Automatically transfer terms from the HAVING clause to the WHERE clause of an aggregate query in cases where the result of evaluating the term depends only one one or more of the GROUP BY expressions (and on no other inputs). check-in: 5375a3ce user: dan tags: having-where-optimization

15:27
Evaluate WHERE clause terms that reference only the index before evaluating terms that require the table, and thereby avoid seeking the table row if index terms are false. This is called the "push-down" optimization in the MySQL world, we are told. check-in: d7bb79ed user: drh tags: trunk

Use sqlite3_table_column_metadata() instead of a SELECT statement to check for the existence of a %_stat table in fts3. This leads to smaller and easier to test code. check-in: dc2a4802 user: dan tags: trunk

Consolidate two branches of code in the "PRAGMA foreign_key_check" implementation. check-in: 69f51f83 user: dan tags: trunk
18:02
Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. check-in: 690870bd user: dan tags: trunk

Add header comment for sqlite3_vtab_collation(). check-in: d238694c user: dan tags: schemalint
14:16
Fix memory leaks in the code on this branch. Make use of the sqlite3_index_constraint.usage field. Do not try to handle ORDER BY terms with explicit COLLATE clauses - they don't get passed to the vtab layer anyway. check-in: 0cd75a87 user: dan tags: schemalint
11:53
In the skip-ahead-distinct optimization, fix a bug in the logic that determines when to invoke the optimization based on sqlite_stat1 statistics. check-in: 89f9e436 user: drh tags: trunk

19:03
Add the TK_IF_NULL_ROW opcode to deal with non-NULL result columns in the result set of a view or subquery on the RHS of a LEFT JOIN that gets flattened. Closed-Leaf check-in: 3a5860d8 user: drh tags: left-join-view
17:30
When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) check-in: f489b5bb user: drh tags: trunk
17:18
An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN. check-in: 1838a59c user: drh tags: left-join-view
14:50
