Adjustments to the WHERE term scanning, to better handle scanning terms of an index. check-in: 5611130a user: drh tags: index-expr
2015-08-26
18:04
Merge enhancements from trunk. check-in: ec6ddb3d user: drh tags: index-expr
14:01
Evaluate expressions only once when the same expression is used in both the result set and in the ORDER BY clause. check-in: c2f3bbad user: drh tags: trunk
11:40
Refactor With.a.zErr into With.a.zCteErr. No logic changes. check-in: 58ba7363 user: drh tags: trunk
11:34
Update the TreeView output for compound SELECT statements so that all entries are shown vertically aligned rather than each successive entry being indented. check-in: 65a89187 user: drh tags: trunk
2015-08-25
19:42
Move sqlite3IndexColumnAffinity() inside of SQLITE_ENABLE_STAT3_OR_STAT4. check-in: b3732a4e user: drh tags: trunk

16:57
Add code to maintain indexes with expression arguments across DELETE, INSERT, and UPDATE statements. Legacy tests pass, but the new code paths are still largely untested. The query planner currently makes no effort to use expression indexes. check-in: efaabdb7 user: drh tags: index-expr
00:34
Fix a memory leak that might occur when compiling with SQLITE_OMIT_CHECK. check-in: 8f1d9f1f user: drh tags: trunk

20:54
Remove some redundant code: Call sqlite3ResolveExprListNames() rather than calling sqlite3ResolveExprNames() in a loop - in two places. check-in: bdaf6646 user: drh tags: trunk
20:21
Enhances the parser so that it accepts arbitrary expressions for the arguments of an index, though the code generator still rejects everything other than simple column names. The sqlite3RestrictColumnListSyntax() routine is removed since that feature is now handled by the parser. check-in: bed42116 user: drh tags: trunk
17:42
Enhance the CREATE VIEW syntax so that the names of columns of the view can be specified after the view name. check-in: d794b34d user: drh tags: trunk

Skip calling the virtual table xDestroy method when it is null. check-in: b73ad305 user: mistachkin tags: trunk

13:54
Virtual table modules with a null xCreate method act as eponymous-only modules - they cannot be used in a CREATE VIRTUAL TABLE statement.

Experimental code (untested) for a JSONB datatype. check-in: e3596ac7 user: drh tags: json

Improve the usage comment on sqlite3_analyzer: show the available switches. check-in: 783f78e3 user: drh tags: trunk
15:29
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS. Also, the URI syntax may be used on the command line to specify the name of the database file to examine, so an alternative VFS may be requested using a URI parameter. check-in: e3c6d4b6 user: dan tags: trunk
15:23
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS.

13:44
Allow a VIEW to reference undefined tables and functions when initially created. The error report is deferred until the VIEW is used. This allows views to be created before subviews and tables that the view references. check-in: 70b57daf user: drh tags: trunk
2015-08-01
18:18
Add extra tests for RBU and FTS3/4. check-in: 34190449 user: dan tags: trunk
