27.2.2 Stored Routines and MySQL Privileges

The MySQL grant system takes stored routines into account as follows:

• 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 theautomatic_sp_privileges system variable is 0, theEXECUTE andALTER ROUTINE privileges are not automatically granted to and dropped from the routine creator.
• The creator of a routine is the account used to execute theCREATE statement for it. This might not be the same as the account named as theDEFINER 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:
  • The contents of the Information SchemaROUTINES table.
  • The SHOW CREATE FUNCTION and SHOW CREATE PROCEDURE statements.
  • The SHOW FUNCTION CODE andSHOW PROCEDURE CODE statements.
  • The SHOW FUNCTION STATUS and SHOW PROCEDURE STATUS statements.
• For an account other than the account named as the routineDEFINER, access to routine properties depends on the privileges granted to the account:
  • With the SHOW_ROUTINE privilege or the globalSELECT privilege, the account can see all routine properties, including its definition.
  • With the CREATE ROUTINE,ALTER ROUTINE orEXECUTE privilege granted at a scope that includes the routine, the account can see all routine properties except its definition.
