When we play games with COLLATE in order to commute an operator in the WHERE clause processing, be sure not to use the commuted operator to qualify a partial index, as insufficient COLLATE information is preserved to verify that the expression will correctly qualify the index. Ticket [767a8cbc6d20bd68] check-in: 5351e920 user: drh tags: trunk
2019-09-02
22:13

02:21

00:58
When computing an expression value for an index-on-expression or a CHECK constraint and the expressions uses a REAL table column, but the value of that column is an integer (in other words, when it is using the store-real-as-integer optimization) be sure to promote the value to real before evaluating the expression. Ticket [57af00b6642ecd68]. check-in: 0658c16e user: drh tags: trunk
2019-08-31
20:13

If a DELETE trigger fired by an UPDATE OR REPLACE statement deletes the row being updated, do not attempt to proceed with the original UPDATE operation. Fix for [d6a0fbc1]. check-in: 4145b3e0 user: dan tags: trunk
2019-08-30
23:56
When the affinity of a table column is INT or REAL, make the affinity of corresponding index columns NUMERIC. This increases the precision of index lookups for large numbers so that it matches the precision of ordinary comparison operators. Ticket [40812aea1fde9594] check-in: e0d909c7 user: drh tags: trunk
23:15
Make sure OP_RealAffinity has been applied to all columns of type REAL in the excluded.* pseudo-table of an UPSERT. Ticket [5a3dba8104421320] check-in: 67381dad user: drh tags: trunk

16:46
New test cases for window functions with RANGE BETWEEN and DESC NULLS FIRST. check-in: f7002f86 user: drh tags: trunk

Fix a bug in RANGE window functions that use "ORDER BY <expr> DESC NULLS FIRST" as the window-frame ORDER BY clause. check-in: 39b4cad4 user: dan tags: trunk
16:00
The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] check-in: dd661348 user: drh tags: trunk
15:11
The expression "(X IS FALSE) BETWEEN FALSE AND TRUE" does not implie that X is not NULL. Ticket [fba33c8b1df6a915] check-in: 057fb8b1 user: drh tags: trunk
13:07
The expression "(x IS FALSE) IS FALSE" does not imply that X is not NULL. Ticket [a6408d42b9f44462] check-in: 45ff2b1f user: drh tags: trunk
2019-08-29
21:16

15:50
Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. check-in: 616f5663 user: dan tags: trunk
15:06
Avoid assuming that for "~ (? AND FALSE)" to be true, "?" must not be NULL, just as we do for "NOT (? AND FALSE)". Fix for ticket [c0390363]. check-in: 84ae41fd user: dan tags: trunk
2019-08-27
19:59

17:28
Add ALWAYS() to an always true conditional that results from the previous check-in. Add a test case for ticket [dbaf8a6820be1ece] to supplement those already checked into TH3. check-in: aff20980 user: drh tags: trunk
17:01
Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years. check-in: 7f5168a7 user: drh tags: trunk
10:05
If a TEMP TRIGGER references an auxiliary schema, and that auxiliary schema is detached, move the trigger to reference the TEMP schema before completing the detach, so that the trigger does not hold a dangling schema pointer. Ticket [ac8dd4a32ba4322f] check-in: 069c2f4c user: drh tags: trunk
2019-08-26
20:41

16:38
Fix the likely(), unlikely(), and likelihood() functions so that they have no affinity, just like any other function. Ticket [7e07a3dbf5a8cd26] check-in: 44578865 user: drh tags: trunk
11:11
Fix a false-positive in sqlite3ExprNeedsNoAffinityChange(). Ticket [ac184eb571d5e6e0] check-in: e62eddbb user: drh tags: trunk
