same user in the APEX?
If so, what should we put the password related areas?
If this is not the case, how do we control authorization once authentication completed successfully?
If not, how to make the application available for users (authenticated network) and not others?
If the application allows the user to pass a password (assuming that they are properly connected to the network), what should happen when a person clicks on logout?
Thank you for any input,

One of the elements of game here (great requirements above) is to make sure that the APEX applications are directly linked in the cycle of creation/decommissioning of the user of the organization. In other words, the desire is that deleting or disabling a user account in the central directory (Active Directory) have the effect of disabling access to all enterprise systems. We do not expect to allow some "heavy" end users the ability to access the SQL browser. Is there something that can be done, perhaps with the authorisation schemes, which would allow their access is automatically revoked if it network id have been revoked? Can authorisation schemes be applied to the APEX development pages maybe?
Laughing out loud
The only thing that comes to mind is running a scheduled task on your databases which retrieves users APEX in the APEX_WORKSPACE_APEX_USERS view, checks the user account is still valid in AD using dbms_ldap (assuming that the user IDS match, or there is a convention to get from one to the other) and removes , expires or to block those who are not using the APEX API. The problem which is the

restriction to the user of apex_util API. Comply with the scheduled job will have to Re: create a session programmatically (that is to say, outside the APEX)., who is skating on or above the line about the API without papers/not taken in charge. This may be frowned upon by the great above and Oracle. (However, in this case it is less of a concern that the use of such methods in your APEX applications, which certainly, I would not recommend.)

Hi all
Below are some of the question related to the dashboard and reporting.1. how we handle guests specific user scope
Guests of scope are not specific to the user, but incase you need to do this then you will need to create the edge/separate pages for the users/grps table that is long and tedious process (AVOID)
2. dynamically manipulate the components to show or hide
By using the conditional Section guided Navigation for 10g and action links in 11g
3. don't OBIEE manages several items with no impact on performance
What you mean here... 2 independent things, I'd say. There are several ways to improve performance once the needs of the business are met.
4. how to display the detail records in a dashboard where the user wants to scroll up and down
Dashboard report folders can be managed using the report properties
5. is it possible to right SQL custom in a page?
Can use request Direct to database to point to a valid connection pool and write SQLs
6 dealing with guests cascading
Achievable
7. transfer value to a dashboard to a different dashboard
Are there different methods to achieve this
8 from graphs conditional formatting
Achievable based on conditions
9. is it possible to pass the value from one page to another page in the dashboard
Are there different methods to achieve this
10. how to manage the large number of legend items in the single chart
With the help of the legend view
11. a dashboard get corrupted if all changes made in to ask level
What do you mean here? Dashboard is just a layout where various queries and reports are integrated. CAB always change you it.
12. dynamically change the title or header in graphics
Not possible at the level of graphical property but workarnds are there to satisfy operational requirements.

What kind of pl sql questions can you expect for a customer technical interview
Please notify all experienced professionals
What kind of questions can I expect in the customer facing interview technical I have to a PL SQL Developer with interview of performance tuning. The customer is primarily a financial project.
Yes of course I would essentially tell me about the projects that you been involved in based on who they ask the questions, basically I'm not very experienced 3 years and my experience involves performance limited tuning, to develop scripts to support front-end web applications.
What kind of questions (you do not need to enumerate the issues specifically, it would be useful that you could advise the areas where I should look into, all the links where I can read about the region suggest you also face a customer interview).
Example: Financial transaction processes much as treatment so I have to prepare for any question on the changing Table, blocking.
Also, I am aware of the Collections, external Tables. These would be discussed.
Any advice would be very helpful.
My experience does not imply strongly any financial experience and job specification does not state so I got through the 2 first interview series. It would be a disadvantage if I said that I have had no experience of finanicial, I guess just by hearing from some sources that the customer is finance.
I would be hired only if the customer agrees, so I need to deepen as much as possible, it's time to prepare for good trying to inform.
Kind regards.Rider wrote:

Personally, when I interview candidates PL/SQL, the least important thing for me is real business knowledge. I want to rather a competent PL/SQL Developer who knows his stuff, a person having poor skills of PL/SQL and a good knowledge of the company.
We will pay that person for PL/SQL capabilities - and not knowledge of business (that of why we have analysts and managers of project and team leaders). Remember that the code ' + financial + "is no different code" + detail + "-the same language is used. The same concepts. The same methods to solve problems. As the problems you are dealing with a level of PL/SQL are technical - where business issues have already been processed by analysts and architects at a higher level.
I expect, however, that such a developer will resume business over time knowledge. But I don't see it as any kind of precondition.

Some basic questions on TestStand
Hello
I'm new on the test stand and I just finished my first sequence. I have some questions on how to do better.
My sequence steps about 100 it is running. One of the steps that happen quite frequently is a break so that the previous output VI can take effect. Right now I use a VI with one that takes an integer as an input and makes a break during this time. Is there a more elegant way to do it?
VI another I use saves some data and runs all the 6 step or so. The only difference between each execution is a setting of path for the filling of journal to be issued. I wish that the sequence to be as clean and well placed as possible. Is there a clever way to short-circuit the number of steps down?
Basically, it seems that you have basically 3 things that could potentially happen: travel, Journal, break sensor.
So why not create a data type for every thing. For example, your MoveSensor data type would be a container that looks like this:
MoveSensor
Boolean SensorFlag
Digital NewPosition
Digital CurrentPosition
etc...
Your Log data type would look like this:
Boolean LogFlag
String FilePath
Digital time
etc...
Your break would be just a number (PauseTime)
Then, you bring a container with each type of data into it. And then do a table of these containers.
Now by using the ForEach flow control step type, you can iterate through the table. The pseudo code would look like this:
ForEach item in my table
If CurrentElement.MoveSensor.SensorFlag is true
MoveSensor to CurrentElement.MoveSensor.NewPosition
CurrentElement.MoveSensor.CurrentPosition is equal to the new position
If LogFlag is true
Log LogPath (maybe the loop on that for a certain period of time)
Wait (CurrentElement.PauseTime) set to 0 if you do not need to take a break
End ForEach
This way you would add just the elements in the table. You can also write the array a property object (read about those in the help) file and the test, just read in a different property object file that would fill your table with different values in function.
Hope this helps some,

Some General Questions of CVI - how does the compiler
Hello
I work with CVI 9.1 for more then a year during this time i ' v noticed a couple things, I would like to help me to understand.
- Work with several C files:
- When I'm writing a software that uses lets say C files and files of 10 H 10: Main.c Main.h File1.c File1.h Panels.h Panels.uir and so on... I'm implementation of the function in the c file and its deceleration of writing in the file h, i ' v noticed that sometimes I get msgs of the compiler on the conflicts, maybe there's a way I know not just for the CVI?
- Works correctly with the file UIR for example lets take the files written above, if I have sign - HAND and control led1 and I want to do SetCtrlVal in the Main.c I can implement as this SetCtelVal(MAIN,MAIN_LED1,1); but when I go to file1.c and try to do it, I get the error message that main_led1 is not a control value (I included the Panels.h) this problem happens to me a lot is there a solution? or maybe I am doing something wrong...
- What is the best way to implement bollean var (true false) for the software? is it possible to add this var always?
- decelerations of incompatible type: allows you to take the Fmt function for example when I'm trying to use it in another file, I get the decelerations of incompatible type with the names of the files...
- General question: lets say I want to include
in my project and I want to use its features in main.c and file1.c, I included in two files? or there is a way to include it in a single file only?
2. to access the buttons
- lets say that I have buttons and I am pressing on it after pressing the button I have a loop for 10 min, I want to create a button give up, but I can't press anything because the keys are "locked out" is there a way besides multi threading to implement this?
Wow! A very broad set of issues!
A quick response.
- Works correctly with the file UIR for example lets take the files written above, if I have sign - HAND and control led1 and I want to do SetCtrlVal in the Main.c I can implement as this SetCtelVal(MAIN,MAIN_LED1,1); but when I go to file1.c and try to do it, I get the error message that main_led1 is not a control value (I included the Panels.h) this problem happens to me a lot is there a solution? or maybe I am doing something wrong...
There is a basic error in your statement: the first (SetCtrlVal) parameter must be the handle Panel, which is the reference to the object in memory that is created when you call LoadPanel (). Using the name of constant sign is not correct: it may work if you're lucky and you have the Panel handle with the same value as the name of the constant, but this certainly isn't the correct way to address on a panel controls.
Even if I don't understand the error that you declare: I expect 'the control is not of the type expected by the function' or an error of inconsistent data type (like passing an int to double check) or...
Remember that each function that processes objects on a Panel must be aware of the handful of Panel, then either you pass to the function as a parameter, or store it in a global variable.
- decelerations of incompatible type: allows you to take the Fmt function for example when I'm trying to use it in another file, I get the decelerations of incompatible type with the names of the files...
I normally leave CVI #including the necessary system files: when I use certain functions like Fmt in a source file and compile ICB warns me to add the relevant include file, and it does it correctly. Operating in this way I never had problems with formatting and the I/o library functions. You can rebuild the inclusion list by removing all #includes in yous source files and compilation of the project, this should correct errors
- General question: lets say I want to include
in my project and I want to use its features in main.c and file1.c, I included in two files? or there is a way to include it in a single file only?
You must include the file containing the definitions of the functions in all source files that use. Or you can create a general include file with all included in your project and include only this one in all of your source files
- lets say that I have buttons and I am pressing on it after pressing the button I have a loop for 10 min, I want to create a button give up, but I can't press anything because the keys are "locked out" is there a way besides multi threading to implement this?
It is a general rule that animates the CVI environment: during the execution of a loop inside a function (a reminder of command or another function) the system does not handle the user interface events, so that your buttons appear locked. This can be solved by adding a call repeated (ProcessSystemEvents) inside the loop: this way of all UI events are monitored and managed by the system.
You must use this method with caution: before entering the loop, you must disable all the controls that can be used during operation (normally only the Quit button should stay active) otherwise, you can enter a situation in which other callbacks are executed during the loop that might interfere with it.
In such a case, do not put a reminder in the stop button and the use of a global variable I have normally create a toggle button Stop and manipulate it in this way:
While (1) {}
....
ProcessStemsEvents ();
GetCtrlVal (panelHandle, PANEL_STOP, &stop);)
If {(stop)
... gracefully out of the function
break;
}
}
This argument has been discussed several times in the forums: do a search for ProcessSystemEvents returns a large number of discussions you can read
- What is the best way to implement bollean var (true false) for the software? is it possible to add this var always?
CVI is not a native boolean value. I used to use an int and test weather it is zero or not
- When I'm writing a software that uses lets say C files and files of 10 H 10: Main.c Main.h File1.c File1.h Panels.h Panels.uir and so on... I'm implementation of the function in the c file and its deceleration of writing in the file h, i ' v noticed that sometimes I get msgs of the compiler on the conflicts, maybe there's a way I know not just for the CVI?
I do not understand what you describe: could you add some piece of code allowing to penetrate this situation and report exactly the message the compiler warns?

Two questions: Running XP and have some interesting questions at the start and with IE.
Hi, I try to wear the IT hat and works to clear up some questions on my mother's computer. #1 I guess that the computer was shipped with a version of Corel Photo software on it and we cannot get rid "Installer" messages at the beginning upward. We tried to remove the program and the same message comes back to tell us that "Installer can do the requested action without the CD/program files" it gets about 6 of these reviews that it must close any until the computer will continue to boot the system. Please, please tell me how to get rid of this. I tried to install the 'Installer' update to see if that would make the difference and nope. I also tried to remove the Corel file via CCleaner and got the same message. I do not have the program disc, I don't want to program... I want to just get rid of it!
#2 when entering address in the Internet Explorer address bar, the browser opens a second browser instead of going to the requested site. For example, when I open my Internet Explorer and say go to the top of the address bar and typewww.google.com, instead of going to Google, it opens a completely separate browser. When she did this, it's EXTREMELY SLOW! until you think that IE went unresponsive and then finally opens the second browser.
I'd appreciate any help! I'm trying to solve these problems, while I'll be staying here so that I can leave him a computer running.
Thank you!

BlackBerry Smartphones has BB for less than 24 hours... some (stupid) questions!
Hi all
I looked through some tips and read the summary instructions (at best) that came with my BB and now have a few questions, if that's ok:
1. I downloaded the "favorite" of Facebook, but I don't know where that is? I thought this would be an icon, I could then add to the home screen? If it IS, then how can I find and to do this?
2. is it possible to add my iTunes Catalog, or a part of it, to my BB - are compatible somehow?
3. how to choose something other than the horrible Vodafone home page, to be my homepage on the internet?
5. What is the difference between "browser" icon and the icon "WAP"? Am I meant to go through one preference to another, because in the end, they both make the same thing?
6 represents the number of pins only to give BB 'friends', so we can chat on messenger, or there are homonyms?
Again, sorry for the stupid question; I'm really proud of the implementation so far without any help from the husband, but having my llimitations, lol - it's a world apart form the Nokias I've owned exclusively for the past 13 years... but I think I love her!
Thank you

1. I don't know about a 'bookmark', unless you try to bookmark a place in your web browser? You can download and install the Facebook for BlackBerry application.
Use the browser of your BlackBerry to access www.blackberry.com/facebook
2. Yes, use of BlackBerry MediaSync software...
http://NA.BlackBerry.com/eng/services/media/mediasync.jsp
iTunes with DRM will not transfer, DRM coding should be removed first of all files.
3. open the browser to the page that you are going to choose as your home page, and then press the Menu key > Options > browser Configuration > scroll down > address Home Page > use current Page

I am a newbie to SQL and I studied the book of Fundamentals SQL Server Oracle OCA 12 c, but a section on natural joins to confuse me.
Basically, the author says:
SELECT r.region_name, d.department_name, l.city, c.country_name
DEPARTMENTS d
NATURAL JOIN places l, c countries, regions r;
The natural join between DEPARTMENTS and LOCATIONS creates a provisional result, consisting of 27 lines since they are implicitly attached on the column of location_id. This set is then Cartesian-joined to the table of the COUNTRY as a join condition is not implicitly or explicitly specified. 27 interim lines are attached to 25 lines in the COUNTRY table, which gives a new temp results set with 675 (27 × 25) rows and three columns: DEPARTMENT_NAME, CITY and COUNTRY_NAME. This set is then attached to the REGION table. Once more, a Cartesian join occurs because column REGION_ID is absent from any join condition. The final result set contains rows and four columns (675 × 4) 2700.
I can understand because you evaluate joins from the left. But then he wrote:
The JOIN... USE and JOIN... ON the syntaxes are better suited to join multiple tables. The following query joins four tables using the natural join syntax:
SELECT country_id region_id, c.country_name, l.city, d.department_name
DEPARTMENTS d
NATURAL JOIN places l
NATURAL JOIN country c
NATURAL JOIN region r;
This query generates correctly 27 lines in the final results set since the required join columns are listed in the SELECT clause. The following query illustrates how the JOIN... CLAUSE is used to extract the same 27 lines. A join condition can reference columns only in its scope. In the following example, the join of DEPARTMENTS slots can not reference columns in the COUNTRIES or REGIONS of tables, but the join between the COUNTRIES and REGIONS may refer to any column of four tables involved in the query.
This second method of the part of the natural writing joined confuses me. I don't understand the logic behind the 2nd series of States of Natural Join. For me, it seems that the first series and the 2nd set look alike, but they are apparently not.
Can someone tell me the differences?
Thank you!!
Hello
The more important thing to learn more about NATURAL JOIN is: never use it. If you add new columns, joins can get different results. I've never heard of someone uisng NATURAL JOIN apart from a manual or a question like yours.
There are a lot of things in Oracle that take the time to learn and are useful. All the time you spend learning things is better spent on them.

Try structured: ask some Conversion Questions
So, finally I will give FM structured a serious whirlpool. My style FM use unstructured is consistent and predictable.
I'm trying to use the online resources, including, http://help.adobe.com/en_US/FrameMaker/12.0/Help/Using/index.html, , I saw samples of Adobe to file > new > Document > explore structured models, but, honestly, they are light. Also, I looked at the Adobe TV video on converting unstructured structured. . However, Miss me some information.
I'm working on my first conversion table:
(1) should what element name conventions I follow? I use Easter breaks now, but don't account using all lowercase so he preferred. Should what names I use? 'P' for the body of the text or "Para", for example?
(2) I understand to map the heading styles to the elements that I call 'Head', and different styles of body to the elements, I will name 'Para'. My bullets and numbered lists that I match the items that I give the word, 'Élément' and I plan to create a wrapper of the 'list' for these, for example. Agenda is defined with a 'Type' attribute which can be "numbered" or "chips". I know there are other ways to approach that, like using explicit UL and OL elements or envelopes.
(3) what should I do with the paragraphs I have graphics anchor to? I have an AnchorGraphics tag for anchoring of the images and an AnchorTable tag for the anchor tables. If these become 'Para '? Should and can I maps a tag FrameMaker to anything, so he goes?
(4) what I'd do with remarks, precautions and warnings? Are these also best as elements of "Para", or if they get their own?
You have thoughts and resources?
Thank you!
Sean,
I think you can ask questions without solid answers. There is probably a significant variety of opinions out there, all of which are just that... opinions. The short answer is that you need to understand what works for you, and maybe it's not what works for someone else.
There are some who would you like to forget this exercise together and just use existing data, such as DITA or Docbook structure. It's certainly an option. I use not or because it doesn't work for me.
So, let me tell you what works for me, with regard to the questions you have asked. This is all subjective in your case, but it is based on a very busy and highly refined workflow, producing good results for many years.
1. name element conventions - I love tiny element names that DITA uses, such as
(((, - , etc. because 1) they are short and easy to visualize 2) I know not what they mean because I am a writer and they are also similar to HTML in some cases 3) short the tag of the element, the least amount of overhead in the file structured and also XML, if you export in XML format.
2 - as long as author, I find much faster specify a
- explicit or something in
- , rather than defining an attribute. In addition, it is much easier to see in the view of the structure. In addition, there is less overhead in the source file. DITA called a header element
... I like this better than<Head>, but once again, it is just me.<p class="reply"> <p class="reply">3. for the numbers, I use a <fig>item that matches my tag "AnchorGraphics". The <fig>element has two children...<image>and<title>. The<image>element is a graphic element that inserts a framework anchored in the empty AnchorGraphics paragraph (created by <fig>). Then, the container<title>element inserts a new paragraph for the legend of the figure. The end result is the same as the use of unstructured FM standard, except that the management of the space reserved AnchorGraphics is much better automated and controlled. IOW, you don't have to worry about this more... the element structure does this for you. Among the myriad of benefits of the structure.<p class="reply"> <p class="reply">4 - DITA defines a single <note>element that has an attribute to control if it appears as a note, attention, etc. I like this approach. You can reuse the <para>element, but my thinking is that this would really complicate your background formatting rules. Explicit <note>element seems much better.</note> </para> </note>
5 - tables - Yes to your basic question, although there are a lot of different names, you can choose the elements. To follow the model of DITA or CLIENT access licenses, you must also an ancestor more in the tree that is the parent of the real table element. DITA, it is the
SQL * PLUS connects with SQL > question
People,
I'm confused on the command. / sqlplus with Oracle database.
According to my understanding,. / sqlplus connected with SQL > using option 3: sysdba, sysoper, sysasm.
I connect with SQL > to run the rel853.sql script to create a table PSOPRDEFN but a field "OPERPSWDSALT" did not appear in the table PSOPRDEFN although it is in the Create Table statement.
I connect with SQL * in the directory/home/user/OracleDB_Home/bin as below:
$ export SYSTEM_PASS = AccessId/mypass
$ export ORACLE_HOME = / home/user/OracleDB_Home
$ export ORACLE_SID = HRCS90
$. / lsnrctl start LISTENER
$. / AccessId/mypass sqlplus as sysdba
SQL > startup
SQL > @/opt/PT8.53/scripts/rel853.sql
SQL > select OPERPSWDSALT in the AccessId.PSOPRDEFN;
It returns: "OPERPSWDSALT": invalid identifier.
I checked the table PSOPRDEFN that the OPERPSWDSALT field did not appear in the table PSOPRDEFN.
I tried the sysoper option as below:
$. / sqlplus AccessId/mypass as sysoper
SQL > startup
SQL > @/opt/PT8.53/scripts/rel853.sql
SQL > select OPERPSWDSALT in the AccessId.PSOPRDEFN;
It returns: "OPERPSWDSALT": invalid identifier.
The sysoper error is the same thing with sysdba error.
I tried the sysasm option as below:
$. / sqlplus AccessId/mypass as sysasm
He returned: connection refused.
Someone told me this connection as SYS causes this error. If not a sysdba, sysoper, or sysasm, use the command. / sqlplus AccessId/mypass cannot connect with SQL >.
My question is:
First of all, why is what OPERPSWDSALT did not appear in the PSOPRDEFN table while it is in the CREATE TABLE statement?
Seocond, if not use SYS which is one of the 3 options, how to run the command. / sqlplus AccessId/mypass to connect with SQL > so that CREATE TABLE PSOPRDEFN correctly?
Thank you.

Hello. Thanks much for the reply. I just do the commands below:

$. / lsnrctl start LISTENER

Its release: the USER is "SYS".

Its output:

As we see above, unable to connect to the Oracle database AccessId.
My question is:
What to do on AccessId, so that it can connect to the Oracle database?
Thank you.
so much for the use that you refuse to actually use COPY it PASTE & so that we can see the whole session.
In the past, you did
> SQL > startup
Maybe the database is out of order & must be started.
do exactly as below (line by line)
ID
sqlplus
/ as sysdba
startup
connect AccessId/mypass
COPY the results from above then PASTE all back here
DATA_TYPE Oracle (using SQL) questions
I have a Client Server application that I created using a server for MS - SQL (MS - SQL Server 2008 R2 Express) database.Since MS - SQL Server has wide range and number of DATA_TYPEs, I chose to devote some of these DATA_TYPEs to the application-specific processing (mainly MONEY and DATA_TYPES BOOLEAN).
In addition, I decided that in the Client Application that the general treatment of a particular field would be determined by the corresponding DATA_TYPE stored in the database.
The value of the DATA_TYPE for a particular field within the SQL Server database and can be determined by querying:
"select DATA_TYPE from INFORMATION_SCHEMA. Columns
"where ((Column_name = «my_Field») and (Table_Name = 'myTable')).
I also extract/use other DATA_TYPE information as necessary or appropriate.
With this information the Client Application can systematically treated differently may be a MONEY (a DATA_TYPE in MS - SQL Server) a decimal or one BIGINT (two other DATA_TYPEs in MS - SQL Server). I have to create the field with the correct DATA_TYPE in the database, but after that I don't have to worry about this.
.
.
.
Now, I'm moving a database to Oracle (Oracle Database Express Edition 11 g Release 2). And I would have the same (or similar) feature, as described above.
Oracle has less DATA_TYPES is more difficult to bind an application-specific-data type to a database-Oracle-DATA_TYPE-specific. There are simply not as many "sacrifice" to my specific processing of the application. I don't want to treat each field DIGITAL like 'le-apps-money-type.'
With Oracle can I associate 'the-apps-money-type', let's say, a NUMERIC (9,2), then the Client Application will process all NUMERIC (9.2) as 'the-apps-money-type '.
The Client Application queries the Oracle database for DATA_TYPE DATA_PRECISION, DATA_SCALE to make this determination.
But this approach doesn't appeal to me, suppose I have other NUMERIC fields (9,2) who are not of the 'the-apps-money-type '. How can I set and then later determine, from the Oracle backend, if the NUMERIC field (9.2) is intended to be used as 'the-apps-money-type' or just a regular number?
Is it possible I can create a kind of "sub DATA_TYPE" in Oracle?
I have considered this in the COMMENT field associated with particular field. Then a query for this comment when I did DIGITAL DATA_TYPEs. But the COMMENTS field seems not to turn all_tab_columns and user_tab_columns.
(With Oracle SQL Developer, you can create/edit/delete user created tables/fields. COMMENTS can be added to the individual fields in a table - this are the COMMENTS that I am referring above).
.
.
.
What I would do, and a more direct approach for me, would be in some way create a user defined DATA_TYPE is simply:
(1) a user defined DATA_TYPE name (such as MY_MONEY_TYPE),
(2) associated with a built-in Oracle data type (such as NUMERIC (9.2).)
Then when the client application queries user_tab_columns the field may be treated appropriately. If I can't do it, maybe there is somewhere else I may be put and subsequently ask for such information.
What are the most direct ways to implement the functionality described above?
You can create an object type and certainly use it in your table definition
SQL> create type my_money_type as object (
2 val number(9,2)
3 );
4 /
Type created.
SQL> create table foo (
2 col1 number primary key,
3 col2 my_money_type
4 );
Table created.
SQL> insert into foo values( 1, my_money_type(1.23) );
1 row created.
SQL> select col1, col2 from foo;
COL1
-------
COL2(VAL)
--------------------------------------------------------------------------------
1.00
MY_MONEY_TYPE(1.23)
This usually isn't a particularly good way to design an application, however. Types of objects are very useful in the treatment of PL/SQL, but their conservation in a table is usually a pain - you must constantly to call the constructor of the object and the getter methods (I did not worth defining here) assuming that you want to return the number of 1.23 rather than an instance of MY_MONEY_TYPE.
