Question

I have a query:

select e.Owner as 'Owner', COUNT(l.EnquiryID) as 'Total Sales Lines'
from DayBookQuoteLines l, DayBookEnquiries e
where l.EnquiryID = e.EnquiryID
and MONTH(e.enquirydate) = 8 and YEAR(e.enquirydate) = 2012 
group by e.Owner

This returns the owner column which contains a name and a total column, but i wish to have two more columns where i apply an additional filter and count again, adding in:

l.LostStatusId =2 

and

l.LostStatusId =3 

So i’ll be left with a result set that looks like something like this:

Owner      Total Lines    Total Sold    Total Lost    

Person1    124            112           12

I cant seem to get the query right. I’m attempting to use sub-selects but am obviously missing something, any assistance would be appreciated.

Answer 1

You might conditionally count records by adding one when condition is satisfied.

select e.Owner as 'Owner', 
       COUNT(l.EnquiryID) as 'Total Sales Lines',
       sum(case when l.LostStatusId = 2 then 1 end) TotalSold,
       sum(case when l.LostStatusId = 3 then 1 end) TotalLost
  from DayBookQuoteLines l
 inner join DayBookEnquiries e
    on l.EnquiryID = e.EnquiryID
 where MONTH(e.enquirydate) = 8 
   and YEAR(e.enquirydate) = 2012 
 group by e.Owner
