SQL Rewrite without the NULLIF

Hi EE,

The 3rd party SQL interpreter I am running this script via doesn't like the NULLIF the script works fine when ran within SQL Server directly.

select NULLIF(count(*)*100, 0) as Number from vwReg_RMFeedback_Posted where IncidentInvolved = 'Complaint' 
and (select count(*) from tblDayDates where DayDate between IncidentDate and FBAckDate and DateName(WeekDay,DayDate) not in ('Saturday', 'Sunday')) <= 3
and FBAckDate is not null and Site Like '%Bay%'

Open in new window


Is there a way to rewrite this SQL script without the NULLIF?

Any assistance is welcome.

Thank you.

based on your logic, you can try:

select count(*)*100 as Number 
from vwReg_RMFeedback_Posted 
where IncidentInvolved = 'Complaint' 
and (select count(*) from tblDayDates where DayDate between IncidentDate and FBAckDate and DateName(WeekDay,DayDate) not in ('Saturday', 'Sunday')) <= 3
and FBAckDate is not null and Site Like '%Bay%'

Try changing select to the following, which is effectively the same:

select case when count(*)*100 = 0 then null else count(*)*100 end  as Number

technically that won't return a null for count(*) if there's record(s) returned, so you no need to compare it with case when if it met that condition.
