This site has a technique to pass xml data around in Microsoft SQL Server:
DECLARE #productIds xml
SET #productIds ='<Products><id>3</id><id>6</id><id>15</id></Products>'
SELECT
ParamValues.ID.value('.','VARCHAR(20)')
FROM #productIds.nodes('/Products/id') as ParamValues(ID)
But what is the syntax if I add another field?
The following does NOT work:
DECLARE #productIds xml
SET #productIds ='<Products><id>3</id><descr>Three</descr><id>6</id><descr>six</descr><id>15</id><descr>Fifteen</descr></Products>'
SELECT
ParamValues.ID.value('.','VARCHAR(20)')
,ParamValues.descr.value('.','VARCHAR(20)')
FROM #productIds.nodes('/Products/id') as ParamValues(ID)
Note: Maybe I've constructed my xml wrong.
You need to use something like:
SELECT
ParamValues.ID.value('(id)[1]','VARCHAR(20)'),
ParamValues.ID.value('(descr)[1]','VARCHAR(20)')
FROM
#productIds.nodes('/Products') as ParamValues(ID)
That FROM statement there defines something like a "virtual table" called ParamValues.ID - you need to select the <Products> node into that virtual table and then access the properties inside it.
Furthermore, your XML structure is very badly chosen:
<Products>
<id>3</id>
<descr>Three</descr>
<id>6</id>
<descr>six</descr>
<id>15</id>
<descr>Fifteen</descr>
</Products>
You won't be able to select the individual pairs of id/descr - you should use something more like:
<Products>
<Product>
<id>3</id>
<descr>Three</descr>
</Product>
<Product>
<id>6</id>
<descr>six</descr>
</Product>
<Product>
<id>15</id>
<descr>Fifteen</descr>
</Product>
</Products>
Then you could retrieve all items using this SQL XML query:
SELECT
ParamValues.ID.value('(id)[1]','VARCHAR(20)') AS 'ID',
ParamValues.ID.value('(descr)[1]','VARCHAR(20)') AS 'Description'
FROM
#productIds.nodes('/Products/Product') as ParamValues(ID)
ID Descrition
3 Three
6 six
15 Fifteen
You must wrap each set of id and descr into one parent node. Say Row. Now you can access each pair like this.
DECLARE #productIds xml
SET #productIds ='<Products><Row><id>3</id><descr>Three</descr></Row><Row><id>6</id><descr>six</descr></Row><Row><id>15</id><descr>Fifteen</descr></Row></Products>'
SELECT
ParamValues.Row.query('id').value('.','VARCHAR(20)'),
ParamValues.Row.query('descr').value('.','VARCHAR(20)')
FROM #productIds.nodes('/Products/Row') as ParamValues(Row)

I have a column called Resume of type XML stored in a table in MS-SQL Server.
I want to retrieve all the candidates who are from the city Saginaw.
When I use the query
SELECT Resume.query('(: explicit namespace :)declare namespace ns="Namespace-Resume";
//ns:Address/ns:Addr.Location/ns:Location/ns:Loc.City')
FROM JobCandidate
I get all the values for the city which is fine but when I use the following query:
SELECT Resume.query('(: explicit namespace :)declare namespace ns="Namespace-Resume";
//ns:Location[#ns:Loc.City="Saginaw"]/ns:Name')
FROM JobCandidate
I get an error "There is not attribute named Loc.City".
The sample data is as below:
<ns:Resume xmlns:ns="Namespace-Resume">
<ns:Name>
<ns:Name.Prefix></ns:Name.Prefix>
<ns:Name.First>Shai</ns:Name.First>
<ns:Name.Middle></ns:Name.Middle>
<ns:Name.Last>Bassli</ns:Name.Last>
<ns:Name.Suffix></ns:Name.Suffix>
</ns:Name>
<ns:Address>
<ns:Addr.Type>Home</ns:Addr.Type>
<ns:Addr.Street>567 3rd Ave</ns:Addr.Street>
<ns:Addr.Location>
<ns:Location>
<ns:Loc.CountryRegion>US </ns:Loc.CountryRegion>
<ns:Loc.State>MI </ns:Loc.State>
<ns:Loc.City>Saginaw</ns:Loc.City>
</ns:Location>
</ns:Addr.Location>
</ns:Address>
</ns:Resume>
Your question is not all clear... I'll provide several approaches, one of them will hopefully point you the way (You can copy the whole lot into a query window and execute it stand-alone):
DECLARE #xml XML=
N'<ns:Resume xmlns:ns="Namespace-Resume">
<ns:Name>
<ns:Name.Prefix />
<ns:Name.First>Shai</ns:Name.First>

</ns:Name>
<ns:Address>

<ns:Loc.State>MI </ns:Loc.State>
<ns:Loc.City>Saginaw</ns:Loc.City>

</ns:Address>
</ns:Resume>';

FROM #xml.nodes(N'/Resume[(Address/Addr.Location/Location/Loc.City/text())[1]=sql:variable("#location")]') AS A(r);
UPDATE: The SELECT you provide in comment
The call to nodes() is missing? Try it like this:
DECLARE #location NVARCHAR(100)=N'Saginaw';
WITH XMLNAMESPACES(DEFAULT N'Namespace-Resume')
SELECT r.value(N'(Name/Name.First/text())[1]',N'nvarchar(max)')
,r.value(N'(Name/Name.Last/text())[1]',N'nvarchar(max)')
FROM JobCandidate
CROSS APPLY Resume.nodes(N'/Resume[(Address/Addr.Location/Location/Loc.City/text())[1]=sql:variable("#location")]') AS A(r);
UPDATE 2: Namespace according to your comment
DECLARE #xml XML=
N'<ns:Resume xmlns:ns="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/Resume">
<ns:Name>
<ns:Name.Prefix />

Using SQL Server 2005, is it possible to combine XML and add an attribute at same time?
Unfortunately, due to project restrictions, I need a SQL Server 2005 solution.
Consider the following, where I need to combine XML from multiple rows within a new <root> element...
; WITH [TestTable] AS (
SELECT 7 AS [PkId], CAST('<data><id>11</id><id>12</id></data>' AS XML) AS [Data]
UNION ALL
SELECT 12, CAST('<data><id>22</id></data>' AS XML)
UNION ALL
SELECT 43, CAST('<data><id>33</id></data>' AS XML)
)
SELECT (
SELECT XMLDATA as [*]
FROM (
SELECT [Data] AS [*]
FROM [TestTable]
FOR XML PATH(''), TYPE
) AS DATA(XMLDATA)
FOR XML PATH('root')
)
This produces the desired output of...
<root>
<data><id>11</id><id>12</id></data>
<data><id>22</id></data>
<data><id>33</id></data>
</root>
But what I need to do, if possible, is add an attribute to the existing data element in each of the rows with the PkId value. The desired output would then look like this...
<root>
<data pkid="7"><id>11</id><id>12</id></data>
<data pkid="12"><id>22</id></data>
<data pkid="43"><id>33</id></data>
</root>
My gut feeling is that this is going to be impossible without the use of a cursor, but if anybody knows a way of doing it I'd love to hear it.
At the request of #MattA, here is an example of some random data in the table...
[PkId] [UserId] [SubmittedDate] [Data]
1 1 2015-03-24 12:34:56 '<data><id>1</id><id>2</id></data>'
2 1 2015-03-23 09:15:52 '<data><id>3</id></data>'
3 2 2015-03-22 16:01:23 '<data><id>4</id><id>5</id></data>'
4 1 2015-03-21 13:45:34 '<data><id>6</id></data>'
Please note, that to make the question easier, I stated that I needed the PkId column as the attribute to the data. This is not actually the case - instead I need the [SubmittedDate] column to be used. I apologise if this caused confusion.
Using UserId=1 as a filter, the XML I would like from the above would be...
<root>
<data submitteddate="2015-03-24T12:34:56"><id>1</id><id>2</id></data>
<data submitteddate="2015-03-23T09:15:52"><id>3</id></data>
<data submitteddate="2015-03-21T13:45:34"><id>6</id></data>
</root>
The date would be formatted using the 126 date format available from CONVERT
Here's the quick answer for you. XML does support "modify", but shredding on a small data set like this works quite well too.
Code
--The existing XML
DECLARE #XML XML = '<root>
<data><id>11</id></data>
<data><id>22</id></data>
<data><id>33</id></data>
</root>'
--XML Shredded Back to a table
;WITH
ShreddedXML AS (
SELECT
ID = FieldAlias.value('(id)[1]','int')
FROM
#XML.nodes('/root/data') AS TableAlias(FieldAlias)
), ArbitraryPKGenerator AS (
SELECT CURRENT_TIMESTAMP AS PKid,
ID
FROM ShreddedXML
)
SELECT A.PKId AS "#PKid",
A.ID AS "id"
FROM ArbitraryPKGenerator AS A
FOR XML PATH('data'), ROOT('root')
And the XML
<root>
<data PKid="2015-03-24T09:44:55.770">
<id>11</id>
</data>
<data PKid="2015-03-24T09:44:55.770">
<id>22</id>
</data>
<data PKid="2015-03-24T09:44:55.770">
<id>33</id>
</data>
</root>
I'm fairly new to querying XML datatypes. We receive XMLs from partners and one such partner sends us XMLs like this:
DECLARE #ResultData XML = '<outGoing xmlns="urn:testsystems-com:HH.2015.Services.Telephony.OutGoing">
<customer>
<ID>158</ID>
</customer>
</outGoing>'
In this example, I would like to pull only the ID out of the XML, but it seems the xmlns is preventing me from getting anything inside the XML:
SELECT cust.value('(ID)[1]', 'VARCHAR(40)') as 'CustomerID'
FROM #ResultData.nodes('/outGoing/customer') as t(cust)
returns NUll, but if I manually remove the XMLNS from the XML I get 158.
I've experimented with WITH XMLNAMESPACES to see if I could use that, but I'm obviously missing something. Since these XMLs will be coming in automatically, I would like to be able to parse the XML, but right now I'm stuck.
That should work:
DECLARE #ResultData XML = '<outGoing xmlns="urn:testsystems-com:HH.2015.Services.Telephony.OutGoing">
<customer>
<ID>158</ID>
</customer>
</outGoing>'
;WITH XMLNAMESPACES(DEFAULT 'urn:testsystems-com:HH.2015.Services.Telephony.OutGoing')
SELECT
#ResultData.value('(/outGoing/customer/ID)[1]', 'int')
or to use your approach:
;WITH XMLNAMESPACES(DEFAULT 'urn:testsystems-com:HH.2015.Services.Telephony.OutGoing')
SELECT
CustomerID = cust.value('(ID)[1]', 'INT')
FROM
#ResultData.nodes('/outGoing/customer') as t(cust)
This will return 158 as its value.
I've used WITH XMLNAMESPACES(DEFAULT .....) since this is the only XML namespace in play, and it's defined at the top-level node - so it applies to every node in the XML structure.
I am using SQL Server 2008. I have a field called RequestParameters in one of my SQL table called Requests with XML data. An example would be:
<RequestParameters xmlns="http://schemas.datacontract.org/2004/07/My.Name.Space" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:z="http://schemas.microsoft.com/2003/10/Serialization/" z:Id="1">
<Data z:Id="2" i:type="CheckoutRequest">
<UserGuid>7ec38c44-5aa6-49e6-9fc7-25e9028f2148</UserGuid>
<DefaultData i:nil="true" />
</Data>
</RequestParameters>
I ultimately want to retrieve the value of UserGuid. For that, I am doing this:
SELECT RequestParameters.value('(/RequestParameters/Data/UserGuid)[0]', 'uniqueidentifier') as UserGuid
FROM Requests
However, the results I am seeing are all NULL. What am I doing wrong?
You have to specify the default namespace and use [1] instead of [0].
WITH XMLNAMESPACES(default 'http://schemas.datacontract.org/2004/07/My.Name.Space')
SELECT RequestParameters.value('(/RequestParameters/Data/UserGuid)[1]', 'uniqueidentifier') as UserGuid
FROM Requests;
SQL Fiddle
declare #XML xml
set #XML = "<RequestParameters xmlns="http://schemas.datacontract.org/2004/07/My.Name.Space" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:z="http://schemas.microsoft.com/2003/10/Serialization/" z:Id="1">
<Data z:Id="2" i:type="CheckoutRequest">
<UserGuid>7ec38c44-5aa6-49e6-9fc7-25e9028f2148</UserGuid>
<DefaultData i:nil="true" />
</Data>
</RequestParameters>"
select #XML.value('(/RequestParameters/Data /UserGuid)[1]', 'varchar')

Before data is removed from an sql server database, it is exported and saved as an XML file in the event that this data is to be recovered at a later stage. I am now trying to get the data back into the database from an XML file but cannot find the best way to do this. The SQL server import / export wizard does not appear to support XML. I have looked at the XML Bulk Load component but this doesn't look like it would work for my issue. Has anyone any suggestions?
The XML may look like below and I woud want each row inserting:
