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