15:33
Fix the build for SQLITE_OMIT_UPSERT (Closed-Leaf check-in: 32956519 user: drh tags: upsert)
01:34
Add new testcase() macros and fix a bug that was revealed when trying to cover all the new test cases. (check-in: 266a99f7 user: drh tags: upsert)
2018-04-17
21:59
Remove unreachable branches. 100% MC/DC in TH3 now. (check-in: 558865d5 user: drh tags: upsert)
20:09
Added a comment on the assert() added to the previous check-in. (check-in: 542547c1 user: drh tags: upsert)
20:06
Fixes to the logic for constraint check reordering during upsert. Improved comments on constraint check bytecode. Add an assert that prevents the same label from being resolved more than once. (check-in: 1ddbb0ff user: drh tags: upsert)
19:29
During PRAGMA vdbe_addoptrace=ON, show calls to sqlite3VdbeResolveLabel() in the debugging output. (check-in: 9ff07a06 user: drh tags: upsert)
18:50
TK_REGISTER expressions nodes are probably not constant. Make sure sqlite3ExprIsConstant() knows this. (check-in: f3d91cad user: drh tags: upsert)
18:18
Simplification to the upsert logic. (check-in: f36d07a5 user: drh tags: upsert)
18:16
Add some more simple test cases for UPSERT. And a minor fix. (check-in: 27cd3b2f user: dan tags: upsert)
16:16
New test cases for upsert. (check-in: 907b5a37 user: drh tags: upsert)
2018-04-16
14:36
Merge the Lemon enhancement from trunk, resulting in smaller parser tables. (check-in: 641f4172 user: drh tags: upsert)
13:26
Remove the MySQL upsert syntax. As an optional alias to the insert table name in order to finish out PostgreSQL upsert syntax emulation. (check-in: 810d9f63 user: drh tags: upsert)
13:00
Add support for the "excluded.*" names in the UPDATE clause of an upsert. (check-in: 0203f34f user: drh tags: upsert)
10:47
Merge changes from trunk. (check-in: 54d96772 user: drh tags: upsert)
2018-04-14
22:35
Get upsert working on WITHOUT ROWID tables. (check-in: d3c53fd3 user: drh tags: upsert)
20:24
Make sure constraint checks occur in the correct order, even in the presence of upserts. (check-in: 07fb30c3 user: drh tags: upsert)
2018-04-13
21:55
First cut at logic to perform DO UPDATE for rowid tables. (check-in: a9080bc8 user: drh tags: upsert)
18:59
Add infrastructure for doing an UPDATE as part of an UPSERT. Still no actual UPDATE code, however. (check-in: 6d3017f9 user: drh tags: upsert)
16:29
Merge the preupdate hook change from trunk. (check-in: 7353caab user: drh tags: upsert)
15:14
Get the ON CONFLICT DO NOTHING form of upsert working by mapping it into INSERT OR IGNORE. (check-in: d07f05e9 user: drh tags: upsert)
14:27
Get the conflict-target clause parsing working correctly, with test cases. This change involves an enhancement to sqlite3ExprCompare() which needs to be reviewed on trunk prior to merging. (check-in: 5bf70425 user: drh tags: upsert)
13:44
Improved conflict-target matching logic. (check-in: 98d32ba6 user: drh tags: upsert)
13:06
Back off of the extended upsert syntax that allows multiple ON CONFLICT clauses. The syntax now is exactly as in PostgreSQL and MySQL. Add support for WHERE clauses on the conflict-target phrase, for partial indexes. (check-in: 2c1b1987 user: drh tags: upsert)
01:15
Begin adding upsert logic. This is an incremental check-in. (check-in: 80969643 user: drh tags: upsert)
2018-04-12
21:42
Break out the upsert code into a separate source file. (check-in: 389806b0 user: drh tags: upsert)
20:21
Fix another typo in a comment. (check-in: 046bb6d2 user: drh tags: upsert)
19:51
Simple comment clarification. No code or logic changes. (check-in: a26f9c9f user: drh tags: upsert)
17:28
Extend the upsert syntax to allow a WHERE clause on the UPDATE. (check-in: e4396c54 user: drh tags: upsert)
15:43
Update the upsert parsing so that it accepts conflict-target labels using the PostgreSQL syntax, and also accepts the MySQL "ON DUPLICATE KEY" syntax. (check-in: c48f64d8 user: drh tags: upsert)
13:15
Add the Upsert object for holding upsert clause information. (check-in: d83eaed5 user: drh tags: upsert)
12:25
Merge changes from trunk. (check-in: 9f6f1180 user: drh tags: upsert)
2018-04-10
00:30
Update the top-level README.md file to point to the whynotget.html document. (check-in: 7dfd4543 user: drh tags: upsert)
2018-04-07
15:04
More complete parsing of UPSERT, including UPSERT within a trigger. The sqlite3Insert() logic to actually perform the UPSERT is not yet implemented, however. (check-in: 5cc2a5a3 user: drh tags: upsert)
2018-04-06
19:36
Demonstration of how the parser can be augmented to recognize a PostgreSQL-style UPSERT. This check-in implements parsing only. (check-in: 9b22905b user: drh tags: upsert)
