|14:32||The IS operator can now use indexes the same as the == operator. check-in: 3428043c user: drh tags: trunk|
|14:03||A few more test cases for the IS operator. Closed-Leaf check-in: f397c862 user: drh tags: index-is-operator|
|13:41||More test cases. Remove some invalid testcase() macros. Rearrange some code for improved testability. check-in: b3676377 user: drh tags: index-is-operator|
|13:18||Add testcase() macros. Get transitive WHERE clause constraints on IS operators working again. check-in: d195d4a6 user: drh tags: index-is-operator|
|09:53||Merge changes from the index-is-operator branch into this one. Drop the partial support added for IS on this branch by [52e73eec]. check-in: 16ab9caf user: dan tags: ota-update|
|01:05||A new implementation of indexing with the IS operator that works correctly when the IS operator is in the WHERE clause and the operands are from opposite sides of a LEFT JOIN. check-in: 4541688b user: drh tags: index-is-operator|
|19:33||Simplified implementation of indexing with the IS operator. check-in: 95b1f9bf user: drh tags: index-is-operator|
|17:54||Add testcase() macros and comments and a few test-cases. check-in: 24263d08 user: drh tags: index-is-operator|
|15:24||An early attempt to get indexes to work with the IS operator. This code passes tests, but much more testing is needed to verify that it works on all corner cases. check-in: 6f7f1673 user: drh tags: index-is-operator|
|04:50||Enhancements to the MSVC makefile. check-in: 59e3e9e7 user: mistachkin tags: trunk|
