This section describes stored procedures for Cloud SQL instances. A stored procedure contains SQL code that you can reuse. > [!NOTE] > You cannot drop or alter system stored procedures. To execute a stored procedure, you use the `CALL` command and replace the following variable: - procedure_name is the name of the stored procedure. ```sql CALL procedure_name(parameters); ``` For more information, see the [CALL](https://www.postgresql.org/docs/current/static/sql-call.html) reference page.
To create your own stored procedure, see [CREATE PROCEDURE](https://www.postgresql.org/docs/current/static/sql-createprocedure.html).
