Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

Revokes permissions on a schema.

Transact-SQL syntax conventions

Syntax

  
REVOKE [ GRANT OPTION FOR ] permission  [ ,...n ]   
    ON SCHEMA :: schema_name   
    { TO | FROM } database_principal [ ,...n ]  
    [ CASCADE ]  
    [ AS revoking_principal ]

Arguments

permission
Specifies a permission that can be revoked on a schema. The permissions that can be revoked on a schema are listed in the "Remarks" section, later in this topic.

GRANT OPTION FOR
Indicates that the right to grant the specified right to other principals will be revoked. The permission itself will not be revoked.

Important

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

ON SCHEMA :: schema*_name*
Specifies the schema on which the permission is being revoked. The scope qualifier :: is required.

database_principal
Specifies the principal from which the permission is being revoked. One of the following:

  • database user

  • database role

  • application role

  • database user mapped to a Windows login

  • database user mapped to a Windows group

  • database user mapped to a certificate

  • database user mapped to an asymmetric key

  • database user not mapped to a server principal.

CASCADE
Indicates that the permission being revoked is also revoked from other principals to which it has been granted by this principal.

Caution

Indicates that the permission being revoked is also revoked from other principals to which it has been granted or denied by this principal.

AS revoking_principal
Specifies a principal from which the principal executing this query derives its right to revoke the permission. One of the following:

  • database user

  • database role

  • application role

  • database user mapped to a Windows login

  • database user mapped to a Windows group

  • database user mapped to a certificate

  • database user mapped to an asymmetric key

  • database user not mapped to a server principal.

Remarks

A schema is a database-level securable contained by the database that is its parent in the permissions hierarchy. The most specific and limited permissions that can be revoked on a schema are listed in the following table, together with the more general permissions that include them by implication.

Schema permission Implied by schema permission Implied by database permission
ALTER CONTROL ALTER ANY SCHEMA
CONTROL CONTROL CONTROL
CREATE SEQUENCE ALTER ALTER ANY SCHEMA
DELETE CONTROL DELETE
EXECUTE CONTROL EXECUTE
INSERT CONTROL INSERT
REFERENCES CONTROL REFERENCES
SELECT CONTROL SELECT
TAKE OWNERSHIP CONTROL CONTROL
UPDATE CONTROL UPDATE
VIEW CHANGE TRACKING CONTROL CONTROL
VIEW DEFINITION CONTROL VIEW DEFINITION

Permissions

Requires CONTROL permission on the schema.
