This query returns the attribute value "storedId1"
SET #xml = N'<Data>
<Ref ID="1" sf="storedId1">
this is the value I want
</Ref>
</Data>'
SELECT
T.C.value('#sf', 'nvarchar(MAX)') AS result
FROM
#xml.nodes('Data/Ref') T(C)
WHERE
T.C.value('#sf', 'nvarchar(MAX)') = 'storedId1'
How can I return the node value instead .i.e. return "this is the value i want"
I guess I need to change the SELECT to something like
SELECT T.C.value('Data/Ref', 'nvarchar(MAX)') AS result
But it fails with
XQuery [value()]: 'value()' requires a singleton (or empty sequence), found operand of type 'xdt:untypedAtomic *'
Try this:
SELECT
T.C.value('(./text())[1]', 'nvarchar(MAX)') AS result
FROM
#xml.nodes('Data/Ref[#sf="storedId1"]') T(C)
DECLARE #xml xml
SET #xml = N'<Data>
<Ref ID="1" sf="storedId1">
this is the value I want
</Ref>
</Data>'
SELECT
T.C.value('.', 'nvarchar(MAX)') AS result
FROM
#xml.nodes('Data/Ref') T(C)
WHERE
T.C.value('#sf', 'nvarchar(MAX)') = 'storedId1'

There are 3 attributes I am trying to return when reading this xml file. 2 of the 3 are returning expected values. I can not figure out why I can't get the id to return the value. It always returns NULL. How can I get the proper value of rid1 and rid2

You need to prefix the attribute with the namespace like so:
SELECT
doc.col.value('#name', 'nvarchar(10)') sheet
,doc.col.value('#a:id', 'nvarchar(max)') rid
,doc.col.value('#sheetId', 'int') id
FROM #xml.nodes('*:workbook/sheets/sheet') doc(col)
Give your namespaces the same aliases in your T-SQL as they have in your XML and use the namespace alias in your reference:
WITH XMLNAMESPACES (DEFAULT 'http://schemas.openxmlformats.org/spreadsheetml/2006/main',
'http://schemas.openxmlformats.org/officeDocument/2006/relationships' AS r,
'http://schemas.openxmlformats.org/markup-compatibility/2006' AS mc,
'http://schemas.microsoft.com/office/spreadsheetml/2010/11/main' AS x15,
'http://schemas.microsoft.com/office/spreadsheetml/2010/11/ac' AS x15ac)
SELECT doc.col.value('#name', 'nvarchar(10)') sheet,
doc.col.value('#r:id', 'nvarchar(max)') rid,
doc.col.value('#sheetId', 'int') id
FROM #xml.nodes('*:workbook/sheets/sheet') doc(col);
What am I not getting here? I can't get any return except NULL...

'http://schemas.xmlsoap.org/soap/envelope/' as [soap])
SELECT Data.value('(/soap:Envelope/soap:Body/webregdataResponse/errorFlag)[1]','int') AS ErrorFlag
FROM #Table ;
Running the above SQL will return 99.
Snapshot of the result is given below,
That's because errorFlag is not the root element of your XML document. You can either specify full path from root element to errorFlag, for example* :
SELECT #nodeVal = #xml.value('(/*/*/*/errorFlag)[1]', 'int')
or you can use descendant-or-self axis (//) to get element by name regardless of it's location in the XML document, for example :
SELECT #nodeVal = #xml.value('(//errorFlag)[1]', 'int')
*: I'm using * instead of actual element name just to simplify the expression. You can also use actual element names along with the namespaces, like demonstrated in the other answer.
I'm retrieving xml formatted text from ntext fields (sample format of a row below):
<root>
<DocInfo>
<CompanyName>Some Company</CompanyName>
<WebsiteUrl>http://www.someurl.com</WebsiteUrl>
<PrimaryServices>Benefits Administration</PrimaryServices>
<PrimaryServices>Payroll Processing</PrimaryServices>
<SecondaryServices>Background Checking</SecondaryServices>
<SecondaryServices>HR Outsourcing</SecondaryServices>
<SecondaryServices>Comp & Benefits</SecondaryServices>
<SecondaryServices>Administration</SecondaryServices>
</DocInfo>
</root>
Using this sql I am retrieving the single node values:
select #xmlString = COALESCE(#xmlString + '', '') + cast(content_html as nvarchar(max)) FROM content where folder_id = 18
set #xmlString = replace(#xmlString,'<?xml version="1.0" encoding="UTF-16" standalone="yes"?>','')
set #XML = cast(#xmlString as xml)
Select
T.N.value('CompanyName[1]', 'varchar(250)') as CompanyName,
T.N.value('WebsiteUrl[1]', 'varchar(250)') as WebsiteUrl,
T.N.value('PrimaryServices[1]', 'varchar(250)') as PrimaryServices,
T.N.value('SecondaryServices[1]', 'varchar(250)') as SecondaryServices,
T.N.value('Description[1]', 'varchar(max)') as Description
from #XML.nodes('/root/DocInfo') as T(N)
This works fine for the single node values (CompanyName, WebsiteUrl). However, it isn't inserting the nodes with multiple values properly (like PrimaryServices and SecondaryServices - each of which may have zero to 16 nodes). How do I get these variable length multiple node values into these columns?
Thanks for any help
To get the multiple nodes as a comma separated value you can use a variant of the for xml path('') trick. Use the shredded XML (T.N) as a source in the sub-query to get the nodes you are interested in. The xQuery ... substring(text()[1]) ... part is just there to remove the extra comma and to get the comma separated value out of the XML that is created by for xml.
select
T.N.value('(CompanyName/text())[1]', 'varchar(250)') as CompanyName,
T.N.value('(WebsiteUrl/text())[1]', 'varchar(250)') as WebsiteUrl,
(
select ', '+P.N.value('text()[1]', 'varchar(max)')
from T.N.nodes('PrimaryServices') as P(N)
for xml path(''), type
).value('substring(text()[1], 2)', 'varchar(max)') as PrimaryServices,
(
select ', '+S.N.value('text()[1]', 'varchar(max)')
from T.N.nodes('SecondaryServices') as S(N)
for xml path(''), type
).value('substring(text()[1], 2)', 'varchar(max)') as SecondaryServices,
T.N.value('(Description/text())[1]', 'varchar(max)') as Description
from #XML.nodes('/root/DocInfo') as T(N)
If you want all the services in one column you can use a different xPath in the nodes part in the sub-query.
select
T.N.value('(CompanyName/text())[1]', 'varchar(250)') as CompanyName,
T.N.value('(WebsiteUrl/text())[1]', 'varchar(250)') as WebsiteUrl,
(
select ', '+P.N.value('text()[1]', 'varchar(max)')
from T.N.nodes('PrimaryServices,SecondaryServices') as P(N)
for xml path(''), type
).value('substring(text()[1], 2)', 'varchar(max)') as Services,
T.N.value('(Description/text())[1]', 'varchar(max)') as Description
from #XML.nodes('/root/DocInfo') as T(N)
I have the following XML generated from various tables in my SQL SERVER database

<AllMyData>
NOTE - all the independent elements that I am combining have the same tag name.
Thanks in advance for looking this up.

Depends on how you have it but if it is in a XML variable you can do like this.
declare #XML1 xml
declare #XML2 xml
declare #XML3 xml
set #XML1 = '<XMLData><Type>1</Type></XMLData>'
set #XML2 = '<XMLData><Type>2</Type></XMLData>'
set #XML3 = '<XMLData><Type>3</Type></XMLData>'
select #XML1, #XML2, #XML3
for xml path('AllMyData')
I can't comment but can answer so even though I think a comment is more appropriate, I'll expand on what rainabba answered above to add a bit more control. My .Net code needs to know the column name returned so I can't rely on auto-generated names but needed the very tip rainabba provided above otherwise.
This way, the xml can effectively be concatenated into a single row and the resulting column named. You could use this same approach to assign the results to an XML variable and return that from a PROC also.
SELECT (
SELECT XmlData as [*]
FROM
(
SELECT
xmlResult AS [*]
FROM
#XmlRes
WHERE
xmlResult IS NOT NULL
FOR XML PATH(''), TYPE
) as DATA(XmlData)
FOR XML PATH('')
) as [someColumnName]
If you use for xml type, you can combine the XML columns without casting them. For example:
select *
from (
select (
select 1 as Type
for xml path(''), type
)
union all
select (
select 2 as Type
for xml path(''), type
)
union all
select (
select 3 as Type
for xml path(''), type
)
) as Data(XmlData)
for xml path(''), root('AllMyData'), type
This prints:
<AllMyData>
<XmlData>
<Type>1</Type>
</XmlData>
<XmlData>
<Type>2</Type>
</XmlData>
<XmlData>
<Type>3</Type>
</XmlData>
</AllMyData>
As an addendum to Mikael Eriksson's answer - If you have a process where you need to continually add nodes and then want to group that under a single node, this is one way to do it:
declare #XML1 XML
declare #XML2 XML
declare #XML3 XML
declare #XMLSummary XML
set #XML1 = '<XMLData><Type>1</Type></XMLData>'
set #XMLSummary = (SELECT #XMLSummary, #XML1 FOR XML PATH(''))
set #XML2 = '<XMLData><Type>2</Type></XMLData>'
set #XMLSummary = (SELECT #XMLSummary, #XML2 FOR XML PATH(''))
set #XML3 = '<XMLData><Type>3</Type></XMLData>'
set #XMLSummary = (SELECT #XMLSummary, #XML3 FOR XML PATH(''))
SELECT #XMLSummary FOR XML PATH('AllMyData')
I needed to do the same but without knowing how many rows/variables were concerned and without extra schema added so here was my solution. Following this pattern, I can generate as many snippets as I want, combine them, pass them between PROCS or even return them from procs and at any point, wrap them up in containers all without modifying the data or being forced to add XML structure into my data. I use this approach with HTTP end points to provide XML Web services and with another trick that converts XML into JSON, to provide JSON WebServices.
-- SETUP A type (or use this design for a Table Variable) to temporarily store snippets into. The pattern can be repeated to pass/store snippets to build
-- larger elements and those can be further combined following the pattern.
CREATE TYPE [dbo].[XMLRes] AS TABLE(
[xmlResult] [xml] NULL
)
GO
-- Call the following as much as you like to build up all the elements you want included in the larger element
INSERT INTO #XMLRes ( xmlResult )
SELECT
(
SELECT
'foo' '#bar'
FOR XML
PATH('SomeTopLevelElement')
)
-- This is the key to "concatenating" many snippets into a larger element. At the end of this, add " ,ROOT('DocumentRoot') " to wrapp them up in another element even
-- The outer select is a time from user2503764 that controls the output column name
SELECT (
SELECT XmlData as [*]
FROM
(
SELECT
xmlResult AS [*]
FROM
#XmlRes
WHERE
xmlResult IS NOT NULL
FOR XML PATH(''), TYPE
) as DATA(XmlData)
FOR XML PATH('')
) as [someColumnName]

Please consider this simple example. I can't get the text of the state element 'red' or 'blue' Please help!!!!! this is driving me batty
DECLARE #xml XML;
SET #xml = '<capitals>
<state name="Alabama"
abbreviation="AL"
capital="Montgomery" >red</state>
<state name="Alaska"
abbreviation="AK"
capital="Juneau" >blue</state>
<state name="Arizona"
abbreviation="AZ"
capital="Phoenix" >green</state>
</capitals>';
SELECT Node.value('#name', 'varchar(100)') AS Name,
Node.value('#abbreviation', 'varchar(2)') AS Abbreviation,
Node.value('#capital', 'varchar(100)') AS Capital
FROM #xml.nodes('/capitals/state') TempXML (Node);
You just have to use the . to get the inner text of the element. You can also use text()[1] There is a really good tutorial and examples on xPath in here.
DECLARE #xml XML;
SET #xml = '<capitals>
<state name="Alabama"
abbreviation="AL"
capital="Montgomery" >red</state>
<state name="Alaska"
abbreviation="AK"
capital="Juneau" >blue</state>
<state name="Arizona"
abbreviation="AZ"
capital="Phoenix" >green</state>
</capitals>';
SELECT Node.value('#name', 'varchar(100)') AS Name,
Node.value('#abbreviation', 'varchar(2)') AS Abbreviation,
Node.value('#capital', 'varchar(100)') AS Capital,
Node.value('.', 'varchar(100)') AS Color
FROM #xml.nodes('/capitals/state') TempXML (Node);
I guess I am silly:
Node.value('.','varchar(100)') AS PoliticalDisposition
