Can we make where clause dynamic?

declare @hourly int

if @hourly = 1
--I want the where clause to say
   TableA.LoadDateTime >= @TodaysDate
if @hourly = 0
--I want the where clause to say
   convert(varchar(8),TableA.LoadDateTime,112) >= convert(varchar(8), @TodaysDate,112)


select col1, col2 from TableA
where TableA.LoadDateTime >= @TodaysDate

To get a dynamic where clause you would need to use dynamic sql and execute that sql string.

Or you could have both queries and an if else statement. Based on the conditions you provide, either one or the other query will be executed.

Will this help...

DECLARE @Hourly INT
SELECT @Hourly = 1
SELECT Col1,Col2 FROM TableA
WHERE
   (CASE WHEN @Hourly = 1 THEN TableA.LoadDateTime
       ELSE CONVERT(VARCHAR(8),TableA.LoadDateTime,112)
   END) >=
   (CASE WHEN @Hourly = 1 THEN @TodaysDate
       ELSE CONVERT(VARCHAR(8),@TodaysDate,112)
   END)
