Group accounts by 1 condition vs 2 conditions - sql

Question

I am trying to get a count of pat_id that were either only "Sent" or only "Sent and Received"
Here is my query so far
select pat_id,
(case when addr_msg_actn_c in(1) then 'Sent' else convert(varchar(10),'Received') end) [Status]
from pat_addr_verif
where pat_id in ('Z1000354','Z1000363','Z1000392','Z1000394')
group by pat_id, addr_msg_actn_c
order by pat_id
Which generates this output
However, I'd like to simplify the output to display like this

Answer 1

Here's a small proof of concept. You can generate a case statement on the sum of a value to choose which text string you want.
CREATE TABLE #SentReceive (
Pat_ID NVARCHAR(8)
,[status] TINYINT
)
INSERT INTO #SentReceive
VALUES ( 'Z1000354' ,1 )
,( 'Z1000354' ,1 )
,( 'Z1000363' ,1 )
,( 'Z1000363' ,2 )
,( 'Z1000392' ,2 )
,( 'Z1000394' ,1 )
,( 'Z1000394' ,2 )
SELECT pat_id
,sentstatus = CASE sum(distinct [status])
WHEN 1
THEN 'Sent'
WHEN 2
THEN 'Received'
WHEN 3
THEN 'Sent and Received'
END
FROM #SentReceive
GROUP BY pat_id
ORDER BY pat_id

Answer 2

create table SentReceive
(
Pat_ID nvarchar(8),
SentOnly nvarchar(8)
)
insert SentReceive
values
('Z1000354','Sent'),
('Z1000363','Sent'),
('Z1000363','Received'),
('Z1000392','Sent'),
('Z1000394','Sent'),
('Z1000394','Received')
select distinct a.Pat_ID,
case
when b.SentOnly is not null then
case a.SentOnly
when 'Received' then b.SentOnly + ' and ' + a.SentOnly
else a.SentOnly + ' and ' + b.SentOnly
end
else a.SentOnly
end as Status
from SentReceive a
left join SentReceive b on a.Pat_ID = b.Pat_ID and a.SentOnly <> b.SentOnly
I did a quickie with only the available data that you provided. If there are other variations in your dataset then you will need to account for that and it may or may not change what I came up with. Good luck!

Answer 3

Here is what I came up with:
;with cte as
(
select 1 as _order, 'Z1000354' as pat_id, 'Sent' as SentOnly
union select 2, 'Z1000363', 'Sent'
union select 3, 'Z1000363', 'Received'
union select 4, 'Z1000392', 'Sent'
union select 5, 'Z1000393', 'Received'
union select 5, 'Z1000394', 'Sent'
union select 6, 'Z1000394', 'Received'
)
select pat_id, replace(_Status,',',' and') as _Status
from(
select distinct pat_id,
STUFF((Select ', '+SentOnly
from cte T2
where T1.pat_id=T2.pat_id
FOR XML PATH('')),1,1,'') as _Status from cte T1
) a
where _Status in (' Sent', ' Sent, Received')

Answer 4

Final query with some help from above posters:
select distinct a.pat_id,
case when b.ADDR_MSG_ACTN_C is not null
then 'Sent and Received' else 'Sent Only' end as Status
from pat_addr_verif a
left join pat_addr_verif b on a.pat_id = b.pat_id and
a.ADDR_MSG_ACTN_C <> b.ADDR_MSG_ACTN_C
where a.pat_id in ('Z1000354','Z1000363','Z1000392','Z1000394')
Correct Final Output
