| 13:07 | [15041c7a58] part of check-in [976e39c632] Fix a test case whose value changes under the no_optimization permutation due to the recent change to add the ability for SQLITE_TESTCTRL_OPTIMIZATION to disable one-pass. (check-in: [976e39c632] user: drh branch: trunk, size: 656228) | |

2022-03-03
| ||
| 15:59 | [1c1bf436bf] part of check-in [61a1c6dbd0] Fix for the problem identified in forum post 0cd8e058bf: When evaluating an multi-index OR, do not push down auxiliary WHERE clause terms that involve subqueries into the OR-subqueries. Otherwise, the covering-index optimizer might convert table-references into index-references for the particular OR index that is active for the branch in which the subquery subroutine is coded, and those index-references will not work if the subquery subroutine is invoked from a different OR branch that uses a different index.

2018-12-24
| ||
| 20:21 | [75722434c4] part of check-in [7153552bac] Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide a subquery number that is related back to the .selecttrace output. (check-in: [7153552bac] user: drh branch: reuse-subqueries, size: 654863) | |

| ||
| 22:02 | [5c566388f0] part of check-in [0dc4cb9355] Candidate fix for the optimizer problem described in ticket [b7c8682cc17f3] which can causes a LEFT JOIN to be changed into a INNER JOIN if there are OR terms in the WHERE clause. (check-in: [0dc4cb9355] user: drh branch: trunk, size: 654507) | |

|
2010-11-13
| ||
| 16:42 | [aa4cfcd6f6] part of check-in [6611b76b02] Change the EXPLAIN QUERY PLAN output to use "USING INDEX" instead of "BY INDEX", and to use "SEARCH" instead of "SCAN" for loops that are not full-table scans. (check-in: [6611b76b02] user: dan branch: experimental, size: 654564) | |
