Beast mode to kill div0 errors
Hi, can anyone tell me why If my "A" code works, and my "B" CASE WHEN... THEN 0 ELSE 2 END code works, why can't I substitute code "A" for "2" in code B? I'm trying to kill divide by zero errors in a beast mode.
A
SUM(IFNULL(`qty sold instock`,0))/SUM(IFNULL(`qty found`,0))
B
(CASE WHEN (IFNULL(`qty found`,0)) = 0 THEN 0 ELSE 2 END)
B ELSE A
(CASE WHEN (IFNULL(`qty found`,0)) = 0 THEN 0 ELSE (SUM(IFNULL(`qty sold instock`,0))/SUM(IFNULL(`qty found`,0))) END)
Thanks

You might need to provide some sample rows of your data. I took your final beast mode:
(CASE WHEN (IFNULL(`qty found`,0)) = 0 THEN 0 ELSE (SUM(IFNULL(`qty sold instock`,0))/SUM(IFNULL(`qty found`,0))) END)
And put together some sample rows with the same columns that look like this and beast mode calc worked.

I thought it should work! There must be some NULL or ZERO scenario I failed to address. This code considering all NULL and ZERO possibilities does work.
CASE
WHEN (SUM(IFNULL(`qty sold instock`,0)) + SUM(IFNULL(`qty found`,0))) = 0 THEN 0
WHEN (SUM(IFNULL(`qty found`,0))) = 0 THEN 0
WHEN (SUM(IFNULL(`qty sold instock`,0))) = 0 THEN 0
ELSE (SUM(`qty sold instock`)*1) / SUM(`qty found`)
END
Thanks!

I found another way to accomplish this with more WHEN statements. Just curious why the B ELSE A does not work.
