Remarks

A schema is a database-level securable. It's contained by the database that is its parent in the permissions hierarchy. The most specific and limited permissions that can be denied on a schema are listed in the following table. The table shows 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. If you're using the AS option, the specified principal must own the schema.
