Hi all, I have a large number of clients synchronizing with a central database. The clients update their local data by polling the database for changes at fixed intervals. I need an efficient way of determining if data in a table has been changed (either updated, deleted or inserted). Can this be achieved without scanning the tables using expensive SQL? (my tables are _big_!) Is there some way to get a "time for last update" for a specific table? Or something similar I can use?
Thank you :) Kind regards, Thomas Holmgren Denmark -- Mvh. Thomas Holmgren ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
