public class NullUpdateException
extends SQLException

An exception thrown when no update will be issued because of metadata settings. `WLCachedRowSet.acceptChanges`

After calling acceptChanges, WLRowSetMetaData will be checked to decide where to write back the changes. If writeTable was set and there is no column associated with it, no changes will be written back to the data source and NullUpdateException will be thrown. In most case it is a real exception that is caused by the misconfiguration of WLRowSetMetaData. This exception helps application detect their problem earlier. Application can catch this exception and ignore it if they are aware of this case.
