title: How to search for rows containing a substring?
body: <p>If I store an HTML TEXTAREA in my ODBC database each time the user submits a form, what's the <code>SELECT</code> statement to retrieve 1) all rows which contain a given sub-string 2) all rows which don't (and is the search case sensitive?)</p>

  <p>Edit:  if <code>LIKE "%SUBSTRING%"</code> is going to be slow, would it be better to get everything &amp; sort it out in PHP?</p>
