2025-04-10
| ||
| 10:18 | [1ee171d7c3] part of check-in [20acd630b9] Remove unnecessary "www." prefixes on domain names in URLs. (check-in: [20acd630b9] user: drh branch: trunk, size: 32599) | |
|
2023-02-15
| ||
| 17:53 | [b93833890e] part of check-in [5dec3cc022] Do not compute result columns of subqueries that are never used. Make those columns NULL instead. This optimization potentially resolves the enhancement request described by [ticket baa5bb76c35a124c]. (check-in: [5dec3cc022] user: drh branch: omit-unused-subquery-columns, size: 32603) | |
|

|
2021-05-20
| ||

| 00:44 | [8a4f82b104] part of check-in [5614279daf] Replace [0f0959c6f95046e8] with a new and better solution that also fixes the CTE name resolution problem described in forum post 8590e3f6dc. Test cases for both problems added. (check-in: [5614279daf] user: drh branch: trunk, size: 32316) | |
|
2021-03-20
| ||
| 15:11 | [b231edbf0f] part of check-in [50fbd53260] Revise tests cases to align with the new EXPLAIN QUERY PLAN output. (check-in: [50fbd53260] user: drh branch: eqp-improvements, size: 31660) | |
|
2020-10-19
| ||
| 01:23 | [780be387f0] part of check-in [5481fa8c79] Allow multiple recursive terms in the compound SELECT of a recursive CTE. This facilitates writing a query to find find the connected components of an undirected graph. (check-in: [5481fa8c79] user: drh branch: cte-enhancement, size: 31690) | |
|
2020-09-17
| ||
| 00:46 | [323659eaf3] part of check-in [7d2b590d3a] DISTINCT may not be ignored inside a UNION ALL common table expression. Fix for ticket [c51489c3b8f919c5] (check-in: [7d2b590d3a] user: drh branch: trunk, size: 31705) | |
|
2020-01-21
| ||
| 14:42 | [584580a5ae] part of check-in [c7e29458a7] Fix an assert() that could fail in SQLITE_MUTATION_TEST builds following an error in a query that uses CTEs. (check-in: [c7e29458a7] user: dan branch: trunk, size: 30648) | |
|
2020-01-03
| ||
| 02:20 | [386d1c1763] part of check-in [ff9492d3ff] When generating the name of a view (or common table expression) because the SQL does not specify a name, avoid the names "true" and "false" which might be confused for the boolean literals of the same name, leading to an inconsistent abstract syntax tree. (check-in: [ff9492d3ff] user: drh branch: trunk, size: 30456) | |
|
2019-05-23
| ||
| 16:40 | [d32792084d] part of check-in [c1057b2a60] Add test cases for the fix in the previous commit. (check-in: [c1057b2a60] user: dan branch: trunk, size: 29664) | |
|
2019-05-22
| ||
| 22:49 | [f8b59d186a] part of check-in [3cacc4b940] Renumber the Select.selId values in the copies of SELECT statements that implement VIEWs when the VIEW is expanded, so that when the same VIEW is used twice in the same join, each expansion as a distinct selId. This fixes ticket [ce823231949d3abf42453c8]. (check-in: [3cacc4b940] user: drh branch: trunk, size: 29063) | |
|
2019-02-06
| ||

|
2019-01-17
| ||
| 15:40 | [f1fcc3e35e] part of check-in [df08d472b0] Revamp the SrcList allocator routines to be methods of Parse instead of being methods of the "sqlite3" object, so that they can leave better error messages when the SrcList object grows too large. (check-in: [df08d472b0] user: drh branch: trunk, size: 28125) | |
| 14:34 | [ff15177e0e] part of check-in [7cac614d5d] Limit the size of SrcList objects to 200 entries (compile-time configurable using -DSQLITE_MAX_SRCLIST=n). The maximum number of tables in a join has always been 64, so this is not a real constraint on capability. Limiting the size of a SrcList prevents DOS attacks (discovered by OSSFuzz) using crazy nexted CTE joins. (check-in: [7cac614d5d] user: drh branch: trunk, size: 28111) | |
|
2019-01-16

|
2018-12-27
| ||
| 02:16 | [64fcb1a816] part of check-in [202dd03301] Fix a problem in which nested CTEs with the same table name trick the code generator into thinking they are the same CTE, which then tries to use the manifest them both into the same transient table. (check-in: [202dd03301] user: drh branch: trunk, size: 27339) | |
|
2018-09-27
| ||
| 12:14 | [2465d98ffc] part of check-in [7fc2994434] Disallow the use of window functions in the recursive part of a recursive CTE. Fix for ticket [e8275b415a2f03bee]. (check-in: [7fc2994434] user: dan branch: trunk, size: 26670) | |
|
2018-05-03
| ||

| ||
| 18:00 | [6b98f6f2ad] part of check-in [5f0e803e33] Fix test cases so that they work with the new EXPLAIN QUERY PLAN output format. Only some of the cases have been fixed. This is an incremental check-in. (check-in: [5f0e803e33] user: drh branch: rework-EQP, size: 26012) | |

|
2017-05-29
| ||
| 13:09 | [732e3ef398] part of check-in [43c9ae371f] Correctly initialize the iSelectId of FROM clause terms that are a self join of a reused materialized subquery. Without this, the EXPLAIN QUERY PLAN output for the query will identify the subquery using the uninitialized (and arbitrary) iSelectId. (check-in: [43c9ae371f] user: drh branch: trunk, size: 25541) | |
|
2015-12-14
| ||
| 19:42 | [cef099a491] part of check-in [1a24791109] Add a missing memAboutToChange() macro to vdbe.c, the lack of which was causing an assert() to fail incorrectly. Problem found by libfuzzer. (check-in: [1a24791109] user: dan branch: trunk, size: 25196) | |

| ||
| 22:15 | [a1e8660be8] part of check-in [6d2999afbc] Do not allow recursive CTEs that use aggregate queries in the recursive part. (check-in: [6d2999afbc] user: drh branch: trunk, size: 22813) | |
|
2015-05-27
| ||
| 13:06 | [e99845d4f4] part of check-in [0055df0445] CTEs have never had working rowids. So disallow the use of the "rowid" column within CTEs. (check-in: [0055df0445] user: drh branch: no-rowid-in-cte, size: 22592) | |
|
2015-04-12
| ||
| 17:35 | [a86bf7f928] part of check-in [9a453f52a2] Fix a problem with a stale Select.pWith pointer when a CTE is used together with a compound query and an ORDER BY clause. (check-in: [9a453f52a2] user: drh branch: trunk, size: 22374) | |

| 18:12 | [951807f724] part of check-in [61be2da0ae] When resolving names, consider a reference to a recursive CTE column as equivalent to a reference to the outermost name-context.
