If I have:
<quotes>
<quote>
<name>john</name>
<content>something or other</content>
</quote>
<quote>
<name>mary</name>
<content>random stuff</content>
</quote>
</quotes>
How do I get a list of the element names 'name' and 'content' using T-SQL?
The best I've got so far is:
declare #xml xml
set #xml = ...
select r.value('quotes/name()[1]', 'nvarchar(20)' as ElementName
from #xml.nodes('/quotes') as records(r)
But, of course, I can't get this to work.
Actually, sorry, the best I've got is:
select distinct r.value('fn:local-name(.)', 'nvarchar(50)') as t
FROM
#xml.nodes('//quotes/*/*') AS records(r)
Guess I answered my own question...
DECLARE #xml as xml
SET #xml = '<Address><Home>LINE1</Home></Address>'
SELECT Nodes.Name.query('local-name(.)') FROM #xml.nodes('//*') As Nodes(Name)
This will give the list of all elements

I have the following XML and I want to extract the FieldValue using SQL. How can I do this?
<Field Group="Annuitant">
<FieldName>Contract Number</FieldName>
<FieldValue>TR13116544</FieldValue>
</Field>
Thanks
DECLARE #xml XML=
'<Field Group="Annuitant">
<FieldName>Contract Number</FieldName>
<FieldValue>TR13116544</FieldValue>
</Field>';
--the lazy approach
SELECT #xml.value('(//FieldValue)[1]','varchar(50)')
--Better
SELECT #xml.value('(/Field/FieldValue)[1]','varchar(50)')
--This is, what you should do: Be as specific as possible...
SELECT #xml.value('(/Field/FieldValue/text())[1]','varchar(50)')
If there are - what I assume - are several <Field> elements and you need to pick the rigth one, you can do something like this:
DECLARE #name VARCHAR(100)='Contract Number';
SELECT #xml.value('(/Field[(FieldName/text())[1]=sql:variable("#name")]/FieldValue/text())[1]','varchar(50)')
Hint: Your question is not very clear, that needs a lot of guessing on my side. For your next question I ask you to be more specific.
Sample code:
DECLARE #MyXML XML
SET #MyXML ='<SampleXML>
<Fruits>
<Fruits1>Apple</Fruits1>
<Fruits2>Pineapple</Fruits2>
</Fruits>
</SampleXML>'
SELECT
a.b.value('Fruits[1]/Fruits1[1]','varchar(10)') AS Fruits1,
a.b.value('Fruits[1]/Fruits2[1]','varchar(10)') AS Fruits2
FROM #MyXML.nodes('SampleXML') a(b)
In oracle you can do the following:
WITH TABL (FIELD) AS (
select xmltype('<Field Group="Annuitant">
<FieldName>Contract Number</FieldName>
<FieldValue>TR13116544</FieldValue>
</Field>') from dual
)
SELECT
EXTRACTVALUE(FIELD,'/Field/FieldName') AS FIELDNAME,
EXTRACTVALUE(field,'/Field/FieldValue') AS FieldValue
FROM TABL ;
I have a column in my SQL database that is called Triggers_xml_data and its type is ntext. The column is in a xml format and I am trying to get a value from a certain part of the xml. I seen an example of this being done without a column like this:
declare #fileContent xml
set #fileContent ='<my:Header>
<my:Requestor>Mehrlein, Roswitha</my:Requestor>
<my:RequestorUserName>SJM\MehrlR01</my:RequestorUserName>
<my:RequestorEmail>RMehrlein#SJM.com</my:RequestorEmail>
<my:HRContact>Roswita Mehrlein, Beatrice Porta</my:HRContact>
<my:Entity>SJM Germany</my:Entity>
<my:Department>HR/Administration</my:Department>
<my:PositionTitle>Sales Representative</my:PositionTitle>
<my:JobDescription>x0lGQRQAAAABAAAAAAAAAAAeAQAyAAAAVgBAAAAA=</my:JobDescription>
<my:PositionDepartment>Sales</my:PositionDepartment>'
;WITH XMLNAMESPACES ('http://schemas.microsoft.com/office/infopath/2003/myXSD/2005-08-29T12-58-51' as my)
select #fileContent.value('(//my:PositionDepartment)[1]', 'varchar(255)')
But I want to select my column like this:
Declare #filevalue xml
select de.triggers_xml_data
from dbo.DEPLOYMENT_ENVIRONMENT as de
But this is not working and I tried to use this #filecontent.value('(//value)[1]','varchar(255)') and making it equal the column value, I have tried casting it but I can't find a way to do this. Is this possible?
When I do this:
SELECT
CAST(
REPLACE(CAST(de.TRIGGERS_XML_DATA AS VARCHAR(MAX)), 'encoding="utf-16"', '')
AS XML).value('(triggers/triggerDefinition/config/item/value)[1]', 'NVARCHAR(max)') as Item, de.ENVIRONMENT_ID
from dbo.DEPLOYMENT_ENVIRONMENT as de
where de.ENVIRONMENT_ID = 19234819
I am getting a null value returned.
Here is an example of what my xml could look like:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<configuration xml:space="preserve">
<triggers>
<defined>true</defined>
<triggerDefinition>
<id>1</id>
<name>After successful deployment</name>
<userDescription/>
<isEnabled>true</isEnabled>
<pluginKey>com.atlassian.bamboo.triggers.atlassian-bamboo-triggers:afterSuccessfulDeployment</pluginKey>
<triggeringRepositories/>
<config>
<item>
<key>deployment.trigger.afterSuccessfulDeployment.triggeringEnvironmentId</key>
<value>19234819</value>
</item>
</config>
</triggerDefinition>
</triggers>
<bambooDelimiterParsingDisabled>true</bambooDelimiterParsingDisabled>
</configuration>
The XML, as you posted it, is not valid. Your code example does not work... It is not allowed to use a namespace prefix without a namespace declaration. Furthermore your example misses the closing Header-tag...
I corrected this...
DECLARE #yourTbl TABLE(ID INT, YourXML NTEXT);
INSERT INTO #yourTbl VALUES
(1,N'<my:Header xmlns:my="DummyUrl">
<my:Requestor>Mehrlein, Roswitha</my:Requestor>
<my:RequestorUserName>SJM\MehrlR01</my:RequestorUserName>
<my:RequestorEmail>RMehrlein#SJM.com</my:RequestorEmail>
<my:HRContact>Roswita Mehrlein, Beatrice Porta</my:HRContact>
<my:Entity>SJM Germany</my:Entity>
<my:Department>HR/Administration</my:Department>
<my:PositionTitle>Sales Representative</my:PositionTitle>
<my:JobDescription>x0lGQRQAAAABAAAAAAAAAAAeAQAyAAAAVgBAAAAA=</my:JobDescription>
<my:PositionDepartment>Sales</my:PositionDepartment>
</my:Header>');
--Lazy approach
SELECT ID
,CAST(CAST(YourXml AS NVARCHAR(MAX)) AS XML).value(N'(//*:PositionDepartment)[1]','nvarchar(max)')
FROM #yourTbl;
--explicit approach
WITH XMLNAMESPACES('DummyUrl' AS my)
SELECT ID
,CAST(CAST(YourXml AS NVARCHAR(MAX)) AS XML).value(N'(/my:Header/my:PositionDepartment)[1]','nvarchar(max)')
FROM #yourTbl
Some Background
If possible you should not store XML in other format than XML and further more one should avoid NTEXT, as it is depricated since SS2005!.
You have to cast NTEXT to NVARCHAR(MAX) first, than cast this to XML. The second will break, if the XML is not valid. That means: If the XML is really the way you posted it, this cannot work!
UPDATE: String-based approach, if XML does not work
If you cannot cast this to XML you might try this
--String based
WITH Casted AS
(
SELECT ID
,CAST(YourXML AS NVARCHAR(MAX)) AS TheXmlAsString
FROM #yourTbl
)
,WithPosition AS
(
SELECT Casted.*
,CHARINDEX(N'<my:PositionDepartment>',TheXmlAsString) + LEN(N'<my:PositionDepartment>') AS FirstLetter
FROM Casted
)
SELECT ID
,SUBSTRING(TheXmlAsString,FirstLetter,CHARINDEX('<',TheXmlAsString,FirstLetter)-FirstLetter)
FROM WithPosition
UPDATE 2
According to your edit the following returns a NULL value. This is good, because it shows, that the cast was successfull.
SELECT
CAST(
REPLACE(CAST(de.TRIGGERS_XML_DATA AS VARCHAR(MAX)), 'encoding="utf-16"', '')
AS XML).value('(triggers/triggerDefinition/config/item/value)[1]',
'NVARCHAR(max)') as Item, de.ENVIRONMENT_ID
from dbo.DEPLOYMENT_ENVIRONMENT as de
where de.ENVIRONMENT_ID = 19234819
Try this (skip namespace with wildcard):
SELECT
CAST(
REPLACE(CAST(de.TRIGGERS_XML_DATA AS VARCHAR(MAX)), 'encoding="utf-16"', '')
AS XML).value('(*:triggers/*:triggerDefinition/*:config/*:item/*:value)[1]', 'NVARCHAR(max)') as Item, de.ENVIRONMENT_ID
from dbo.DEPLOYMENT_ENVIRONMENT as de
where de.ENVIRONMENT_ID = 19234819
And this should be even better:
SELECT
CAST(CAST(de.TRIGGERS_XML_DATA AS NVARCHAR(MAX)) AS XML).value('(*:triggers/*:triggerDefinition/*:config/*:item/*:value)[1]', 'NVARCHAR(max)') as Item, de.ENVIRONMENT_ID
from dbo.DEPLOYMENT_ENVIRONMENT as de
where de.ENVIRONMENT_ID = 19234819
UPDATE 3
I'd rather cut away the full declaration. Your posted example would go like this
DECLARE #DEPLOYMENT_ENVIRONMENT TABLE(ENVIRONMENT_ID INT, TRIGGERS_XML_DATA NTEXT);
INSERT INTO #DEPLOYMENT_ENVIRONMENT VALUES
(19234819,N'<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<configuration xml:space="preserve">
<triggers>
<defined>true</defined>

<id>1</id>

<value>19234819</value>
</item>
</config>
</triggerDefinition>

<bambooDelimiterParsingDisabled>true</bambooDelimiterParsingDisabled>
</configuration>');

(
SELECT CAST(de.TRIGGERS_XML_DATA AS NVARCHAR(MAX)) AS XmlAsSting
FROM #DEPLOYMENT_ENVIRONMENT as de

)

I have an XML file in a format similar to:
<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>
I need to write a query that will get all of the element values that start with Field. So given the XML above the result should be
FieldVal
--------
100
200
300
I've tried the following but it does not work:
Select
xc.value('text()', 'int')
From
#XMLData.nodes('/XML/[starts-with(name(), ''Field'')]') As xt(xc)
NOTE: I am well aware that this task could be easily done if I reformatted my XML but unfortunately I have no control over the format of the XML.
One way is
declare #XMLData xml ='<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>'
Select
xc.value('.', 'int')
From #XMLData.nodes('/XML/*') As xt(xc)
WHERE xc.value('local-name(.)', 'varchar(50)') LIKE 'Field%'
Prefix name with special character and check contains instead.
declare #x xml ='<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>';
select t.n.value('.','varchar(100)')
from #x.nodes ('XML/*[contains(concat("$",local-name()),"$Field")]') t(n);
I think it's this what you are looking for:
DECLARE #xml XML=
'<XML>
<Field1>100</Field1>
<Field2>200</Field2>
<Field3>300</Field3>
<Test>400</Test>
</XML>';
SELECT Fld.value('.','int') AS FieldOnly
FROM #xml.nodes('/XML/*[substring(local-name(.),1,5)="Field"]') AS A(Fld)
Just because of the discussion in comments:
DECLARE #fldName VARCHAR(100)='Field';
SELECT Fld.value('.','int') AS FieldOnly
FROM #xml.nodes('/XML/*[substring(local-name(.),1,string-length(sql:variable("#fldName")))=sql:variable("#fldName")]') AS A(Fld)
Change the first line to "Test" (case sensitive!), and you'd get just the one row with 400...
<ROOT>
<arn>arn001</arn>
<arn>arn002</arn>
</ROOT>
Tried the following code though
SELECT
ARN.value('(//arn/text())[1]','VARCHAR(100)') AS arns --TAG
FROM
#xml.nodes('/ROOT')AS TEMPTABLE(ARN)
It returns only first value
Try this way :
declare #xml xml = '<ROOT>
<arn>arn001</arn>
<arn>arn002</arn>
</ROOT>'
SELECT
X.value('.','VARCHAR(100)') AS arns
FROM
#xml.nodes('/ROOT/arn')AS T(X)
SQL Fiddle
I am unsure how to get the value of dc:creator from an RSS-feed using SQL.
This is my xml/rss-feed:
<rss xmlns:dc="http://purl.org/dc/elements/1.1/" version="2.0">
<channel>
<title>Foobar RSS</title>
<link>http://www.foobar.com/</link>
<description>RSS feed</description>
<language>en</language>
<ttl>15</ttl>
<item>
<title>This is my title</title>
<link>http://www.foobar.com/link/blabla</link>
<description>Bla..bla..bla..</description>
<dc:creator>John Doe</dc:creator>
<guid isPermaLink="false">00082EA751F1D905DE00E7CFA2417DA9</guid>
<pubDate>Wed, 26 Oct 2011 00:00:00 +0200</pubDate>
</item>
</channel>
</rss>
In my SQL I use something like this to get the values - e.g for pubDate I use something like this:
DECLARE #xml XML
SET #xml = cast('my rss feed here' AS xml)
SELECT
convert(datetime,substring(T.nref.value('pubDate[1]','nvarchar(100)'),6,20)) as pubdate,
FROM #xml.nodes('//item') AS T(nref)
This works fine, but when I am trying to get dc:creator value 'John Doe', the following just gives me an error:
SELECT
T.nref.value('dc:creator','nvarchar(100)') as creator
FROM #xml.nodes('//item') AS T(nref)
error:
XQuery [value()]: The name "dc" does not denote a namespace.
I need to be able to select multiple columns from the rss-feed. Can anybody provide a solution or direction to get the value of dc:creator?
I have another question - how would you construct the code if you are doing it in a sub select?
E.g.
INSERT INTO RSSResults (ID, pubDate)
SELECT #ID, tbl.pubDate FROM (
;WITH XMLNAMESPACES('http://purl.org/dc/elements/1.1/' AS dc)
SELECT
RSS.Item.value('(dc:creator)[1]', 'nvarchar(100)') as pubDate
FROM
#xml.nodes('/rss/channel/item') as RSS(Item)) AS tbl
The code breaks at ";WITH XMLNAMESPACES". Is it possible to include the namespace directly in the statement somehow?
Try something like this:
DECLARE #xml XML
SET #xml = cast('my rss feed here' AS xml)
;WITH XMLNAMESPACES('http://purl.org/dc/elements/1.1/' AS dc)
SELECT
#xml.value('(rss/channel/item/dc:creator)[1]', 'nvarchar(100)')
If you need to catch multiple items - try this:
DECLARE #xml XML
SET #xml = cast('my rss feed here' AS xml)
;WITH XMLNAMESPACES('http://purl.org/dc/elements/1.1/' AS dc)
SELECT
RSS.Item.value('(dc:creator)[1]', 'nvarchar(100)')
FROM
#xml.nodes('/rss/channel/item') as RSS(Item)
