  <p>When i am changing the value of i from 0 to 1 then it displays result for 1st row but again it throws exception saying that the index 3 is out of range.
  I have posted the same code and after making the changes (as suggested by the experts on stackoverflow) it gave me a new type of exception. 
  I am putting the link of the previous question-<a href="https://stackoverflow.com/questions/23448861/getting-checked-exception-while-running-a-sql-program">Getting Checked Exception while running a SQL Program</a> and the question was Getting Checked Exception while running a SQL Program</p>
