| 13:26 | Convert expressions of the form "X IN (?)" with exactly one value on the RHS of the IN into equality tests: "X=?". Add test cases to verify that statements work correctly on this corner case. Fix for ticket [e39d032577df6942]. check-in: e68b427a user: drh tags: trunk | |
| 12:36 | One possible fix for the [e39d032577d] problem it to replace the failing assert() with a testcase() as shown here. Closed-Leaf check-in: eae6dfbe user: drh tags: tkt-e39d0325 | |
