This looks like using the index to me - or not?
If the index used is the one on SuchName then the LIKE predicate has been transformed into STARTING WITH by the DSQL engine. This will happen automatically with LIKE 'astring%'. But you can make that work unnecessary by using STARTING WITH yourself. >> 3.(Helen) A cursor is much faster than a subquery >Good idea. This looks nice.

That's OK, the original language hasn't been removed. ;-) You would do better to join the correct group for your SQL questions...and to put the release notes in a handy place. If you want everything in one document, there IS a book you can buy.... You're straying further and further away from .NET Provider issues.
