| 18:16 | Change the WITH RECURSIVE implementation to use a queue instead of a pair of tables. Add support for ORDER BY, LIMIT, and OFFSET on recursive queries. (check-in: b6cea420 user: drh tags: trunk) | |
| 18:07 | Add support for LIMIT and OFFSET in a recursive query. (Closed-Leaf check-in: 1945484e user: drh tags: cte-via-queue) | |
| 17:43 | Update the spellfix virtual table to optimize queries of the form "SELECT ... FROM tbl WHERE rowid=?". (check-in: a0ba55ff user: dan tags: trunk) | |
| 17:28 | Get ORDER BY working for recursive queries. (check-in: 37b343b0 user: drh tags: cte-via-queue) | |
| 13:35 | Add new SelectDest codes, SRT_Queue and SRT_DistQueue in anticipation of adding ORDER BY support on recursive queries. Factor out the recursive query code generator into a separate procedure. (check-in: 3eb5f9f8 user: drh tags: cte-via-queue) | |
| 10:22 | Fix a typo in a comment. No changes to code or tests. (check-in: cceacc0e user: dan tags: cte-via-queue) | |
| 00:23 | Remove an unnecessary parameter from selectInnerLoop(). Clean up comments. (check-in: 5e6c4a55 user: drh tags: cte-via-queue) | |

| 22:25 | Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. (check-in: b2671e11 user: drh tags: cte-via-queue) | |
| 15:04 | Remove the undocumented requirement for applications that use an SQLITE_ENABLE_SQLLOG build to define a sqlite3_init_sqllog() function. (check-in: 5e43bf01 user: dan tags: trunk) | |
|

| ||
| 19:55 | In where.c, do not allocate space in sqlite3_index_info structures for the internal WHERE clause "terms" generated to record column equivalencies. Fix for ticket [1a1a194d1e5f8]. (check-in: 7d9e2218 user: dan tags: trunk) | |
| 18:25 | Handle a few obscure problems that could manifest if a database corrupted in a certain way was written by a connection in the middle of a SELECT statement on the same db. (check-in: eba8a564 user: dan tags: trunk) | |
| 14:58 | Remove an unused #define and add an assert(), both associated with WITH logic. (check-in: a06235e0 user: drh tags: trunk) | |
| 14:17 | Do not run the tests in with2.test with SQLITE_OMIT_CTE builds. (check-in: 8a973912 user: dan tags: trunk) | |
|
2014-01-18
| ||
| 18:33 | Add a sudoku solver to the recursive query tests in with1.test. (check-in: 679eff87 user: drh tags: trunk) | |
| 15:59 | Add extra test cases. No changes to code. (check-in: d38d485e user: dan tags: trunk) | |
| 15:22 | Add asserts() for a couple of unreachable conditions. Add the Mandelbrot Set query as a test case. (check-in: 2ad4583c user: drh tags: trunk) | |
