rodbc - Failure to connect to odbc database in R

Question

I've been trying to connect my company's DMS to R using the odbcConnect command, but get the following message:

myConn <-odbcConnect("NZSQL", uid="cejacobson", pwd="password")
Warning messages:
1: In odbcDriverConnect("DSN=NZSQL;UID=cejacobson;PWD=password") :
  [RODBC] ERROR: state IM002, code 0, message [unixODBC][Driver Manager]Data source name not found, and no default driver specified
2: In odbcDriverConnect("DSN=NZSQL;UID=cejacobson;PWD=password") :
  ODBC connection failed

The thing is, I'm positive the Data source name is NZSQL and my uid and password are correct as well. Any insight as to why R may not be finding my data source / driver (the driver is, by the way, specified and working).

Thanks!

Answer 1

I ran across this same problem when I was first trying to connect to an Oracle database. In the end what worked for me was using odbcDriverConnect and a connection string instead of odbcConnect.

myConn <-odbcDriverConnect("Driver={Oracle in OraClient11g_home1};Dbq=NZSQL;Uid=cejacobson;Pwd=password;")

You can check on https://www.connectionstrings.com/ for your specific connection string for your database. Mine happened to be this one.

Hope this helps.
