title: How can I call a stored procedure from Crystal Reports?
body: <p>I have a stored procedure that takes a user ID and calculates their balance with a really simple query and returns it. I want to add this to a crystal report in my application. The only problem is, Crystal Reports wants me to set a value for the procedure, and setting a single value for it would be useless to me.</p>
  
  <p>I have everything grouped by the <code>User.ID</code> field, and I want to use <code>User.ID</code> as the parameter for the query. How can I do this?</p>
