DROP PROCEDURE - MySQL

DROP PROCEDURE

MySQL command to remove a previously created stored procedure.

Syntax

DROP PROCEDURE [IF EXISTS] `db_name`.`procedure_name`

Options/Flags

  • IF EXISTS: Optionally checks if the procedure exists before attempting to drop it. If the procedure doesn’t exist, no error is raised.

Examples

  • Drop a stored procedure named get_customer_orders:
DROP PROCEDURE `db_name`.`get_customer_orders`;
  • Safely drop the procedure, avoiding errors if it doesn’t exist:
DROP PROCEDURE IF EXISTS `db_name`.`get_customer_orders`;

Common Issues

  • Procedure not found: Ensure the specified procedure name and database name are correct.
  • Dependent objects: If objects (such as views or triggers) depend on the procedure, they must be dropped first.

Integration

  • CREATE PROCEDURE: Used to initially create a stored procedure.
  • CALL: Executes a stored procedure.
  • SHOW PROCEDURES: Lists all stored procedures in the database.
