| 18:43 | Fix another problem related to aggregate query LEFT JOIN flattening. (check-in: 8e12c6f5 user: dan tags: trunk) | |
| 15:39 | Add test cases related to fix [e717e029]. (Closed-Leaf check-in: 2909f36b user: dan tags: flatten-left-join) | |
| 15:32 | Make sure IF_NULL_ROW expressions receive a separate slot in the sorter used to implement GROUP BY. (check-in: 2bda4fca user: drh tags: flatten-left-join) | |
| 14:37 | Improved AggInfo.aCol debugging output, intended to debug a problem with LEFT JOIN flattening into an aggregate query with GROUP BY. (check-in: e717e029 user: drh tags: flatten-left-join) | |
| 10:16 | Add a OOM term to a single assert() statement. (check-in: 217fc3eb user: drh tags: trunk) | |

| 16:06 | Fix an error in the aggregate query LEFT JOIN flattening optimization from [2cf373b10c9bc4cb] and further enhance that optimization so that it works even if there is a GROUP BY clause. (check-in: b52393ac user: drh tags: trunk) | |
| 15:54 | Allow subqueries on the right-hand side of a LEFT JOIN to be flattened even if they contain a GROUP BY clause. (Closed-Leaf check-in: 816da9a8 user: drh tags: flatten-left-join) | |
| 14:05 | TK_IF_NULL_ROW expressions must be accumulated in the same way as TK_COLUMN expressions in an aggregate query. Proposed fix for the problem identifyed by dbsqlfuzz 8e17857db2c5a9294c975123ac807156a6559f13. (check-in: 40d08807 user: drh tags: flatten-left-join) | |
| 11:04 | Reduce a timeout in walsetlk.test from 2000ms to 1100ms so that the test runs a bit faster. (check-in: 836fa097 user: dan tags: trunk) | |
|

| ||
| 19:43 | Allow flattening of a subquery that is the right operand of a LEFT JOIN in an aggregate query as long as there is no GROUP BY clause. (The GROUP BY clause will interfere with the operation of the TK_IF_NULL_ROW expression nodes.) (check-in: 2cf373b1 user: drh tags: trunk) | |

| ||
| 22:43 | New test cases for query flattening with LEFT JOIN. (Closed-Leaf check-in: 27f68e47 user: drh tags: flatten-left-join) | |
| 20:56 | Reintroduce flattener constraint (3c), but this time make it apply only if the outer query holds a GROUP BY, not if the outer query is an aggregate. (check-in: 641dfb91 user: drh tags: flatten-left-join) | |
| 15:15 | Add back the ability to flatten a LEFT JOIN subquery - previously removed due to ticket [cad1ab4cb7b0fc344]. (check-in: f8fe936a user: drh tags: flatten-left-join) | |
| 12:36 | Minor correction to a comment. No code changes. (check-in: 5fa00959 user: drh tags: trunk) | |
