Add a second field that is auto incremented and change the primary key to that.... So for now you can keep the time-stamp

Thanks for the speedy reply and I have already recommended auto_increment for the solution. We do need that quick fix until the problem is fixed. How would I go about making Mysql wait one second between inserts. We only get about 1000 hits per day, but they tend to be concentrated in short time intervals. > > -- > Keith C.
