Dual & Exists – Useful Functions

    The Dual and Exists functions are useful functions that I often use in my script.  The Dual function allows me to represent a string field numerically, making it ideal for sorting purposes.  The Exists function, used in conjunction with the Where clause, allows me to only load related data into my data model.
