Before I figure it out the hard way, anyone have some pointers on implementing an optimistic lock strategy with iBatis. The difficulty is that we have nothing in the database (or can add anything) like a version field or last update time. The current strategy in the home grown persistance framework (which we will migrate hopefully to ibatis) is to create a hash of the row contents and store it with the value object, then on update reread the row (select for update on primary key) compare the hashes and throw an exception if they don't match. How best to do something similar with iBatis?
