| 23:30 | This is another alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed on trunk nearby. In this alternative, covering indexes are simply disabled for WHERE_MULTI_OR on a LEFT JOIN. This might have run-time impact on some obscure queries. This patch is saved for historical reference only. (Closed-Leaf check-in: 668564100e user: drh tags: multi-or-covidx-fix3) | |
| 23:27 | This is an alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed nearby. This one works by having the OP_NullRow opcode create the index if it does not already exist. That is slightly more complex. This patch is saved for historical reference only. (Closed-Leaf check-in: 956bafb69f user: drh tags: multi-or-covidx-fix2) | |
| 23:24 | When an index is used by all branches of the WHERE_MULTI_OR optimization and becomes a covering index, make sure the index has been created prior to NULLing it in the OP_NullRow opcode of a LEFT JOIN. See forum post 0575376e07. The covering-index for WHERE_MULTI_OR optimization was added by [62678be3df35cdcb]. Test cases are in the orindex01.test module of TH3.
