I've searched on this website and internet but can't seem to get anything to work for this simple request. I just want to display the word relating to the term e.g. using the xml column below TEST will be extracted.
The xml column is as below:
<A>
<resources id="1" resourceType="Template" term="TEST" version="1" />
</A>
I've tried using the following but it returns NULLS.
select
Res.value('(/A/term)[1]','nvarchar(50)') as 'Res'
from Con
where Res is not null
Thank you in advance.
Try it like this
select
Res.value('(/A/resources/#term)[1]','nvarchar(50)') as 'Res'
from Con
where Res is not null
term is an attribute (needs a # signum) within the element <resources> below <A>. Your xpath wans't reflecting this correctly...
Try this
SELECT T.tm.value('#term[1]','nvarchar(50)') as 'Res'
FROM Con
CROSS APPLY Res.nodes('/A/resources') as T(tm)

I have the following XML:
<Main>
<ResultOutput>
<Name>TEST1</Name>
<Value>D028</Value>
</ResultOutput>
<ResultOutput>
<Name>TEST2</Name>
<Value>Accept</Value>
</ResultOutput>
<ResultOutput>
<Name>TEST3</Name>
<Value />
</ResultOutput>
</Main>
What I want is to get the value of the <value> tag in SQL.
Basically want to say get <value> where <Name> has the value of TEST1, as an example
This is what I have at the moment, but this depends on the position of the XML tag:
XMLResponse.value(Main/ResultOutput/Value)[5]', nvarchar(max)')
The best way to do this is not to put extra where .value clauses, but to do it directly in XQuery.
Use [nodename] to filter by a child node, you can even nest such predicates. text() gets you the inner text of the node:
XMLResponse.value('(/Main/ResultOutput[Name[text()="TEST1"]]/Value/text())[1]', 'nvarchar(max)')
Below is an example using the sample XML in your question. You'll need to extend this to add namespace declarations and the proper xpath expressions that may be present in your actual XML as your query attempt suggests.
SELECT ResultOutput.value('Value[1]', 'nvarchar(100)')
FROM #xml.nodes('Main/ResultOutput') AS Main(ResultOutput)
WHERE ResultOutput.value('Name[1]', 'nvarchar(100)') = N'TEST1';
I have something like the following XML in a column of a table:
<?xml version="1.0" encoding="utf-8"?>
<container>
<param name="paramA" value="valueA" />
<param name="paramB" value="valueB" />
...
</container>
I am trying to get the valueB part out of the XML via TSQL
So far I am getting the right node, but now I can not figure out how to get the attribute.
select xmlCol.query('/container/param[#name="paramB"]') from LogTable
I figure I could just add /#value to the end, but then SQL tells me attributes have to be part of a node. I can find a lot of examples for selecting the child nodes attributes, but nothing on the sibling atributes (if that is the right term).
Any help would be appreciated.
Try using the .value function instead of .query:
SELECT
xmlCol.value('(/container/param[#name="paramB"]/#value)[1]', 'varchar(50)')
FROM
LogTable
The XPath expression could potentially return a list of nodes, therefore you need to add a [1] to that potential list to tell SQL Server to use the first of those entries (and yes - that list is 1-based - not 0-based). As second parameter, you need to specify what type the value should be converted to - just guessing here.

Depending on the the actual structure of your xml, it may be useful to put a view over it to make it easier to consume using 'regular' sql eg
CREATE VIEW vwLogTable
AS
SELECT
c.p.value('#name', 'varchar(10)') name,
c.p.value('#value', 'varchar(10)') value
FROM
LogTable
CROSS APPLY x.nodes('/container/param') c(p)
GO
-- now you can get all values for paramB as...
SELECT value FROM vwLogTable WHERE name = 'paramB'
I'm trying to extract a chunk of XML (ie the whole xml of a node, not just content) using an xpath query in SQL. I can extract a single content field but am not sure how to do the above.
Say the xml is as follows
<head>
<instance>
<tag1>
<tag2>data</tag2>
<tag3>data</tag3>
</tag1>
</instance>
</head>
I would like to extract all of the xml inside tag1, and was hoping something like this would work in a SQL query:
Table.value('(/head/instance/tag1)[1]', 'varchar(max)') as "col"
Any help would be great.
Thanks
this should work:
Select Cast(Table.xmlcolumnname.query('/head/instance/tag1') as varchar(max)) 'col';
(its not checked! may contain typo..)
In my SQL 2008 database table, I have one column name AUTHOR that contains XML data. The XML is not well formed and has data like below
<Author>
<ID>172-32-1176</ID>
<LastName>White</LastName>
<FirstName>Johnson</FirstName>
<Address>
<Street>10932 Bigge Rd.</Street>
<City>Menlo Park</City>
<State>CA</State>
</Address>
</Author>
Some XML have all of above data and some have just one tag.
<ID>172-32-1176</ID>
I want to write query that returns me a column as identiry.
I tried using AUTHOR.query('data(/Author/ID)') as identity but it fails when XML does not have Author node.
Thanks,
Vijay
Have you tried something like /Author/ID|/ID ? i.e. try for the first scenario, and with no match, the second ?
(note that the | operator is a set union operator, as described here)
In case that nothing "certain" can be maintained about the XML, except that a unique ID element contains the required identity value, then the following XPath expression selects the ID element:
//ID
With xml like:
<a>
<b>
<c>1</c>
<c>2</c>
</c>3</c>
</b>
I'm trying to create an xpath expression (for a postgresql query) that will return if is a particular value and not that is all three values. What I currently have (which does not work) is:
select * from someTable where xpath ('//uim:a/text()', job, ARRAY[ ARRAY['uim','http://www.cmpy.com/uim'] ])::text[] IN (ARRAY['1','3']);
If I try with ARRAY['1'] this will not return any values but with ARRAY['1','2','3'] it will return all three.
How can I select based on a single element in a sequence?
Thanks.
If you're asking how to get the value of a 1 or more XML elements within your XML segment the easiest way is likely to simply utilize a custom SQL CLR library and XPath analysis from within it to assemble and return whatever information you desire. At least that would be my approach.
