| 19:29 | Add a single testcase() macro to the subquery processing logic. (check-in: 4e1df76e user: drh tags: trunk) | |
| 18:02 | Improvements to opcode documentation in the bytecode engine. No changes to code. (check-in: e54c9f8d user: drh tags: trunk) | |
| 15:27 | Evaluate WHERE clause terms that reference only the index before evaluating terms that require the table, and thereby avoid seeking the table row if index terms are false. This is called the "push-down" optimization in the MySQL world, we are told. Do not confuse with WHERE-clause push-down. (check-in: d7bb79ed user: drh tags: trunk) | |
