Connect R and Teradata using JDBC

Question

I´m trying to connect R and Teradata using RJDBC. I´ve found this link that has an example using mysql, but i´m nos sure how to do the same with teradata. ``` library(RJDBC) drv <- JDBC("com.mysql.jdbc.Driver", "/etc/jdbc/mysql-connector-java-3.1.14-bin.jar", identifier.quote="`") conn <- dbConnect(drv, "jdbc:mysql://localhost/test", "user", "pwd") ``` I´ve downloaded this driver: http://downloads.teradata.com/download/connectivity/jdbc-driver But i´m not sure where i should reference the directory. I know there is a teradataR package out there, but i don´t know if it really works with the R 3.0.0. For the time being i´m just interesting in pulling data out of the database. Something as simple as `SELECT * FROM table`. The problem is RODBC is very slow... Are there other options for doing this task?

Accepted Answer

Using the R Console, enter the following steps below to make a Teradata connection:

```
drv = JDBC("com.teradata.jdbc.TeraDriver","ClasspathForTeradataJDBCDriverFiles") 
```

Example:

```
drv = JDBC("com.teradata.jdbc.TeraDriver","c:\terajdbc\terajdbc4.jar;c:\terajdbc\tdgssconfig.jar")  
```

NOTE: A path on a UNIX machine would use single forward slashes to separate its components and a colon between files.

```
conn = dbConnect(drv,"jdbc:teradata://DatabaseServerName/ParameterName=Value","User","Password") 
```

Example:

```
conn = dbConnect(drv,"jdbc:teradata://jdbc1410ek1.labs.teradata.com/TMODE=ANSI,LOGMECH=LDAP","guestldap","passLDAP01")
```

NOTE: Connection parameters are optional. The first ParameterName is separated from the DatabaseServerName by a forward slash character.

```
dbGetQuery(conn,"SQLquery")
```

Example:

```
dbGetQuery(conn,"select ldap from dbc.sessioninfov where sessionno=session")
```
