JDBC Tutorials - Herong's Tutorial Examples - Version 3.00, by Dr. Herong Yang

Specifying Port Number in Connection URL

This section describes how to specify port numbers in the connection URL for a specific SQL Server database instance.

Now I know that my SQLEXPRESS instance is listening on port 60782. I can modify my example program to specify the port number in the connection URL in the following syntax:

jdbc:sqlserver://server_name:port;user=login;password=****

The revised example program below shows you how to include port number 60782 in the connection URL:

/* ConnectionTest3.java

 */
import java.sql.*;
public class ConnectionTest3 {
  public static void main(String [] args) {
    Connection con = null;
    try {

// Obtaining a connection to SQL Server
      con = DriverManager.getConnection(
          "jdbc:sqlserver://localhost:60782;"
        + "user=sa;password=HerongY@ng");

// Connection is ready to use
      DatabaseMetaData meta = con.getMetaData();
      System.out.println("Driver name: "
        + meta.getDriverName());
      System.out.println("Driver version: "
        + meta.getDriverVersion());
      System.out.println("Server name: " 
        + meta.getDatabaseProductName());
      System.out.println("Server version: "
        + meta.getDatabaseProductVersion());
      System.out.println("Connection URL: "
        + meta.getURL());
      System.out.println("Login name: "
        + meta.getUserName());

    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

Compile and run it with JDK 1.8 and JDBC Driver 4.2, you should get:

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\javac ConnectionTest3.java

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\java 
   -cp .;\local\lib\sqljdbc42.jar ConnectionTest3

Driver name: Microsoft JDBC Driver 4.2 for SQL Server
Driver version: 4.2.6225.100
Server name: Microsoft SQL Server
Server version: 12.00.2000
Connection URL: jdbc:sqlserver://localhost:60782;
   authenticationScheme=nativeAuthentication;xopenStates=false;
   sendTimeAsDatetime=true;trustServerCertificate=false;
   sendStringParametersAsUnicode=true;selectMethod=direct;
   responseBuffering=adaptive;packetSize=8000;
   multiSubnetFailover=false;loginTimeout=15;lockTimeout=-1;
   lastUpdateCount=true;encrypt=false;disableStatementPooling=true;
   applicationName=Microsoft JDBC Driver for SQL Server;
   applicationIntent=readwrite;
Login name: sa

Previously, when I ran the same example program with JDK 1.6, JDBC Driver 1.0, and SQL Server 2005 Express Edition, using the correct port number, I got the following output:

C:\herong>\progra~1\java\jdk1.6.0_02\bin\javac ConnectionTest3.java

C:\herong>\progra~1\java\jdk1.6.0_02\bin\java 
   -cp .;\local\lib\sqljdbc.jar  ConnectionTest3

Driver name: Microsoft SQL Server 2005 JDBC Driver
Driver version: 1.0.809.102
Server name: Microsoft SQL Server
Server version: 9.00.1399
Connection URL: jdbc:sqljdbc://
Login name: sa
