##About

Certain datatypes behave differently when this is enabled.

##Screenshots (Report Designer)

Field "Quantity" compared to field "ExtendedPrice" with alias "Sales"

Provided "Average" is selected, this will generate SQL like the following: CASE WHEN ([dbo].[Invoices].[ExtendedPrice]<AVG(CAST([dbo].[Invoices].[Quantity] AS float))) THEN 1 ELSE 0 END AS 'Sales'
