I'm trying to take an AVG
from one of my columns in MySQL. However, the calculation must be done in another way if some of the values are null
. So, I'm trying to make this:
I want SELECT AVG(amount) from sales
to return NULL
if any row in the sales table has amount
NULL
. Can this be done?
I would try with (it counts nulls as zeros):
SELECT AVG(IFNULL(amount,0)) from sales
Edited (misinterpreted the question before):
SELECT IF(sum(amount is NULL), NULL, AVG(amount)) from sales
