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:

 * Copyright (c) 2015,, 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();

// 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
    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());

The output confirms that JDBC driver mysql-connector-java-5.1.38 a JDBC 4.0 driver:

C:\herong>javac -cp .;\local\lib\mysql-connector-java-5.1.38-bin.jar

C:\herong>java -cp .;\local\lib\mysql-connector-java-5.1.38-bin.jar

Server name: MySQL
Server version: 5.7.10-log

Driver version: mysql-connector-java-5.1.38 
   ( Revision: fe541c166cec739c74cc727c5da96c1028b4834a )
JDBC major version: 4
JDBC minor version: 0
