Conditional WHERE clause in SQL Server

Question

I am creating a SQL query in which I need a conditional where clause.

It should be something like this:

SELECT 
    DateAppr,
    Time         


        

Answer 1

Try this one -

WHERE DateDropped = 0
    AND (
        (ISNULL(@JobsOnHold, 0) = 1 AND DateAppr >= 0) 
        OR 
        (ISNULL(@JobsOnHold, 0) != 1 AND DateAppr != 0)
    )
