Thanks, that's much better. The "http://sqlite.org/draft/expridx.html"; documentation tells all I wanted to know. However, it seems you forgot to link that documentation from "http://sqlite.org/draft/docs.html"; . It should probably be linked from under the heading "SQLite Features and Extensions". There is one apparent inconsistency I was wondering about. For a partial index, the WHERE clause of the index cannot contain functions; whereas for an index on an expression, the expression can contain deterministic functions. What is the explanation of this difference? Is it only historical, because the deterministic functions flag is a new addition? Ambrus
