>To be honest, it was my error in this stored procedure, which I just fixed. However, what if NextID table could not be opened or locked? In this case this function still would return 0 and we would end with 0 as Primary Key...
I think my equivalent function returns -1 instead.
In any case, you could have a trigger rule that forbids 0 (or -1) as PK.
