I have some entries where the join date and transaction dates are the same, so I want to include a condition excluding if the count is zero (divide by zero case). I was wondering if I could include it within the COUNT statement.
I’ve tried the below and other slight variations attempting to include a conditional.
Here is a small segment of my code:
SELECT ... d.revenue / COUNT((DATEDIFF(day, c.join_date, d.transaction_dates)) <= 90) ...
As explained above, this is the error:
Invalid operation: Divide by zero

Try to keep this syntax. Your query is incorrect after your first then.
CASE WHEN condition1 THEN result1 WHEN condition2 THEN result2 WHEN conditionN THEN resultN ELSE result END;
