Thanks, I'll try it.
It's really hard to write database independent applications...

So, how can I define that in a MDB schema? Are there any differences in the schema between MDB1 and MDB2 ?Currently primary keys are not supported. However "unique index" are supported, which is more or less the same (the only difference being that usually RDBMS don't allow null's on a primary field while they do on unique fields). Regards, Lukas
