2014-01-22
| ||
| 18:31 | Fix harmless compiler warnings. (check-in: dea2ca6a15 user: drh tags: trunk) | |
| 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: b6cea42006 user: drh tags: trunk) | |
| 18:07 | Add support for LIMIT and OFFSET in a recursive query. (Closed-Leaf check-in: 1945484e6b 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: a0ba55ff05 user: dan tags: trunk) | |
| 17:28 | Get ORDER BY working for recursive queries. (check-in: 37b343b018 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: 3eb5f9f8d6 user: drh tags: cte-via-queue) | |
| 10:22 | Fix a typo in a comment. No changes to code or tests. (check-in: cceacc0e79 user: dan tags: cte-via-queue) | |
| 00:23 | Remove an unnecessary parameter from selectInnerLoop(). Clean up comments. (check-in: 5e6c4a55f6 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: b2671e1133 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: 5e43bf0132 user: dan tags: trunk) | |
| 01:13 | Fix a couple comment typos and one overly long line. No functional changes. (Closed-Leaf check-in: c57deced09 user: mistachkin tags: level-pseudocolumn) | |
| 00:19 | Add support for the LEVEL pseudo-column in the recursive part of a common table expression. LEVEL has the value of 1 on the first iteration and successively larger integer values of subsequent iterations. It cannot have a table qualifier. Actual columns named "level" can still be accessed by including the table name qualifier. (check-in: cc1cb32178 user: drh tags: level-pseudocolumn) | |

2014-01-20
| ||
| 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: 7d9e22187d 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: eba8a564e6 user: dan tags: trunk) | |
| 14:58 | Remove an unused #define and add an assert(), both associated with WITH logic. (check-in: a06235e0f6 user: drh tags: trunk) | |
| 14:17 | Do not run the tests in with2.test with SQLITE_OMIT_CTE builds. (check-in: 8a973912e9 user: dan tags: trunk) | |
|
2014-01-18
| ||
| 18:33 | Add a sudoku solver to the recursive query tests in with1.test. (check-in: 679eff8759 user: drh tags: trunk) | |
| 15:59 | Add extra test cases. No changes to code. (check-in: d38d485e58 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: 2ad4583c0c user: drh tags: trunk) | |
| 08:27 | Avoid spurious "no such table" errors in statements of the form "INSERT INTO tbl WITH xxx AS (...) SELECT * FROM xxx". (check-in: cccff8a0b4 user: dan tags: trunk) | |
|
2014-01-17
| ||
| 20:36 | Add extra tests to with2.test. (check-in: eecc325afd user: dan tags: trunk) | |
| 18:34 | Minor simplification of error message text for a couple of errors associated with WITH clause processing. (check-in: 2031004d96 user: drh tags: trunk) | |
| 17:40 | Resolve table names within CTEs in the context in which the CTE is declared, not the context in which it is used. (check-in: a7323838bb user: dan tags: trunk) | |
| 16:19 | Add tests that verify that keywords WITH, WITHOUT, and RECURSIVE can still be used as table and column names. (check-in: 9ca18a0191 user: drh tags: trunk) | |
| 15:27 | Fix a compiler warning in selectPopWith(). (check-in: c8eb11635a user: drh tags: trunk) | |
| 15:15 | Add support for common table expressions (WITH clauses). (check-in: 0171e3bb4f user: dan tags: trunk) | |
| 14:59 | Fix some problems to do with WITH clauses and name resolution. (Closed-Leaf check-in: 6a549187ed user: dan tags: common-table-expr) | |
| 11:48 | Remove some code from resolve.c that was only required for recursive cte references in sub-queries. Also a stray "finish_test" command in pagerfault.test. (check-in: f68c6c4d36 user: dan tags: common-table-expr) | |
|
2014-01-16
| ||
| 22:40 | Add the ability for the authorizer callback to disallow recursive queries. (check-in: 9efc120a15 user: drh tags: common-table-expr) | |
| 21:59 | Tweaks to error message text. (check-in: 090a77d978 user: drh tags: common-table-expr) | |
| 21:02 | Improve the error messages used to report illegal recursive cte references. (check-in: 54eee9fe99 user: dan tags: common-table-expr) | |
| 18:34 | Allow only a single recursive reference in a recursive CTE. Also require that this reference is not part of a sub-query. (check-in: a296b73360 user: dan tags: common-table-expr) | |
| 15:31 | Always use available indices to optimize LIKE operators even if the pattern of the LIKE operator has a COLLATE modifier. This fixes an ineffiency that was introduced into 3.7.15 by check-in [8542e6180d4] on 2012-12-08. (check-in: 16bd54783a user: drh tags: trunk) | |
| 10:58 | Disable the flattening optimization if the parent query is the recursive part of a recursive CTE and the sub-query is a compound query. (check-in: 6bfa387e82 user: dan tags: common-table-expr) | |
| 04:37 | Merge trunk changes. Fix a possible NULL-pointer deference in WITH clause name resolution. (check-in: 7f953b568b user: drh tags: common-table-expr) | |
|
2014-01-15
| ||
| 20:10 | Remove an ALWAYS() that is no longer always true. (check-in: c95823cd45 user: drh tags: common-table-expr) | |
| 19:42 | Fixes so that SQLITE_OMIT_CTE builds work. (check-in: 3908e2ea2e user: dan tags: common-table-expr) | |
| 18:35 | Further comments on WITH-clause processing routines in select.c. (check-in: c948384dfd user: drh tags: common-table-expr) | |
| 18:23 | Add a header comment to the searchWith() routine. (check-in: d9ae0f5d9f user: drh tags: common-table-expr) | |
| 18:21 | Disable automatic indices on recursive CTE references. (check-in: 28aa6db8c8 user: dan tags: common-table-expr) | |
| 18:12 | When resolving names, consider a reference to a recursive CTE column as equivalent to a reference to the outermost name-context. This ensures that correlated sub-queries are correctly identified as such. (check-in: 61be2da0ae user: dan tags: common-table-expr) | |
| 15:27 | Return an error if a CTE specifies a different number of columns than its SELECT statement returns. (check-in: 9a514b50e4 user: dan tags: common-table-expr) | |
| 14:40 | Don't try to verify the schema of transient table (such as generated inside a WITH clause) when generating code for "IN table" operators. (check-in: 860aa93663 user: drh tags: common-table-expr) | |
| 14:17 | Disable the flattening optimization if the sub-query is a recursive CTE. (check-in: 9472f6d820 user: dan tags: common-table-expr) | |
| 02:40 | Use the user-supplied table name in WITH RECURSIVE tables as the internal name of the table and the name of the table in VDBE comments. (check-in: a29330238b user: drh tags: common-table-expr) | |
| 00:24 | Merge recent fixes from trunk. Cherrypick of [c43b59dac1], [a221aa82bb], [e1eba1fb09], and [1e131094b5]. (check-in: c697d2f83c user: mistachkin tags: branch-3.8.2) | |
|
2014-01-14
| ||
| 20:14 | Add code to handle recursive CTEs. (check-in: a5c2a54a07 user: dan tags: common-table-expr) | |
| 10:17 | Fix harmless compiler warning in LEMON. (check-in: f61a70589a user: mistachkin tags: trunk) | |
| 10:17 | For the Win32 VFS, defining winShmMutexHeld should be controlled by NDEBUG, not SQLITE_DEBUG. (check-in: 1e131094b5 user: mistachkin tags: trunk) | |
|
2014-01-13
| ||
| 20:38 | In the command-line shell, defend against a NULL-pointer dereference in the case where sqlite3_column_name() returns NULL (as might happen following an OOM error). (check-in: ac15455abc user: drh tags: trunk) | |
