Hi everybody,

really sorry !!!
this is RODBC indeed. But I'm not sure if the package or R version makes a real difference.
In fact, I used fast=FALSE, and I'm now pretty sure the error is due to that parameter.
It may be working far better with fast=TRUE. Gabor, I do not understand how the heck can cats and dogs have interaction with backslashes in SQL queries.

However many thanks !!!
