13.7.5.9 SHOW CREATE PROCEDURE Statement

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 13.7.5.8, “SHOW CREATE FUNCTION Statement”).

To use either statement, you must be the user named in the routine DEFINER clause or haveSELECT access to themysql.proc table. If you do not have privileges for the routine itself, the value displayed for theCreate Procedure or Create Function column is NULL.
