[R] RODBC Multiple Results

[Law, Jason]

Harold,

I have dealt with this problem over the years and after much experimenting, I can say that I *think* what you want is impossible. For RODBC, you need a stored proc that uses SET NOCOUNT ON and that only returns a single result set. You may want to try experimenting with the odbc package (https://github.com/r-dbi/odbc), although there it appears that it isn’t possible there yet, there is a pull request which adds this functionality for sqlServer. You may want to try hitting up the author of the pull request.

Regards,

Jason

A new stored procedure returns multiple tables and I found this on SO indicating that RODBC "may not" be able to retrieve multiple tables.
