I try to connect to an Oracle database with Mathematica but I get this error:

DBC::classnotfound: oracle.jdbc.driver.OracleDriver"

My code:

 JDBC["oracle.jdbc.driver.OracleDriver", "jdbc:oracle:thin:@ip_server:databasename"], 
 "Name" -> "datbasename", "Username" -> "myusername", "Password" -> "mypassword"]

I tried to use this instruction to connect database:


but this yields the same result.

I can connect to mySQL database but with Oracle databases I have this problem.

    $\begingroup$ You need to specify some additional information, like what Mathematica version you are running, on what OS, what Oracle driver (name, version) you downloaded and where you installed it. $\endgroup$ Commented Dec 16, 2015 at 12:56

You might want to explicitly add the Oracle JDBC jar to the CLASSPATH used by Mathematica.
