Syntax
Simplified syntax for GRANT
GRANT { ALL [ PRIVILEGES ] }
| permission [ (column [ ,...n ] ) ] [ ,...n ]
[ ON [ class:: ] securable ] TO principal [ ,...n ]
[ WITH GRANT OPTION ] [ AS principal ]
Arguments
ALL
This option is deprecated and maintained only for backward compatibility. It does not grant all possible permissions. Granting ALL is equivalent to granting the following permissions.If the securable is a database, ALL means BACKUP DATABASE, BACKUP LOG, CREATE DATABASE, CREATE DEFAULT, CREATE FUNCTION, CREATE PROCEDURE, CREATE RULE, CREATE TABLE, and CREATE VIEW.
If the securable is a scalar function, ALL means EXECUTE and REFERENCES.
If the securable is a table-valued function, ALL means DELETE, INSERT, REFERENCES, SELECT, and UPDATE.
If the securable is a stored procedure, ALL means EXECUTE.
If the securable is a table, ALL means DELETE, INSERT, REFERENCES, SELECT, and UPDATE.
If the securable is a view, ALL means DELETE, INSERT, REFERENCES, SELECT, and UPDATE.
PRIVILEGES
Included for ISO compliance. Does not change the behavior of ALL.permission
The name of a permission. The valid mappings of permissions to securables are described in the sub-topics listed below.column
Specifies the name of a column in a table on which permissions are being granted. The parentheses ( ) are required.class
Specifies the class of the securable on which the permission is being granted. The scope qualifier**::** is required.securable
Specifies the securable on which the permission is being granted.TO principal
The name of a principal. The principals to which permissions on a securable can be granted vary, depending on the securable. See the sub-topics listed below for valid combinations.GRANT OPTION
Indicates that the grantee will also be given the ability to grant the specified permission to other principals.AS principal
Specifies a principal from which the principal executing this query derives its right to grant the permission.
Remarks
The full syntax of the GRANT statement is complex. The syntax diagram above has been simplified to draw attention to its structure. Complete syntax for granting permissions on specific securables is described in the topics listed below.
The REVOKE statement can be used to remove granted permissions, and the DENY statement can be used to prevent a principal from gaining a specific permission through a GRANT.
Granting a permission removes DENY or REVOKE of that permission on the specified securable. If the same permission is denied at a higher scope that contains the securable, the DENY takes precedence. But revoking the granted permission at a higher scope does not take precedence.
Database-level permissions are granted within the scope of the specified database. If a user needs permissions to objects in another database, create the user account in the other database, or grant the user account access to the other database, as well as the current database.
Warning
A table-level DENY does not take precedence over a column-level GRANT. This inconsistency in the permissions hierarchy has been preserved for the sake of backward compatibility. It will be removed in a future release.
The sp_helprotect system stored procedure reports permissions on a database-level securable.
Permissions
The grantor (or the principal specified with the AS option) must have either the permission itself with GRANT OPTION, or a higher permission that implies the permission being granted. If using the AS option, additional requirements apply. See the securable-specific topic for details.
Object owners can grant permissions on the objects they own. Principals with CONTROL permission on a securable can grant permission on that securable.
Grantees of CONTROL SERVER permission, such as members of the sysadmin fixed server role, can grant any permission on any securable in the server. Grantees of CONTROL permission on a database, such as members of the db_owner fixed database role, can grant any permission on any securable in the database. Grantees of CONTROL permission on a schema can grant any permission on any object within the schema.
