Duplicate ID`s help need

Question

I have an issue where an MEMBER ID is duplicated due to primary status column, I have few rcords which can have status 'P" primary and 'S" for secondary..
I am trying to find all those members who have both statuses , members with either or status.
I have following columns
Memid,Primarystaus,,Line of Business and ServiceArea
I`m trying to find all members who have either 'P' or 'S' Status or any ID`s who have both statuses, How can i see all of this in one resultset?
Any help appreciated

Answer 1

As you've seen, there's more than one way to do this.  Here's another, just the bolded part.
With EXAMPLEDATA as
Select *
From ( Values
(01, 'A', 0101, 010101)
, (02, 'A', 0202, 020202)
, (02, 'P', 0202, 020202)
, (03, 'A', 0303, 030303)
, (03, 'S', 0303, 030303)
, (04, 'P', 0404, 040404)
, (04, 'S', 0404, 040404)
, (05, 'A', 0505, 050505)
, (06, 'A', 0606, 060606)
, (07, 'A', 0707, 070707)
, (08, 'A', 0808, 080808)
, (09, 'P', 0909, 090909)
, (10, 'S', 1010, 101010)
) as VT(Memid, PrimaryStaus, LOB, ServiceArea)
Select Memid
, count(case when PrimaryStaus = 'P' then 'x' else null end) as CtStatusP
, count(case when PrimaryStaus = 'S' then 'x' else null end) as CtStatusS
, Case when count(case when PrimaryStaus = 'P' then 'x' else null end) > 0
and count(case when PrimaryStaus = 'S' then 'x' else null end) > 0 then 'T' else 'F' End InStatusBOTH
From Exampledata
Where PrimaryStaus in ('P', 'S')
Group by MemID
Results:
Memid CtStatusP CtStatusS InStatusBOTH
2 1 0 F
3 0 1 F
4 1 1 T
9 1 0 F
10 0 1 F
The final Case to compute StatusBoth is almost superfluous.  You already have CtStatusP and CtStatusS, so you could skip double-computing it if you wanted.
