I have done this before. Here is the code I ended up using which writes data from a data.table in R to a TABLE in SQL Server 2012 Express:

You need to make use of the RODBC package. You will also need to setup a User DSN ODBC Connection. I called mine "LOCALHOST".


connection <- RODBC::odbcConnect("LOCALHOST")

try(RODBC::sqlDrop(connection, "dbo.iris", errors = FALSE), silent = TRUE)

sqlSave(connection, iris)
