What if you have 1,000,000 requests/sec? What if between the INSERT and the LAST_INSERT_ID() another INSERT is made?
I use PostgreSQL and with postgres you can always ask the sequence what the next id is going to be. It goes something like this::
next_id = context.GetNextId()[0].next_id context.SQLInsertUser(uid=next_id, name='Peter')
where 'GetNextId' is a ZSQL method that looks like this::
<params></params> SELECT NEXTVAL('users_uid_seq') AS next_id
Its even easier: one ZSQL Method: INSERT INTO foo (foo_id,blah,bar) VALUES (nextval('foo_foo_id_seq'),<dtml-sqlvar blah> ... ); SELECT CURRVAL('foo_foo_id_seq') as foo_id; But your above solution is valid too. Regards Tino
