title: How to change "LIKE '1%'" so that it is efficient for integers?
body: <p>I want to have query like this :</p>
  
  <pre><code>SELECT TOP 60 lcode
  FROM LessonChart
  WHERE lcode LIKE '1%'
  </code></pre>
  
  <p>But SQL Server says that conversion of int to varchar is not good and keyword "LIKE" is not efficient...</p>
  
  <p>What should I do instead of this code ?</p>
