You can use the read.dbi.ffdf and read.odbc.ffdf function in package
ETLUtils. These allow you to fetch a query directly in an ffdf. See the
examples in their corresponding documentation ?read.dbi.ffdf and
?read.odbc.ffdf or look at this blog post

I am new to R and am encountering memory issues while trying to download a
large table from Green Plump, using sqlQuery. Is there any way this FF
package can help me create a large dataframe in R while downloading from the
server?
The FF documentations are very confusing. Thanks for any help
