Key and timestamp ( That if i'm not worng works only for Sql Sever) Not wrong, but some-time peoples can use this method and in Firebird too... for example if on timestamp field creates trigger... in this case it's will work as AllFields, with that difference that request will have a more good plan for execution. :) > > The fourth variant -- WHERE is generated on primary key fields > > > and > field with fixed-name (for example "TIMESTAMP" or > > "LAST_MODIFIED"). > As i don't like fixed things ;) if i do this i will add a property > for this ( aand provide a default value for it, of course ) I'm don't like fixed things too... but TIMESTAMP fields can be more than 1, and may be selects this uniquely impossible.
