02:12 | Merge all the latest trunk changes into the sessions branch. (check-in: d69d21903b user: drh tags: sessions) | |
01:55 | Fix a bug (ticket [fc7bd6358f59]) that caused incorrect query results in three way queries that involved comparing INTEGER and TEXT columns for equality. (check-in: 7097241c12 user: drh tags: trunk) | |
2013-02-13
| ||
13:42 | Enhancements to the query planner to make use of indices for ORDER BY even when IN constraints are in the WHERE clause. Add extended error codes for all SQLITE_CONSTRAINT errors. (check-in: 7e14dc734d user: drh tags: sessions) | |
