Remarks

A schema is a database-level securable that is 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, together with the more general permissions that include them by implication.

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

Permissions

Requires CONTROL permission on the schema. If you are using the AS option, the specified principal must own the schema.
