Hi all, I think most of us has seen someone trying to be smart or trying to gain database independencies by not using oracle sequence but instead roll their own system by using a table, and a row for each "sequence". Almost every attempt on this I yet have seen has been plagued with row lock contention or other concurrencies, scalability zero... Have anyone actually seen some implementation of this kind work when load increase? /johan -- //www.freelists.org/webpage/oracle-l
