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 |
