Well, maybe: It might reduce the number of cursors somewhat, but if the data (formulae) change in subtle ways, the errors might reoccur, then disappear again, making diagnostics much harder. Not to mention the side effects of this setting on the other SQL that runs in the same session. Sure one can turn it to FORCE and back to EXACT for every statement, but that's two statements too many... Cheers, Flado
