MySQL 8.0 Reference Manual  /  ...  /  SHOW CREATE PROCEDURE Statement

13.7.7.9 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 13.7.7.8, “SHOW CREATE FUNCTION Statement”).

To use either statement, you must be the user named as the routine DEFINER, have the SHOW_ROUTINE privilege, have the SELECT privilege at the global level, or have the CREATE ROUTINE, ALTER ROUTINE, or EXECUTE privilege granted at a scope that includes the routine. The value displayed for the Create Procedure or Create Function field is NULL if you have only CREATE ROUTINE, ALTER ROUTINE, or EXECUTE.

character_set_client is the session value of the character_set_client system variable when the routine was created. collation_connection is the session value of the collation_connection system variable when the routine was created. Database Collation is the collation of the database with which the routine is associated.
