• Function returning the tree used with the object type

  Hi guys!
  
  I'm fighting for some time now of a function that should return the tree structure of the employees. Let me clarify...
  I have a table say Manager and employees (two columns for an example)
  MANAGER_ID
  EMPLOYEE_ID
  
  Example:
  
  MAN_ID - 1; EMPLOYE_ID - 2;
  MAN_ID - 2; EMPLOYE_ID - 3;
  MAN_ID - 2; EMPLOYE_ID - 4;
  MAN_ID - 4; EMPLOYE_ID - 5
  
  The purpose of my function is back for a specified MAN_ID everyone in the tree...
  
  Example:
  
  RETURN_TREE (1) return {2,3,4,5};
  RETURN_TREE (2) returns {3,4,5};
  RETURN_TREE (4) returns {5};
  
  How to get there?
  
  With respect,
  
  PsmakR

  And use BULK COLLECT or the COLLECT function to build the collection:

  create type emp_table as table of number(6);
  /
  

  DECLARE
   v_emp_list emp_table;
  BEGIN
   select cast(collect(employee_id) as emp_table)
   into v_emp_list
   from employees
   connect by prior employee_id = manager_id
   start with manager_id = :p_man_id
  
   -- or
   /*
   select employee_id
   bulk collect into v_emp_list
   from employees
   connect by prior employee_id = manager_id
   start with manager_id = :p_man_id
   */
  END;

• 'Function SQL Query return' using with Flash graphics

  I created a pl/sql function that returns a SQL query in a varchar2 of this form:
  
  Select the null link
  -value > < x value
  < value y of Series1 > series 1 label
  < value Series2 y > 2 series label
  < value of y Series3 > series 3 Label
  ...
  ...
  from tablea a
  Join tableb b
  On a.col = b.col
  order of < x value >
  
  If I call the function of a graphic Flash box series SQL with the Type of Source query "SQL query" value that returns the function like this:
  
  return functionname (to_date ('30-sep-2010, ' mon-dd-yyyy ""))
  
  It parses correctly and the page is saved; However, when I run the page I get no output - error messages or another indication of a problem.
  
  Now, if I call the function in a SQL client, capture the result of the query SQL using the dbms_output and paste that into the box graphic Flash series SQL - change the Source Type of SQL query query - and save the page it works fine when I run it and returns a chart series flash.
  
  Can anyone suggest either;
  
  1. what I might have missed or done wrong?
  2. a way to effectively diagnose the problem...
  
  I tried to use the debugger Apex - what is very nice, indeed - but it provides no information on what might be my problem. I tried to write my own my function debug messages using the apex_debug_message package - nothing...
  
  Thank you

  Hi Eric,.

  Try to pull the source like this:

  begin
     return functionname(to_date('30-sep-2010', 'dd-mon-yyyy'));
  end;
  

  This works very well for me, and if I take the begin-end and the final semicolon from the return statement I get the same behavior as you.

  He doesn't mention in aid of the source (only during the wizard if) this source type must be expressed in this way, but I agree, it would be useful that the tool would validate to this format meets it "Query SQL that returns the function" or give some sort of indication of the sentence. In any case, this should help you will again.

  Hope this helps,
  John

• I need to create a curved with type text box that heal and return to the next line in the form of curved text. How do I do that?

  I need to create a curved with type text box that heal and return to the next line in the form of curved text. How do I do that?

  1. Draw a set of concentric half circles also spaced, stacked so that the outermost is the most remote.
  2. Use the text tool to add text to the outermost path, thus creating a PathType object.
  3. Select all the paths. Type > threaded text > create.
  4. Text tool: click at the end of the text in the object of PathType. Continue typing.

  

  > If I do that it will not type more.

  A Warp effect is a direct effect. When it is applied to the type of objects, they are still editable text. The chain will deform, however, the text also, not only the paths to which it is attached. Sometimes you want that, sometimes you don't have.

• Choose a view with nested object types

  I use 11.2 DB. I created 2 types of objects. The contact_t has been integrated into the student_t object and I created a view with the nested object.

  How do you choose the values of the object contact_t type in the view SQL? I want to see the values of the contact_t object in speerate areas (ie. contact_name, city, Department...)

  Thank you

  CREATE or REPLACE TYPE contact_t () AS OBJECT

  DCID NUMBER (10),

  Contact_Name VARCHAR2 (50).

  City VARCHAR2 (50).

  State VARCHAR2 (10),

  zip VARCHAR2 (10),

  e-mail VARCHAR2 (100))

  CREATE or REPLACE TYPE students_t () AS OBJECT

  DCID NUMBER (10),

  ID NUMBER (10),

  last_name VARCHAR2 (50).

  first name VARCHAR2 (50).

  middle_name VARCHAR2 (50).

  contact contact_t)

  
  

  VIEW to CREATE or REPLACE students_t students_view

  WITH the OBJECT IDENTIFIER (dcid) AS

  Select decided,

  ID,

  last_name,

  first name,

  middle_name,

  contact_t (dcid, contact_name, city, state, zip, email)

  FROM MyTable

  What exactly is the problem? Are you an error? An ORA-01730 by chance?

  Use the default STUDENTS_T constructor in the query from the view:

  VIEW to CREATE or REPLACE students_t students_view

  WITH the OBJECT IDENTIFIER (dcid) AS

  Select (students_t)

  DECIDED

  id

  last_name

  first name

  middle_name

  , contact_t (dcid, contact_name, city, state, zip, email)

  )

  FROM MyTable;

  Then, for example:

  SQL > select t.id

  2, t.contact.contact_name

  3, t.contact.city

  4 t students_view;

  ID CONTACT. CONTACT CONTACT_NAME. CITY

• When I burn CD for my use on the computer, sometimes the order of the songs are returned, starting with the last song first.

  * Original title: Windows Media player

  When I burn CD for my use on the computer, sometimes the order of the songs are returned, starting with the last song first.  This is the CD, or I do something wrong?  This isn't an ongoing problem... most of the time it's ok.  Can I change the order manually. If Yes, where and how.

  Thank you

  Lee

  Lee - there are a number of possibilities. First of all, it depends whether you burn audio disks or data - if they are audio discs, you can check and rearrange the order of songs in the burn list - if necessary - before you start burning. If you drag multiple files to the burn list quite often the last track you clicked on will go upward, so I wonder if it is what can happen. Back with a little more detail if I not quite correctly interpreted the problem. Best regards, Ric.

• Windows XP Home edition has crashed - how to return WXP and use with the product key?

  Hello. I bought an Equium L20 last year and after 1 year my windows crashed due to a virus. I want to know how to get a real windows xp OS because the product under my laptop key is always saved for me and is a legitimate product but I can't get windows because it was obviously preinstalled and no CD was given to me with the package.

  How can I get back Windows to use with my product key on my WIN sticker below my laptop.

  Hello

  First of all, it is very strange that recovery CD is not delivered with your laptop. It's hard to believe, but anything is possible. As you know after buying a new product, it is very important to check all orders sent with it and if something is missing, you must call the local as soon as possible and not to wait a year.

  Sorry but this key code belongs to original recovery image and you can't use it with every installation of Windows XP Home edition CD. In your case, there are two options:
  -You can buy the CD of facilities Microsoft original WXP (with the key correctly code) or
  -Contact the partner of service allowed in your country and order the new CD from recovery for your laptop model.

  All that s!

  Bye and good luck!

• Tables created in a stored procedure cannot be used with dynamic SQL? The impact?

  There is a thread on the forum which explains how to create tables within a stored procedure (How to create a table in a stored procedure , however, it does create a table as such, but not how to use it (insert, select, update, etc.) the table in the stored procedure.) Looking around and in the light of the tests, it seems that you need to use dynamic SQL statements to execute ddl in a stored procedure in Oracle DB. In addition, it also seems that you cannot use dynamic SQL statements for reuse (insert, select, update, etc.) the table that was created in the stored procedure? Is this really the case?
  
  If this is the case, I am afraid that if tables cannot be 'created and used"in a stored procedure using the dynamic SQL, as is the case with most of the servers of DB dynamic SQL is not a part of the implementation plan and, therefore, is quite expensive (slow). This is the case with Oracle, and if yes what is the performance impact? (Apparently, with Informix, yield loss is about 3 - 4 times, MS SQL - 4 - 5 times and so on).
  
  In summary, tables created within a stored procedure cannot be 'used' with dynamic SQL, and if so, what is the impact of performance as such?
  
  Thank you and best regards,
  Amedeo.

  Hi, Frank.

  Thank you for your response. I understand that the dynamic SQL is required in this context.

  Unfortunately, I am yet to discover "that seeks to" using temporary tables inside stored procedures. I'm helping a migration from MySQL to Oracle DB, and this was one of the dilemmas encountered. I'll post what is the attempt, when more.

  In Oracle, we use [global temporary Tables | http://www.psoug.org/reference/OLD/gtt.html?PHPSESSID=67b3adaeaf970906c5e037b23ed380c2] aka TWG these tables need only be created once everything like a normal table, but they act differently when they are used. The data inserted in TWG will be visible at the session that inserted data, allowing you to use the table for their own temporary needs while not collide with them of all sessions. The data of the TWG will be automatically deleted (if not deleted programmatically) when a) a commit is issued or b) the session ends according to the parameter that is used during the creation of the TWG. There is no real need in Oracle to create tables dynamically in code.

  I noticed that many people say that the "Creation of the tables within a stored procedure" is not a good idea, but nobody seems necessarily explain why? Think you could elaborate a little bit? Would be appreciated.

  The main reason is that when you come to compile PL/SQL code on the database, all explicit references to tables in the code must correspond to an existing table, otherwise a djab error will occur. This is necessary so that Oracle can validate the columns that are referenced, the data types of those columns etc.. These compilation controls are an important element to ensure that the compiled code is as error free as possible (there is no accounting for the logic of programmers though ;)).

  If you start to create tables dynamically in your PL/SQL code, so any time you want to reference this table you must ensure that you write your SQL queries dynamically too. Once you start doing this, then Oracle will not be able to validate your SQL syntax, check the types of data or SQL logic. This makes your code more difficult to write and harder to debug, because inevitably it contains errors. It also means that for example if you want to write a simple query to get that one out in a variable value (which would take a single line of SQL with static tables), you end up writing a dynamic slider all for her. Very heavy and very messy. You also get the situation in which, if you create tables dynamically in the code, you are also likely to drop tables dynamically in code. If it is a fixed table name, then in an environment multi-user, you get in a mess well when different user sessions are trying to determine if the table exists already or is the last one to use so they can drop etc. What headache! If you create tables with table names, then variable Dynamics not only make you a lot end up creating (and falling) of objects on the database, which can cause an overload on the update of the data dictionary, but how can ensure you that you clean the tables, if your code has an exception any. Indeed, you'll find yourself with redundant tables lying around on your database, may contain sensitive data that should be removed.

  With the TWG, you have none of these issues.

  Also, what is the impact on the performance of the dynamic SQL statements in Oracle? I read some contrasting opinions, some indicating that it is not a lot of difference between static SQL and SQL dynamic in more recent versions of Oracle DB (Re: why dynamic sql is slower than static sql is this true?)

  When the query runs on the database, there will be no difference in performance because it is just a request for enforcement in the SQL engine. Performance problems may occur if your dynamic query is not binding variable in the query correctly (because this would cause difficult analysis of the query rather than sweet), and also the extra time, to dynamically write the query running.

  Another risk of dynamic query is SQL injection which may result in a security risk on the database.

  Good programming will have little need for the tables of dynamically created dynamically or SQL.

• HP Operating System CD sold and used with the computer of the other company.

  I bought this CD from:

  AClass products

  32 c Westfield, Trading Estate

  Westfield Trading Estate

  Midsomer Norton, Somerset

  BA3 - 4BH

  United Kingdom

  I found on this CD - he wrote "For Distribution only with new" or HP Compaq PC

  Commercial sale claim, is that you can use it on any Acer, Dell, Fujitsu, Toshiba and other computer laptop or desktop - if they are, things can go wrong.

  Its great to buy a HP CD to go with the HP for laptop or desktop, even if they think that using it on other computer companies may not cause problems. If I used it on a Dell, Toshiba or another computer, I know he can or can not install, but if this is the case, it may hang after that I have try or warn just not. That is why, I know things happen. For example you get HP Logo to appear in a Dell computer, or the Dell Logo appears in an HP computer - if the computer can still run the software, the software of the BIOS has instructions Stop and Go, just like WIFI and brand cards labeled software.

  My problem or the question is, if someone claims its possible to use the CD of the HP operating system on other computers from computer companies, as if the problems never happen, its apples mixture similar to oranges unless you like a fruit salad, its best to put things in their place. I would like to know the truth of HP or an expert, some people say its strange I would have problems, they think it's harmless - there must be a reason for the problem when it is used on different computers. It would be good to know that I'm not the only one who knows how this happened, to confirm what I discovered and read, or if asked that its harmless to use with other computers, or simply absurd, and why.

  Hi Kabigan

  I even asked Microsoft and the answer they gave me, it's illegal. Society, I bought an OEM CD (Got back CD instead) and license, even to send the label with the serial number where his tell clear the Furijitsu, my old laptop computer is Hp. normally in my area where I worked as HE consultantant license belong to the preinstalled computer, it was purchased with.

  My experience it won't work, because a recovery cd is check the bios and see that this isn't the computer that made the recovery cd. I have not yet opened the package, because I consider return the cd and the company label.

  I may be wrong because I don't know the law, but normally software license is the same for the EMEA region for the whole country. It could be if she sold the Germany law differs "German Federal Court of Justice 06/07/2000 (find ZR 244/97) distribution of OEM and DSP licensing."

• Any camera regardless of the interface is available for use with the LabView interface.

  The question is

  1. is a camera regardless of the interface is available for use with the LabView interface?
  2. Can I build a VI to communicate with any device image and recording of camera and take the data?

  Any kind of help or advice is greatly appreciated... I have to buy a CMOS camera and begin to run.

  Thank you...

  Hello Virginia,.

  I am pleased that this information has been useful, one thing I wanted to mention is that USB 3.0 has its own standard USB 3.0 Vision which is currently not supported. If this camera is also Direct Show compatible then you will be able to acquire an image using IMAQdx and manipulate all the attributes that are published to the API Live Show.

  I hope that USB 3.0 Vision will be supported in the near future, and we tentatively announced for this standard of communication for the August 2013 Vision Acquisition Softwareupdate.

  See you soon,.
