How to alter a stored procedure in MariaDB?

A Stored Procedure or simply a Procedure is an SQL statement collection enclosed in the CREATE PROCEDURE statement. It needs SQL statements, parameter lists, and a procedure name. Additionally, it also includes conditional sentences like IF, CASE, or the Loops. We can start it using other procedures or apps.

Some of the features of the stored procedure include:

1. It will increase the performance efficiency of the apps.
2. It lessens traffic between the database server and the application.
3. It is reusable.
4. It is more secure than AdHoc queries. Permission can be granted to the user to run it without giving permission to the tables used in the stored procedure.

Syntax to alter the stored procedures in MariaDB

By altering, we are changing its characteristics. We can’t change the body alone. If we need to change, we’ve to delete the procedure and create a new one. For this, we can use either CREATE OR REPLACE PROCEDURE (since MariaDB 10.1.3) or DROP PROCEDURE and CREATE PROCEDURE (MariaDB 10.1.2 and before).

The syntax to change the stored procedure is as follows:

ALTER PROCEDURE proc_name [characteristic ...]

characteristic:
{ CONTAINS SQL | NO SQL | READS SQL DATA | MODIFIES SQL DATA }
| SQL SECURITY { DEFINER | INVOKER }
| COMMENT 'string'

We can change a stored procedure’s attributes using this statement. The statement may specify more than one change. This statement, however, does not allow us to modify a saved procedure’s parameters or body.

For the procedure, we need to have the ALTER ROUTINE privilege. The procedure author automatically receives that privilege by default.
