 373     When passed C<$sql>, this function returns an array ref containing a result set
 374     suitably formatted for display in html or for output as a flat file when passed in
 375     C<$format> and C<$id>. It also returns the C<$total> records available for the
 376     supplied query. If passed any query other than a SELECT, or if there is a db error,
 377     C<$errors> an array ref is returned containing the error after this manner:
 378
 379     C<$error->{'sqlerr'}> contains the offending SQL keyword.
 380     C<$error->{'queryerr'}> contains the native db engine error returned for the query.
