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.
| Table Object | View Object |
object.Revoke( Privilege , GranteeNames , [ ColumnNames ] ,
[ GrantGrant ] , [ RevokeGrantOption ] , [ AsRole ] )
| Part | Description |
|---|---|
| object | Expression that evaluates to an object in the Applies To list. |
| Privilege | Long integer specifying one or more table privileges as described in Settings. |
| GranteeNames | SQL-DMO multistring listing users or roles. |
| ColumnNames | SQL-DMO multistring listing 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 identifying a role to which the connected user belongs as described in Remarks. |
Set the Privilege argument by using these values. To specify more than a single permission, combine values by using an Or.
| Constant | Value | Description |
|---|---|---|
| SQLDMOPriv_AllObjectPrivs | 63 | Revoke all granted or denied table privileges |
| 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 |
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.
