I have a bunch of rows in a database that all contain an element that looks like the following
<ModuleData ModuleFieldGU="4dcdde21-40c6-4d1a-9fe1-1841935d3a68">
<DateTime>0001-01-01T00:00:00</DateTime>
<Boolean>false</Boolean>
<Int>0</Int>
<Varchar>Test District</Varchar>
<GUID>00000000-0000-0000-0000-000000000000</GUID>
<Modified>true</Modified>
</ModuleData>
I need to look across all of these and match where the varchar element/node is set to a certain value.
I've tried both of the followuing, and neither seem to be working for me
SELECT
Data.Element.value('(#Varchar)[1]', 'varchar(255)') as UserEmail
FROM
ModuleData
CROSS APPLY
XML_DATA.nodes('/ModuleData') AS Data(Element)
WHERE
Data.Element.value('(#Varchar)[1]', 'varchar(255)') = #UserEmail
and
SELECT
CAST(XML_DATA.query('data(/ModuleData[#Varchar])') as varchar(255)) as UserEmail
FROM
ModuleData
WHERE
XML_DATA.exist('/ModuleData[#Varchar = sql:variable("#UserEmail")]') = 1
but it isn't working. I'm not really up to speed with the finer points of using XQuery to get data out of XML. Can anyone point me in the correct direction?
The correct XPath should be:
/ModuleData/Varchar
Because it's an element, not an attribute.

I am trying to get the correct info from an XML data type into regular scalar variables based on conditions, however I am having trouble getting the correct info back.
Here is the XML I am searching through:
<Loop2420>
<NM1>
<F98_1>PW</F98_1>
<F1065>2</F1065>
</NM1>
<N3>
<F166>81715 DOCTOR CARRE</F166>
</N3>
<N4>
<F19>INDIO</F19>
<F156>CA</F156>
<F116>92201</F116>
</N4>
</Loop2420>
<Loop2420>
<NM1>
<F98_1>45</F98_1>
<F1065>2</F1065>
</NM1>
<N3>
<F166>51250 MECCA AVE</F166>
</N3>
<N4>
<F19>COACHELLA</F19>
<F156>CA</F156>
<F116>92236</F116>
</N4>
</Loop2420>
Basically I need to get the numbers from <'F116'> but only if <'F98_1'> is equal to 'PW'.
I have tried:
declare #zip varchar(30)
select #zip = T.value('(F116)[1]','varchar(30)')
from #TransactionXML.nodes('/Loop2420/N4') Trans(T)
where T.value('(/Loop2420/NM1/F98_1)[1]','varchar(30)') = 'PW'
But that sometimes returns the value from <'F116'> even if <'F98_1'> is equal to '45'.
Any suggestions? Thanks.
Put the test in the XQuery itself and clamp it to the node you're checking:
SELECT #zip = T.value('(N4/F116)[1]', 'varchar(30)')
FROM #TransactionXML.nodes('/Loop2420') Trans(T)
WHERE T.exist('NM1/F98_1[text()="PW"]') = 1
If PW is not a static value, use the sql:variable() or sql:column() function to incorporate it in the query.
I have following XML :

I am trying to get the value MPValue2 , from the XML.
I tried with following:
Select `#xml.value('(/ProductionSchedule/inp2:ProductionRequest/inp2:SegmentRequirement/inp2:MaterialProducedRequirement/inp2:MaterialProducedRequirementProperty)[1]','nvarchar(255)')`
Your select is OK, but you must consider/declare the namespaces:
WITH XMLNAMESPACES(DEFAULT 'http://www.wbf.org/xml/B2MML-V0401'
,'http://www.wbf.org/xml/B2MML-V0401' AS inp2)
Select #xml.value('(/ProductionSchedule/inp2:ProductionRequest/inp2:SegmentRequirement/inp2:MaterialProducedRequirement/inp2:MaterialProducedRequirementProperty)[1]','nvarchar(255)')
This works too (wildcard) but it's better to be as specific as possible:
Select #xml.value('(/*:ProductionSchedule/*:ProductionRequest/*:SegmentRequirement/*:MaterialProducedRequirement/*:MaterialProducedRequirementProperty)[1]','nvarchar(255)')
The fast and lazy would work too :-) but not fast in terms of performance...
Select #xml.value('(//*:MaterialProducedRequirementProperty)[1]','nvarchar(255)')
UPDATE
This is the query to get all your Properties:
WITH XMLNAMESPACES(DEFAULT 'http://www.wbf.org/xml/B2MML-V0401'
,'http://www.wbf.org/xml/B2MML-V0401' AS inp2)
SELECT prop.value('(inp2:ID)[1]','nvarchar(100)') AS Property
FROM #xml.nodes('/ProductionSchedule/inp2:ProductionRequest/inp2:SegmentRequirement/inp2:MaterialProducedRequirement/inp2:MaterialProducedRequirementProperty') AS A(prop)
The result
Property
--------
ERPWOStatus
ROUTING
MPValue2
UPDATE 2: Use the ID as filter in XQuery
See how I added the filter at the end of the XPath in .nodes().
Nodes will return all sub-elements row-wise. The filter will reduce the resultset to one single row (if inp2:ID is unique!) and then read the Value/ValueString.
I let the namespace declaration for DEFAULT and inp2. But, as #Serf pointed out correctly, both URLs are equal. It would be enough to declare only the DEFAULT and query without any namespace-prefixes...
DECLARE #TheID NVARCHAR(100)='MPValue2';
WITH XMLNAMESPACES(DEFAULT 'http://www.wbf.org/xml/B2MML-V0401'
,'http://www.wbf.org/xml/B2MML-V0401' AS inp2)
SELECT prop.value('(inp2:Value/inp2:ValueString)[1]','nvarchar(100)') AS Property
FROM #xml.nodes('/ProductionSchedule/inp2:ProductionRequest/inp2:SegmentRequirement/inp2:MaterialProducedRequirement/inp2:MaterialProducedRequirementProperty[inp2:ID=sql:variable("#TheID")]') AS A(prop)
This is a unique problem..I think. So my goal is to input a variable and get a row from my column. Let me explain a little with the code im doing.
SELECT
pref.query('Database/text()') as PersonSkills,
pref.query('FillQuery/text()') as PersonSkills,
pref.query('TabText/text()') as PersonSkills,
pref.query('TooltipText/text()') as PersonSkills
FROM table CROSS APPLY
Tag.nodes('/Root/Configuration/TaskSelectorControl/QueueSelector') AS People(pref)
this works fine. However what I need to do is pass in the last part, the queue selector as a variables.
DECLARE #Xml XML
DECLARE #AttributeName VARCHAR(MAX) = 'QueueSelector'
SELECT
pref.query('Database/text()') as PersonSkills,
pref.query('FillQuery/text()') as PersonSkills,
pref.query('TabText/text()') as PersonSkills,
pref.query('TooltipText/text()') as PersonSkills
FROM table CROSS APPLY
Tag.nodes('/Root/Configuration/TaskSelectorControl[#Name=sql:variable("#AttributeName")]
') AS People(pref)
this doesnt work, any ideas why?
Well, I kinda lied. the bottom works, however it returns an empty dataset
/Root/Configuration/TaskSelectorControl/QueueSelector
is not equivalent to:
/Root/Configuration/TaskSelectorControl[#Name='QueueSelector']
The above XPath selects <TaskSelectorControl Name="QueueSelector">, not <QueueSelector> children of <TaskSelectorControl>.
You could either do this in XPath:
/Root/Configuration/TaskSelectorControl/*[local-name(.)=sql:variable("#AttributeName")]
Or it might be simpler to concat prior to evaluating:
'/Root/Configuration/TaskSelectorControl/' + #AttributeName
My final goal is I want to get plid and portletId that can be display my article(or entry with any type if it is possible).
I have sql query that return me any portlet availble for display my article.
But when I have to use dynamicQuery to get the same results, I get problem with xPath and array comparison, please help!
SELECT * FROM portletpreferences pr
WHERE pr.preferences != '<portlet-preferences />' AND pr.ownerid = 0 AND pr.portletid ilike '%_INSTANCE_%' AND pr.plid IN(
SELECT layout.plid FROM layout
WHERE layout.type_ = 'portlet' AND layout.groupid = 19 AND layout.hidden_ is false)
AND pr.portletpreferencesid IN (
SELECT pr.portletpreferencesid FROM portletpreferences pr
WHERE 'true' = ANY(xpath('//preference[name="anyAssetType"]/value/text()', XMLPARSE(DOCUMENT pr.preferences))::text[])
OR (SELECT (array(SELECT id_ FROM journalstructure))::text[]) && xpath('//preference[name="classTypeIds"]/value/text()', XMLPARSE(DOCUMENT pr.preferences))::text[] )
If you are bent upon using this same query, then use this query directly with Custom-SQL in liferay by creating custom-finders instead of using DynamicQuery. That would give you a lot of flexibility in using any type of SQL query directly.
I don't think this query can be converted to DynamicQuery, but if you do manage to convert it then please do post it here :-)
DynamicQuery is very powerful, see e.g. my answer how to find layouts with specific JournalArticles. I think your requirement is similar to this one:
Liferay: How to find all Layouts with the specific JournalArticle in AssetPublisher portlets?
We have a source XML file that has an address node, and each node is supposed to have a zip_code node beneath in order to validate. We received a file that failed the schema validation because at least one node was missing it's zip_code (there were several thousand addresses in the file).
We need to find the elements that do not have a zip code, so we can repair the file and send an audit report to the source.
--declare #x xml = bulkcolumn from openrowset(bulk 'x:\file.xml',single_blob) as s
declare #x xml = N'<addresses>
<address><external_address_id>1</external_address_id><zip_code>53207</zip_code></address>
<address><external_address_id>2</external_address_id></address>
</addresses>'
declare #t xml = (
select #x.query('for $a in .//address
return
if ($a/zip_code)
then <external_address_id />
else $a/external_address_id')
)
select x.AddressID.value('.', 'int') AddressID
from #t.nodes('./external_address_id') x(AddressID)
where x.AddressID.value('.', 'int') > 0
GO
Really, it's the where clause that bugs me. I feel like I'm depending on a cast for a null value to 0, and it works, but I'm not really sure that it should. I tried a few variations with the .exist function, but I couldn't get the correct result.
If you just want to ensure that you are selecting address elements that have a zip_code element, then adjust your XPATH to include that criteria in a predicate filter:
/addresses/address[zip_code]
If you also want to ensure that the zip_code element also has a value, use a predicate filter for the zip_node to select those that have text() nodes:
/addresses/address[zip_code[text()]]
EDIT:
Actually, I'm looking for the
opposite. I need to identify the nodes
that don't have a zip, so we can
manually correct the source data.
So, if you want to identify all of the address elements that do not have a zip_code, you can specify it in the XPATH like this:
/addresses/address[not(zip_code)]
If you just want to locate those nodes that are missing their <zip_code> element, you could use something like this:
SELECT
ADRS.ADR.value('(external_address_id)[1]', 'int') as 'ExtAdrID'
FROM
#x.nodes('/addresses/address') as ADRS(ADR)
WHERE
ADRS.ADR.exist('zip_code') = 0
It uses the built-in .exist() method in XQuery to check the existence of a subnode inside an XML node.
