2018-06-04
| ||
| 08:22 | Add support for window function cume_dist(). Improve tests for percent_rank(). (check-in: 76543f7d user: dan tags: exp-window-functions) | |
|
2018-06-02
| ||
| 21:04 | Add support for window functions row_number(), rank(), dense_rank() and percent_rank(). (check-in: 91c1cb7a user: dan tags: exp-window-functions) | |
|
2018-06-01
| ||
| 21:00 | Allow an entire partition to be cached in a temp table for all types of window frames. This is required by nth_value() and others. (check-in: b5b18f66 user: dan tags: exp-window-functions) | |
|
2018-05-30
| ||
| 20:44 | Allow min() and max() to be used as window functions. (check-in: c16125a8 user: dan tags: exp-window-functions) | |
|
2018-05-28
| ||
| 18:30 | Further window frame tests and fixes. (check-in: e74c6e91 user: dan tags: exp-window-functions) | |
|
2018-05-26
| ||
| 21:17 | More fixes for different window frame types. (check-in: 2c85668a user: dan tags: exp-window-functions) | |
| 12:21 | Minor correction. (check-in: f20d9a99 user: drh tags: rtree-geopoly) | |
|
2018-05-25
| ||
| 22:39 | Untested incremental check-in. Basic infrastructure for geopoly in place, except for the MATCH operator. (check-in: b2745191 user: drh tags: rtree-geopoly) | |
| 20:53 | Incremental check-in: Progress toward implementing the geopoly vtab. (check-in: 9b7d6f98 user: drh tags: rtree-geopoly) | |
| 20:30 | Fix "RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING" window frame processing. (check-in: b4e9c686 user: dan tags: exp-window-functions) | |
| 19:22 | Forward port the geopoly extension functions into the r-tree extension, with the idea of creating a new spatial index based on simply polygons. (check-in: 0593aac8 user: drh tags: rtree-geopoly) | |
| 14:39 | This is an untested proof-of-concept for enhancements to RTree that attempt to use sqlite3_value_nochange() to reduce the amount of work associated with UPDATE operations in cases where either the coordinates or the auxiliary data is unchanged. (Leaf check-in: 6f7cfeff user: drh tags: rtree-update-optimization) | |
| 09:36 | Merge latest trunk changes into this branch. (check-in: 62325198 user: dan tags: exp-window-functions) | |
| 03:46 | Add SQLITE_LOCKED_VTAB and SQLITE_CORRUPT_SEQUENCE to sqlite3ErrName(). Also, use SQLITE_CORRUPT_BKPT in one more place. (Leaf check-in: eac8888d user: mistachkin tags: errCodes) | |

| 23:51 | When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate. This allows one-pass to work on virtual tables that do not allow concurrent reads and writes. Enhance rtree to take advantage of this new capability. (check-in: b816023c user: drh tags: trunk) | |
| 22:42 | New test case for reading and writing the same rtree concurrently. (check-in: 3ba08e53 user: drh tags: trunk) | |
| 22:31 | Do not allow RTree writes when a read cursor is active on the same virtual table, as the writes might rebalance and disrupt the read cursors. Return the new SQLITE_LOCKED_VTAB error code if this happens. (check-in: d4ce6661 user: drh tags: trunk) | |
