Class MondrianOlap4jDriver

java.lang.Object
  mondrian.olap4j.MondrianOlap4jDriver

All Implemented Interfaces:

Driver

public class MondrianOlap4jDriver
extends Object
implements Driver

Olap4j driver for Mondrian.

Since olap4j is a superset of JDBC, you register this driver as you would any JDBC driver:

Class.forName("mondrian.olap4j.MondrianOlap4jDriver");

Then create a connection using a URL with the prefix "jdbc:mondrian:". For example,

import java.sql.Connection;
import java.sql.DriverManager;
import org.olap4j.OlapConnection;

Connection connection =
DriverManager.getConnection(
"jdbc:mondrian:Jdbc=jdbc:odbc:MondrianFoodMart; Catalog=file:/mondrian/demo/FoodMart.xml; JdbcDrivers=sun.jdbc.odbc.JdbcOdbcDriver");
OlapConnection olapConnection =
connection.unwrap(OlapConnection.class);

Note how we use the Wrapper.unwrap(Class) method to down-cast the JDBC connection object to the extension OlapConnection object. This method is only available in the JDBC 4.0 (JDK 1.6 onwards).

Connection properties

The driver supports the same set of properties as a traditional mondrian connection. See RolapConnectionProperties.

Catalogs and schemas

Mondrian has a sole catalog, called "LOCALDB". You will get an error if you attempt to use Connection.setCatalog(String) to set it to anything else.
