Remove Window objects from the corresponding Select.pWin list when they are deleted, as they are, for example, when the ORDER BY clause is optimized out. (check-in: f9c6e6a7 user: drh tags: branch-3.28)
2023-10-19
21:05
Ensure that when an ephemeral cursor is reopened with a second invocation of to OP_OpenEphemeral, the sequence counter is reset and the cache marked as stale. Fix for [9cdc5c46]. (check-in: d4bfa8d2 user: drh tags: branch-3.28)
2023-09-15
20:04
Drop support for the view-scan optimization as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: 796a65fa user: drh tags: branch-3.28)

2022-10-19
11:22
If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28)
2022-09-27
17:00
Fix a potential division by zero error in this version of RBU that might occur if an external client checkpoints a wal file created by a suspended RBU process. (Leaf check-in: 73edd93a user: dan tags: branch-3.14)
2022-09-01
10:41
In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28)
2022-08-10
17:03

2021-08-18
19:22
Trying to insert an incorrect datatype into a STRICT table raises an SQLITE_CONSTRAINT_DATATYPE error. Seems to work, though lots more testing is needed. (check-in: a19305e5 user: drh tags: strict-tables)
13:13
What would it be like if you could add the keyword "STRICT" after a CREATE TABLE statement to cause the table to (1) allow only a few well-defined datatypes, (2) rigidly enforce those types, (3) require NOT NULL on PK columns, (4) always enforce foreign key constraint, and so forth? This branch seeks to explore that question. (check-in: 78732b9f user: drh tags: strict-tables)
12:05
Rename the Column.eType field to Column.eCType - with an extra "C". (check-in: b9b0dcd5 user: drh tags: trunk)

18:44
If the special "sqlite_rbu_replace_hack" table is present in an RBU database, use REPLACE instead of INSERT when writing index entries to imposter tables. (check-in: 4b73e151 user: dan tags: rbu-replace-hack)
18:43
During DELETE, if an index entry is missing, do not raise the SQLITE_CORRUPT_INDEX error (added by [f339f31f9e9a856b]) if in "PRAGMA writable_schema=ON" mode. (check-in: 19e56291 user: drh tags: trunk)

11:29
Avoid using LIKE with the target db in RBU. It is possible the user may issue "PRAGMA case_sensitive_like = 1" or override the like() user function, causing RBU to malfunction. (check-in: 7cbd8cd5 user: dan tags: trunk)
2021-08-03

20:09
If a generated column uses the optional keywords GENERATE ALWAYS, try to avoid putting those keywords in the typename of the column. Forum post ff3ffe09251c105b (check-in: 3c954863 user: drh tags: trunk)
18:39
Avoid clownfeet in the names columns when the column names are quoted in the original CREATE TABLE statement. (check-in: 980f7292 user: drh tags: trunk)
12:47
Reduce clownfooting in the allocation of the Table.aCol array. This reduces the amount of heap space required to hold large schemas by about 11%. (check-in: 2941ded0 user: drh tags: trunk)
2021-07-29

16:07
One of the optimizations of check-in [de9c86c9e4cdb34f] does not work for terms originating in the ON/USING clause, as demonstrated by forum post 6cf3bb457c3f4685. This check-in disables that optimization for ON/USING terms. Also improve the TreeView display for the resulting "true"/"false" nodes to show that they originate from the ON/USING clause. Add a testcase() to the other optimization to show that it can still be used for ON/USING terms. (check-in: 1f679604 user: drh tags: trunk)

This is another alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed on trunk nearby. In this alternative, covering indexes are simply disabled for WHERE_MULTI_OR on a LEFT JOIN. This might have run-time impact on some obscure queries.

This is an alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed nearby. This one works by having the OP_NullRow opcode create the index if it does not already exist. That is slightly more complex. This patch is saved for historical reference only. (Closed-Leaf check-in: 956bafb6 user: drh tags: multi-or-covidx-fix2)

When an index is used by all branches of the WHERE_MULTI_OR optimization and becomes a covering index, make sure the index has been created prior to NULLing it in the OP_NullRow opcode of a LEFT JOIN.
