Showing results from oracle 10g stored procedure

Question

I use PL / SQL Developer, and I wrote a procedure to run a report, and I need a procedure to output a result set.

The procedure accepts input parameters and should output a set of results.

I cannot use the view because the procedure calls several APIs that accept the parameters that I pass to the procedure.

I understand from many searches that ref_cursor is possible, but I can't get ti to work.

Simplified version of the procedure:

CREATE OR REPLACE PROCEDURE IFSINFO.SHORTAGE_SHEET (vSite     IN VARCHAR2,
                                                    vBuyer    IN VARCHAR2,
                                                    vSupplier IN VARCHAR2,
                                                    vCursor   OUT SYS_REFCURSOR)   
AS                                                    
BEGIN
    OPEN vCursor FOR                   
        SELECT blah blah blah blah blah blah;
END;

I tried to execute the procedure and display the results using:

BEGIN
    vsite       := 'S03';
    vbuyer      := 'AW';
    vsupplier   := '%';    
    vcursor     refcursor;

    IFSINFO.SHORTAGE_SHEET(vsite => :vsite,
                           vbuyer => :vbuyer,
                           vsupplier => :vsupplier,
                           vcursor => :vcursor);                           
    print vcursor;                           
END;

And:

variable rc refcursor; 
exec IFSINFO.SHORTAGE_SHEET('S03','AW','TQ1',:rc2); 
print rc2

But nobody is working. please someone can advise that i am at my end.

Thank. Rob

pl/sql .

CREATE OR REPLACE TYPE ABC.TEST_TYPE
AS OBJECT
( 
  "Site"                       VARCHAR2(25),
);

CREATE OR REPLACE TYPE ABC.TEST_COL 
    AS TABLE OF ABC.TEST_TYPE

excute SQL

CREATE OR REPLACE PACKAGE ABC.TEST_RPT AS
    FUNCTION get_report(vPart     VARCHAR2,
                        vBuyer    VARCHAR2,
                        vSupplier VARCHAR2) RETURN ABC.TEST_COL 
    PIPELINED;
END;

, SQL

CREATE OR REPLACE PACKAGE BODY ABC.TEST_RPT AS
  FUNCTION get_report(vPart     VARCHAR2,
                      vBuyer    VARCHAR2,
                      vSupplier VARCHAR2) RETURN ABC.TEST_COL 
    PIPELINED IS
    CURSOR cTest(vPart     VARCHAR2,
                 vBuyer    VARCHAR2,
                 vSupplier VARCHAR2) IS

          SELECT Site
            FROM table
           WHERE Part = vPart
             AND Buyer = vBuyer
             AND Supplier = vSupplier;



  BEGIN
    FOR part_rec IN cTest(vSite, vBuyer, vSupplier) LOOP
      PIPE ROW(ABC.TEST_TYPE(part_rec.Site));

    END LOOP;
    RETURN;
    CLOSE cTest;
  END;
END;

SELECT * FROM TABLE (ABC.TEST_RPT.get_report ('', '', ''))

, SQLPLUS? sqlplus ?

PRINT - sqlplus, . , .

                           o_cursor   => vcursor);

":" , ( SQLPLUS, sqlplus "rc" )

Answer 3

, Sql Plus . refcursor Sql Plus.

variable vcursor refcursor

Then execute the anonymous pl / sql block. Pay attention to the keyword declare.

DECLARE
          vsite       := 'S03';
          vbuyer      := 'AW';
          vsupplier   := '%';
          -- do not declare this, use sql plus bind var     vcursor     refcursor;
BEGIN

       IFSINFO.SHORTAGE_SHEET(vsite => vsite, -- no colon
              vbuyer =>    vbuyer,
              vsupplier => vsupplier,
              vcursor   => :vcursor); 
END;
/

Then run this sql plus command.

print vcursor

print is not pl / sql

Answer 4

Your cursor variable is ref rc. But then you use rc2.

Change rc2to rcand it should work
