title: how to add values in the database
body: <p>In my table I have 5 fields,In those fields,Those are</p>
  
  <pre><code>1.questionId
  2.questionUserId
  3.SurveyId
  4.answer
  5.answerId
  </code></pre>
  
  <p>while I was saving records,I am passing "answer" field and "survey" field as a parameter to my action method.
  My answer parameter is in the form of string separated my semicolumn.I am splitting this one using "semicolumn" and by executing the for loop I am trying to save values into the database.</p>
  
  <p>How I have to save is that,For adding new record,In the for loop all record values are same except "answer" and "answerId" which is auto incrementing.
  while I am saving,For the first time of execution new record is saving but for next iteration,It is throwing <code>DuplicateKeyUnhandledByUserCode</code> and <code>Instance of 'DataModel.question_answer' with identity '1850137295-2-1-2-11' already exists in the cache of the object scope.</code></p>
