title: how to find "String or binary data would be truncated" error on sql in a big query
body: <p>I have a huge <code>INSERT INTO TABLE1 (....) SELECT .... FROM TABLE2</code> statement. It gives me the error</p>
  
  <blockquote>
    <p>"String or binary data would be truncated".</p>
  </blockquote>
  
  <p>I know that one of the columns from TABLE2 is way bigger for one column from TABLE1 in the <code>INSERT</code> statement. </p>
  
  <p>I have more than 100 columns in each table. So it is hard to find out the problem. Is there any easier way to figure this out?</p>
