IF Then statement in MS Access Passthrough SQL Query

[Guest]

I am getting a "Division by zero error" in my pass-through query.

Here is my Select statement

SELECT
CD_CODE,(SUM(HP_SYSTEM_EXPECTED_BOOKINGS)/SUM(TOTAL_NET_BOOKINGS))*100 AS
SYSTEMSHARE

The error is because of a zero sum of Total_Net_Bookings.

How can I put a IF statement here to say if Sum(Total_Net_Bookings) = 0,
then SystemShare = 0 else ......

Any ideas?

Give this a try:

IIF(SUM(TOTAL_NET_BOOKINGS)<> 0,
SUM(HP_SYSTEM_EXPECTED_BOOKINGS)/SUM(TOTAL_NET_BOOKINGS),0)

Oops, my bad. I didn't notice that you were referring to a pass through
query. You will probably need to use your server databases equivalent of the
NZ function.

If you work with MSSql then you need to use the case statement
CASE SUM(TOTAL_NET_BOOKINGS)
WHEN NULL THEN 0
ELSE
SUM(HP_SYSTEM_EXPECTED_BOOKINGS)/SUM(TOTAL_NET_BOOKINGS)*100
END AS SYSTEMSHARE
