Re: SQL GROUP BY and COUNT

COALESCE perhaps?

I have an SQL view which is a right join where the left table has
722 rows and the right table has 854 rows. I therefore expect 132 null
rows to represent the left table. Yet, when I run the following SQL
statement it only counts 722 rows. Why doesn't it count the 132 null
rows? And is there a way I can change this statement to count those rows
along with the other rows? Thanks.

Select LifoYn, count(LifoYn) as Count
from SHR460T.IMLFCMPV02
Group by LifoYn
Order by LifoYn;

LIFOYN COUNT
N 229
Y 493
- 0
------ -------
722
- 854

132
