[sql] Call a stored procedure with another in Oracle

Does anyone know of a way, or even if its possible, to call a stored procedure from within another? If so, how would you do it?

Here is my test code:

SET SERVEROUTPUT ON;

DROP PROCEDURE test_sp_1;
DROP PROCEDURE test_sp;

CREATE PROCEDURE test_sp
AS
BEGIN
    DBMS_OUTPUT.PUT_LINE('Test works');
END;
/

CREATE PROCEDURE test_sp_1
AS
BEGIN
    DBMS_OUTPUT.PUT_LINE('Testing');
    test_sp;
END;
/

CALL test_sp_1;

Sure, you just call it from within the SP, there's no special syntax.

Ex:

   PROCEDURE some_sp
   AS
   BEGIN
      some_other_sp('parm1', 10, 20.42);
   END;

If the procedure is in a different schema than the one the executing procedure is in, you need to prefix it with schema name.

   PROCEDURE some_sp
   AS
   BEGIN
      other_schema.some_other_sp('parm1', 10, 20.42);
   END;

@Michael Lockwood - you don't need to use the keyword "CALL" anywhere. You just need to mention the procedure call directly.

That is

Begin
   proc1(input1, input2);
end;
/

instead of

Begin
   call proc1(input1, input2);
end;
/

Calling one procedure from another procedure:

One for a normal procedure:

CREATE OR REPLACE SP_1() AS 
BEGIN
/*  BODY */
END SP_1;

Calling procedure SP_1 from SP_2:

CREATE OR REPLACE SP_2() AS
BEGIN
/* CALL PROCEDURE SP_1 */
SP_1();
END SP_2;

Call a procedure with REFCURSOR or output cursor:

CREATE OR REPLACE SP_1
(
oCurSp1 OUT SYS_REFCURSOR
) AS
BEGIN
/*BODY */
END SP_1;

Call the procedure SP_1 which will return the REFCURSOR as an output parameter

CREATE OR REPLACE SP_2 
(
oCurSp2 OUT SYS_REFCURSOR
) AS `enter code here`
BEGIN
/* CALL PROCEDURE SP_1 WITH REF CURSOR AS OUTPUT PARAMETER */
SP_1(oCurSp2);
END SP_2;

To invoke the procedure from the SQLPlus command line, try one of these:

CALL test_sp_1();
EXEC test_sp_1
