I am trying to connect R to Teradata and am not sure what the input items are to the RODBC::odbcDriverConnect()
. There is a teradataR package, but it is only used with R versions 3 and under, which I neither have nor want to switch to. Below is a list of the input parameters to get ODBCDriverConnect to work. "Connection" I believe is most important. I need to get an address for a driver that I don't even know if I have. This is what I need most help with. How do I get a driver for Teradata to connect to R? IT at my work is not sure how to do this. Also, if anyone knows of another way to connect Teradata to R (some other package?), please let me know.
connection = ""
case
believeNRows = TRUE
colQuote, tabQuote = colQuote
interpretDot = TRUE
DBMSencoding = "",
rows_at_time = 100
readOnlyOptimize = FALSE
Thank you for your help!
I was able to connect R to Teradata using RODBC package. Here is how to do it if you are working on a pc and have a Teradata driver.
Set up DSN:
A box will pop up that needs to be filled in. The following fields need to be filled:
Name: Can be any name you would like. I chose TeraDataRConnection, for example.
Name or IP address (DBC name or address): Mine for example is: Databasename.companyname.com. I looked to see how Microsoft access was connected to the database and in doing that, found the DBC address.
Username: username that you use to connect to database.
Password: password use to connect to databases (if you don't put your password in here, you will have to manually type it into R every time you connect.
In R:
Download RODBC package
library(RODBC)
ch=odbcConnect("TeraDataRConnection", uid="USERNAME HERE",pwd="PASSWORD HERE")
If you want to confim you are connected, you can type in this code to see the tables:
ListOfTables=sqlTables(ch,tableType="TABLE")
That's it!
