| 15:34 | Slight simplification to the query optimizer logic associated with IN (SELECT). (check-in: 2c55c3c295 user: drh tags: trunk) | |
| 15:14 | Add another test case for bug [5e3c8867]. (check-in: d91e57e49f user: dan tags: trunk) | |
| 15:09 | When optimizing expressions of the form "x IN (SELECT ...)" make sure that the subquery is not correlated. Fix for ticket [5e3c886796e5512]. (check-in: 1ed6b06ea3 user: drh tags: trunk) | |
