DROP PROCEDURE

Removes a single stored procedure from the specified database.

Syntax

DROP PROCEDURE [IF EXISTS] { procedure_name | database_name.procedure_name }

Remarks

  • Only one stored procedure can be removed using the DROP PROCEDURE command.

  • If DROP PROCEDURE is executed for a procedure that does not exist, the following error will occur:

    DROP PROCEDURE myprocedure;
    ERROR 1998 (HY000): Function 'db1.myprocedure' doesn't exist
  • However, if the IF EXISTS condition is used and the procedure does not exist, no error will occur:

    DROP PROCEDURE IF EXISTS myprocedure;
    Query OK, 0 rows affected (0.00 sec)
  • This command causes implicit commits. See COMMIT for more information.

  • Refer to the Permission Matrix for the required permission.

Examples
