java.lang.Objectmondrian.olap4j.MondrianOlap4jDriver
public class MondrianOlap4jDriver
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).
The driver supports the same set of properties as a traditional mondrian
connection. See RolapConnectionProperties
.
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.
