Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. check-in: bdaa6947 user: drh tags: trunk
17:25
Fix a buffer overrun in the previous commit. Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572]. check-in: 299b9570 user: dan tags: query-planner-fix

16:50
Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. check-in: ec5d84ba user: drh tags: query-planner-fix

00:29
A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. check-in: 0ad1ed8e user: drh tags: trunk

Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. check-in: 29ba8128 user: drh tags: trunk
19:16
Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. check-in: 95286821 user: drh tags: trunk
11:04
Rename the internal Schema.flags field to Schema.schemaFlags. check-in: 5ae80b3c user: drh tags: trunk

Improved VdbeCoverage() macros. A few minor simplifications to generated VDBE code. Closed-Leaf check-in: 01f60027 user: drh tags: IN-operator-improvements
2014-08-04
21:26
Part of the change in the previous check-in was incorrect and can result in an incorrect UPDATE for WITHOUT ROWID tables. This check-in fixes the problem. check-in: ee5f6eae user: drh tags: IN-operator-improvements
18:50
Further enhancements to IN-operator processing. check-in: 7fdf26da user: drh tags: IN-operator-improvements

Refinements to the enhanced IN-operator logic. check-in: 92ba2821 user: drh tags: IN-operator-improvements
2014-08-02
21:03
Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. check-in: 436e8842 user: drh tags: IN-operator-improvements

Remove (newly) incorrect preprocessor check to fix build on WinRT. check-in: ba782654 user: mistachkin tags: trunk

A better comment on the generated code for the NULL-in-RHS-of-IN detection logic. check-in: 9bc1c730 user: drh tags: trunk
21:00
Improved detection and handling of NULL values on the RHS of a IN operator. check-in: 468e7300 user: drh tags: trunk
18:00
Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. check-in: c11e55fa user: drh tags: trunk
15:51
Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. check-in: 7c6fbcfe user: drh tags: trunk
15:34
The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. Closed-Leaf check-in: e13175d3 user: drh tags: IN-operator-improvements

Begin making changes to the IN operator in an attempt to make it run faster and to make the code easier to understand. check-in: ee0fd6aa user: drh tags: IN-operator-improvements

Fix a leaked database handle in pager2.test. check-in: 47457b04 user: dan tags: trunk
15:44
Deactivate the DISTINCT in a SELECT on the right-hand side of an IN operator, since it should not make any difference in the output but dues consume extra memory and CPU time. check-in: f4cb5365 user: drh tags: trunk

Re-integrate the recent changes from the 'winMutex' branch back into the Win32 mutex subsystem. check-in: 5360ecb0 user: mistachkin tags: trunk

15:43
Add the "eForce" parameter to the sqlite3_multiplex_shutdown() entry point in test_multiplex.c. Shutdown is forced if true. Shutdown is not done if there are pending database connections and eForce is false, but an error log entry is made instead. check-in: c7303d01 user: drh tags: trunk

In the command-line shell, in CSV output mode, terminate rows with CRNL but do not expand NL characters in data into CRNL.

Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. check-in: 729ece40 user: drh tags: trunk

Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. check-in: 30033f96 user: drh tags: faster-analyze
