This plsql function is considered ok?

This plsql function is considered ok?  The reason that I ask is that the results are different when called within a packet vs appeal during a procedure.  I don't know if this is a bug or if it is illegal.

CREATE OR REPLACE package body test as

function test return varchar2 is
begin
htp.prn('ABCDEF');
return 'xyz';
end;


end;

When this function is called inside a package, the string 'ABCDEF' will appear out of sequence.   I think it's because of the in-Lining, 11 g the function at compile time.

Whereas, when the function is called during a procedure the string 'ABCDEF' appears in the browser html properly.

The service is technically do stuff how to output data from htp.prn, then Oracle can judged illegal.  I have a very good reason for wanting this feature, so before you take a different approach, I wanted to ask around.

The question is how the statements are executed by the PL/SQL engine.

Consider the statement:

HTP.p (' test1 ' |)  FuncTest() ' | 'test2');

To run it, all nested 'objects' must be resolved and executed first. Think of the execution path inside-to-outside.

If FuncTest() is executed first. He puts a string into the buffer of HTP. The result of the function is concatenated and created a unique string literal. This literal is now the parameter in the call to htp.p (). Who then adds, after FuncTest(), a string to the buffer of HTP.

I disagree with your statement that it behaves differently in the procedures as packages. I created 3 test cases for the foregoing. Anonymous block (run immediately the text code execution). Individual objects (separate procedure and function). Single object (procedure and function wrapped in a box).

Each product, as expected, the same result.* how the engine of PL/SQL treats the path of execution of instructions, does not change because the statement is in a packed and not a stand-alone procedure.

  • 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.

  • error in calculation PLSQL function

    Hi friends,

    I have the plsql function below that throw error.

    The function below is written in Apex, if kindly let me know how to solve this error

    The following query checks the existing value and null assigns a value to the select statement. otherwise will assign it to the variable. I don't get how to set dynamically using the select statement

    Hi Pradeep,

    Have you used the suggestion in the post above?
    (Do not use the PL/SQL only the suggested above query block)
    Did you put a semicolon after the query?
    And you always use the PL/SQL code?

    Could you post details of calculation?

    Cordially Pedro.

    Hello

    You can do some tests?
    (1) try to make this code first (to make sure that the P62_EMP_COD is not null when running):

    DECLARE
LINHA NUMBER;
defeito number;
i_emp varchar2(32000);
v_sql2 varchar2(32000);
BEGIN
i_emp := :P62_EMP_COD;

IF :P62_RDD_LIN IS NULL THEN
LINHA:=1;
ELSE
LINHA := :P62_RDD_LIN;
END IF;

v_sql2:='select '||i_emp||'.Grh_1_utils.GRHFU_RUB_DEFAULT('||:P62_ENT_COD||',''R'','||:P62_REM_COD||', 1 , 1000000,''D'',null,to_date('''||:P62_DAT_INI||''',''DD/MM/YYYY''),'||LINHA||') from dual';

EXECUTE IMMEDIATE v_sql2 INTO defeito;
COMMIT;

return defeito;
end;

    (2) then you can try to change your source, by changing 'replacement always of value that exists in the session state' "only when null.

    (3) enter your variable dynamic SQL code and check it out:

    DECLARE
LINHA NUMBER;
defeito number;
i_emp varchar2(32000);
v_sql2 varchar2(32000);
BEGIN
i_emp := :P62_EMP_COD;

IF :P62_RDD_LIN IS NULL THEN
LINHA:=1;
ELSE
LINHA := :P62_RDD_LIN;
END IF;

v_sql2:='select '||i_emp||'.Grh_1_utils.GRHFU_RUB_DEFAULT('||:P62_ENT_COD||',''R'','||:P62_REM_COD||', 1 , 1000000,''D'',null,to_date('''||:P62_DAT_INI||''',''DD/MM/YYYY''),'||LINHA||') from dual';
return v_sql2;
EXECUTE IMMEDIATE v_sql2 INTO defeito;
COMMIT;

return defeito;
end;

    (4) prevent your run immediate code of SQL Injections using the link:

    DECLARE
LINHA NUMBER;
defeito number;
i_emp varchar2(32000);
v_sql2 varchar2(32000);
BEGIN
i_emp := :P62_EMP_COD;

    Hello

    Well, there is still this red asterisk, you cannot enter anything in the text of the error.
    If you leave the field blank, Assistant does not raise any validation error.

  • Need help with rewrite PLSQL function EVALUATE

    Hi all

    I'm trying to convert some PLSQL (from Discoverer) in a column of answers and I can't seem to get the correct formula.

    The original formula:
    MIN (Processed_Date) MORE (SCORE OF Business_Area, product, Serial_No)

    I guess that this must be done in an evaluation function, but I can't work on the correct syntax.

    This formula:
    Evaluate ('MIN (%1) OVER (PARTITION OF 2%, 3%, 4%)) ", Business_Area, Processed_Date, Serial_No, product)
    Has generated this error:
    [nQSError: 10058] A general error occurred. [nQSError: 22027] Union of incompatible types. (HY000)

    I do not know what causes the error, and tried casting explicitly throughout the column, but still getting errors.


    I am open to any suggestion.

    Thank you.

    Jasonr,

    highlighted in bold is the change
    Try this EVALUATE ('MIN (%1) OVER (PARTITION OF 2%, 3%, 4%)) AS the DATE, Processed_Date, Business_Area, product, Serial_No)
    update if it solved your problem.

  • unexpected problem with the permission of type plsql function scheme

    Hello
    I created a schema authorization function plsql type returning a Boolean. Authorization scheme is for pages only. p2_user_priviledge is a textbox control on the home page that retrieves privilege (list of the pagenos) to the user of the database connection. Homepage has no required permissions. SCHEMA AUTHORIZATION always returns false. I am not able to trace problem in my code. same code works fine for failure to the 'c' of return area.

    -CODE OF AUTHORIZATION SCHEME-
    declare
    PageID varchar2 (10);
    VARCHAR2 (300) of privilege;
    c number (3);
    Start
    PageID: = ": P" | to_char(:app_page_id) |': '; -NUMPAGE stored in format *: P2: *
    privilege: = trim(:p2_user_priviledge); ++-List contain privileges like: P2:P13:P67:P23: etc +++ select instr (privilege, pageid) in c to double;
    If c > 0 then
    Returns true;
    on the other
    Returns false;
    end if;
    end;

    ------------------------------------------------------------------------------------------------------------------------------------------

    Another problem is again related to the authorization scheme.
    I created an application and schema of an authorization (auth_aug), which worked fine. Then, after a few days, I added more than 10 pages for the same application, but now autho_aug always returned false for new pages. Then I copied the code from the "autho_aug" to the new "autho_sept" regime, and it worked for new pages. I do not understand if code is the same for both system, why had to use two different schemas.
    Now, I've added a few pages more enforcement and problem mentioned earlier.

    any solution to the two problems...

    Hello

    You can create a component of demand through the shared components in your application, elements of Application option. All you do here is to create a new item and give it a name.

    Once this is done, the element can be used as if it were a page element. You can use an Application (also available through shared components) calculation to set the value of this element in the list of page numbers and the value can then be retrieved in a SQL statement or PL/SQL.

    You cannot use the popup window Session to change elements from page or application - you will need to create a calculation or process to do.

  • Under XP I could search for a string in all the files on my computer. I can't find this search function of SMEs on Windows 7. Anyone?

    On Windows XP, there is a search function to search for a string in any kind of files on your computer. You are looking for a specific name was easy, if you fogort what kind of file, this name occurred in or what it was named.

    On Windows 7 it only allows searching for a name of a file.  How to search for strings in file names?  29/12/12 Paul Figueroa

    Oh, what you want is the content property.

    content: ~ = Figueroa

    [Update: apparently special search symbols such as ~ = do not work with the content when property indexed research places, but work during the search in unindexed locations.]

    I should mention that Windows 7 Search is not case sensitive, so it makes no difference to try to find upper or lower case letters.  In addition, Windows 7 Search is not able to search the contents of files that have no file extension.  There is also a weird question having to watch in Indexing Options to determine which file extensions are defined for content, research, where you have a type of unusual file that is not defined for the content of the search.

    Delete this l_namespace chain, it has nothing to do there, it is not a namespace declaration:

    "xsi: schemaLocation ="http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader PackageProxy.xsd

    As a general rule, simply declare the or - prefixes or by default - you need resolve the XPath expression.

    Once you correct this part, you will discover that your query returns null.

    This is because the XPath expression is not point to any node.

    Try this instead:

    SELECT EXTRACTVALUE)

    VALUE (p)

    , ' / sh: StandardBusinessDocument/sh: StandardBusinessDocumentHeader/sh: HeaderVersion'

    l_namespace

    ) AS IMZA

    TABLE)

    XMLSEQUENCE)

    EXTRACT (x, ' / sh: StandardBusinessDocument', l_namespace)

    )

    ) p
