DROP XML SCHEMA COLLECTION (Transact-SQL)

relational_schema

Identifies the relational schema name. If not specified, the default relational schema is assumed.

sql_identifier

Is the name of the XML schema collection to drop.

Dropping an XML schema collection is a transactional operation. This means when you drop an XML schema collection inside a transaction and later roll back the transaction, the XML schema collection is not dropped.

You cannot drop an XML schema collection when it is in use. This means that the collection being dropped cannot be any of the following:

• Associated with any xml type parameter or column.

• Specified in any table constraints.

• Referenced in a schema-bound function or stored procedure. For example, the following function will lock the XML schema collection MyCollection because the function specifies WITH SCHEMABINDING. If you remove it, there is no lock on the XML SCHEMA COLLECTION.

  Copy

  CREATE FUNCTION dbo.MyFunction()
  RETURNS int
  WITH SCHEMABINDING
  AS
  BEGIN
     ...
     DECLARE @x XML(MyCollection)
     ...
  END
  

To drop an XML SCHEMA COLLECTION requires DROP permission on the collection.

For more information, see Permissions on an XML Schema Collection.

The following example shows removing an XML schema collection.
