Returning row count using Stored Procedure.

Question

I have the following stored procedure.
create or replace
PROCEDURE CHECK_DER_OUTPUT (dummy IN VARCHAR2) AS
recordCount NUMBER;
BEGIN
SELECT COUNT(*) into recordCount FROM ICS_TEMP_DERIVATIVE WHERE ALLOCATIONTYPE in ('Aggregate','Non Aggregate');
END ;
All I need to return the count as an ResultSet? Is this possible?
Help appreciated !

Answer 1

A procedure can return an OUT parameter, i.e.
CREATE OR REPLACE PROCEDURE check_der_output (
  p_dummy IN varchar2,
  p_recordCount OUT number )
AS
BEGIN
  SELECT COUNT(*)
    INTO p_recordCount
    FROM ics_temp_derivative
   WHERE allocationType IN ('Aggregate', 'Non Aggregate' );
END;Or you could write a function that returns the number
CREATE OR REPLACE FUNCTION check_der_output (
  p_dummy IN varchar2 )
    RETURN NUMBER
IS
  l_recordCount number;
BEGIN
  SELECT COUNT(*)
    INTO l_recordCount
    FROM ics_temp_derivative
   WHERE allocationType IN ('Aggregate', 'Non Aggregate' );
  RETURN( l_recordCount );
END;Justin
