 408 C<$format> and C<$id>. It also returns the C<$total> records available for the

 410 C<$errors> an array ref is returned containing the error after this manner:

 413 C<$error->{'queryerr'}> contains the native db engine error returned for the query.

 437 #
 438 # Where:
 439 #   $sql is the query to modify
 440 #   $new_sql is the resulting query

 442 #       0 if it wasn't otherwise given.
 443 #   $limit is the limit value
 444 #
 445 # Notes:
 446 #   * This makes an effort to not break subqueries that have their own
 447 #     LIMIT specified. It does that by only removing a LIMIT if it comes after
 448 #     a WHERE clause (which isn't perfect, but at least should make more cases
 449 #     work - subqueries with a limit in the WHERE will still break.)
 450 #   * If your query doesn't have a WHERE clause then all LIMITs will be
 451 #     removed. This may break some subqueries, but is hopefully rare enough
 452 #     to not be a big issue.
