Then come back if you have more questions.|||Hi nakata

Welcome to the forum :D

What are you going to do with the table? Index choice depends on this. Given its name I guess a lot of inserts. Many updates? Much querying? Any foreign keys? Any other fields you are likely to link with in any queries?

Are any of the fields likely to always increase in value for each successive record added? (e.g. the transaction_no and transaction_date look like good candidates)|||Damn these slow, clumsy fingers of mine :o And I forgot the phrase "monotonically increasing" :o :o
