Use of Pipelined Function in Forms10g(10.1.0.2)...

Question

Hi ,
I test the routines found in http://sheikyerbouti.developpez.com/recordset/record_set.htm
I have a problem in the sample routine in Forms10g regarding pipelined function.
Whereas , the whole routine database part and client side in SQL*PLUS works fine.... the client side on Forms10g does not.......
I used two versions in when-button-pressed trigger:
1)Declare
        cur SYS_REFCURSOR ;
begin
       Open cur for SELECT * FROM  TABLE(Pkg_Cur_.Get_Raws2(CURSOR(SELECT * FROM EMP WHERE DEPTNO = 10)));
end;
The error message in compilation time is..
Error 606: The subquery cursor is invalid in the client side
and the second version is:
2)Declare
      tab Pkg_Cur_.REC_EMP_;
begin
       tab:=Pkg_Cur_.GET_RAWS2('SELECT * FROM EMP WHERE DEPTNO = 10');
end;whereas the database package is defined as:
CREATE OR REPLACE PACKAGE Pkg_Cur_
IS
  TYPE REC_EMP_ IS TABLE OF EMP%ROWTYPE INDEX BY BINARY_INTEGER ;
  FUNCTION Get_Raws RETURN REC_EMP_ ;
  FUNCTION Get_Raws2 ( cur_lig IN SYS_REFCURSOR )
    RETURN TYPE_TAB_REC_EMP_ PIPELINED ;
END  Pkg_Cur_ ;and the database package body is as follows:
CREATE OR REPLACE PACKAGE BODY Pkg_Cur_
IS
  FUNCTION Get_Raws RETURN REC_EMP_
  IS
     TAB REC_EMP_;
  BEGIN
     SELECT * BULK COLLECT INTO TAB FROM EMP ;
       RETURN TAB ;
  END ;
  FUNCTION Get_Raws2 ( cur_lig IN SYS_REFCURSOR )
  RETURN TYPE_TAB_REC_EMP_ PIPELINED
  IS
   Trec  TYPE_REC_EMP_ := TYPE_REC_EMP_(NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL ) ;
   Remp  EMP%ROWTYPE ;
  BEGIN
   LOOP
     FETCH cur_lig INTO Remp ;
     EXIT WHEN cur_lig%NOTFOUND ;
       -- Handling datas --
       Trec.EMPNO    := Remp.EMPNO ;
       Trec.ENAME    := Remp.ENAME ;
       Trec.JOB      := Remp.JOB ;
       Trec.MGR      := Remp.MGR ;
       Trec.HIREDATE := Remp.HIREDATE ;
       Trec.SAL      := Remp.SAL * 1.1 ;
       Trec.COMM     := Remp.COMM ;
       Trec.DEPTNO   := Remp.DEPTNO ;
       -- Return value --
       PIPE ROW( Trec ) ;
   END LOOP ;
   RETURN ;
  END ;
END  Pkg_Cur_ ;
So , how the form trigger should be written...????
If somebody could help me i would be grateful...!!!!
Thanks a lot
Simon

Answer 1

In the second anonymous block you're trying to populate a record with a table. You would need to select from the function and either bulk collect into a table variable or fetch into a record variable in a loop. Bulk collect is also not supported on the client side.
I've been looking at pipelined function possibilities in another thread:
table functions
The problem you have is actually with the Cursor functions, not the Pipelined functions.
