| 22:30 | [c953715f] part of check-in [997ce6c9] Improvements and simplifications to the equality seek logic. Tests are adjusted so that they all pass now. (check-in: [997ce6c9] user: drh branch: seekeq-experiment, size: 19455) | |

| 13:33 | [f04d5168] part of check-in [54b22192] Standardize the error messages generated by constraint failures to a format of "$TYPE constraint failed: $DETAIL". This involves many changes to the expected output of test cases. (check-in: [54b22192] user: drh branch: omit-rowid, size: 19455) | |
| 01:59 | [1768c1f3] part of check-in [294ed337] Add the conflict2.test script. Fix issues discovered by this script. (check-in: [294ed337] user: drh branch: omit-rowid, size: 19323) | |

| ||
| 21:20 | [031f7265] part of check-in [6f6e2d50] Many spelling fixes in comments. No changes to code. (check-in: [6f6e2d50] user: mistachkin branch: trunk, size: 19311) | |
|
2012-09-27
| ||
| 17:31 | [27adc324] part of check-in [75cda864] Test cases and bug fixes applied to the ORDER BY optimization for joins. Some test cases fail, but except for the new orderby1.test failures, all failures appear to be issues with the tests, not with the core code. (check-in: [75cda864] user: drh branch: qp-enhancements, size: 19311) | |

2012-09-15
| ||
| 18:45 | [d3768229] part of check-in [cfaa7bc1] Attempt to use a covering index even on a full table scan, under the theory that the index will be smaller and require less disk I/O and thus be faster. (check-in: [cfaa7bc1] user: drh branch: fullscan-covering-index, size: 19311) | |
|
2010-04-07
| ||
| 16:54 | [3d3f123f] part of check-in [a811a47f] Wrap all automatic index changes inside SQLITE_OMIT_AUTOMATIC_INDEX. Add the automatic_index PRAGMA to turn it on and off. (check-in: [a811a47f] user: drh branch: experimental, size: 19157) | |
|
2010-04-06
| ||
| 22:33 | [9e685f81] part of check-in [abbf16e5] Veryquick.test is now working. The SQLITE_STMTSTATUS_AUTOINDEX counter added. (check-in: [abbf16e5] user: drh branch: experimental, size: 19149) | |

2008-01-05
| ||
| 17:39 | [45455543] part of check-in [c449e04f] First pass at optimizing max()/min() as described in #2853. Some refinements to come. (CVS 4687) (check-in: [c449e04f] user: danielk1977 branch: trunk, size: 19101) | |
|
2005-04-01
| ||
| 10:47 | [daf498e2] part of check-in [e8391491] Make the ORDER BY clause return equal elements in the same order they were seen (a stable sort). It was returning them in exactly the reverse order. (CVS 2439) (check-in: [e8391491] user: drh branch: trunk, size: 19093) | |
|
2005-01-21
| ||
| 03:12 | [b8668612] part of check-in [bb0254ab] Modify test scripts to work when SQLITE_OMIT_SUBQUERY (along with other OMIT macros) is defined. (CVS 2251) (check-in: [bb0254ab] user: danielk1977 branch: trunk, size: 19101) | |

| 00:11 | [2d6e38e6] part of check-in [e5aa4894] The optimizer now uses only the index and ignores the table if it can get away with doing so, thus saving a single BTree search per row of result. This could potentially double the speed of certain queries. The code passes all regression tests but new tests to exercise the new functionality are yet to be added. (CVS 2170) (check-in: [e5aa4894] user: drh branch: trunk, size: 19014) | |
|
2004-11-22
| ||
| 19:12 | [a7bb41ad] part of check-in [fc8c1393] Add initial infrastructure for cursors. In where.c, optimize out clauses of the form "ORDER BY rowid" if a table scan is being performed. Do a reverse table scan if "ORDER BY rowid DESC" is present. (CVS 2141) (check-in: [fc8c1393] user: drh branch: trunk, size: 19013) | |

2004-11-03
| ||
