| 17:28 | Add ALWAYS() to an always true conditional that results from the previous check-in. Add a test case for ticket [dbaf8a6820be1ece] to supplement those already checked into TH3. (check-in: aff20980 user: drh tags: trunk) | |

| 17:01 | Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years.

Unexpectedly, in the test case below, a row is fetched that should not be fetched: CREATE TABLE t0(c0 INT UNIQUE); INSERT INTO t0(c0) VALUES (1); SELECT * FROM t0 WHERE '1' IN (t0.c0); -- unexpected: fetches row The WHERE condition should yield FALSE, as demonstrated by the following statement: SELECT '1' IN (t0.c0) FROM t0; -- expected: 0 When removing the UNIQUE constraint on the column, the query works as expected. | ||||
