Uwagi

Information about XML schema collections is visible in the sys.xml_schema_collections catalog view.

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

XML schema collection permission	Implied by XML schema collection permission	Implied by schema permission
ALTER	CONTROL	ALTER
CONTROL	CONTROL	CONTROL
EXECUTE	CONTROL	EXECUTE
REFERENCES	CONTROL	REFERENCES
TAKE OWNERSHIP	CONTROL	CONTROL
VIEW DEFINITION	CONTROL	VIEW DEFINITION

Permissions
