14:27
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.

2019-09-02

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: 0658c16e31 user: drh tags: trunk
2019-09-01

2019-08-30

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: e0d909c740 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: 67381daded user: drh tags: trunk

The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] check-in: dd66134817 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: 057fb8b180 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: 45ff2b1f26 user: drh tags: trunk

Remove an unreachable branch in the NULLS LAST logic of RANGE window functions. check-in: 47cd634c98 user: drh tags: trunk
15:50
Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. check-in: 616f5663b3 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: 84ae41fd2f user: dan tags: trunk
14:25
