SHOW CREATE PROCEDURE proc_name

This statement is a MySQL extension. It returns the exact string that can be used to re-create the named stored procedure. A similar statement, SHOW CREATE FUNCTION, displays information about stored functions (see Section 12.4.5.7, “SHOW CREATE FUNCTION Syntax”).

Both statements require that you be the owner of the routine or have SELECT access to the mysql.proc table. If you do not have privileges for the routine itself, the value displayed for the Create Procedure or Create Function field will be NULL.

mysql> SHOW CREATE PROCEDURE test.simpleproc\G
*************************** 1. row ***************************
       Procedure: simpleproc
        sql_mode:
Create Procedure: CREATE PROCEDURE `simpleproc`(OUT param1 INT)
                  BEGIN
                  SELECT COUNT(*) INTO param1 FROM t;
                  END

mysql> SHOW CREATE FUNCTION test.hello\G
*************************** 1. row ***************************
       Function: hello
       sql_mode:
Create Function: CREATE FUNCTION `hello`(s CHAR(20))
                 RETURNS CHAR(50)
                 RETURN CONCAT('Hello, ',s,'!')
