Subject:      Re: Generating unique values?

I imagine what you want is something like an AUTOKEY in Ms Access. As far as I know SAS doen't have this. I've always had to use a counter dataset separate to the main table and this counter holds the next available integer id.

I do something like:

data perm.idcount; call symput('nextid',idcount); idcount+1; run;

then use &idcount as your unique value.

Using such a datastep with a counter table prevents the possibility of multiple users getting the same value as the counter table is locked while you get the id and update it.
