Calculations on Aggregate Results

Calculations on Aggregate Query Results


 S  M  L  XL  FS  

In this video, I'll show you an easy trick to make complex query calculations simpler by using multiple "nested" queries.

Michael from the UK (Expert Student since 2014) asks: I'm having trouble with calculating the number of years between two dates. In my aggregate query I have a field alias FirstDate set Min and second field alias LastDate. Both are from a field named PaymentDate. I've watched your tutorials and have tried all ways but have been unable to get it to work. It keeps rejecting the field name. Can you help?

BONUS FOR CHANNEL MEMBERS:
Silver Members and up get access to an EXTENDED CUT of this video which covers additional examples. That video will show you how to do the same thing, but with only one query. It's a little more complicated, but if you want to cut down on the number of queries in your database, it's a great solution.
