 470 This function returns a DBI statement handler from which the caller can
 471 fetch the results of the SQL passed via C<$sql>.
 472
 473 If passed any query other than a SELECT, or if there is a DB error,
 474 C<$errors> is returned, and is a hashref containing the error after this
 475 manner:
 476
 477 C<$error->{'sqlerr'}> contains the offending SQL keyword.
 478 C<$error->{'queryerr'}> contains the native db engine error returned
 479 for the query.
 480
 481 C<$offset>, and C<$limit> are required parameters.
 482
 483 C<\@sql_params> is an optional list of parameter values to paste in.
 484 The caller is responsible for making sure that C<$sql> has placeholders
 485 and that the number placeholders matches the number of parameters.
