2018-05-05
16:50

19:56
Overhaul of EXPLAIN QUERY PLAN. The output is now in the form of a tree. More details of the query plan are shown, and what is shown is truer to what actually happens. (check-in: ff01bbda user: drh tags: trunk)

03:59
The sqlite3BtreeInsert() routine tries to overwrite an existing cell with modified content if the new content is the same size. Pages are only dirtied if they change. This prototype works some, but still has issues. (check-in: 489451b3 user: drh tags: cell-overwrite-prototype)
01:37
Enhance EXPLAIN QUERY PLAN to report the generation of constant rows using VALUES or just a SELECT without FROM. (check-in: c75eee69 user: drh tags: rework-EQP)

19:32

01:27
Add the "PRAGMA reset_database=ON|OFF" command. When on, it causes the database to appear to be empty, causing the next transaction to reset it to an empty database. (check-in: 02e1a13c user: drh tags: reset-database)
2018-04-27

The previous fix for ticket [d85fffd6ffe856092ed8da] in check-in [0a514e62ad1ebe5c12da8dae] did not completely address the probably in that it only worked for cases where the OP_SCopy that loaded the register was the last instruction in the sequence for the expression, which is not necessarily the case for expressions like CASE...END. This revision prevents the registered that will be recomputed from being cached in the first place. (check-in: 9fd0faf5 user: drh tags: trunk)
17:43
When processing an "ORDER BY ... LIMIT" that does not use an index, check whether or not a record may appear in the final result set before adding it to the temp b-tree used for sorting. (check-in: 0fcfc36c user: dan tags: trunk)
16:13

12:01
Avoid many unnecessary calls to sqlite3ReadSchema() and sqlite3Init() when the schema is known to be valid already. (check-in: 58cf812f user: drh tags: trunk)
10:30

18:53
Fix a problem with processing "LEFT JOIN tbl ON tbl.a = ? AND (tbl.b=? OR tbl.c=?)" in cases where there are indexes on both tbl(a, b) and tbl(a, c). (check-in: ce35e39c user: dan tags: trunk)
17:34
Do not attempt to use terms from the WHERE clause to drive indexes on the right table of a LEFT JOIN. Fix for ticket [4ba5abf65c5b0f9a96a7a40cd18b] (check-in: aeb694e3 user: drh tags: trunk)

13:07
Enhance the CLI to render EXPLAIN QUERY PLAN using an ASCII-art graph. This works with ".eqp" modes and when the query begins with exactly "EXPLAIN QUERY PLAN".

10:57
Fix a memory leak following failure to open an external CSV file in the csv.c extension. (check-in: 526ee07d user: drh tags: trunk)
01:10
In EXPLAIN QUERY PLAN output, do not show an EXECUTE LIST SUBQUERY line for IN operators where the RHS is a list and not a subquery, since in that case there is no SUBQUERY to execute. (check-in: 8bc0207a user: drh tags: trunk)

The ".selecttrace 0x2000" command causes just the top-level parse tree to be displayed, after all transformations, and showing the EQP iSelectId at each level. (check-in: ca34c2dd user: drh tags: trunk)
17:18
The ".selecttrace 4" command now shows only a single parse tree after name resolution. (check-in: 5682146e user: drh tags: trunk)

14:11
A few more tests for upsert. (check-in: b78005b6 user: dan tags: trunk)
13:51
