>Consider using a character type for your system generated key? I used a system generated key in some tables that is C(4) and stored like (0001, 0002, 0003). I do not have any specific advantages to list in using this format, but I like to use numerics only when necessary. I am also combining the system generated key with a facility ID field and indexing is easier with all character types. Of course, I am assuming that I will never have more than 9999 records for a single facility in this example. Anyway, just some food for thought.


which works faster w/ seeks, char, numeric or integer? i've read about studies on this but can't remember...
