Question

Let’s say I have this data in a MSSQL table

type      status       
a         open
b         open
a         closed
a         closed
a         closed
b         open
c         closed

I can run this query to get a table like this
select type,count(*) from table where status = 'open'

a     1
b     2

Then I can do another query
select type,count(*) from table where status = 'closed'

a          2
c          1

How do I write a query that shows me a table like this

type        open         closed
a            1             2
b            2             0
c            0             1

This will produce your desired result

select type,
    SUM(case when status = 'open' then 1 else 0 end) as [Open],
    SUM(case when status = 'closed' then 1 else 0 end) as [Closed]
from table
group by type
