  Oracle stored functions cannot return result sets directly but can return the REF CURSOR. Please read [optimize result set retrieval using ODP.NET and Ref Cursor | http://www.oracle.com/technology/pub/articles/mastering_dotnet_oracle/williams_refcursors.html] which gives complete examples in PL/SQL for the side Server and VB.

  Hi Gary,.

  You must RETURN the result of the function:

  BEGIN
   RETURN validate_stuff(:P3_DOC_SEQ);
  END;

• How can I access a journal or a report that lists the results of an operation of Disk Defragmenter?

  How can I access a journal or a report that lists the results of an operation of Disk Defragmenter?

  Windows Defrag is supposed to run silently in the background.

  Hello

  You can use the builtin: SRW. GET_REPORT_NAME
  This function returns the file name of the running report

• PLSQL function to return the result of the query

  Dear all,

  Oracle Database SE1 11.2.0.1

  I need to create a plsql function which should accept SQL as a parameter, execute it and return the result set.

  Is this possible?

  Be careful - results games indicate a set of data stored in memory. This is not what are sliders. This isn't how Oracle should be used.

  Imagine that you implement such a result set function - which, on average, requires 1 MB of memory (private server) to store the results of the SQL query. A 100 users mean a 100 MB of memory required server. This is not suitable. Not at all. Never.

  The correct back 'thing' is a handle to SQL cursor (called a ref cursor in this case). A SQL cursor is a "program" - that the appellant runs via the fetch command and generates one or more lines accordingly. Appellant repeatedly runs this slider through calls to fetch until this slider found and returns all rows affected (using consistent readings).

  If you want an abstraction interface that the client can call via PL/SQL code in the database, so this crafting optimal SQL interface, creates the SQL cursor and returns the handle of the cursor (via the ref cursor data type) to the client.

• Why CVI have functions that duplicate the functions of ANSI C file handling (ex: Openfile)?

  Why CVI have of file manipulation functions that seem to reproduce the functionality of the ANSI C functions?

  Is there an advantage to using the CVI functions?

  As the CVI was released (1987), until the ANSI-C standard is released (1989) maybe the question should be the other way around!

  In those early days, CVI was supposed to be cross-platform, so it was logical to develop a set of libraries that operate in the same way across the different computers it was targeted at. These days, the focus seems to be primarily under Windows, so this philosophy at the beginning is a bit redundant, especially, as you say, with the widespread adoption of ANSI-C.

  Personally, if there are similar functions in CVI, and ANSI, I'll go for the ANSI, whenever for portability of the reasons, but yet I write code in a number of different programming environments.

• a function that returns the type with a table joint!

  Good day to all,
  I have a function that returns a type.
  
  so I select it as:
  Select * from table (function (param1, param2))
  
  now I want to combine this with a table so that the settings for the service we get from the join table. Is this possible? And how?
  I tried different options without success.
  
  something like:
  Select *.
  table table (function (b.column1, b.columnb) x), tablea b
  where x.a = b.col
  
  Is this possible?
  
  Thanks in advance?

  What return NULL validation function is passed. If it returns a character string, then the validation failed and string is displayed as the error message for validation

• Request report - use the function that returns the cursor

  My requirement is to create a report, which the source will be a function that returns a cursor (the type of cursor is ref cursor).

  Better to look at a function that returns a query, or use a hose to treat your cursor returned, because the APEX at the moment can NOT handle the sliders in reports...

• How to perform a function and return the result in a variable of liaison

  Hi Kiran and welcome to the forum,

  You mix SQL and PL/SQL

  It's the way in which SQL:

  SQL> SELECT total_income('AD_VP') FROM DUAL;
  
  TOTAL_INCOME('AD_VP')
  ---------------------
                    123
  1 row selected.
  

  It comes to PL/SQL in SQL * more

  SQL> variable test_sal number
  SQL> execute :test_sal := total_income('AD_VP')
  PL/SQL procedure successfully completed.
  SQL> exec dbms_output.put_line('Total Sal:'||:test_sal)
  Total Sal:123
  PL/SQL procedure successfully completed

• That means the result of 'accuracy '?

  Hello

  I created a test exercise - everything is done with scored click boxes, etc - and when I tested it, I got a note of 'precision' of 22%, although I had all the answers right.

  Can someone tell me what the ranking?  Thank you...

  Normally, the accuracy is the percentage score. So, if you create a quiz with point Total = 40, the Score will give you the result in points, p.e. 36 (out of 40) and precision returns the percentage calculated (in this example, 90%). So far I never had problems with this result, but I always publish a LMS and checked the individual results on the various issues. I prefer even the percentage return (in this case, accuracy) of the LMS. I don't know exactly what happened with you. How did you test? Was it after publication?

• Paid the required version for functions that eliminate the details and sensitive information?

  We have downloaded version 11 of Acrobat and we need to remove sensitive information such as the details of the property and anything else relating to the documents that we do not want the end user to see. I know that it is possible to right click the icon of the Office for the paper, but with the help of this process does not remove completely all the information that we want to. I just watch the tutorial on how to remove sensitive information by using the function 'protection' (writing), but I don't see the same list of options on my version of acrobat. My guess is that these features are available on the paid version. Is this the case? Also, is it possible to set up acrobat so that by default, all of the sensitive information in the document and icon properties are deleted? We find that if we create a Word document and remove the icon properties and any other sensitive information, to remove that info again on saving in PDF format. The PDF file displays the info we do not want to send and I have tried different methods to remove the icon properties, but he seems to have no effect. Thank you for your help.

  The writing tool is only available with the professional version of Acrobat.
