Solution to What do I use in Sql to replace a subtraction symbol

Use the DATEDIFF function whose general syntax is

DATEDIFF ( datepart , startdate , enddate )

So for your case the query will be

Select Datediff(day,[Loading Time In],[order time in]) AS [percent of load]


Note that I am finding the difference in days. You can find it in hours, minutes, seconds, years, etc.
