15 check-ins using file src/select.c version f6c73171

2012-12-20
00:32
Remove an unreachable branch operation from the foreign_key_check pragma. (Closed-Leaf check-in: b5a8f316 user: drh tags: foreign-key-check)
2012-12-18
16:07
Resolve names in FROM-clause subqueries prior to resolving names in the result set expressions of a SELECT statement. (check-in: 9b67c633 user: drh tags: trunk)
13:12
Remove old commented-out code from parse.y. Fix some over-length source lines in parse.y. No logical changes. (check-in: 7e30c021 user: drh tags: trunk)
11:59
On atomic-write capable systems, if copying the contents of an in-memory journal to disk fails, close the (on disk) journal file before returning the error to the caller. This causes the subsequent rollback operation to use the in-memory journal. Fix for [df678d738adb]. (check-in: 8183d8d7 user: dan tags: trunk)
2012-12-17
22:32
Added test cases for PRAGMA foreign_key_check. Fixed a bug that appears when the column order of the child and parent differ. (check-in: 25411f83 user: drh tags: foreign-key-check)
20:57
Add to the foreign_key_check pragma an extra output column "parent" that contains the name of the parent table for the constraint that failed. (check-in: 97f7f737 user: drh tags: foreign-key-check)
20:40
Enhance the error message for "foreign key mismatch" to include the names of the child and parent tables. Begin adding test cases for PRAGMA foreign_key_check. Make sure PRAGMA foreign_key_check gets all necessary table locks. (check-in: 0f996352 user: drh tags: foreign-key-check)
18:43
"PRAGMA foreign_key_check" with no argument checks the foreign keys on all tables. (check-in: 57d47423 user: drh tags: foreign-key-check)
18:05
Fix an issue with child keys that are not INTEGER PRIMARY KEY referencing INTEGER PRIMARY KEY in the parent. (check-in: 603b695b user: drh tags: foreign-key-check)
16:46
Prototype for PRAGMA that checks all foreign key constraints on a table. (check-in: 01c980e9 user: drh tags: foreign-key-check)
2012-12-14
17:54
Optimize IN operators in the WHERE clause of queries using virtual tables. (check-in: 3d65c703 user: drh tags: trunk)
17:48
Remove an unreachable branch. Improvements to comments. (Closed-Leaf check-in: d2fb7619 user: drh tags: vtab-IN-opt)
15:54
Merge in all the trunk changes that have occurred since this branch was opened. (check-in: 6d507e4d user: drh tags: vtab-IN-opt)
2012-12-13
18:57
Generalize the min/max optimization so that if an appropriate index exists, the index it can be used by any aggregate query that contains only a single max() or min() and does not contain a GROUP BY clause. (check-in: 52e75594 user: drh tags: trunk)
16:37
Attempt to further generalize the min/max optimization so that, if an appropriate index exists, it can be used by any aggregate query that contains only a single aggregate of the form max(colname) or min(colname) and does not contain a GROUP BY clause. (Closed-Leaf check-in: 7280e14c user: dan tags: minmax-opt)
