Although the SQL store has many advantages, it does not support all the predicate constructions that NSPredicate supports. If you search the archives, there have been discussions in the past. [size] is definitely one of those cases. (Also, if your app is garbage collected, you should probably not switch to SQL. See archives again.) -- ____________________________________________________________ Sean McBride, B.
