-- This file implements regression tests for sql library.
--
-- This file implements tests to verify that ticket #1433 has been
-- fixed.  
--
-- The problem in ticket #1433 was that the dependencies on the right-hand
-- side of an IN operator were not being checked correctly.  So in an
-- expression of the form:
--
--         t1.x IN (1,t2.b,3)
--
-- the optimizer was missing the fact that the right-hand side of the IN
-- depended on table t2.  It was checking dependencies based on the
-- Expr.pRight field rather than Expr.pList and Expr.pSelect.  
--
-- Such a bug could be verifed using a less elaborate test case.  But
-- this test case (from the original bug poster) exercises so many different
-- parts of the system all at once, that it seemed like a good one to
-- include in the test suite. 
--
-- NOTE:  Yes, in spite of the name of this file (tkt1443.test) this
-- test is for ticket #1433 not #1443.  I mistyped the name when I was
-- creating the file and I had already checked in the file by the wrong
-- name be the time I noticed the error.  With CVS it is a really hassle
-- to change filenames, so I'll just leave it as is.  No harm done.
