| 12:28 | [62bf82ac] part of check-in [b4a9e09e] Refactor the LIKE optimization decision logic so that it uses sqlite3AtoF() on both boundary keys to determine if the optimization can be used when the LHS is something that might not have TEXT affinity. Ticket [ce8717f0885af975]. See also [c94369cae9b561b1], [b043a54c3de54b28], [fd76310a5e843e07], and [158290c0abafde67]. (check-in: [b4a9e09e] user: drh branch: trunk, size: 7957) | |

| 01:41 | [b065d1ca] part of check-in [b043a54c] The "LIKE Optimization" (which converts a LIKE into a BETWEEN operator that is able to use an index) does not work and cannot be used if the collating sequence of the column is not TEXT and if the pattern starts with a "+" sign. This is another case of ticket [c94369cae9b561b1f996d005]. The new test case was discovered by Manuel Rigger. (check-in: [b043a54c] user: drh branch: trunk, size: 7430) | |
