[HELP] Procedure return records

Question

Hi All,
I want to create a procedure that will return records (not only single record) base on some parameters. Is it possible?
While i used MS SQL Server, it is just a simple way. In the body of procedure i just need to call select query with some parameters in where clause. For example:
Create procedure GetEmployee
@grade char(1)
As
Select * From Employee Where EMP_Grade=@grade
Please help me!

Answer 1

First off, what are you going to do with the records that are returned here?
Second, you can return a REF CURSOR
CREATE OR REPLACE PACKAGE refcursor_demo
AS
  TYPE emp_refcursor_strong IS REF CURSOR RETURN emp%rowtype;
  TYPE emp_refcursor_weak   IS REF CURSOR;
  -- You can define either procedures that have the strongly typed
  -- REF CURSOR as an OUT parameter or you can define a function that
  -- returns the REF CURSOR.
  PROCEDURE refCursorProc( employees OUT emp_refcursor_strong );
  FUNCTION  refCursorFunc RETURN emp_refcursor_weak;
END;
CREATE OR REPLACE PACKAGE BODY refcursor_demo
AS
  PROCEDURE refCursorProc( employees OUT emp_refcursor_strong )
  AS
  BEGIN
    OPEN employees FOR
      SELECT * FROM emp;
  END;
  FUNCTION refCursorFunc RETURN emp_refcursor_weak
  IS
    out_cursor emp_refcursor_weak;
  BEGIN
    OPEN out_cursor FOR
      SELECT * FROM emp;
    RETURN out_cursor;
  END;
END;Alternately, you could return a collection, potentially in a pipelined table function.
