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) 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 - newer version
      com.mysql.cj.jdbc.MysqlDataSource ds
        = new com.mysql.cj.jdbc.MysqlDataSource();

// Setting up the DataSource object - older version
      // 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-8.0.19.jar is a JDBC 4.2 driver:

herong> javac -cp .:mysql-connector-java-8.0.19.jar MySqlDatabaseInfo.java

herong> java -cp .:mysql-connector-java-8.0.19.jar MySqlDatabaseInfo
Server name: MySQL
Server version: 8.0.17
Driver name: MySQL Connector/J
Driver version: mysql-connector-java-8.0.19 (Revision: ...)
JDBC major version: 4
JDBC minor version: 2

As a reference, here is the output of the same program using JDK 8 and JDBC driver 5.1.36:

herong> javac -cp .:mysql-connector-java-5.1.36-bin.jar \
   MySqlDatabaseInfo.java

herong> java -cp .:mysql-connector-java-5.1.36-bin.jar MySqlDatabaseInfo
Server name: MySQL
Server version: 5.5.15
Driver name: MySQL Connector Java
Driver version: mysql-connector-java-5.1.36 ( Revision: ... )
JDBC major version: 4
JDBC minor version: 0
