2022-10-19
| ||
| 11:22 | If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it.

| ||
| 10:41 | In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28) | |

|
2021-07-13
| ||
| 15:30 | Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. This allows the SQL associated with CVE-2020-13871 (ticket [c8d3b9f0a750a529]) to be tested. (Closed-Leaf check-in: d2e67220 user: dan tags: branch-3.28a) | |

| 18:03 | Ensure that a WITHOUT ROWID table does not have the .iPKey field set, even if an OOM error occurs while parsing a schema in PRAGMA writable_schema=ON mode. Add extra assert() statements to triple-check that this never happens. dbsqlfuzz 803bb1f63d6f3bd6c14db568494d6e96be8f1ec9. (check-in: 41228350 user: drh tags: trunk) | |
