Revoke Method (Table, View)

Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.

The Revoke method undoes a grant or deny of a table permission or a list of permissions for one or more Microsoft SQL Server users or roles.

Syntax

object.Revoke(Privilege,GranteeNames, [ ColumnNames ] ,
[ GrantGrant ] , [ RevokeGrantOption ] , [ AsRole ] )

Parts

• object
  Expression that evaluates to an object in the Applies To list.

• Privilege
  Long integer that specifies one or more table privileges as described in Settings.

• GranteeNames
  SQL Distributed Management Objects (SQL-DMO) multistring that lists users or roles.

• ColumnNames
  SQL-DMO multistring that lists columns within the base or view table referenced. When specified, the privileges specified are revoked for only the columns named.

• GrantGrant
  When TRUE, the grantee(s) specified are granted the ability to execute the REVOKE statement referencing the base or view table. When FALSE (default), the ability to limit permission is not granted.

• RevokeGrantOption
  When TRUE, the ability to extend permission is revoked. When FALSE (default), no change is made to the ability to extend permission.

• AsRole
  String that identifies a role to which the connected user belongs as described in Remarks.

Prototype (C/C++)

HRESULT Revoke(
SQLDMO_PRIVILEGE_TYPE iPrivileges,
SQLDMO_LPCSTR GranteeNames,
SQLDMO_LPCSTR ColumnNames = NULL,
BOOL GrantGrant = FALSE,
BOOL RevokeGrantOption = FALSE,
SQLDMO_LPCSTR AsRole = NULL);

Settings

Set the Privilege argument by using these values. To specify more than a single permission, combine values by using an OR logical operator.

Constant	Value	Description
SQLDMOPriv_AllObjectPrivs	63	Revoke all granted or denied table permissions.
SQLDMOPriv_Delete	8	Revoke granted or denied permission to execute the DELETE statement referencing the table.
SQLDMOPriv_Insert	2	Revoke granted or denied permission to execute the INSERT statement referencing the table.
SQLDMOPriv_References	32	Revoke granted or denied permission to reference the table in statements implementing declarative referential integrity.
SQLDMOPriv_Select	1	Revoke granted or denied permission to execute the SELECT statement referencing the table.
SQLDMOPriv_Update	4	Revoke granted or denied permission to execute the UPDATE statement referencing the table.

Hinweise

When a user is a member of more than a single role, the user can have permission to grant access to a table or view under one role and not under another. In this case, SQL Server security mechanisms prevent execution of the Revoke method on the Table or View object referencing the database object. Use the AsRole argument to specify the role under which permission to execute the grant exists.

Undoing a grant or deny of a permission to database users and roles by using the Revoke method of the Table or View object requires appropriate privilege. The SQL Server login used for SQLServer object connection must be granted the ability to execute GRANT referencing the database object, the owner of the database object, or a member of a role with greater privilege.
