Hello, I have used your query to calculate age. I am wondering how to sort the newly created AS field. When I am attempting to use a WHERE clause it tells me "Conversion failed when converting the varchar value 'Age' to data type int.
The expression I used is the same formula you provided. At the end of my query I wanted to sort the results using
WHERE 'Age' > 20 ;
and I get "Conversion failed when converting the varchar value 'Age' to data type int.
