/**
* An exception that provides information on database access
* warnings. Warnings are silently chained to the object whose method
* caused it to be reported.
*
* Warnings may be retrieved from Connection, Statement,
* and ResultSet objects. Trying to retrieve a warning on a
* connection after it has been closed will cause an exception to be thrown.
* Similarly, trying to retrieve a warning on a statement after it has been
* closed or on a result set after it has been closed will cause
* an exception to be thrown. Note that closing a statement also
* closes a result set that it might have produced.
