[!INCLUDE[tsql-appliesto-ss2008-xxxx-xxxx-xxx-md](../../includes/tsql-appliesto-ss2008-xxxx-xxxx-xxx-md.md)]

## Syntax  
  
```  
  
DROP XML SCHEMA COLLECTION [ relational_schema. ]sql_identifier  
```  
  
## Arguments  
 *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.  
  
## Remarks  
 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.  
  
    ```  
    CREATE FUNCTION dbo.MyFunction()  
    RETURNS int  
    WITH SCHEMABINDING  
    AS  
    BEGIN  
       ...  
       DECLARE @x XML(MyCollection)  
       ...  
    END;  
    ```  
  
## Permissions  
 To drop an XML SCHEMA COLLECTION requires DROP permission on the collection.  
  
## Examples  
 The following example shows removing an XML schema collection.  
  
```  
DROP XML SCHEMA COLLECTION ManuInstructionsSchemaCollection;  
GO  
```
