title: SQL Server, where field is int?
body: <p>how can I accomplish:</p>
  
  <pre><code>select * from table where column_value is int
  </code></pre>
  
  <p>I know I can probably inner join to the system tables and type tables but I'm wondering if there's a more elegant way.</p>
  
  <p>Note that column_value is a varchar that "could" have an int, but not necessarily.</p>
  
  <p>Maybe I can just cast it and trap the error?  But again, that seems like a hack.</p>
