Detailed Description
Database error base class.
Catching and silencing this class or its subclasses is strongly discouraged. Most code should not catch DB errors at all, but let them bubble to the MediaWiki exception handler. If necessary, cleanup can be done in a finally block; catching the exception and then rethrowing it is also acceptable.
