sum of new columns within a query - sql

Question

I have the below query:
SELECT distinct COUNT(Status) AS [Transactions], sending_organisation AS [Supplier],
DATENAME(mm, Date_Reported) AS Month, DATENAME(yyyy, Date_Reported) AS Year,
Sum(Case When Status = 'Defect' Then 1 Else 0 End) As Defect,
Sum(Case When Status = 'Failed' Then 1 Else 0 End) As Failed,
Sum(Case When Status = 'Success' Then 1 Else 0 End) As Success,
FROM [Tx]
where Channel_Partner = 'CAT'
and DATENAME(yyyy, Date_Reported) = '2018'
and DATENAME(mm, Date_Reported) = 'March'
GROUP BY DATENAME(mm, Date_Reported), DATENAME(yyyy, Date_Reported), sending_organisation
ORDER BY sending_organisation ASC
As you can see I have created the new columns of defect, success, failed.
I wanted to add another column within this same query in finding an aggregated sum of failed + success?
Any ideas how this could done without creating a table or doing more than one query?
thanks in advance

Answer 1

Just add a further column with another COUNT(<expr>):
SUM(CASE WHEN [Status] IN ('Success','Failed') THEN 1 ELSE 0 END) AS SuccessFailed
Further to the OP's comments, (on a totally unrelated matter), to return the data for the current month I would use:
AND Date_Reported >= DATEADD(MONTH, DATEDIFF(MONTH,0,GETDATE()),0)
AND Date_Reportded < DATEADD(MONTH, DATEDIFF(MONTH,0,GETDATE()) + 1,0)
You should be able to alter this slighly for your own needs, if needed. Using something like DATENAME on your column isn't a good idea; it makes the query non-SARGable.
