| 21:18 | Much faster implementation of applyNumericAffinity() by avoiding some unnecessary calls to sqlite3Atoi64(). (check-in: c1d8a3f654 user: drh tags: trunk) | |
| 18:33 | Add an assert() as an additional test for fix in check-in [523b42371122d9e1b3]. (check-in: f9e85e6c79 user: drh tags: trunk) | |
| 17:22 | Fix the query flattener optimization so that it preserve the "SF_Compound" bit when flattening a compound subquery into a non-compound outer query. Failure to preserve that bit could allow subsequent flattenings which are not valid. Fix for ticket [c41afac34f15781fe09cd]. (check-in: 523b423711 user: drh tags: trunk) | |
