Description

Currently the DBCommand implementation does not support delete with joins. Instead in this case an invalid statement is produced. 

However some database systems allow delete operations with joins. This must be implemented in the corresponding driver.

Instead of returning an invalid statement if not implemented by the driver, a default syntax , taken from the SQL Server syntax, should be used.
