    String path = System.getProperty("user.dir");
    String createString = "BULK INSERT Assignors FROM  " + path + "\" +filename+ ".txt WITH (FIELDTERMINATOR = ',')";
    try
       {
            // Load the SQLServerDriver class, build the
            // connection string, and get a connection
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            String connectionUrl = "jdbc:sqlserver://arvind-pc\sqlexpress;" +
                                    "database=test01;" +

            Connection con = DriverManager.getConnection(connectionUrl);
            System.out.println("Connected.");

            // Create and execute an SQL statement that returns some data.
            String SQL = "BULK INSERT dbo.Assignor FROM  " + path + "\" +filename+ ".txt WITH (FIELDTERMINATOR = ',')";
            Statement stmt = con.createStatement();
            ResultSet rs = stmt.executeQuery(SQL);

            // Iterate through the data in the result set and display it.
            while (rs.next())
            {
               //System.out.println(rs.getString(1) + " " + rs.getString(2));
                System.out.println(" Going through data");
            }
