I\'m trying to filter on null columns (I only want to show rows where the column is null), but the issue is I can\'t compare the column to a null, since the column is of DateTim
Doesn't isnull always return a value of the same type as its first parameter?
isnull
Try DateBooked IS NULL instead of Isnull(DateBooked, 'Null Column') = 'Null Column'.
DateBooked IS NULL
Isnull(DateBooked, 'Null Column') = 'Null Column'
