RODBC and Very long field lengths
...ng to retrieve a string
from a very long memo field (512*20*9=9360 characters = 74880 bytes) in
an MSAccess database.
It appears that RODBC set a maximum buffer size for a single column of
65535 bytes.

prepared query with RODBC ?
Dear List,
Would anyone know how to perform prepared queries with ROBC ?
I had a shot with some of the internal (non-exported) functions of the package
but ended up with a segfault, so I prefer asking around before
experimenting further...
Thanks,
Laurent
