Creating Connections with DataSource Class

This section describes how to create connection objects with the DataSource class.

It is recommended now that connection objects are created by the DataSource implementation class, com.microsoft.sqlserver.jdbc.SQLServerDataSource. Here is a sample program that creates a connection object using the DataSource class without using JNDI services:

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

// Setting up the DataSource object
      com.microsoft.sqlserver.jdbc.SQLServerDataSource ds
        = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
      ds.setServerName("localhost");
//      ds.setPortNumber(60782);
      ds.setInstanceName("SQLEXPRESS");
      ds.setDatabaseName("AdventureWorks2019");
      ds.setUser("herong");
      ds.setPassword("T0pSecret");

// Getting a connection object
      con = ds.getConnection();

// Database and driver 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());
    }
  }
}

Run the above program with the latest JDK, JDBC driver and SQL Server. The output confirms that mssql-jdbc-9.4.1.jre16.jar supports JDBC API 4.3.

herong> java -cp .;mssql-jdbc-9.4.1.jre16.jar SqlServerDataSource

Server name: Microsoft SQL Server
Server version: 15.00.2000
Driver name: Microsoft JDBC Driver 9.4 for SQL Server
Driver version: 9.4.1.0
JDBC major version: 4
JDBC minor version: 3

Running the same program with other versions of JDBC drivers gives different outputs:

herong> java -cp .:mssql-jdbc-7.4.1.jre12.jar SqlServerDataSource

Server name: Microsoft SQL Server
Server version: 11.00.3128
Driver name: Microsoft JDBC Driver 7.4 for SQL Server
Driver version: 7.4.1.0
JDBC major version: 4
JDBC minor version: 3

herong> java -cp .;sqljdbc42.jar SqlServerDataSource

Server name: Microsoft SQL Server
Server version: 12.00.2000
Driver name: Microsoft JDBC Driver 4.2 for SQL Server
Driver version: 4.2.6225.100
JDBC major version: 4
JDBC minor version: 2
