title: Mysql query where column is white space?
body: <p>This seems like a simple question.  I want to query the MySQL data base where a column is null, "", or white space.  The way I do it now is like this:</p>
  
  <pre><code>select * from table where column_1 is null or REPLACE(column_1," ","") = ""; 
  </code></pre>
  
  <p>Is there a better way to do this?</p>
  
  <p>Thanks!!</p>
