仅对列中的特定值求和

Question

I have a query in MS Access that display's the following information:

ID	Count	Complete_Type
UserA	10	Replied
UserA	20	Sent
UserA	30	Closed without Response

I want to create a new SQL query that uses the query above but sum's the count's for each unique user only with Completed Type's "Replied" and "Closed without Response". So example, the new query would display this:

ID	Count
UserA	40

Is anyone able to help me write this query?

Answer 1

You can use a where clause:

select id, sum(count)
from t
where Complete_Type in ('Replied', 'Closed without Response')
group by id;
