Benefits of using a table or a view in Oracle
Hi friends,I have a question about the difference between tables and views.
Greetings

Yes... but then, someone is bound to point out that views can be materialized in persistent data objects. +

using plsql table and ref cursor in oracle's 10 g
Hi all
Can someone give me an example of a scenario where we need to create a form manually based on a stored database procedure.
And in this process, I created a pl/sql table and a Ref cursor at the database level.
CREATE OR REPLACE PACKAGE SCOTT. TYPE BONUS_PKG IS bonus_rec
IS (RECORD
EmpNo bonus_EMP.empno%TYPE,
Ename bonus_EMP.ename%TYPE,
employment bonus_EMP.job%TYPE,
SAL bonus_EMP.sal%TYPE,
Comm bonus_EMP.comm%TYPE);
TYPE b_cursor IS REF CURSOR RETURN bonus_rec;
TYPE bontab IS TABLE OF bonus_rec INDEX DIRECTORY.
PROCEDURE bonus_refcur (bonus_data IN OUT b_cursor);
PROCEDURE bonus_query (bonus_data IN OUT bontab);
END bonus_pkg;
CREATE OR REPLACE PACKAGE BODY SCOTT. BONUS_PKG IS
PROCEDURE bonus_query (bonus_data IN OUT bontab) IS
II NUMBER;
CURSOR bonselect IS
SELECT empno, ename, job, sal, comm bonus_EMP ORDER BY empno;
BEGIN
OPEN bonselect.
II: = 1;
LOOP
Look FOR bonselect IN
.EmpNo bonus_data (ii),
.ename bonus_data (ii),
.job bonus_data (ii),
.Sal bonus_data (ii),
.comm bonus_data (ii);
EXIT WHEN bonselect % NOTFOUND;
II: = ii + 1;
END LOOP;
END bonus_query;
PROCEDURE bonus_refcur (bonus_data IN OUT b_cursor) IS
BEGIN
Bonus_data OPEN to SELECT empno, ename, job, sal, comm bonus_EMP ORDER BY empno;
END bonus_refcur;
END bonus_pkg;
I want to fill in the data in the forms manually is not using Forms data block Wizard and by program.
Please answer...Can someone give me an example of a scenario where we need to create a form manually based on a stored database procedure.
In general, you will use a block of proceedings based when you have a collection of data from several tables presented in a form and your username must be able to update the information displayed.
In your sample code, looks like you are using Oracle Support document "Melting a block on a Stored Procedure - examples of Code [ID 66887.1]". If this is the case, continue to follow the document - it guides you through all the steps. There is no need to manually configure things that the data block Wizard will work for you!
I want to fill in the data in the forms manually is not using Forms data block Wizard and by program.
Why? Let the wizard block configuration data of your block based on a procedure for you. There is no need to manually browse the data! I did what you're trying, and it's more work needed. Leave forms to do the work for you. :)
If you absolutely have to do things manually, I recommend that you use the PROCEDURE bonus_query (bonus_data IN OUT bontab) instead of bonus_refcur (bonus_data IN OUT b_cursor) . Then, in your code create a variable of type BONTAB, and then call the bonus_query procedure. Then, it's a simple case of a loop in the table of records returned by the bonus_query procedure. For example:
DECLARE t_bonus bonus_pkb.bontab; BEGIN bonus_pkg.bonus_query(t_bonus); FOR i in 1 .. t_bonus.count LOOP :YOUR_BLOCK.EMPLOYEE_NUMBER := t_bonus(i).empno; :YOUR_BLOCK.EMPLOYEE_NAME := t_bonus(i).ename; :YOUR_BLOCK.EMPLOYEE_JOB := t_bonus(i).job; :YOUR_BLOCK.EMPLOYEE_SALARY := t_bonus(i).sal; :YOUR_BLOCK.EMPLOYEE_COMMISSION := t_bonus(i).comm; END LOOP; END;This code example shows the basics, but as is the sample code - you will need to adapt to your situation.
Also, I highly recommend that you look at the article inol listed. It is a very thorough debate on the REF CURSOR. If you have set up using a procedure based on the data source - it is more effective to spend the record table to your form that it must pass a ref cursor Using a ref cursor, you might as well just using a standard called cursor and loops on your named cursor. The effect is the same (a line returned at the same time creating lots of network traffic). Using the table of records is more efficient because the data set is returned if the network traffic is reduced.
Hope this helps,

Chanchal,
If you can read my original post carefully you may have noticed that all these restrictions will not apply in my case.
All,
In any case I found the solution to my problem.
There are a few additional restrictions for materialized views multilayer
Additional Restrictions for master materialized views
The following types of materialized views may not be masters of editable materialized views:

Add FK between a table and a view?
Is this possible in 4.1 to add a FK between a table and a view (off of course)?
If I'm in a view, it seems that I can define a FK to another view or a table, but if I start with a table, some views appear in the list. The view already has a defined PK.
Is it normal?
Use case: I have a table of generic code, so I'm set up views on the code for each type of code table. Then, I want at least diagram CF from specific code view of the code typed column on a table for the sub.
Hello Kent,
Is this possible in 4.1 to add a FK between a table and a view (off of course)?
Yes. You can do this by clicking on the icon of the new foreign key above the diagram, then by selecting the view first, then the table.
I connected an enhancement request to allow a foreign key to a view to be added using the table properties dialog box.
Thanks for pointing it.

Problem with the af:table links and views
I want to display a table with data from a database table called PERSON, so I use af:table tag.
The PERSON table has the following fields:
- PERSON_CODE
- PERSON_NAME
- PERSON_COD_STATE
The PERSON_STATE field is a foreign key to another table called PERSON_STATE:
- PERSON_COD_STATE
- DESCRIPTION
I created a view for the data of the PERSON (personView) table. Because I want to show the person status description in the af: table, I created another view for the data in table PERSON_STATE (personStateView). And I've also created a link between personView and personStateView.
In the column of the af: table that represents the State of no one, I drop the field 'description' of the State view linked to the view of anyone.
When I run the JSP, the State is not displayed correctly. All persons are displayed with the same State.
During the test directly with the application module, the display link works correctly.
View links inside an af:table work?
I work with ADF 10 g.
Thank you
Your scenario should be treated with a sql (VO on two EOs) join with a relationship master / detail. The table will be able to browse the details for each master record to time stamping.

I know that it is not possible to use a variable in a view, but I wonder if it isn't a work around? If there is a single value - from another table - you want to reuse in a view that doesn't use dynamic SQL code, how do you then? I've been playing around with statements, but makes me anywhere, I use 11r2.
BTW, please don't ask me the standard litany of questions in anger-dba (why do this? your database is f *, RTFM, etc.), it's just for my own curiosity. :)
Thank you
Example for demo only for purposes (I know that is not syntactically correct):
var_value variable varchar2 (30)
Start
Select this_is_just_one_value
int: var_value
from tableX where column1 = "BOB";
end;
Select
numerous_columns
of tableY

Why are you doing this? your database is f *! RTFM! Etc! ;-)
SQL is not a procedural language - you can't create a view for example that has a parameter signature. For example, it is possible in a language of the proceedings:
declare cursor c( deptID number ) is select * from emp where deptno = deptID; begin open c( 1234 ); --// open SQL cursor using a parameter/variable --// etc.. close c; end;It is not possible using a SQL object as a point of view. As a vision is not a procedure. If the same approach than what the above using SQL (stupid example, but only shows the basic principles):
// define create or replace view emp_view as select * from emp; // use select * from emp_view where deptno = 1234;The CBO is smart - and he's probably going to push such a predicate in the SQL emp_view statement.
To set up this view, is ugly. And should only be taken into account in dealing with issues such as data security restrictions. A context is created - this may contain a number of name values. The view can then use a name-value of the context. Oracle data dictionary views using this approach.

Update of a Base Table in a view with a UNPIVOT function.
Hello
I have a requirement to upgrade a Base Table in a view.
This view has the query by using a function of the UNPIVOT operator to display the columns in the tables of the basic of the lines.
I need to update/insert in / remove the Base Table by accessing the view (the user has access to the Base Table, so the DML on the view).
Here is the table I created:-
The sample values are inserted in this table using the script below: -.CREATE TABLE PERSON_DETAILS ( PID VARCHAR2(10 BYTE), FIRSTNAME VARCHAR2(1000 BYTE), LASTNAME VARCHAR2(1000 BYTE), PHONENUMBER VARCHAR2(1000 BYTE), ADDRESS1 VARCHAR2(1000 BYTE), ADDRESS2 VARCHAR2(1000 BYTE), COUNTRY_CODE VARCHAR2(1000 BYTE), LANGUAGE_CODE VARCHAR2(1000 BYTE), EMAIL VARCHAR2(1000 BYTE) )
The code for the display is as below: -.insert into person_details values ('1','XYZ','ABC','1234567890','India','Asia','IN','EN','[email protected]'); insert into person_details values ('2','XYZ2','ABC2','1234567890','India','Asia','IN','EN','[email protected]');
Here are the values of the view:-CREATE OR REPLACE FORCE VIEW PERSON_DETAILS_VIEW ( PID, CD_NAME, CD_VALUE ) AS SELECT "PID", "CD_NAME", "CD_VALUE" FROM person_details UNPIVOT INCLUDE NULLS (cd_value FOR cd_name IN (firstname AS 'First Name', lastname AS 'Last Name', phonenumber AS 'Phonenumber', address1 AS 'address1', address2 AS 'address2', country_code AS 'Country Code', language_code AS 'Language Code', email AS 'Email') );
The user would fire any statement as below: -.PID CD_NAME CD_VALUE 1 First Name XYZ 1 Last Name ABC 1 Phonenumber 1234567890 1 address1 India 1 address2 Asia 1 Country Code IN 1 Language Code EN 1 Email [email protected] 2 First Name XYZ2 2 Last Name ABC2 2 Phonenumber 1234567890 2 address1 India 2 address2 Asia 2 Country Code IN 2 Language Code EN 2 Email [email protected]
The statement above should update the PERSON_DETAILS database table.update person_details_view set cd_value = 'US' where CD_NAME = 'IN'
I understand that I can write an INSTEAD OF trigger, but I don't know what logic to write in the trigger so that the condition is met.

Can I build an application using a table that is owned by another user?
Greetings,
I am very beginner in Oracle, and I really need help with this point.
I created 2 user accounts: user1 and user2.
In User1, I wrote:
GRANT CONNECT, RESOURCE
for User2.
Grant select, insert, update
on table1
for User2.
Now, user2 can see the content of this table, but only in the part SQL (select * from user1.table1)
How can I create an application that uses the table1 to user2?
When I go to application builder, I have to choose one of the tables belonging to the user2. But I can't use table1 User1 although that User2 has permission to access.
Any help?
Thank you in advance!
Beginner's daughterHello
There is a powerful solution, that you can use.
You can create a view. Some views may be editable (this means that it is possible to update
the Table for the view) and you can add some constraints (Primay Key) on a view.For example:
CREATE or REPLACE ADVICE {color: Red} User2.view_name {color}
(col1 {color: red} {color}, col2 {color: red} {color})
UNIQUE RELY DISABLE NOVALIDATE,
The CONSTRAINT {color: red} pk_view {color}
Col1 PRIMARY KEY {color: red} {color}) MATTER DISABLE NOVALIDATE
) AS
SELECT col1 {color: red} {color}, col2 {color: red} {color} OF {color: Red} User1.Table1 {color};This example is from the link below:
[http://www.psoug.org/reference/views.html]
Hope this can help.

Create a trigger instead of update several tables in a view
Dear everybody
I am trying to create a trigger that updates instead of to day joined several tables in a view, but I can't get my trigger to work. The create view command was as follows:
The view above connects a polygon table to the table of function names which means that a polygon appears several times in a view, even though one version of the polygon exists in the base table. This means the direct update of view cannot take place, since 1 polygon can appear multiple times in a view. The two original base tables and their columns names are:CREATE OR REPLACE VIEW VIEW_MI_JOIN_GC AS SELECT MAP_INDEX.mi_prinx, index_type_id, original_map_publication_id, original_map_sheet_number_id, name_of_feature, geog_coordinates_id, GEOG_COORDINATES.mi_prinx AS "mi_prinx_polygon", GEOG_COORDINATES.geographical_coordinates, GEOG_COORDINATES.mapinfo_style_row FROM MAP_INDEX JOIN GEOG_COORDINATES ON geog_coordinates_id=GEOG_COORDINATES.mi_prinx;
Relax, I created was as follows:MAP_INDEX --------- MI_PRINX INDEX_TYPE_ID ORIGINAL_MAP_PUBLICATION_ID ORIGINAL_MAP_SHEET_NUMBER_ID NAME_OF_FEATURE MAPINFO_STYLE_ROW GEOGRAPHICAL_COORDINATES GEOG_COORDINATES_ID GEOG_COORDINATES ---------------- MI_PRINX GEOGRAPHICAL_COORDINATES MAPINFO_STYLE_ROW
The idea is that when I draw a new polygon in MapInfo and assign him a revised number geog_coordinates_id and the number of mi_prinx_polygon, which are the same, once I have save the view as then it updates the underlying tables. Geographical_coordinates and mapinfo_style_row of map_index table columns are columns with ancient polygon data which while not having currently new data inserted into them, are required for the previous data they contain. These data are currently being added to the geog_coordinates table with other scripts. The idea is that all the data is then read using a view and updates made to the view, triggering instead of relaxing, so data are not duplicated but still visible as if it were.CREATE OR REPLACE TRIGGER TRIG_VIEW_MI_JOIN_GC INSTEAD OF UPDATE ON VIEW_MI_JOIN_GC REFERENCING NEW AS NEW FOR EACH ROW BEGIN UPDATE MAP_INDEX SET mi_prinx = :NEW.mi_prinx, index_type_id = :NEW.index_type_id, original_map_publication_id = :NEW.original_map_publication_id, original_map_sheet_number_id = :NEW.original_map_sheet_number_id, name_of_feature = :NEW.name_of_feature, mapinfo_style_row = :NEW.mapinfo_style_row, geographical_coordinates = :NEW.geographical_coordinates, geog_coordinates_id = :NEW.geog_coordinates_id WHERE geog_coordinates_id = :OLD.geog_coordinates_id; UPDATE GEOG_COORDINATES SET mi_prinx = :NEW.mi_prinx, geographical_coordinates = :NEW.geographical_coordinates, mapinfo_style_row = :NEW.mapinfo_style_row WHERE mi_prinx = :OLD.mi_prinx; END; /
When I created first the relaxation above in SQLdeveloper it seems to run constantly. Then my computer crashed, not related to this work, and I lost session because I did not commit it. I was not ready to commit it because I believe that something is wrong.
I am in the trigger syntax correctly and I go about it in the right way? I want to only update the rows that have changed, that's why I was using: NEWS and: OLD.
Kind regards

95 / 5 / 1 use rule for more Desktop Viewer
Hello
Russ Proudman written this in a workstation of discoverer recently:
«To many clients and presentations, I highly recommend the ' 95 ol / 5 / 1 rule is that you have 95 users using the Viewer, 5 users using more and maybe 1 with office (and most likely, it is the 1 with Admin as well).»
I wonder, is the standard for most places? If so, why this rule?
My last job, we used the 5/95/1 rule, where only a few used Viewer, almost all the most used and administrators used Desktop. Why? Is a superior to the Viewer tool. Search options and options (up to 10.1.2.2) input parameter sheet display options are superior to what is shown in the Viewer (more other reasons are not here). Only users who have accessed Viewer worked on remote sites - usually their homes - where the most access was terribly slow.
Curiously, in my current workplace, we follow your rule. I prefer the 95/5/1 rule. We plan to go to the 5/95/1 rule to 10.1.2.2 due to problems with the binding of one sheet to another by using the managed links. If we do not have, we must abandon our upgrade altogether. Oracle does not provide a solution for us at this time.
Just curious.
Thank you
NancyI can explain my thinking better with the following:
1. Firstly, Disco Viewer takes less band bandwidth and memory to run more. You can search the forums for amounts - that I don't remember - but as more are XML and Viewer is HTML the difference of the info, packages, etc., beyond the intranet at work is a factor. And then, as mentioned, less memory required to use the version of the Viewer.
2. here is my soapbox reason:
So many customers, I am the 'right' thing for management to say is that "our users are entitled" which means that they want their users to write their own reports, etc.. Even if an intermediate layer to make things easier is installed (ie: NoetixViews, BIS views), end users - even trained - do not use the product every day and so create literally hundreds of programs that are poorly written, shared with their friends and run queries "dumb" don't don't need (ie: have a field index, but by causing ignorance research be a full array of research). They are usually no standard and the results are often incorrect (ie: trying to cross the orgs in Oracle Apps?, using Multicurrency in Oracle Apps or regular DB tables?, etc..).
So when it is time to level or a new IT manager comes along and tries to put an end to the prevalence of reports such as 'Margin Report - Budgets (do not use after Jan.2.2001 GL', ' margin Report - GL Budgets (it's good, but run only Monday) ", etc., it becomes an important task.
I found over so many times that if a company has a few report writers - and of course, depends on the company, but something like 5 would be a good thing - who know SQL, who know Disco and have been trained, and use the product on a daily basis - then only they should use more to create the reports and the other 94 / 95 / 100 would only her pre-existing companies reports made by these 5 and with the right combination of settings, etc., a report of the observer should allow multiple ways to view the data (ie: GL date per account, between a dollar amount, etc.).
And that leaves just the 1 or so to be the Admin and the same person who needs office.
3. that being said, I've also found that many companies treat just identical to something like Oracle Apps discoverer. If Oracle Apps is slow - they set with several hardware configurations, etc. and to pay for a team of consultants to do. If the discoverer is slow because the server was set up wrong, they run another large application in the Disco box or users write "obstinate" reports... then the answer is usually "discoverer sucks... try [A]"-when [A] seems to be the flavour of the day - that is to say: don't insert the following: motion of Brio, Business Objects, Cognos Impromptu , Hyperion (good Oracle Hyperion now)... and the new fav... OBIEE.
So having a good administrator of Disco, some well trained, competent report writers and lotsa' end user runs these reports pre-written... it's where everything works.
4. one last thing - I realize that a company can roll Disco more to all users and maintain the "power" of end-users down so that they can only operate pre-written reports as described above. It's okay as Yes, more is more user friendly and looks like 'cooler' in my opinion. But then, it's just the problem of network and memory to watch out for. I stayed in most of the companies does not present (only 1 so far), but it's a reasonable enough request. The problem was that they should start with just a spectator and see that the end users are simply glad to get the data. If they give them first, then nobody wants to feel "decommissioned" Spectator later.
Hope that explains my opinion better. Although it may seem a bit "negative, it is sure that I seem to find time and time again.

Cancel button type on a table or a view form
I am a newbie to apex. I use 10g. I created the form on table emp (empno, name, salary). Shape is of type Form on a Table or a view.
Cancellation & save button (apply the changes) do not work. then I copied the page reset process and run on condition save button click. But always Cancel button does not work. application has other forms of type Form with a report and are working properly. I lost 2 days on this problem.Hello
You can do it. If you have the junction in the same form, what to use empty the cache of the page. Click on the edit page, click Cancel in the left button section. Scroll to the bottom and type page 32 in the field to clear the cache . However, it is better to have the direction to report page (different page of the form).Hope this will help.

Hello world
We use a table control to display the log files. Each row of the table represents a log file entry. In addition to that we have put in place
Some filter chopsticks (string tonalite) to speed up filtering. This means that only the entries corresponding to these substrings are shown. So whenever the filter options
changed to renew the contents of the table.
This is done by DeleteTableRows, looking for entries to display, InsertTableRows and SetTableCellRangeVals.
It works very well.
But if we remove all the contents of the table (caused by the filter options) and then hit a button (even if the focus is on the table) you get a GPF on ProcessSystemEvents.
This occurs only after inserting a large number of rows in the table before deleting all the. For example, a table with 5000 x 2 (rowsxcolumns) reduced to 0x2.
1 create a table with 5000 x 2 (rows x columns) control elements.
2 remove all lines
3. press tab until the control panel to get the focus.
4. hit Enter for example
=> Crash
Someone has an idea? We have already 'dimmed' CTRL, but this is not enough to avoid that the focus on the table by pressing the tab key. So, which leads to an accident as well.
Thanks for the help
Philipp
Yes, it is a known issue (396240), although it is not actually on time last updated known issues. Unfortunately there is no good solution, other than just by waiting for a version corrected to be released, which should happen soon.

Can you attribute programmatically size when you use the table in the Cluster service cluster
I use the table of the Cluster service. The only way I know to the size of the cluster is to right click on the function and set the Cluster size. But what happens if the length of my table changes? Is there a way to make the cluster size is the number of elements in the table? Seems like labview should do this automatically at run time. There may be some nodes of property I don't know.
I tried the SQL statements, but it always boils down to having to know the number of columns is in the database prior to execution.
What I did to generate the object to be a cluster to match database fields. My recordset is an array of objects. Then I a vi member to build a recordset from the database and another Member vi to retrieve an array of clusters of the recordset object. If the database changes, I have to change the subject and these two vi. All the other Subvi call these two for the manipulation of data. No other sub - VI have bundle and ungroup functions in them, only the vi of two members. Thus a change in the database requires a change of control and two vi. Not too bad.
(I'm tooting my Horn in choosing me as accetped solution provider. I learned this bad habit of others here on the forum.
)
