2017-05-10
19:42
Rename fields of the internal AuxData object to make them unique and easier to search for. (check-in: 2be9850c user: drh tags: trunk)

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)
19:29
Add a single testcase() macro to the subquery processing logic. (check-in: 4e1df76e user: drh tags: trunk)

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)

Minor size and performance improvements to the push-down optimization. (Closed-Leaf check-in: 91dfb61a user: drh tags: pushdown-optimization)

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)

Improved optimizations of views as the right operand of a LEFT JOIN. (check-in: 41c27bc0 user: drh 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)

In the showwal command-line tool, for unix builds, if the auxiliary argument is of the form "Ntruncate" where "N" is a frame number, then truncate the WAL file after the N-th frame. (check-in: 90015df3 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
Make USE_FULLWARN=1 the default for MSVC and fix harmless compiler warnings. (check-in: 6bf67376 user: mistachkin tags: trunk)

Enhance the sqlite3TreeView() display for Expr objects so that it shows the iRightJoinTable value for Expr nodes that have the EP_FromJoin property. (check-in: 5159cb8f user: drh tags: trunk)
12:39
Simplify the interface to the subst() routines that are part of the query flattener by collecting common parameters into the SubstContext object and passing around a pointer to that object. (check-in: e651074b user: drh tags: trunk)

15:36
Update the code in test_delete.c to use the "win32" VFS if SQLITE_OS_WIN is defined. (check-in: fa9bb7b7 user: dan tags: trunk)
13:01
Only use the skip-ahead-distinct optimization if the index has been analyzed and we know that a skip-head is likely to skip over at least 11 rows. The magic number 11 was determined by experimentation. (check-in: 0cf16dec user: drh tags: skip-ahead-distinct)

Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (check-in: 6f54ffd1 user: dan tags: trunk)
01:19
Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. (check-in: 132339a1 user: drh tags: skip-ahead-distinct)
00:12
Fix a regression caused by the fix for ticket [6c9b5514077fed34551f98e64c09a1] - control characters allowed in JSON. (check-in: 8e7b6118 user: drh tags: trunk)
