This seems very basic, but I haven't been able to find an example that works for me, so I'd appreciate any advice.
I have a SQL Server function that determines various dates based on our fiscal year and today's date, and returns one row which looks like...
<row LastDayPrevMonth="2015-04-30T00:00:00" LastDayPrevMonthLY="2014-04-30T00:00:00" ... />
In the stored proc which calls that function, I've done...
DECLARE #X XML
SET #X = dbo.GetFiscalYearDates()
...but then I can't seem to extract the value of LastDayPrevMonth.
I've tried dozens of variations of this:
SELECT ROW.ITEM.VALUE('LastDayPrevMonth', 'VARCHAR(30)')[1] AS Foo FROM #x.nodes('row/item') ... sometimes with an "AS Bar" at the end...
That particular syntax gives the error "incorrect syntax near the keywork 'as'", but any tweaks I do don't help.
Thanks for your assistance, dudes!
declare #doc xml
select #doc= '
<root>
<row LastDayPrevMonth="2015-04-30T00:00:00" LastDayPrevMonthLY="2014-04-30T00:00:00" />
</root>
'
SELECT
LastDayPrevMonth = Y.i.value('(#LastDayPrevMonth)[1]', 'datetime')
, LastDayPrevMonthLY = Y.i.value('#LastDayPrevMonthLY[1]', 'datetime')
FROM
#doc.nodes('root/row') AS Y(i)

Im working on a script that will allow me to save the xml data in a table. This will be used to compare with other tables which also contains an xml data.
I've been successful so far for simple node tags, but have encountered an issue when trying to store the data from a list.
The XML data looks like this:Sample XML Data
And my query is this:
XML Query display
I am able to get the 'TypeCode' as the main node but for the value, it's always showing blank. I'm not sure how to handle the list in XML.
I'm thinking as long as I can save the data
''
'' as text in the Value column, then I can find another way to parse it and display it in a nicer way as another query.
Any help is appreciated :D Thanks!
For your next question: Please do not post pictures. I had to type this in... Please provide consumable data, best as a stand-alone example to reproduce your issue.
DECLARE #xml XML=
'<Codes>
<TypeCodes type="list">
<item key="A" text="A1"/>
<item key="C" text="C1"/>
</TypeCodes>
</Codes>';
--the Xml "as is"
SELECT #xml;
--fetch one value with XQuery
SELECT #xml.value('(/Codes/TypeCodes/item[#key="A"]/#text)[1]','varchar(10)');
--fetch all items as list
SELECT #xml.value('(/Codes/TypeCodes/#type)[1]','varchar(10)') AS TypeCode_type
,i.value('#key','varchar(10)') AS item_key
,i.value('#text','varchar(10)') AS item_text
FROM #xml.nodes('/Codes/TypeCodes/item') A(i);

Good day,
SQL Server include special data type XML which is what you should use in order to store your XML data.
declare #MyXML XML = '
<codes>
<Type>
<Item key="1" />
</Type>
</codes>
'
select #MyXML
Here is example of using table:
DROP TABLE IF eXISTS T;
CREATE TABLE T(MyXML XML)
GO
INSERT T(MyXML) values ('
<codes>
<Type>
<Item key="1" />
</Type>
</codes>
')
SELECT * FROM T
GO

XML Data Type and Columns (SQL Server)
I want to set a processing instruction to include a stylesheet on top of an XML:
The same issue was with the xml-declaration (e.g. <?xml version="1.0" encoding="utf-8"?>)
Desired result:
<?xml-stylesheet type="text/xsl" href="stylesheet.xsl"?>
<TestPath>
<Test>Test</Test>
<SomeMore>SomeMore</SomeMore>
</TestPath>
My research brought me to node test syntax and processing-instruction().
This
SELECT 'type="text/xsl" href="stylesheet.xsl"' AS [processing-instruction(xml-stylesheet)]
,'Test' AS Test
,'SomeMore' AS SomeMore
FOR XML PATH('TestPath')
produces this:
<TestPath>
<?xml-stylesheet type="text/xsl" href="stylesheet.xsl"?>
<Test>Test</Test>
<SomeMore>SomeMore</SomeMore>
</TestPath>
All hints I found tell me to convert the XML to VARCHAR, concatenate it "manually" and convert it back to XML. But this is - how to say - ugly?
This works obviously:
SELECT CAST(
'<?xml-stylesheet type="text/xsl" href="stylesheet.xsl"?>
<TestPath>
<Test>Test</Test>
<SomeMore>SomeMore</SomeMore>
</TestPath>' AS XML);
Is there a chance to solve this?
There is another way, which will need two steps but don't need you to treat the XML as string anywhere in the process :
declare #result XML =
(
SELECT
'Test' AS Test,
'SomeMore' AS SomeMore
FOR XML PATH('TestPath')
)
set #result.modify('
insert <?xml-stylesheet type="text/xsl" href="stylesheet.xsl"?>
before /*[1]
')
Sqlfiddle Demo
The XQuery expression passed to modify() function tells SQL Server to insert the processing instruction node before the root element of the XML.
UPDATE :
Found another alternative based on the following thread : Merge the two xml fragments into one? . I personally prefer this way :
SELECT CONVERT(XML, '<?xml-stylesheet type="text/xsl" href="stylesheet.xsl"?>'),
(
SELECT
'Test' AS Test,
'SomeMore' AS SomeMore
FOR XML PATH('TestPath')
)
FOR XML PATH('')

As it came out, har07's great answer does not work with an XML-declaration. The only way I could find was this:
DECLARE #ExistingXML XML=
(
SELECT
'Test' AS Test,
'SomeMore' AS SomeMore
FOR XML PATH('TestPath'),TYPE
);
DECLARE #XmlWithDeclaration NVARCHAR(MAX)=
(
SELECT N'<?xml version="1.0" encoding="UTF-8"?>'
+
CAST(#ExistingXml AS NVARCHAR(MAX))
);
SELECT #XmlWithDeclaration;
You must stay in the string line after this step, any conversion to real XML will either give an error (when the encoding is other then UTF-16) or will omit this xml-declaration.
Hello I have the following xml structure within a database table column :
DECLARE #Response XML =
'<star:ShowInfo xmlns="http://www.starstandard.org/STAR/5"
xmlns:ns2="http://www.openapplications.org/oagis/9"
xmlns:star="http://www.starstandard.org/STAR/5"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" releaseID="5.1.5"
xsi:noNamespaceSchemaLocation="">
<ShowDataArea>
<ServiceInfo>
<SVPlanInfo>
<AKStatus>
<Code>Error</Code>
<STText xsi:type="ns2:TextType">E12143 - Please fetch me from this xml </STText>
</AKStatus>
</SVPlanInfo>
</ServiceInfo>
</ShowDataArea></star:ShowInfo>'
In the above xml I need to fetch the STText value which is
E12143 - Please fetch me from this xml . Can anyone point me on how I can do it ?
I tried the following but it doesnt seem to work :
;WITH XMLNAMESPACES ('http://www.w3.org/2001/XMLSchema' as xsd,
'http://www.w3.org/2001/XMLSchema-instance' as xsi)
SELECT #Response.value('(/xsd:Response)[1]','nvarchar(500)') as ExceptionMessage
What a pain.
remove:
xmlns="http://www.starstandard.org/STAR/5"
It is not a sql issue, but rather namespace-getting-confused issue.
Its heplful totake SQL out the equation sometimes, by testing some place like

I have a table with an ntext type column that holds xml. I have tried to apply many examples of how to pull the value for the company's name from the xml for a particular node, but continue to get a syntax error. Below is what I've done, except substituted my select statement for the actual xml output
DECLARE #companyxml xml
SET #companyxml =
'<Home>

<logoImg>1110</logoImg>
<pageHeader></pageHeader>
</Home>'
SELECT c.value ('companyName','varchar(1000)') AS companyname
FROM #companyxml.nodes('/Home') AS c
For some reason, the select c.value statement has a syntax problem that I can't figure out. On hover in SSMS, it says 'cannot find either column "c" or the user-defined function or aggregate "c.value", or the name is ambiguous.'
Any help on the syntax would be greatly appreciated.
try this
DECLARE #companyxml xml
SET #companyxml =

DECLARE #Result AS varchar(50)
SET #result = #companyxml.value('(/Home/companyName/text())[1]','varchar(50)')
SELECT #result
Update: giving a much more thorough example.
The first two solutions offered were right along the lines of what I was trying to say not to do. I can't know location, it needs to be able to look at the whole document tree. So a solution along these lines, with /Books/ specified as the context will not work:
SELECT x.query('.') FROM #xml.nodes('/Books/*[not(#ID) or #ID = 5]') x1(x)
Original question with better example:
Using SQL Server 2005's XQuery implementation I need to select all nodes in an XML document, just once each and keeping their original structure, but only if they are missing a particular attribute, or that attribute has a specific value (passed in by parameter). The query also has to work on the whole XML document (descendant-or-self axis) rather than selecting at a predefined depth.
That is to say, each individual node will appear in the resultant document only if it and every one of its ancestors are missing the attribute, or have the attribute with a single specific value.
For example:
If this were the XML:
DECLARE #Xml XML
SET #Xml =
N'
<Library>
<Novels>
<Novel category="1">Novel1</Novel>
<Novel category="2">Novel2</Novel>
<Novel>Novel3</Novel>
<Novel category="4">Novel4</Novel>
</Novels>
<Encyclopedias>
<Encyclopedia>
<Volume>A-F</Volume>
<Volume category="2">G-L</Volume>
<Volume category="3">M-S</Volume>
<Volume category="4">T-Z</Volume>
</Encyclopedia>
</Encyclopedias>
<Dictionaries category="1">
<Dictionary>Webster</Dictionary>
<Dictionary>Oxford</Dictionary>
</Dictionaries>
</Library>
'
A parameter of 1 for category would result in this:
<Library>
<Novels>
<Novel category="1">Novel1</Novel>
<Novel>Novel3</Novel>
</Novels>
<Encyclopedias>
<Encyclopedia>
<Volume>A-F</Volume>
</Encyclopedia>
</Encyclopedias>
<Dictionaries category="1">
<Dictionary>Webster</Dictionary>
<Dictionary>Oxford</Dictionary>
</Dictionaries>
</Library>
A parameter of 2 for category would result in this:
<Library>
<Novels>
<Novel category="2">Novel2</Novel>
<Novel>Novel3</Novel>
</Novels>
<Encyclopedias>
<Encyclopedia>
<Volume>A-F</Volume>
<Volume category="2">G-L</Volume>
</Encyclopedia>
</Encyclopedias>
</Library>
I know XSLT is perfectly suited for this job, but it's not an option. We have to accomplish this entirely in SQL Server 2005. Any implementations not using XQuery are fine too, as long as it can be done entirely in T-SQL.
It's not clear for me from your example what you're actually trying to achieve. Do you want to return a new XML with all the nodes stripped out except those that fulfill the condition? If yes, then this looks like the job for an XSLT transform which I don't think it's built-in in MSSQL 2005 (can be added as a UDF: http://www.topxml.com/rbnews/SQLXML/re-23872_Performing-XSLT-Transforms-on-XML-Data-Stored-in-SQL-Server-2005.aspx).
If you just need to return the list of nodes then you can use this expression:
//Book[not(#ID) or #ID = 5]
but I get the impression that it's not what you need. It would help if you can provide a clearer example.
Edit: This example is indeed more clear. The best that I could find is this:
SET #Xml.modify('delete(//*[#category!=1])')
SELECT #Xml
The idea is to delete from the XML all the nodes that you don't need, so you remain with the original structure and the needed nodes. I tested with your two examples and it produced the wanted result.
However modify has some restrictions - it seems you can't use it in a select statement, it has to modify data in place. If you need to return such data with a select you could use a temporary table in which to copy the original data and then update that table. Something like this:
INSERT INTO #temp VALUES(#Xml)
UPDATE #temp SET data.modify('delete(//*[#category!=2])')
Hope that helps.
The question is not really clear, but is this what you're looking for?
DECLARE #Xml AS XML
SET #Xml =
N'
