How to combine two FOR XML AUTO into 1 XML? - sql-server

Question

We are using SQL Server 2012.
Table myTbl has a one to many relationship to table myAllocation
Table ABC_myTbl has a one to many relationship to table ABC_myAllocation
The below query combined 2 FOR XML AUTO into 1 XML, but the problem is ID, SystemSource, Manager are included in element TradeTicket instead of on their own, and accountManager, unitPrice are included in element allocationRow instead of on their own.
Thank you
SELECT '<?xml version="1.0"?>'+
(SELECT
( SELECT trTicket.[id],trTicket.[manager],'PFM' as SystemSource
,allocationRow.accountNumber,allocationRow.unitPrice
FROM myTbl AS trTicket
LEFT JOIN myAllocation AS allocationRow ON allocationRow.trade_ticket_id=trTicket.id
WHERE trTicket.ID = 8779631
ORDER BY trTicket.id,allocationRow.AccountNumber
FOR XML AUTO, type)
,
(
SELECT trTicket.[id],trTicket.[manager],'CRD' as SystemSource
,allocationRow.accountNumber,allocationRow.unitPrice
FROM ABC_myTbl AS trTicket
LEFT JOIN ABC_myAllocation AS allocationRow ON allocationRow.trade_ticket_id=trTicket.id
WHERE trTicket.ID = 8
ORDER BY trTicket.id,allocationRow.AccountNumber
FOR XML AUTO, type)
FOR XML PATH('trTickets'), ELEMENTS) AS XMLResult
This is the current result:
<?xml version="1.0"?>
<trTickets>
<trTicket id="8779631" SystemSource="PFM" manager="MCM">
<allocationRow accountNumber="292 " unit_Price="300"/>
</trTicket>
<trTicket id="8" SystemSource="CRD" manager="DOYLE">
<allocationRow unitPrice="100" accountNumber="F11 "/>
<allocationRow unitPrice="200" accountNumber="F22 "/>
</trTicket>
</trTickets>
This is the desired result that I am looking for:
<?xml version="1.0"?>
<trTickets>
<trTicket>
<id>8</id>
<manager>DOYLE</manager>
<SystemSource>CRD</SystemSource>
<allocationRow>
<accountNumber>F11</accountNumber>
<unitPrice>100</unitPrice>
</allocationRow>
<allocationRow>
<accountNumber>F22</accountNumber>
<unitPrice>200</unitPrice>
</allocationRow>
</trTicket>
<trTicket>
<id>8779631</id>
<manager>MCM</manager>
<SystemSource>PFM</SystemSource>
<allocationRow>
<accountNumber>292</accountNumber>
<unitPrice>300</unitPrice>
</allocationRow>
</trTicket>
</trTickets>
Data sample:
Table ABC_myTbl:
ID Manager
-----------
8 DOYLE
Table ABC_myAllocation:
accountNumber unitPrice
-------------------------
F11 100
F22 200
Table myTbl:
ID Manager
---------------
8779631 MCM
Table myAllocation:
accountNumber unitPrice
--------------------------
292 300
DDL for the tables and their data:
CREATE TABLE dbo.ABC_myTbl
(
ID INT NOT NULL,
MANAGER VARCHAR(10) NOT NULL
)
CREATE TABLE dbo.myTbl
(
ID INT NOT NULL,
MANAGER VARCHAR(10) NOT NULL
)
CREATE TABLE dbo.ABC_myAllocation
(
accountNumber VARCHAR(10) NOT NULL,
unitprice NUMERIC(10, 3) NOT NULL
)
CREATE TABLE dbo.myAllocation
(
accountNumber VARCHAR(10) NOT NULL,
unitprice NUMERIC(10, 3) NOT NULL
)
INSERT INTO dbo.ABC_myTbl VALUES (8,'DOYLE')
INSERT INTO dbo.ABC_myAllocation VALUES ('F11',100)
INSERT INTO dbo.ABC_myAllocation VALUES ('F22',200)
INSERT INTO dbo.myTbl VALUES (8779631,'MCM')
INSERT INTO dbo.myAllocation VALUES ('292',300)

I didn't wait for your DDL and sample data population. So I created a conceptual sample for you. Please pay attention that the tables have implied relationships and they are used in the WHERE clauses.
SQL
-- DDL and sample data population, start
DECLARE #tbl1 TABLE (ID INT PRIMARY KEY, Manager VARCHAR(20));
INSERT INTO #tbl1 (ID, Manager) VALUES
(8, 'DOYLE'),
(9, 'XYZ');
DECLARE #tbl1Child TABLE (accountNumber CHAR(3) PRIMARY KEY, ParentID INT, unitPrice DECIMAL(10,2));
INSERT INTO #tbl1Child (accountNumber, ParentID, unitPrice) VALUES
('F11', 8, 100)
,('F22', 8, 200)
,('F70', 9, 770);
DECLARE #tbl2 TABLE (ID INT PRIMARY KEY, Manager VARCHAR(20));
INSERT INTO #tbl2 (ID, Manager) VALUES
(8779631, 'MCM')
,(8779555, 'TTT');
DECLARE #tbl2Child TABLE (accountNumber CHAR(3) PRIMARY KEY, ParentID INT, unitPrice DECIMAL(10,2));
INSERT INTO #tbl2Child (accountNumber, ParentID, unitPrice) VALUES
('292', 8779631, 300)
,('255', 8779555, 500);
-- DDL and sample data population, end
SELECT TOP(1) NULL
, (
SELECT *
, (
SELECT * FROM #tbl1Child AS c
WHERE p.ID = c.ParentID
FOR XML PATH('allocation_row'), TYPE
)
FROM #tbl1 AS p
FOR XML PATH('tradeTicket'), TYPE
)
, (
SELECT *
, (
SELECT * FROM #tbl2Child AS c
WHERE p.ID = c.ParentID
FOR XML PATH('allocation_row'), TYPE
)
FROM #tbl2 AS p
FOR XML PATH('tradeTicket'), TYPE
)
FROM #tbl1
FOR XML PATH(''), TYPE, ROOT('tradeTickets');
