Initial implementation of an optimization that attempts to reuse the same materialization of a view on a self-join of the view. check-in: 478c34b9 user: drh tags: materialized-view-reuse
14:09
Add extra tests for the optimization on this branch. check-in: 4921cd95 user: dan tags: having-where-optimization
2017-04-29
20:53
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
18:02
Improvements to opcode documentation in the bytecode engine. No changes to code. check-in: e54c9f8d 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
14:56
Minor size and performance improvements to the push-down optimization. Closed-Leaf check-in: 91dfb61a user: drh tags: pushdown-optimization
2017-04-28
19:59
Within a loop that uses a non-covering index test, test non-indexed terms that can be tested without seeking the main table cursor before those that cannot. check-in: afe68f0a user: dan tags: pushdown-optimization
2017-04-26
17:21

16:04
Fix an FTS5 bug that could cause a prefix-query without a prefix-index on a database that contains delete-markers to return extra, non-matching, rows. check-in: 840042cb user: dan tags: trunk
2017-04-19
13:25
Further improvements to coverage of fts3 module. check-in: 6b21d0fd user: dan tags: trunk
07:33
Further modifications and test cases to improve test coverage of fts3. check-in: ea8a0d2c user: dan tags: trunk
2017-04-18
13:50
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
11:20
Improved optimizations of views as the right operand of a LEFT JOIN. check-in: 41c27bc0 user: drh tags: trunk

Defer checking for null in the comparison operators, since that is an uncommon case. check-in: 56845256 user: drh tags: trunk
20:50
Do not allow a Mem object to be both NULL and some other type at the same time. check-in: e698db19 user: drh tags: trunk
18:42
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
16:07
Further improvements to test coverage in fts3. check-in: 352413ee user: dan tags: trunk

2017-04-16
22:41
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
22:08
Add the anycollseq.c loadable extension in etc/misc check-in: d7b9813c user: drh tags: trunk

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
2017-04-14
22:41
Fix to the decision logic for when to use the skip-ahead-distinct optimization. Closed-Leaf check-in: e50fd489 user: drh tags: skip-ahead-distinct

Remove end-of-line whitespace from lemon.c. check-in: d78355c8 user: drh tags: trunk
19:44
Fix some left-over K&R-C constructs in lemon.c. No changes to the core. check-in: a5379905 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
14:02
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
12:27
Remove an incorrect ALWAYS(). check-in: f956f6ae 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
09:45
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
2017-04-12
17:50
Update fts5 to support "<colset> : ( <expr> )" for column filtering, as well as "<colset> : NEAR(...)" and "<colset> : <phrase>". check-in: c847543f user: dan tags: trunk
17:38
Improved \n and \r escapes in the ext/misc/dbdump.c utility function. The implementation of dbdump.c now matches the implementation in the CLI. check-in: f2643315 user: drh tags: trunk

18:55
Limit the depth of recursion for valid JSON in the JSON1 extension in order to avoid using excess stack space in the recursive descent parser. Fix for ticket [981329adeef51011052667a9]. check-in: 1f68c184 user: drh tags: trunk
18:06
