27.2.2 存储例程和 MySQL 权限
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 defaultSQL SECURITY
characteristic for a routine isDEFINER
, 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, 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 the
CREATE
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 Schema
ROUTINES
table. -
The
SHOW CREATE FUNCTION
andSHOW CREATE PROCEDURE
statements. -
The
SHOW FUNCTION CODE
andSHOW PROCEDURE CODE
statements. -
The
SHOW FUNCTION STATUS
andSHOW PROCEDURE STATUS
statements.
-
-
For an account other than the account named as the routine
DEFINER
, 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.
