∟Getting Driver and Server Information

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) 2005 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
      // For MySQL Connector/J 5.1.38
      // com.mysql.jdbc.jdbc2.optional.MysqlDataSource ds
      //   = new com.mysql.jdbc.jdbc2.optional.MysqlDataSource();

      // For MySQL Connector/J 8.0.17
      com.mysql.cj.jdbc.MysqlDataSource ds
        = new com.mysql.cj.jdbc.MysqlDataSource();
      ds.setServerName("localhost");
      ds.setPortNumber(3306);
      ds.setDatabaseName("test");
      ds.setUser("root");
      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-8.0.17.jar a JDBC 4.2 driver:

herong> java -cp .;\local\lib\mysql-connector-java-8.0.17.jar
   MySqlDatabaseInfo.java

Server name: MySQL
Server version: 8.0.16
Driver name: MySQL Connector/J
Driver version: mysql-connector-java-8.0.17 (Revision: 16a712ddb3...)
JDBC major version: 4
JDBC minor version: 2

Here is output when I ran the test with MySQL Connector/J 5.1.38 and MySQL Server 5.7. It shows that JDBC driver mysql-connector-java-5.1.38-bin.jar is a JDBC 4.0 driver:

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

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

Server name: MySQL
Server version: 5.7.10-log
Driver name: MySQL Connector Java
Driver version: mysql-connector-java-5.1.38
   ( Revision: fe541c166cec739c74cc727c5da96c1028b4834a )
