2016-08-20
22:49
The docs promise the in "x BETWEEN y AND z" the x expression is only evaluated once. That is no longer true, and so some tests are failing. This needs to be fixed before merging to trunk. (check-in: e50d264f user: drh tags: rowvalue)
21:11
Further comment enhancements. No changes to code. (check-in: d4562a9e user: drh tags: rowvalue)

00:07
Change the way TK_SELECT_COLUMN is handled so that the subquery is only generated once even if part of the vector comparison is used for indexing and the other part is now. This change also is a pathway to vector assignment in UPDATE statements. (check-in: d8feea7d user: drh tags: rowvalue)
2016-08-19
19:58
Replace the magic number (-2) with its symbol XN_EXPR in the exprMightBeIndexed() routine. No logic changes. (check-in: d4a5af69 user: drh tags: rowvalue)

14:20
Add the capability to VACUUM an attached database by specifying the schema name as an argument to the VACUUM command. Since version 2.0, VACUUM has accepted an argument which was silently ignored. Now it has meaning. (check-in: 29d63059 user: drh tags: vacuum-attached-db)
2016-08-18

2016-08-17

13:34
Increment the version number to 3.15. (check-in: 8c2701e7 user: drh tags: trunk)

2016-08-05
20:54

12:35
Add the experimental SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option. When enabled, the "unknown function" error is suppressed for EXPLAIN and a no-op function named "unknown()" is substituted. This facilitiates using the command-line shell to analyze queries from applications that contain many application-defined functions that are not normally available to the shell. (check-in: b7f30a9f user: drh tags: trunk)
09:09

Enhance the query planner cost estimation for index scans to take into account WHERE clause terms that can be computed using only the index and that do not require looking up rows in the original table.
