Re: [R] syntax to connect to linked SQL server using RODBC
Hi Varun, Basically when we are pulling data from linked server through SSMS/some other client tools we may need to use query like this format * linkedservername.databasename.schemaname.tablename* and in this case your query like this, table1 <- as.data.table(sqlQuery(dbhandle, 'select * from linkedservername.databasename.schemaname.tablename')) Manu.

Re: [R] syntax to connect to linked SQL server using RODBC
This is not an R concept, and it may be highly specific to the SQL Server API rather than the ODBC API. You might try doing as the Posting Guide recommends and posting in the R-sig-db mailing list. I would also recommend that you figure out from Microsoft documentation what programming API your GUI software example is using to accomplish this rather than referring to that GUI program in your question. -- Sent from my phone.

[R] syntax to connect to linked SQL server using RODBC
Hi All, I would like to know how to connect to a "linked server" from R. I find the linked server under Server Objects > Linked Servers on SQL management studio. Here is the current way I am using to connect to the server: dbhandle <- odbcDriverConnect('driver={SQL Server};server=servername;database=databasename;trusted_connection=true') table1 <- as.data.table(sqlQuery(dbhandle, 'select a, b from table1')) Could you please let me know the syntax to do the same but with the linked server instead? I would like to connect to a database on the linked server and run the query to pull data. Thank you for your help.
