title: how to generate Serial numbers +Add 1 in select statement
body: <p>I know we can generate row_number in select statement. But row_number starts from 1, I need to generate from 2 and onwards. </p>
  
  <p>example</p>
  
  <pre><code>party_code
  ----------
  R06048
  R06600
  R06791
  (3 row(s) affected)
  I want it like
  
  party_code serial number
  ---------- -------------
  R06048       2
  R06600       3
  R06791       4 
  </code></pre>
  
  <p>Current I am using below select statement for generate regular row number.</p>
  
  <pre><code> SELECT party_code, ROW_NUMBER() OVER (ORDER BY party_code) AS [serial number]
  FROM myTable
  ORDER BY party_code
  </code></pre>
  
  <p>How can modify above select statement and start from 2?</p>
