title: How to set context variable from database
body: <p>I'm trying to set a context variable from a row in a oracle database. I have the table in the database already set up like so:</p>
  
  <pre><code>key     | variable
  name    | BigDecimal
  </code></pre>
  
  <p>I also have created a BigDecimal context variable. How do I link the context variable to the database so it can be used in a SQL query?</p>
