SQL Server: Merge Data Rows in single table in output - sql

Question

I have a SQL Server table with the following fields and sample data:
ID Name Address Age
23052-PF Peter Timbuktu 25
23052-D1 Jane Paris 22
23052-D2 David London 24
23050-PF Sam Beijing 22
23051-PF Nancy NYC 26
23051-D1 Carson Cali 22
23056-PF Grace LA 28
23056-D1 Smith Boston 23
23056-D2 Mark Adelaide 26
23056-D3 Hose Mexico 25
23056-D4 Mandy Victoria 24
Each ID with -PF is unique in the table.
Each ID with the -Dx is related to the same ID with the -PF.
Each ID with -PF may have 0 or more IDs with -Dx.
The maximum number of -Dx rows for a given -PF is 9.
i.e. an ID 11111-PF can have 11111-D1, 11111-D2, 11111-D3 up to 11111-D9.
Output expected for above sample data:
ID ID (without suffix) PF_Name PF_Address PF_Age D_Name D_Address D_Age
23052-PF 23052 Peter Timbuktu 25 Jane Paris 22
23052-PF 23052 Peter Timbuktu 25 David London 24
23050-PF 23050 Sam Beijing 22 NULL NULL NULL
23051-PF 23051 Nancy NYC 26 Carson Cali 22
23056-PF 23056 Grace LA 28 Smith Boston 23
23056-PF 23056 Grace LA 28 Mark Adelaide 26
23056-PF 23056 Grace LA 28 Hose Mexico 25
23056-PF 23056 Grace LA 28 Mandy Victoria 24
I need to be able to join the -PF and -Dx as above.
If a -PF has 0 Dx rows, then D_Name, D_Address and D_Age columns in the output should return NULL.
If a -PF has one or more Dx rows, then PF_Name, PF_Address and PF_Age should repeat for each row in the output and D_Name, D_Address and D_Age should contain the values from each related Dx row.
Need to use MSSQL.
Query should not use views or create additional tables.
Thanks for all your help!

Answer 1

select
pf.ID,
pf.IDNum,
pf.Name as PF_Name,
pf.Address as PF_Address,
pf.Age as PF_Age,
dx.Name as D_Name,
dx.Address as D_Address,
dx.Age as D_Age
from
(
select
ID, left(ID, 5) as IDNum, Name, Address, Age
from
mytable
where
right(ID, 3) = '-PF'
) pf
left outer join
(
select
ID, left(ID, 5) as IDNum, Name, Address, Age
from
mytable
where
right(ID, 3) != '-PF'
) dx
on pf.IDNum = dx.IDNum

Answer 2

SELECT t1.ID, LEFT(t1.ID,5) "ID (without Suffix)",
t1.Name "PF_Name", t1.Address "PF_Address", t1.Age "PF_Age",
t2.Name "D_Name", t2.Address "D_Address", t2.Age "D_Age"
FROM PFTable t1
LEFT JOIN PFTable t2 on LEFT(t1.ID,5) = LEFT(t2.ID,5)
WHERE RIGHT(t1.ID,2) = 'PF'
