Question

This is part of a big query.

What I’m trying to do is, if the variable @exemptionStartDate = '1900-01-01', then just select everything,

ie. ce.ExemptionStartDate = ce.ExemptionStartDate.

Otherwise, I only want rows where ce.ExemptionStartDate > @exemptionStartDate

ce.ExemptionStartDate is of DateTime value

SELECT foobar 
WHERE foo = bar
AND ce.ExemptionStartDate = CASE WHEN @exemptionStartDate = '1900-01-01' THEN ce.ExemptionStartDate ELSE (> @exemptionStartDate) END

is it possible? Or will I have to do the hacky thing of making everything a long string, and just adding onto it as necessary?

I’m getting a syntax error, and don’t know how to form such a thing.

Answer 1

not need to complicate matters

if @exemptionStartDate = '1900-01-01'
set @exemptionStartDate = '1753-01-01' --lowest date for datetime

and then it is just

where ce.ExemptionStartDate > @exemptionStartDate
