Gary,
The most generic way to do this is to create a sequence, and then select next('sequencename') and use that to insert into the row

Subject: [GENERAL] unique id's and incr
During the creation of my database, I'm doing a:
CREATE UNIQUE INDEX account_idx ON Accounts (account_id);
to add new rows to my table and keep the id's unique.
During runtime (accessing by JDBC), is there anyway when adding a new row to a table to know the last id entry so as to incr the next one for a new id. I was thinking there might be a way to do this w/o having to query the table for the last id and incr the id before I do another insert.
Any help much appreciated.
