Data show by list when group by is not include data - sql

Question

I have a sql command like this
select mainPOID.EstAPDate,mainPOID.POID,TTm.ID,TTMAmount=TTMD.InvoiceAmount
From TTBeforeMms TTM
inner join TTBeforeMms_Detail TTMD on TTM.ID = TTMD.ID
inner join (
select distinct main.EstAPDate,main_D.POID
From AP main
left join AP_Detail main_D on main.ID = main_D.ID
where main.Type ='PA' and main.EstAPDate between '2018/6/01' AND '2018/6/15' and left(main_D.InvoiceNo,4) != '1111' ) mainPOID on TTMD.poid =mainPOID.POID and TTM.EstAPdate<=mainPOID.EstAPdate and mainPOID.POID='CM3PU18030009'
order by mainPOID.EstAPDate,mainPOID.POID
sql result will like this
My question is
How can Data show by list when group by is not include data?
For example
ID will show by list When I group by EstAPDate、POID and sum(TTMAmount)

Answer 1

You can store in one temp table or use CTE
CREATE TABLE [dbo].#Columnss(
espapdate date ,
poid varchar(max),
id varchar(max),amount decimal(22,6))
GO
insert into #Columnss values('2018-06-15','cm3','pt20',19988.8900)
insert into #Columnss values('2018-06-15','cm3','pt21',265.8900)
SELECT
REPLACE(ESPAPDATE,'-','/') ESPAPDATE, POID,
STUFF(
(SELECT ' , ' + OD.ID
FROM #COLUMNSS OD
WHERE OD.ESPAPDATE = O.ESPAPDATE
AND OD.POID = O.POID
FOR XML PATH('')), 1, 2, ''
) PRODUCTNAMES,SUM(AMOUNT)AMOUNT
FROM #COLUMNSS O
GROUP BY ESPAPDATE, POID
output
espapdate poid ProductNames amount
2018/06/15 cm3 pt20 , pt21 20254.780000

Answer 2

there are lots of CSV example using FOR XML PATH. For your case here, i am wrapping your existing query in a CTE and then from there generate the CSV string for ID
; with
cte as
(
select mainPOID.EstAPDate, mainPOID.POID, TTm.ID, TTMAmount=TTMD.InvoiceAmount
From TTBeforeMms TTM
inner join TTBeforeMms_Detail TTMD on TTM.ID = TTMD.ID
inner join (
select distinct main.EstAPDate,main_D.POID
From AP main
left join AP_Detail main_D on main.ID = main_D.ID
where main.Type ='PA'
and main.EstAPDate between '2018/6/01' AND '2018/6/15'
and left(main_D.InvoiceNo,4) != '1111'
) mainPOID on TTMD.poid = mainPOID.POID
and TTM.EstAPdate <= mainPOID.EstAPdate
and mainPOID.POID = 'CM3PU18030009'
)
SELECT EstAPDate, POID,
ID = STUFF(c.ID, 1, 1, ''),
TTMAmount = SUM(TTMAmount)
FROM cte
CROSS APPLY
(
SELECT ',' + ID
FROM cte x
WHERE x.EstAPDate = cte.EstAPDate
AND x.POID = cte.POID
FOR XML PATH ('')
) c (ID)
GROUP BY EstAPDate, POID
ORDER BY EstAPDate, POID
