If a column has `collate nocase`, SQLDIFF utility fails to report any differences. Database a.db: ``` CREATE TABLE t(s collate nocase); INSERT INTO t VALUES('sample'); ``` and database b.db: ``` CREATE TABLE t(s collate nocase); INSERT INTO t VALUES('SAMPLE'); ``` Now, use `SQLDIFF a.db b.db` and you won't see any differences. This is because of the `collate nocase` as when you remove it, the difference is shown. I don't know if this is intentional behavior but to me it appears wrong. I expect a difference tool to show true differences between two databases. The use of `collate nocase` may be used for case-insensitive retrieval but if the actual contents are different, a difference tool should report that.
