The CREATE ROUTINE privilege is needed to create stored routines.

The ALTER ROUTINE privilege is needed to alter or drop stored routines. This privilege is granted automatically to the creator of a routine if necessary, and dropped from the creator when the routine is dropped.

The EXECUTE privilege is required to execute stored routines. However, this privilege is granted automatically to the creator of a routine if necessary (and dropped from the creator when the routine is dropped). Also, the default SQL SECURITY characteristic for a routine is DEFINER, which enables users who have access to the database with which the routine is associated to execute the routine.

If the automatic_sp_privileges system variable is 0, the EXECUTE and ALTER ROUTINE privileges are not automatically granted to and dropped from the routine creator.

The creator of a routine is the account used to execute the CREATE statement for it. This might not be the same as the account named as the DEFINER in the routine definition.

The account named as a routine DEFINER can see all routine properties, including its definition. The account thus has full access to the routine output as produced by:

For an account other than the account named as the routine DEFINER, access to routine properties depends on the privileges granted to the account:
