How can I create a trigger that increments on read?
I've got a table with a single row. That row has 1 field. I need to figure out a way to auto increment the vault {in place} every time I read it. So every time a client connects for the data, and does a select it gets a new value.
I'd like to avoid locking if possible, because several machines, with several clients/threads each will be making the queries.
Locks mean they will stack up amd wait, {and in tests back up to the point of a timeout}.
Anyone have any ideas?
