[Serusers] Adding columns to table acc

I am contemplating if I can add two columns to acc: * seq: auto_increment int(11) - to make sure that the chronological order is maintained. This is crucial if you want to debug problems, transfer infor from one table to another, etc. I.e. you really want the INVITE to come before any BYE etc. * status: an enumeration. I am examining the rows in acc an pull out CDR information and I need to flag examined rows. The basic questions is about the programming. It should be safe to add two columns at the end. But if you have any SELECT * somewhere in ser, we have a problem. So, can I add columns to the end of the table acc (or any table?) in database ser without any hick-ups? /hans
