Hi,
Well how to say, i suggest you to start with theses documentations:

http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/toc.htm
Thenyou'll probably have a better idea of what's an Oracle DB. After that comme back and describe the tools you're using and what's your requirements (what's you want to do, for what purpose...) then may be we'll be able to help you ..

Function which returns multiple values that can then be used in an SQL Sele

I'd like to create a function which returns multiple values that can then be used in an SQL Select statement's IN( ) clause
Currently, the select statement is like (well, this is a very simplified version):
select application, clientid
from tbl_apps, tbl_status
where tbl_apps.statusid = tbl_status.statusid
and tbl_status.approved > 0;
I'd like to pull the checking of the tbl_status into a PL/SQL function so my select would look something like :
select application, clientid
from tbl_apps
where tbl_apps.statusid in (myfunction);
So my function would be running this sql:
select statusid from tbl_status where approved > 0;
... will return values 1, 5, 15, 32 (and more)
... but I haven't been able to figure out how to return the results so they can be used in SQL.
Thanks for any help you can give me!!

Perhaps take a look at pipelined functions:
Single column example:

Plsql use a function which returns a ref cursor

Hi
I've been using an function which returns a ref cursor. I've been returning this into a java resultset. Fine!
Now i'm in plsql and want to use the same function. I'm not sure how to get this resultset in plsql.

It's not very practical to use a refcursor like you want to, but here you go
create or replace function test_ref
return sys_refcursor
is
v_rc sys_refcursor;
begin
open v_rc for select emp_name from emp ;
return v_rc;
end;
declare
v_rc sys_refcursor;
v_emp_name emp.emp_name%type;
begin
v_rc := test_ref ;
loop
    fetch v_rc into v_emp_name ;
    exit when v_rc%notfound ;
    dbms_output.put_line('Employee Name: '||v_emp_name );
end loop;
end;

That isn't enough of a description to know what you are trying to do or how you plan to use the function. The query you provided has no relation to the question you ask.
Are you asking about pipelined functions? Here is an example of that

create or replace function get_emp( p_deptno in number )
return emp_table_type
PIPELINED
as
   TYPE EmpCurTyp IS REF CURSOR RETURN emp%ROWTYPE;
    emp_cv EmpCurTyp;
    l_rec emp%rowtype;

Error while calling the function which returns SQL Query!!!

Hi,
I have a Function which returns SQL query. I am calling this function in my APEX report region source.
The query is dynamic SQL and its size varies based on the dynamic "where clause" condition.
But I am not able to execute this function.It gives me the following error in APEX region source.
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Even in SQL* Plus or SQL developer also same error .
The length of my query is more than 4000. I tried changing the variable size which holds my query in the function.
Earlier it was
l_query varchar2(4000)
Now I changed to
l_query varchar2(32767).
Still it is throwing the same error.
Can anybody help me to resolve this.???
Thanks
Alaka

Hi Varad,
I am already using 32k of varchar2. Then also it is not working.
It is giving the same error. I think there is something to do with buffer size.
My query size is not more than 4200. Even if i give 32k of varchar2 also buffer is able to hold only 3997 size of the query only.
Error is
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Tried CLOB also. It is not working.
Any other solution for this.
Thanks
Alaka

Help creating a formula which returns current date last year

I need help creating a formula which returns the current date last year. I also need it to work during leap years.
Any ideas?

Hi Dagros,
I'm lucky to be a universe designer, I have to do this only once
The easiest way would probably be to use
=RelativeDate(CurrentDate();-365)
So subtractiing 365 to get the same date last year,
but you would need some extra logic for the years with a feb 29 in those 365 days.
=If FormatDate(RelativeDate(CurrentDate();-365);"dd") = FormatDate(CurrentDate();"dd")
Then RelativeDate(CurrentDate();-365)
Else RelativeDate(CurrentDate();-366)
Another question to ask is if you really want the same date last year, or if you also want a really 'same day' so monday compared to monday etc. in this case you would just subtract 364 days and get the day 52 weeks back...
Good luck,
Marianne

Specify two conditions for button type: pl/sql function body return boolean

Hello,
Can anyone help me out with this issue.
I am using Oracle APEX 3.2 version.
I have page zero select list with submit items P0_ITEM1, P0_ITEM2, P0_ITEM3
and i also have a button on page zero. Now I want to make this button conditional
like only show the button only when all the three items are selected. For this I am having the below condition which is working perfectly fine.
Type: PL/SQL function returning boolean.
RETURN NVL(:P0_ITEM1,'%'||'null%') != '%'||'null%' AND
NVL(:P0_ITEM2,'%'||'null%') != '%'||'null%' AND
NVL(:P0_ITEM3,'%'||'null%') != '%'||'null%' ;Now I want to add one more condition to the button --
the condition is that, the buttton should be displayed only on the pages 1,2,3,4
so can anyone please help me out how do i change the code to include the additional condition.
thanks,
Orton

Try:

RETURN NVL(:P0_ITEM1,'%'||'null%') != '%'||'null%' AND
NVL(:P0_ITEM2,'%'||'null%') != '%'||'null%' AND
NVL(:P0_ITEM3,'%'||'null%') != '%'||'null%' AND

Creating a function and return something from an XML file

Hi!
I'm working with timeline actionscript. I want to create a function that loads my xmlfile and returns an xmlobject with the file's content.
This is what I got so far:
my_btn.addEventListener(MouseEvent.CLICK, getXML("myxml.xml")); //1067: Implicit coercion of a value of type void to an unrelated type Function.
function getXML(fn:String):void{
     var infoLoader:URLLoader = new URLLoader();
     infoLoader.addEventListener(Event.COMPLETE, xmlLoaded);
     infoLoader.load(new URLRequest(fn));
     var myXML:XML = xmlLoaded(); //1136: Incorrect number of arguments. Expected 1.
     trace(myXML);
function xmlLoaded(e:Event):XML{
     return e.target.data;
     //trace(e.target.data);
Can anyone take a look and perhaps point me in the right direction?
Thanks

I have never used a listcomponent, so I can only help with the steps before filling it with data.
I think you should at start of your application load the XML with filenames and just after it's completed, e.g. in Event.COMPLETE handler, load all other XMLs looping through filenamesXML, like this
var filenamesXML:XML;
var XMLsToLoad:uint = 0;
function filenamesXMLLoaded(e:Event):void
     filenamesXML = XML(e.target.data);
     XMLsToLoad = filenamesXML.filenames.children().length();
     for (var i:uint =1; i < filenamesXML.filenames.children().length(); i++)
              getXML( filenamesXML.filenames.children()[i] ); // the function from my previous post, don't forget to implement it
//modify the minor xml load handler from the previous post
function xmlLoaded(e:Event):void
     var loadedXML:XML = XML(e.target.data);
     xmlArray.push(loadedXML);
     XMLsToLoad--;
//assign the one click handler to all buttons, a loop here would be quite handy
function clickHandler(e:MouseEvent):void
     if (XMLsToLoad == 0) //check if all xmls have been completely loaded
          switch (e.target.name) // swith by clicked button's instance name
               case "button_1":
                    // here you have to implement supplying listcomponent with data, I think a loop again will be a good idea
                    break;
               case "button_2":
                    // ibid.
                    break;

Use function which returns clob in proceudre

Hello,
I need some help with a function call i am using.
I have a SYSMAN function which i like to call in procedure.
The output from the function is a CLOB.
Executing the statement in SqlPlus returns 2 lines of data, but written into a procedure returns in an error.
The procedure looks like this:
     CREATE OR REPLACE PROCEDURE large_val as
     cSql_text          CLOB;
     sSql_stmt           varchar2(200);
     job_id          varchar2(80);
     exec_id          varchar2(80);
     parm          varchar2(50);
     begin
     job_id := '82A11DD897876D29E0400A0A8A1051A7';
     exec_id := '0000000000000000';
     parm := 'large_sql_script';
     sSql_stmt := 'SELECT SYSMAN.MGMT_JOBS.get_large_param(' || ''''||job_id||'''' ||',' ||''''||exec_id||''''||','||''''||parm|| '''' || ') FROM DUAL;';
     dbms_output.put_line(sSql_stmt);
     execute immediate sSql_stmt into cSql_text;
     END large_val;
The output from dbms_output i am able to run a statement in SqlPlus without error:
     SELECT SYSMAN.MGMT_JOBS.get_large_param('82A11DD897876D29E0400A0A8A1051A7','0000000000000000','large_sql_script') FROM DUAL ;
and it returns 2 lines.
Running it as a procecure show's an error i don't understand.
exec large_val;
BEGIN large_val; END;
ERROR at line 1:
ORA-00911: invalid character
ORA-06512: at "SCHEMTS.LARGE_VAL", line 23

Hope anyone can help me.
Any help is appreciated.

you cannot use CLob with select query.Yes you can. At least since 10gR1, but possibly in earlier versions too.
@OP:
Why aren't you using bind variables? And why are you using dynamic sql at all?
You could just do
cSql_text := SYSMAN.MGMT_JOBS.get_large_param(job_id, exec_id, parm);

How to create one procedure which can drop and create materialized view

What do you hope to achieve by this? A refresh? If so, a simple refresh of the old materialized view will do.
If you truly want to continue this road, you'll have to use the EXECUTE IMMEDIATE command to execute DDL commands from within PL/SQL.

I have specific data that I am looking at that I require to query from a function. This function will require that I specify a parameter for a specific date which will only list the date criteria f my choosing.
Here is the data..
StudentID
FirstName
LastName
ClassName
ClassStartDate
ClassEndDate
GPA

3.25
So here is an example function which will need to be altered. I am hoping someone could help me figure this out. I thought the below may have been correct, but it just errors out.
SET
ANSI_NULLSON
GO
SET
QUOTED_IDENTIFIERON
GO

@startdate
AS
BEGIN
selectFirstName,LastName,ClassName,ClassStartDate,ClassEndDate,GPA
fromdbo.Students
whereClassStartDate
=@startdate
END
GO

Hi Saravana,
If I would to execute this function, how would the parameter be entered?
exec dbo.StudentGPATimePeriod
i think what you need is PROCEDURE, try below
--For a single date
Create PROCEDURE StudentGPATimePeriod
( @startdate datetime )
AS
Begin
select FirstName,LastName,ClassName,ClassStartDate,ClassEndDate,GPA
from dbo.Students
where ClassStartDate >=@startdate and ClassStartDate < dateadd(day,1,@startdate)
End
GO
--for multiple dates
CREATE PROCEDURE getStudentGPAMultipledate
( @startdate datetime,@enddate datetime )
AS
BEGIN
select FirstName,LastName,ClassName,ClassStartDate,ClassEndDate,GPA
from dbo.Students
where ClassStartDate >=@startdate and ClassStartDate < dateadd(day,1,@enddate)
END
GO
EXEC StudentGPATimePeriod @startdate='2014-11-12'
GO
EXEC getStudentGPAMultipledate @startdate='2014-11-12',@enddate='2014-11-13'

Create one function which return boolean
