Hi Ed,

>That's my general understanding, but a view isn't really a table, either, so I don't know what's happening here. The problem may arise from forming the CDX based on the alias rather than on the underlying table name, or there may be a difference in the header of a view. I'm guessing at this point, as I pointed out in the preceding message.

At least my basic understanding was right (or at least consistent (sp?) with yours <G>)). It is a rare error, but my application logs everything open at the time. Maybe a pattern will show up. Would you like me to let you know if I squash it?
