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:

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

// Setting up the DataSource object
      com.mysql.jdbc.jdbc2.optional.MysqlDataSource ds 
        = new com.mysql.jdbc.jdbc2.optional.MysqlDataSource();
      ds.setServerName("localhost");
      ds.setPortNumber(3306);
      ds.setDatabaseName("HerongDB");
      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) {
      System.err.println("Exception: "+e.getMessage());
    }
  }
}

The output confirms that JDBC driver mysql-connector-java-5.1.36 is a JDBC 4.0 driver:

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\javac 
   -cp .;\local\lib\mysql-connector-java-5.1.36-bin.jar 
   MySqlDatabaseInfo.java

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\java 
   -cp .;\local\lib\mysql-connector-java-5.1.36-bin.jar 
   MySqlDatabaseInfo

Server name: MySQL
Server version: 5.5.15

   ( Revision: 4fc1f969f740409a4e03750316df2c0e429f3dc8 )
