Connect R to a SQL Server database engine

Question

At my work I have R-Studio (Microsoft R Open 3.2.5) installed and would like to connect to a Microsoft SQL Server database, to run scripts using the tables I have.

Answer 1

Something like this should work:

library(RODBC)
dbconnection <- odbcDriverConnect("Driver=ODBC Driver 11 for SQL Server;Server=YourDBName\\SQLEXPRESS; Database=TestDB;Uid=; Pwd=; trusted_connection=yes")
initdata <- sqlQuery(dbconnection,paste("select * from MyTable;"))
odbcClose(dbconnection)

Finally, make sure SQL Server has all proper permissions applied.
