I am trying to run a query against some xml in SQL Server 2008 and I am not getting a result. I have done some online research and came up with the following query. I played around and was able to return the root node, but I need the values from inside and there is an array of call nodes and I need values from it.
WITH XMLNAMESPACES ('http://api.myapi.com/resource' as r)
select c.value('#AgentCall','varchar(max)') as value
from mytable cl
outer apply cl.callinfoxml.nodes('//Call') as q(c)
Sample XML:
<r:ResourceList xmlns:r="http://api.myapi.com/resource" xmlns="http://api.myapi.com/data" totalResults="1">
<Call id="1123570170003">
<FromNumber>14062618272</FromNumber>
<ToNumber>14062618272</ToNumber>
<State>READY</State>
<BatchId>12827094003</BatchId>
<BroadcastId>14633834003</BroadcastId>
<ContactId>818582749003</ContactId>
<Inbound>false</Inbound>
<Created>2016-09-22T06:22:18Z</Created>
<Modified>2016-09-22T06:22:18Z</Modified>
<AgentCall>false</AgentCall>
</Call>
</r:ResourceList>
You're not paying attention to the default XML namespace in your document - you need to reference that as well. Try this code:
WITH XMLNAMESPACES (DEFAULT 'http://api.myapi.com/data',
'http://api.myapi.com/resource' as r)
SELECT
c.value('#AgentCall', 'varchar(max)') AS value
FROM
mytable cl
OUTER APPLY
cl.callinfoxml.nodes('/r:ResourceList/Call') as q(c)

I have XML coming in as the input, but I'm unclear on how I need to setup the data and statement to get the values from it. My XML is as follows:
<Keys>
<key>246</key>
<key>247</key>
<key>248</key>
</Keys>
And I want to do the following (is simplified to get my point across)
Select *
From Transaction as t
Inner Join #InputXml.nodes('Keys') as K(X)
on K.X.value('#Key', 'INT') = t.financial_transaction_grp_key
Can anyone provide how I would do that? What would my 3rd/4th line in the SQL look like?
Thanks!
From your code I assume this is SQL-Server but you added the tag [mysql]...
For your next question please keep in mind, that it is very important to know your tools (vendor and version).
Assuming T-SQL and [sql-server] (according to the provided sample code) you were close:
DECLARE #InputXml XML=
N'<Keys>
<key>246</key>
<key>247</key>
<key>248</key>
</Keys>';
DECLARE #YourTransactionTable TABLE(ID INT IDENTITY,financial_transaction_grp_key INT);
INSERT INTO #YourTransactionTable VALUES (200),(246),(247),(300);
Select t.*
From #YourTransactionTable as t
Inner Join #InputXml.nodes('/Keys/key') as K(X)
on K.X.value('text()[1]', 'INT') = t.financial_transaction_grp_key;
What was wrong:
.nodes() must go down to the repeating element, which is <key>
In .value() you are using the path #Key, which is wrong on two sides: 1) <key> is an element and not an attribute and 2) XML is strictly case-sensitive, so Key!=key.
An alternative might be this:
WHERE #InputXml.exist('/Keys/key[. cast as xs:int? = sql:column("financial_transaction_grp_key")]')=1;
Which one is faster depends on the count of rows in your source table as well as the count of keys in your XML. Just try it out.
You probably need to parse the XML to a readable format with regex.
I wrote a similar event to parse the active DB from an xmlpayload that was saved on a table. This may or may not work for you, but you should be able to at least get started.
SELECT SUBSTRING(column FROM IF(locate('<key>',column)=0,0,0+LOCATE('<key>',column))) as KEY FROM table LIMIT 1\G
I have an XML document that I'm working to build a schema for in order to bulk load these documents into a SQL Server table. The XML I'm focusing on looks like this:
<Coverage>
<CoverageCd>BI</CoverageCd>
<CoverageDesc>BI</CoverageDesc>
<Limit>
<FormatCurrencyAmt>
<Amt>30000.00</Amt>
</FormatCurrencyAmt>
<LimitAppliesToCd>PerPerson</LimitAppliesToCd>
</Limit>
<Limit>
<FormatCurrencyAmt>
<Amt>85000.00</Amt>
</FormatCurrencyAmt>
<LimitAppliesToCd>PerAcc</LimitAppliesToCd>
</Limit>
</Coverage>
<Coverage>
<CoverageCd>PD</CoverageCd>
<CoverageDesc>PD</CoverageDesc>
<Limit>
<FormatCurrencyAmt>
<Amt>50000.00</Amt>
</FormatCurrencyAmt>
<LimitAppliesToCd>Coverage</LimitAppliesToCd>
</Limit>
</Coverage>
Inside the Limit element, there's a child LimitAppliesToCd that I need to use to determine where the Amt element's value actually gets stored inside my table. Is this possible to do using the standard XML Bulk Load feature of SQL Server? Normally in XML I'd expect that the element would have an attribute containing the "PerPerson" or "PerAcc" information, but this standard we're using does not call for that.
If anyone has worked with the ACORD standard before, you might know what I'm working with here. Any help is greatly appreciated.
Don't know exactly what you are talking about, but this is a solution to get the information out of your XML.
Assumption: Your XML is already bulk-loaded into a declared variable #xml of type XML:
A CTE will pull the information out of your XML. The final query will then use PIVOT to put your data into the right column.
With a fitting table's structure the actual insert should be simple...
WITH DerivedTable AS
(
SELECT cov.value('CoverageCd[1]','varchar(max)') AS CoverageCd
,cov.value('CoverageDesc[1]','varchar(max)') AS CoverageDesc
,lim.value('(FormatCurrencyAmt/Amt)[1]','decimal(14,4)') AS Amt
,lim.value('LimitAppliesToCd[1]','varchar(max)') AS LimitAppliesToCd
FROM #xml.nodes('/root/Coverage') AS A(cov)
CROSS APPLY cov.nodes('Limit') AS B(lim)
)
SELECT p.*
FROM
(SELECT * FROM DerivedTable) AS tbl
PIVOT
(
MIN(Amt) FOR LimitAppliesToCD IN(PerPerson,PerAcc,Coverage)
) AS p
I have this query taken from the site www.SQLauthority.com:
DECLARE #MyXML XML
SET #MyXML = '<SampleXML>
<Colors>
<Color1>White</Color1>
<Color2>Blue</Color2>
<Color3>Black</Color3>

SELECT

a.b.value('Fruits[1]/Fruits4[1]','varchar(10)') AS Fruits4
FROM #MyXML.nodes('SampleXML') a(b)
I am not getting a better picture of how the nodes fetching from the xml data.
I have few queries regarding this.
what is a(b) in this?
how the structure will change if i have another node inside colors and all the existing child nodes appended to that?
ie:
<Colorss>
<Colors>
<Color1>White</Color1>
<Color2>Blue</Color2>
<Color3>Black</Color3>
<Color4 Special="Light">Green</Color4>
<Color5>Red</Color5>
</Colors>
<Colorss>
<Fruits>
<Fruits1>Apple</Fruits1>
<Fruits2>Pineapple</Fruits2>
<Fruits3>Grapes</Fruits3>
<Fruits4>Melon</Fruits4>
</Fruits>
what does it mean by a.b.value? When I mouse over it shows a is derived table. Can I check value of the table a?
Any help in this will be appreciated.
what is a(b) in this?
The call to .nodes('SampleXML') is a XQuery function which returns a pseudo table which contains one column of an XML fragment for each of the elements that this XPath expression matches - and the a(b) is the table alias (a) for that column, and b is the name of the column in that pseudo table containing the XML fragments.
what does it mean by a.b.value?
This is based on the above - a is the table alias for that temporary, inline pseudo table, b is the column name for the column in that table, and .value() is another XQuery function that will extract a single value from XML, based on the XPath expression (first argument) and it will return it as the datatype specified in the second argument.
You should check out those introductions to XQuery support in SQL Server to understand better:
Introduction to XQuery in SQL Server 2005
XQuery basics
and there are numerous other introductions and tutorials on XQuery - just search with your favorite search engine and you'll get tons of hits!
here's my stab # it:
a-refers to root;b-refers to root and child node
DECLARE #MyXML XML
SET #MyXML = '<SampleXML>
<Colors>
<Color1>White</Color1>
<Color2>Blue</Color2>
<Color3>Black</Color3>
<Color4 Special="Light">Green</Color4>
<Color5>Red
<Color6>Black44</Color6>
<Color7>Black445</Color7>
</Color5>
</Colors>
<Fruits>
<Fruits1>Apple</Fruits1>
<Fruits2>Pineapple</Fruits2>
<Fruits3>Grapes</Fruits3>
<Fruits4>Melon</Fruits4>
</Fruits>
</SampleXML>'
to get an inner child
SELECT
a.c.value('Colors1/Color11','varchar(10)') AS Color1,
a.c.value('Colors1/Color21','varchar(10)') AS Color2,
a.c.value('Colors1/Color31','varchar(10)') AS Color3,
a.c.value('Colors1/Color41/#Special','varchar(10)') AS Color4,
a.c.value('Colors1/Color51','varchar(10)') AS Color5,
a.c.value('Colors1/Color51/Color71','varchar(50)') AS Color6a,
a.c.value('Colors1/Color51/Color61','varchar(50)') AS Color6b, a.c.value('Fruits1/Fruits11','varchar(10)') AS Fruits1,
a.c.value('Fruits1/Fruits21','varchar(10)') AS Fruits2,
a.c.value('Fruits1/Fruits31','varchar(10)') AS Fruits3,
a.c.value('Fruits1/Fruits41','varchar(10)') AS Fruits4
FROM #MyXML.nodes('SampleXML') a(c)
A nodes() method invocation with the query expression /root/Color(n) would return a rowset with three rows, each containing a logical copy of the original XML document, and with the context item set to one of the nodes

GO
What I am looking for is:
erpcode securitydeposit
16622710 10000
Kindly help
You don't need ;WITH XMLNAMESPACES for this purpose since XML elements involved in the query doesn't use any namespace prefix and the XML document doesn't have defult namespace too.
Also note that XML element/attribute name are case-sensitive (f.e erpcode != ERPCode) :
SELECT
T.C.value('ERPCode[1]','numeric') as erpcode,
T.C.value('SecurityDeposit[1]','varchar(50)') AS securitydeposit
FROM ChangeEvent ce
CROSS APPLY ChangedData.nodes('MerchantInfo') AS T(C)
WHERE Ce.EntityTypeId = 2
AND T.C.value('ERPCode[1]','numeric') = 16622710

Hello I have the following xml structure within a database table column :
DECLARE #Response XML =
'<star:ShowInfo xmlns="http://www.starstandard.org/STAR/5"

<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
