SQLite does not do this. It makes no effort to keep track of the "degree of distribution" or other statistics associated with indices. It just uses them if they are available. This can be either a feature or a bug, depending on your point of view. I have had people tell me that they prefer the SQLite way. With other databases, they tell me, they are constantly in a struggle trying to outwit and trick the database engine into doing what they want. SQLite just does what you tell it to do, for better or for worse. -- D. Richard Hipp <[EMAIL PROTECTED]>
