| 19:51 | Disqualify row-value comparisons for use by an index if the right-hand side has an affinity that does not match the index. Fix for ticket [6ef984af8972c2eb] (check-in: 5c118617cf user: drh tags: trunk) | |
| 11:29 | Previous check-in to fix [b47e3627ecaadbde] was incomplete. This check-in completes the fix and adds a test cases. (check-in: c7da1c01f1 user: drh tags: trunk) | |

| 00:03 | When flipping ("commuting") a comparison operator, set the new EP_Commuted bit rather than adding extra EP_Collate bits, to single later processing that the order of precedence for COLLATE operators is inverted. Fix for ticket [b47e3627ecaadbde] (check-in: 90f7c47735 user: drh tags: trunk) | |
|

| ||

| 15:58 | Enhance the ".imposter" command in the CLI so that the first argument can be an existing WITHOUT ROWID table instead of an index. The resulting imposter is the same table, but with columns in storage order and with all constraints removed. (check-in: 9dc0d34586 user: drh tags: trunk) | |

| ||
| 18:35 | In the Table object, change the nVCol field to nNVCol - the number of non-virtual columns, as that is the quantity that we need most. (check-in: 4ad66af04a user: drh tags: generated-columns) | |
| 18:07 | Bug fix with INSERT using an explicit column list on a table with a non-final STORED column. (check-in: 61b4459ae6 user: drh tags: generated-columns) | |
| 17:54 | Some (but not all) INSERT and UPDATE statements now work for STORED columns. (check-in: fe7517bf4d user: drh tags: generated-columns) | |

| 13:15 | Fix the table_info and table_xinfo pragmas so that they work with virtual columns. Table_info omits virtual columns. Table_xinfo gives them a "hidden" flag of 2, and 3 for STORED columns. (check-in: 069351b85f user: drh tags: generated-columns) | |
|

| 17:46 | Enhancements to SQL query normalization for UPDATE statements. (check-in: bba975c7af user: mistachkin tags: trunk) | |
| 14:56 | If an AFTER DELETE trigger fires when a conflict row is deleted by REPLACE conflict resolution, make sure the conflict really has been resolved and that the trigger did not recreate the row before continuing. Ticket [a8a4847a2d96f5de] (check-in: eea1e7aa57 user: drh tags: trunk) | |
| 12:18 | Initial experimental code for generated column support. Non-functional. (check-in: 11d472c1df user: drh tags: generated-columns) | |

| 17:14 | Futher improvements to LEFT JOIN strength reduction. (check-in: 8a39167bd2 user: drh tags: trunk) | |

| 15:33 | Ensure fts3/4 prefix indexes are flushed to disk before an 'optimize' command. Fix for [745f1abc]. (check-in: 4ed905b188 user: dan tags: trunk) | |
| 14:27 | Fix the fts3/4 integrity-check command so that it works with "ORDER=DESC" tables. Fix for [8a6fa2bb]. (check-in: 5863546df9 user: dan tags: trunk) | |
| 14:25 | Increase the version number to 3.31.0 for the next release cycle. (check-in: ffd4c30620 user: drh tags: trunk) | |

| 16:41 | Fix a problem in the fts3 integrity-check routine causing it to report as corrupt tables that contain values with embedded 0x00 bytes. Ticket [278ac142625e3dcd] (check-in: 629e20c988 user: dan tags: trunk) | |
| 15:17 | Be sure to rewrite column references inside FILTER clauses and window frame definitions when flattening queries. Fix for [1079ad19]. (check-in: ccba7202b6 user: dan tags: trunk) | |
|
2019-10-09
