Use the following TSQL template to test your solutions for TSQL Challenge 22

/***********************************************************************

 ---------------------------------------------- 

 Notes:
 1. Copy this template and paste in your SSMS Query editor

 2. Insert your query (solution for TSQL Challenge 22) 
    in the Section between "Insert your query below" 
    and "Insert your query above"

 3. Run the whole batch. If you see 
    "Invalid Results...Failed!" getting printed in output 
    window, there is something wrong in the query.
