I have a table with an XML column (xmlCol) and I am trying to query a value from it.
Here's the xml.
<criteria>
<factor name="Rivers" title="Rivers">
<value dataType="Int32" value="1743" description="Wilson0" />
</factor>
<factor name="OptionalAffProperties" title="Include properties">
<value dataType="String" value="FishingModel" description="Fishing Model" />
</factor>
</criteria>
Here is a select to get the column. select xmlCol from MyTable
I am trying to return the value 1743 to a column called RiverID.

This should work:
SELECT
xmlCol.value('(//factor[#name="Rivers"]/value/#value)[1]', 'int') As RiverID
FROM
MyTable
value() Method (xml Data Type) - SQL Server | Microsoft Docs
XQuery Language Reference (SQL Server) - SQL Server | Microsoft Docs
To get the attribute value, you can query it like so:
select xmlCol.value('(/criteria/factor/value/#value)[1]', 'int') RiverID
from MyTable
You provide the xml path to the record you are looking for: (/criteria/factor/value
And then the attribute you need: /#value)[1].

I have an XML column in a table which i am trying to parse out values from to flat table structure.
I am trying to input the XML here but stackoverflow ses it as code and when i try and format as code it still won't accept it.
I can't even get data from "Header" level.

I am not able to parse it and i have tried using examples from other threads. I am trying to not use OPENXML solution because requires DECLARE and executing the built in procedure for clearing the XML from memmory periodically. I am trying to use the OUTER APPLY solution.
Like Shugos solution in How to parse XML data in SQL server table or Query XML with nested nodes on Cross Apply.
It doesn't work.
It returns null for the timestamp column.
select
t.file_created_time
,c.value('(Timestamp)[1]','varchar(max)') as timestamp
from load.t t
OUTER APPLY t.xml_data.nodes('RequestMessage/Header') as m(c)
Please try the following solution.
Starting from SQL Server 2005 onwards, it is better to use XQuery language, based on the w3c standards, while dealing with the XML data type.
Microsoft proprietary OPENXML and its companions sp_xml_preparedocument and sp_xml_removedocument are kept just for backward compatibility with the obsolete SQL Server 2000. Their use is diminished just to very few fringe cases.
I had to comment out the following tag <!--<IntervalReadings>--> to make your XML well-formed.
XML Header fragment has a default namespace:
xmlns="http://iec.ch/TC57/2011/schema/message"
XML Payload fragment has its own two additional namespaces:
xmlns:MeterReadings="http://iec.ch/TC57/2011/MeterReadings#"
xmlns="http://iec.ch/TC57/2011/MeterReadings#"
Namespaces should be taken into account.
Check it out below.

You need to respect and include the XML namespace in your XML document in your XQuery!
<RequestMessage xmlns="http://iec.ch/TC57/2011/schema/message"
**********************************************
Try something like this:
WITH XMLNAMESPACES(DEFAULT N'http://iec.ch/TC57/2011/schema/message')
SELECT
t.id,
c.value('(Timestamp)[1]','varchar(max)') as timestamp
FROM
load.t t
CROSS APPLY
t.xml_data.nodes('RequestMessage/Header') AS m(c)
Also when trying to run this on my SQL Server, I get an error that the XML as shown is malformed.....
UPDATE:
If you need to also access bits in the Payload section - you need to also respect that XML namespace there:
<MeterReadings xmlns:MeterReadings="http://iec.ch/TC57/2011/MeterReadings#"
xmlns="http://iec.ch/TC57/2011/MeterReadings#">
***********************************************
Try this:
WITH XMLNAMESPACES(N'http://iec.ch/TC57/2011/schema/message' as hdr,
N'http://iec.ch/TC57/2011/MeterReadings#' as mr)
SELECT
t.id,
c.value('(hdr:Timestamp)[1]', 'varchar(50)') AS timestamp,
col.value('(mr:MeterReading/mr:IntervalBlocks/mr:IntervalReadings/mr:timeStamp)[1]', 'varchar(50)') AS MeterReadingsTimestamp
FROM
load.t t
CROSS APPLY
t.xml_data.nodes('/hdr:RequestMessage/hdr:Header') AS m(c)
CROSS APPLY
t.xml_data.nodes('/hdr:RequestMessage/hdr:Payload/mr:MeterReadings') AS mr(col)
I have a SQL Server database table with a column called XML that contains XML data which is structured like this:
<Item xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://test/data">
<Roots>
<Root>
<Name>Field Name</Name>
<Value>Field Value</Value>
</Root>
<Root>
<Name>Field Name</Name>
<Value>Field Value</Value>
</Root>
</Roots>
I want to use T-SQL to get the Value where Name = Total. I have tried the following but it isn't returning any data:
SELECT [XML]
FROM [BusinessAccount]
WHERE [XML].value('(/Root/Name)[13]', 'VARCHAR(MAX)') LIKE '%Total%'
If anyone could tell me where I've gone wrong?
You are missing the required WITH XMLNAMESPACES for your XML and the path is incorrect.
If you want to bring back rows where the 13th element consists of the text Total you can use the below.
WITH XMLNAMESPACES (DEFAULT 'http://test/data')
SELECT [XML]
FROM [BusinessAccount]
WHERE 1 = [XML].exist('(/Item/Roots/Root/Name)[13][text() = "Total"]')
Otherwise you can add the WITH XMLNAMESPACES to your original query and fix the path there too.
You need to specify namespaces. You can then match <Name> and <Value> pairs and extract the contents of <Value> like so:
SELECT NameNode.value('declare namespace x="http://test/data"; (../x:Value)[1]', 'varchar(100)')
FROM [BusinessAccount]
CROSS APPLY [XML].nodes('declare namespace x="http://test/data"; //x:Root/x:Name') AS n(NameNode)
WHERE NameNode.value('.', 'varchar(100)') = 'Total'

Using TSQL/XML query how do I achieve this RESULT
[phraseprefix][phrasenumber]
rx 0001
hold 0001
...
I tried the following query, but I got null values for both the columns:
DECLARE #input XML = (SELECT result_xml
FROM QM_Data_Audit.QM_Package.test_results
WHERE result_id = 2446338)
SELECT
resultset.value('(phraseprefix)[1]', 'varchar(max)') AS 'phrasenumber',
resultset.value('(phrasenumber)[1]', 'int') AS 'phrasenumber'
FROM #input.nodes('/resultset/result/result_data') AS List(resultset)
My apologies if the question is asked previously, I am new to querying XML.
Appreciate your help.
Your xml has a namespace declared so you need to provide this when querying it. In this example this can be acheived with the WITH XMLNAMESPACES statement:
DECLARE #input XML = (SELECT result_xml
FROM QM_Data_Audit.QM_Package.test_results
WHERE result_id = 2446338);
WITH XMLNAMESPACES(DEFAULT 'qm_system_resultset')
SELECT
resultset.value('(phraseprefix)[1]', 'varchar(max)') AS 'phrasenumber',
resultset.value('(phrasenumber)[1]', 'varchar(max)') AS 'phrasenumber'
FROM #input.nodes('/resultset/result/result_data') AS List(resultset)
You'll want to set the data type for phrasenumber to varchar as well to preserve the leading 0s if you need them.

This is the sample of xml in my table column;
Table name t005, column name ACTIVITYDETAIL, data type xml.
Sample of xml
<root>
<Parameter>
<Param>SearcgBy</Param>
<Value>ALL</Value>
</Parameter>
<Parameter>
<Param>SearchText</Param>
<Value>SA</Value>

Now I want output as
Param value
SearchBy ALL
SearchText SA
I tried so many ways and here is my last try.
SELECT
p.value('(./Parameter/node())[1]', 'VARCHAR(8000)') as firstName,
p.value('(./Parameter/node())[2]', 'VARCHAR(8000)') as lastName
FROM
t005
CROSS APPLY
ACTIVITYDETAIL.nodes('/root') t(p)
Please help me.
Try this
SELECT
t.p.value('Param[1]','varchar(20)') as Param,
t.p.value('Value[1]','varchar(20)') as Value
FROM T005 CROSS APPLY ACTIVITYDETAIL.nodes('/root/Parameter') t(p)
