If a DELETE statement has a LIMIT clause, the maximum number of rows that will be deleted is found by evaluating the accompanying expression and casting it to an integer value.

If the DELETE statement has an ORDER BY clause, then all rows that would be deleted in the absence of the LIMIT clause are sorted according to the ORDER BY.
