title: SQL table with a single row?
body: <p>What is the point (if any) in having a table in a database with only one row?</p>
  
  <p>Note: I'm not talking about the possibility of having only one row in a table, but when a developer deliberately makes a table that is intended to always have exactly one row. </p>
  
  <p><strong>Edit:</strong></p>
  
  <p>The sales tax example is a good one.</p>
  
  <p>I've just observed in some code I'm reviewing three different tables that contain three different kinds of certificates (a la SSL), each having exactly one row. I don't understand why this isn't made into one large table; I assume I'm missing something.</p>
