1   12/12/2010  
2   Null

6   Null

Here I need to find count of null values. ie 2.
I used ISNULL with COUNT function but its not working.
How to find the null values count.
I tried like select count(date) where date is null. but not working.
pls help me out.

Answer 1

count(Null) isn’t supposed to count anything, but you can give the count function something else. For example, 1

select 
count(1) 
where date is null.
