Getting Driver and Server Information

This section describes how to get JDBC driver and database information through the DatabaseMetaData object.

Once you have created a database connection object, you can obtain some version information about the JDBC driver and database server through the DatabaseMetaData object as shown in the following program:

/* OracleDatabaseInfo.java
 - Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
import java.sql.*;
import javax.sql.*;
public class OracleDatabaseInfo {
  public static void main(String [] args) {
    Connection con = null;
    try {

// Setting up the DataSource object
      oracle.jdbc.pool.OracleDataSource ds 
        = new oracle.jdbc.pool.OracleDataSource();
      ds.setDriverType("thin");
      ds.setServerName("localhost");
      ds.setPortNumber(1521);
      ds.setDatabaseName("XE"); // Oracle SID
      ds.setUser("Herong");
      ds.setPassword("TopSecret");

// Getting a connection object
      con = ds.getConnection();
      
// Getting driver and database info
      DatabaseMetaData meta = con.getMetaData();
      System.out.println("Server name: " 
        + meta.getDatabaseProductName());
      System.out.println("Server version: "
        + meta.getDatabaseProductVersion());
      System.out.println("Driver name: "
        + meta.getDriverName());
      System.out.println("Driver version: "
        + meta.getDriverVersion());
      System.out.println("JDBC major version: "
        + meta.getJDBCMajorVersion());
      System.out.println("JDBC minor version: "
        + meta.getJDBCMinorVersion());

// Closing the connection
      con.close();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

The output reports that ojdbc6.jar is a JDBC 11.2 driver, when running with JDK 1.8 and Oracle 11.2 server. But that report is wrong. Oracle has not fixed the problem yet. So I am sure which version of JDBC API ojdbc6.jar supports.

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\javac 
   -cp .;\local\lib\ojdbc6.jar OracleDatabaseInfo.java

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\java 
   -cp .;\local\lib\ojdbc6.jar OracleDatabaseInfo

Server name: Oracle
Server version: Oracle Database 11g Express Edition Release 11.2.0.2.0 
   - Proion   
Driver name: Oracle JDBC driver
Driver version: 11.2.0.4.0
JDBC major version: 11
JDBC minor version: 2

When running with JDK 1.6, Oracle 10.2 and ojdbc14.jar, I was getting similar output:

C:\herong>\Progra~1\java\jdk1.6.0_2\bin\javac 
   -cp .;\local\lib\ojdbc14.jar OracleDatabaseInfo.java

C:\herong>\Progra~1\java\jdk1.6.0_2\bin\java 
   -cp .;\local\lib\ojdbc14.jar OracleDatabaseInfo

Server name: Oracle
Server version: Oracle Database 10g Express Edition Release 10.2.0.1.0 
  - Production
Driver name: Oracle JDBC driver
Driver version: 10.2.0.3.0
JDBC major version: 10
JDBC minor version: 2
