Transact-SQL Syntax Conventions

Simplified syntax for REVOKE
REVOKE [ GRANT OPTION FOR ]
      { 
        [ ALL [ PRIVILEGES ] ]
        |
                permission [ ( column [ ,...n ] ) ] [ ,...n ]
      }
      [ ON [ class :: ] securable ] 
      { TO | FROM } principal [ ,...n ] 
      [ CASCADE] [ AS principal ]

Arguments

• GRANT OPTION FOR
  Indicates that the ability to grant the specified permission will be revoked. This is required when you are using the CASCADE argument.

  Ważne:
  If the principal has the specified permission without the GRANT option, the permission itself will be revoked.

• ALL
  This option does not revoke all possible permissions. Revoking ALL is equivalent to revoking 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.

  [!UWAGA]

  The REVOKE ALL syntax is deprecated. This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Revoke specific permissions instead.

• PRIVILEGES
  Included for ISO compliance. Does not change the behavior of ALL.

• permission
  Is the name of a permission. The valid mappings of permissions to securables are described in the topics listed in Securable-specific Syntax later in this topic.

• column
  Specifies the name of a column in a table on which permissions are being revoked. The parentheses are required.

• class
  Specifies the class of the securable on which the permission is being revoked. The scope qualifier :: is required.

• securable
  Specifies the securable on which the permission is being revoked.

• TO | FROM principal
  Is the name of a principal. The principals from which permissions on a securable can be revoked vary, depending on the securable. For more information about valid combinations, see the topics listed in Securable-specific Syntax later in this topic.

• CASCADE
  Indicates that the permission that is being revoked is also revoked from other principals to which it has been granted by this principal. When you are using the CASCADE argument, you must also include the GRANT OPTION FOR argument.

  Przestroga
  A cascaded revocation of a permission granted WITH GRANT OPTION will revoke both GRANT and DENY of that permission.

• AS principal
  Specifies a principal from which the principal executing this query derives its right to revoke the permission.

Uwagi

The full syntax of the REVOKE statement is complex. The syntax diagram above was simplified to draw attention to its structure. Complete syntax for revoking permissions on specific securables is described in the topics listed in Securable-specific Syntax later in this topic.

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. However, revoking the granted permission at a higher scope does not take precedence.

Przestroga
A table-level DENY does not take precedence over a column-level GRANT. This inconsistency in the permissions hierarchy has been preserved for backward compatibility. It will be removed in a future release.

The sp_helprotect system stored procedure reports permissions on a database-level securable

The REVOKE statement will fail if CASCADE is not specified when you are revoking a permission from a principal that was granted that permission with GRANT OPTION specified.

Permissions

Principals with CONTROL permission on a securable can revoke permission on that securable. Object owners can revoke permissions on the objects they own.

Grantees of CONTROL SERVER permission, such as members of the sysadmin fixed server role, can revoke 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 revoke any permission on any securable in the database. Grantees of CONTROL permission on a schema can revoke any permission on any object within the schema.
