 413 If passed any query other than a SELECT, or if there is a DB error,
 414 C<$errors> is returned, and is a hashref containing the error after this
 415 manner:
 416
 417 C<$error->{'sqlerr'}> contains the offending SQL keyword.
 418 C<$error->{'queryerr'}> contains the native db engine error returned
 419 for the query.
 420
 421 C<$offset>, and C<$limit> are required parameters.
 422
 423 C<\@sql_params> is an optional list of parameter values to paste in.
 424 The caller is reponsible for making sure that C<$sql> has placeholders
 425 and that the number placeholders matches the number of parameters.

 446 #   $sql is the query to modify

 453 #   * This makes an effort to not break subqueries that have their own
 454 #     LIMIT specified. It does that by only removing a LIMIT if it comes after
 455 #     a WHERE clause (which isn't perfect, but at least should make more cases
 456 #     work - subqueries with a limit in the WHERE will still break.)
 457 #   * If your query doesn't have a WHERE clause then all LIMITs will be
 458 #     removed. This may break some subqueries, but is hopefully rare enough
 459 #     to not be a big issue.
