SAS reads/inserts rows/deletes etc. quite well via ODBC & proc sql.
I've not tried to update existing rows though, but it should be
You have to watch the dates/times as access only has datetime fields.
The documentation in the online help is not as good as it could be.
Main problem when inserting from SAS is that you'd think pass-thru
would work (or at least I did), but access doesn't see the sas data
file that you're running the updates from. Error messages are cryptic,
to say the least. You need to define the Access file via an ODBC
libname statement then write the update SQL as if it's a SAS file that
I've run updates when other users are in the MSAccess system, but
