Input data
id year Name provid prov
1 1995 MAC 1995-11_CL236 reg 236
1 1995 MAC 1995-11_CL230 reg 230 (1)
1 1995 MAC 1995-11_CL229J reg 229J
1 1995 MAC 1995-11_CL260 reg 260
My query looks like this
select
id, year, Name, prov, provid
from
Table
for xml path ('entry'), root('legref'), elements
The above Query generating different entry for each row. But I need group by id year, name and provide single entry with different prov and provid.
<legref>

XML select statement to loop over all rows

I have
mytable consists of one XMLTYPE column called 'RS'. RS contains:
<test>
<mycol>
<name>a</name>
<number>1</number>
<number>2</number>
<number>50</number>
<number>60</number>
</mycol>
<mycol>
<name>b</name>
<number>5</number>
<number>820</number>
<number>601</number>
</mycol>
<mycol>
<name>c</name>
<number>6</number>
<number>8</number>
<number>62</number>
</mycol>
etc...
</test>
I'm looking to run a select statement that will display ALL names and up to 2 numbers from mytable.
something like this select statement but for all rows and without calling mycol[] several times.
select a.RS.extract('/test/mycol[1]/name[1]/text()').getstringval() as Names,
a.RS.extract('/test/mycol[1]/a[1]/text()').getstringval() ||''||
a.RS.extract('/test/mycol[1]/a[2]/text()').getstringval() ||''||
a.RS.extract('/test/mycol[1]/a[3]/text()').getstringval()
as num
from mytable a;/
output should be:
Names | num
a | 1 2
b | 5 820
c | 6 8
etc...
Thanks in advance.

How to iterate through every potential XML subelement using SQL Server

I have a large XML file of over 45K contacts and I need to iterate through their subelement transactions into a SQL table. I've looked at several solutions to this, using value(), node(), etc..., but no examples appear to have an XML structure close to mine:
<Contacts>
<Contact>
<ContactID>1234</ContactID>
<ContactName>’John Doe’</ContactName>
<DOB>09031978</DOB>
<Address>’123 Main Street’</Address>
<Transactions>
<Transaction>
<TransactionID>4490</TransactionID>
<ProductName>’Recliner’</ProductName>
<Cost>123.00</Cost>
<PurchaseDate>07042020
</Transaction>
<Transaction>
<TransactionID>5678</TransactionID>
<ProductName>’Lamp’</ProductName>
<Cost>45.00</Cost>
<PurchaseDate>07042020
<Transaction>
</Transactions>
</Contact>
<Contact>
<ContactID>4567</ContactID>
<ContactName>’Jane Doe’</ContactName>
<DOB>05191984</DOB>
<Address>’567 Fake Street’</Address>
<Transactions>
<Transaction>
<TransactionID>4378</TransactionID>
<ProductName>’Coffee Table’</ProductName>
<Cost>225.00</Cost>
<PurchaseDate>07042018
</Transaction>
</Transactions>
</Contact>
</Contacts>
I need these data in a result like below:
ContactID
TransactionID
ProductName
Cost
PurchaseDate
1234
4490
Recliner
123.00
4 July 2020
1234
5678
Lamp
45.00
4 July 2020
4567
4378
Coffee Table
225.00
4 July 2018
I've tried a query using the following script:
EXEC sp_xml_preparedocument #idoc OUTPUT, #doc
-- Execute a SELECT stmt using OPENXML rowset provider.
SELECT *
FROM OPENXML (#idoc, '/Contacts/Contact/Transactions/Transaction',2)
WITH (ContactID int '../ContactID',
TransactionID int 'TransactionID',
ProductName nvarchar(50) 'ProductName',
Cost float 'Cost',
PurchaseDate date 'PurchaseDate')
But this will return either a null for ContactID; or return only one transaction for each ContactID. But I need it to iterate and get as many transactions as exist for a contact.
Any insights would be most welcome!
Try to avoid sp_xml_preparedocument because it uses large amounts of memory that can't be used by SQL Server until you remember to free it up by invoking sp_xml_removedocument.
What you're asking for can be easily achieved using nodes() with a cross apply, e.g. (after fixing your XML sample):
declare #doc xml = N'<Contacts>
<Contact>
<ContactID>1234</ContactID>
<ContactName>’John Doe’</ContactName>
<DOB>09031978</DOB>
<Address>’123 Main Street’</Address>
<Transactions>
<Transaction>
<TransactionID>4490</TransactionID>
<ProductName>’Recliner’</ProductName>
<Cost>123.00</Cost>
<PurchaseDate>07042020</PurchaseDate>
</Transaction>
<Transaction>
<TransactionID>5678</TransactionID>
<ProductName>’Lamp’</ProductName>
<Cost>45.00</Cost>
<PurchaseDate>07042020</PurchaseDate>
</Transaction>
</Transactions>
</Contact>
<Contact>
<ContactID>4567</ContactID>
<ContactName>’Jane Doe’</ContactName>
<DOB>05191984</DOB>
<Address>’567 Fake Street’</Address>
<Transactions>
<Transaction>
<TransactionID>4378</TransactionID>
<ProductName>’Coffee Table’</ProductName>
<Cost>225.00</Cost>
<PurchaseDate>07042018</PurchaseDate>
</Transaction>
</Transactions>
</Contact>
</Contacts>';
select
Cont.value('ContactID[1]', 'int') as ContactID
,Trans.value('TransactionID[1]', 'int') as TransactionID
,Trans.value('ProductName[1]', 'nvarchar(50)') as ProductName
,Trans.value('Cost[1]', 'float') as Cost
,convert(date, concat(substring(purDate,1,2), '/', substring(purDate,3,2), '/', substring(purDate,5,4)), 101) as PurchaseDate
from #doc.nodes('//Contact') nodes1(Cont)
cross apply nodes1.Cont.nodes('Transactions/Transaction') nodes2(Trans)
outer apply (
select purDate = Trans.value('PurchaseDate[1]', 'nvarchar(8)')
) temp;
Which yields:
ContactID
TransactionID
ProductName
Cost
PurchaseDate
1234

Grouping values under elements FOR XML

I am trying to format the output of a query using FOR XML in SQL Server 2012.
Each PART_NO can have a varying number of SUPPLIER_PART_NUMBER's mapped to it.
The table has data in the following format.
PART_NO SUPPLIER_PART_NO
------- ----------------
AAA 1
AAA 2
BBB 3
BBB 4
BBB 5
The desired output is as follows where part AAA has two supplier part numbers and part BBB has three supplier part numbers, and the supplier part numbers are nested below the part number.
<root>
<item PartNo ="AAA">
<mpn>1</mpn>
<mpn>2</mpn>
</item>
<item PartNo ="BBB">
<mpn>3</mpn>
<mpn>4</mpn>
<mpn>5</mpn>
</item>
</root>
The closest I can get is below, but this does not group the mpn under PartNo:
SELECT
[PART_NO] as 'item/#PartNo',
[SUPPLIER_PART_NO] as 'mpn'
FROM
[dbo].[supplier_part_mapping2]
ORDER BY
PART_NO
FOR XML PATH('') , ROOT('root');
Thank you in advance
Try this:
SELECT
p1.PART_NO as 'item/#PartNo',
(SELECT
SUPPLIER_PART_NO AS 'mpn'
FROM
[dbo].[supplier_part_mapping2] p2
WHERE
p1.PART_NO = p2.PART_NO
FOR XML PATH(''), TYPE) AS 'item'
FROM
[dbo].[supplier_part_mapping2] p1
GROUP BY
PART_NO
ORDER BY
PART_NO
FOR XML PATH('') , ROOT('root');
This should produce:
You basically need to group by the PART_NO so that you get only one <item> entry for each distinct PART_NO, and you need to grab the "sub-elements" as a subquery to list them all together under one parent node.

How to Select distinct values in FOR XML PATH?

Given the following tables where T_DATA.ID = PARENT_ID or CHILD.ID
Name: T_DATA
+----+------+--------+
| ID | CODE | VALUE |
+----+------+--------+
| 1 | 3186 | value1 |
| 2 | 3186 | value2 |
| 3 | 3189 | value3 |
| 4 | 3189 | value4 |
| 5 | 3190 | value5 |
+----+------+--------+
Name: T_DATA_LINK
+-----------+----------+
| PARENT_ID | CHILD_ID |
+-----------+----------+
| 1 | 3 |
| 1 | 4 |
+-----------+----------+
I want to return an xml structure like this:
<ITEM_LIST>
<ITEM>
<CODE>3186</CODE>
<ROWS>
<ROW>
<ID>1</ID>
<ROW_INDEX>0</ROW_INDEX>
<VALUE>value1</VALUE>
</ROW>
<ROW>
<ID>2</ID>
<ROW_INDEX>1</ROW_INDEX>
<VALUE>value2</VALUE>
</ROW>
</ROWS>
</ITEM>
<ITEM>
<CODE>3189</CODE>
<ROWS>
<ROW>
<ID>3</ID>
<ROW_INDEX>0</ROW_INDEX>
<VALUE>value3</VALUE>
</ROW>
<ROW>
<ID>4</ID>
<ROW_INDEX>1</ROW_INDEX>
<VALUE>value4</VALUE>
</ROW>
</ROWS>
</ITEM>
<ITEM>
<CODE>3190</CODE>
<VALUE>value5</VALUE>
</ITEM>
</ITEM_LIST>
The ROW_INDEX is incremented by 1 for every ROW.
I need the T_DATA_LINK table to know whether an ITEM has a parent or not.
If it has a parent it means that there is more than one record with that CODE value and they need to be displayed as ROWS, otherwise it has to be displayed as a single ITEM.
UPDATE
I actually need to check the T_DATA_LINK table since there may be cases where an ITEM has a parent and only one record, but it still need to be displayed as a ROW.
#Shnugo I tried your solution, but even if now I get the correct values inside the ROWS, I get duplicates for each ITEM that has more than one record.
This is probably because I had to add to the GROUP BY the other fields I need to return with the SELECT which I didn't add to the example in order to keep it simpler.
For example, the ID need to be displayed at the ITEM level for the items which don't have any ROWS.
UPDATE 2
#Shnugo you are correct. Items 3 and 4 are the children of Item 1, but you don't see the relationship in the xml.
All the items are unique, always.
The items that are referenced in T_DATA_LINK are still unique, but are linked to each other in my application where they are displayed inside a table.
Basically the PARENT is the first column of the table and the children are the others columns.
This is the updated output I want to get.
ID should be always -1 for the items that have rows.
PARENT_CODE should be the CODE of the parent (if the item is a parent then it is equal to the CODE)
<ITEM_LIST>
<ITEM>
<ID>-1</ID>
<CODE>3186</CODE>
<PARENT_CODE>3186</PARENT_CODE>
<ROWS>
<ROW>
<ID>1</ID>
<ROW_INDEX>0</ROW_INDEX>
<VALUE>value1</VALUE>
</ROW>
<ROW>
<ID>2</ID>
<ROW_INDEX>1</ROW_INDEX>
<VALUE>value2</VALUE>
</ROW>
</ROWS>
</ITEM>
<ITEM>
<ID>-1</ID>
<CODE>3189</CODE>
<PARENT_CODE>3186</PARENT_CODE>
<ROWS>
<ROW>
<ID>3</ID>
<ROW_INDEX>0</ROW_INDEX>
<VALUE>value3</VALUE>
</ROW>
<ROW>
<ID>4</ID>
<ROW_INDEX>1</ROW_INDEX>
<VALUE>value4</VALUE>
</ROW>
</ROWS>
</ITEM>
<ITEM>
<ID>5</ID>
<CODE>3190</CODE>
<VALUE>value5</VALUE>
</ITEM>
</ITEM_LIST>

</ROWS>
</ITEM>
<ITEM>
<ID>5</ID>
<CODE>3190</CODE>
<VALUE>value5</VALUE>

XML will omit any NULL value. The WHERE clause in the subselects will return with NULL if there's nothing found...

Querying SQL for grouped data and receiving it in BizTalk?

I have a query that returns data organized by group. I am wanting to have them come out in a grouped XML similar to the format below. I am planning to pass it in as a XML message into BizTalk using the WCF-SQL port adapter.
Data:
ID GroupID Item ID FileName

6 3 6 File003.txt
7 3 7 File003.txt
8 null 8 File004.txt
9 null 9 File005.txt
XML Ouput (input to BizTalk)
<GroupInfo ID=1 FileName=File001.txt>
<Items>
<Item ID=1 />
<Item ID=2 />

</Items>
</GroupInfo>
I'm not sure what to do to get the output in the required format. Please help.
To accomplish this, you would have to use FOR XML results from the Stored Procedure.
All documented here: http://technet.microsoft.com/en-us/library/ms178107.aspx
In this case, you might find it easier to join the table to itself on GroupID as FOR XML AUTO will automatically create child records for the joined rows.
