Idea for pear sequence tables

I'm sure someone has thought of this and you have a good reason for NOT doing it.. but..I'm curious on why you didn't do it this way? Instead of having another table created for each table I need a sequence on, what about having a sequence table (seq_name, seq_key) with rows for each table and then just fetching and updating that table with the next key? <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> The information in this email and any attachments may contain confidential information that is intended solely for the attention and use of the named addressee(s).
