Remarks

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 granted 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

The grantor (or the principal specified with the AS option) must have either the permission itself with GRANT OPTION, or a higher permission that implies the permission being granted.

If you are using the AS option, the following additional requirements apply.

AS	Additional permission required
Database user	IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a Windows login	IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a Windows group	Membership in the Windows group, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a certificate	Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to an asymmetric key	Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user not mapped to any server principal	IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database role	ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Application role	ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.

Examples

The following example grants EXECUTE permission on the XML schema collection Invoices4 to the user Wanida. The XML schema collection Invoices4 is located inside the Sales schema of the AdventureWorks2008R2 database.

USE AdventureWorks2008R2;

GRANT EXECUTE ON XML SCHEMA COLLECTION::Sales.Invoices4 TO Wanida;

GO
