 432 This function returns a DBI statement handler from which the caller can
 433 fetch the results of the SQL passed via C<$sql>.
 434
 435 If passed any query other than a SELECT, or if there is a DB error,
 436 C<$errors> is returned, and is a hashref containing the error after this
 437 manner:
 438
 439 C<$error->{'sqlerr'}> contains the offending SQL keyword.
 440 C<$error->{'queryerr'}> contains the native db engine error returned
 441 for the query.
 442
 443 C<$offset>, and C<$limit> are required parameters.
 444
 445 C<\@sql_params> is an optional list of parameter values to paste in.
 446 The caller is responsible for making sure that C<$sql> has placeholders
 447 and that the number placeholders matches the number of parameters.

 477 #     a WHERE clause (which isn't perfect, but at least should make more cases
