Anyway, hate to do this to you, but you should have RTFM'ed:

`RaiseError' (boolean, inherited)
   The `RaiseError' attribute can be used to force errors
   to raise exceptions rather than simply return error
   codes in the normal way. It is "off" by default.  When
   set "on", any method which results in an error will
   cause the DBI to effectively do a `die("$class $method
   failed: $DBI::errstr")', where `$class' is the driver
   class and `$method' is the name of the method that
   failed. E.g.,

     DBD::Oracle::db prepare failed: ... error text here ...

   If you turn `RaiseError' on then you'd normally turn
   `PrintError' off.  If `PrintError' is also on, then
   the `PrintError' is done first (naturally).
