- File src/where.c — part of check-in [335863e4d1] at 2007-01-19 01:06:02 on branch trunk — Make sure the IS NULL optimization introduced by check-in (3494) correctly handles a LEFT JOIN where the a term from the right table of the join uses an IS NULL constraint. Ticket #2177. This check-in also adds the new test cases that were suppose to have been added with (3494) but which were mistakenly omitted. (CVS 3595) (user: drh size: 91700)
