| 17:00 | The LIKE optimization does the right thing when collating sequences are present. LIKE expressions where the left-hand side has COLLATE NOCASE are optimized in the default case. (CVS 2637) check-in: ef84ff79 user: drh tags: trunk | |
| 01:38 | Improvements to the formatting and layout of the code in the previous checkin. (CVS 2636) check-in: 73b430de user: drh tags: trunk | |
| 01:34 | Add an assert to verify that floating point values and integers use the same byte order. Add a comment to the SELECT code generator. (CVS 2635) check-in: 07b48921 user: drh tags: trunk | |
