I'm trying to get the value from the property Success but I can't, I don't know where I'm wrong.
This is my code
DECLARE #Response VARCHAR(8000) = '<?xml version="1.0" encoding="utf-8"?>
<Result xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/">
<Success>true</Success>
</Result>'
DECLARE #xml TABLE (
Content XML
)
INSERT INTO #xml
SELECT CAST(#Response AS XML)
SELECT
Content.value('(/Result/Success)[1]', 'BIT')
FROM #xml
The property Success is bool type
I'm trying with different scope types (nvarchar, varchar, bit, etc..)
This is what I expecting
or
Please try the following solution.
Notable points:
It is always better to use XML data type instead of the VARCHAR(..) for XML
data.
All XML elements are bound to the default namespace even if we don't
see it explicitly. That's why we need to specify it via
XMLNAMESPACES clause.
It is always better to use text() in the XPath expressions for XML
elements for performance reasons. Peculiarity of the MS SQL Server.
It is possible to omit XML prolog declaration completely. SQL Server
doesn't store it.
SQL
DECLARE #Response XML = '<?xml version="1.0" encoding="utf-8"?>
<Result xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/">
<Success>true</Success>
</Result>';
DECLARE #xml TABLE (Content XML);
INSERT INTO #xml
SELECT #Response;
;WITH XMLNAMESPACES (DEFAULT 'http://tempuri.org/')
SELECT result = Content.value('(/Result/Success/text())[1]', 'BIT')
FROM #xml;
Output

I'm trying to parse the XML data coming from the SQL Server. But although I tried many ways, I could not succeed.
When I run the script it does not give an error but returns a not record
DECLARE #xmlData XML
SET #xmlData = '<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<S:Fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope">
<faultcode>S:VersionMismatch</faultcode>
<faultstring>Couldnt create SOAP message. Expecting Envelope in namespace http://schemas.xmlsoap.org/soap/envelope/, but got null </faultstring>
</S:Fault>
</S:Body>
</S:Envelope>
'
SET #xmlData = (SELECT #xmlData.query('declare default element namespace "http://schemas.xmlsoap.org/soap/envelope/";
/Envelope/Body'))
SELECT #xmlData
SELECT b.value('(./Fault/faultcode/text())[1]', 'Varchar(50)') AS [Name]
FROM #xmlData.nodes('/Body') AS a (b)
Using WITH XMLNAMESPACES:
;WITH XMLNAMESPACES('http://schemas.xmlsoap.org/soap/envelope/' AS S)
SELECT b.value('(./S:Fault/faultcode/text())[1]', 'Varchar(50)') AS [Name]
FROM #xmlData.nodes('//S:Body') AS a (b);

I am trying to get a (for right now) simple XML to feed into a SQL Server table.
The XML is:
<?xml version="1.0" encoding="utf-8"?>
<ArrayOfSafeEODBalance xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SafeEODBalance>
<Lane>1</Lane>
<PouchId>06292019053041001</PouchId>
<BusinessDay>6/29/2019</BusinessDay>
<BusinessStartingTime>6/29/2019 5:36:58 AM</BusinessStartingTime>
<BusinessEndingTime>6/30/2019 12:15:55 AM</BusinessEndingTime>
<StartingBalance>0.0000</StartingBalance>
<EndingBalance>8</EndingBalance>
</SafeEODBalance>
<SafeEODBalance>
<Lane>2</Lane>
<PouchId>06292019053042002</PouchId>
<BusinessDay>6/29/2019</BusinessDay>
<BusinessStartingTime>6/29/2019 5:36:58 AM</BusinessStartingTime>
<BusinessEndingTime>6/30/2019 12:15:55 AM</BusinessEndingTime>
<StartingBalance>100.0000</StartingBalance>
<EndingBalance>2</EndingBalance>
</SafeEODBalance>
</ArrayOfSafeEODBalance>
And saved to C:\Users\cj\Documents\EodBalance.xml
I have set up the SQL Server table [dbo].[EndofDay] which has the columns of each of these exactly:
Here is the query I am trying:
INSERT INTO [dbo].[EndofDay] ([PouchID], [Lane], [BusinessDay], BusinessStartingTime, BusinessEndingTime, [StartingBalance], [EndingBalance])
SELECT
MY_XML.SafeEODBalance.query('PouchId').value('.', 'VARCHAR(25)'),
MY_XML.SafeEODBalance.query('Lane').value('.', 'NCHAR(2)'),
MY_XML.SafeEODBalance.query('BusinessDay').value('.', 'DATE'),
MY_XML.SafeEODBalance.query('BusinessStartingTime').value('.', 'DATETIME'),
MY_XML.SafeEODBalance.query('BusinessEndingTime').value('.', 'DATETIME'),
MY_XML.SafeEODBalance.query('StartingBalance').value('.', 'NCHAR(10)'),
MY_XML.SafeEODBalance.query('EndingBalance').value('.', 'NCHAR(10)')
FROM
(SELECT CAST(MY_XML AS XML)
FROM OPENROWSET(BULK 'C:\Users\cj\Documents\EodBalance.xml',SINGLE_BLOB) AS T(MY_XML)) AS T(MY_XML)
CROSS APPLY MY_XML.nodes('SafeEODBalance/SafeEODBalances') AS MY_XML (SafeEODBalance);
When I run this I get:
(0 rows affected)
Completion time: 2019-08-29T16:07:12.3361442-04:00
Which obviously should feed two lines into this, but it is giving nothing in the table.
Here is adjusted working SQL. Just uncomment the INSERT lines when you are ready.
SQL
WITH XmlFile (xmlData) AS
(
SELECT CAST(BulkColumn AS XML)
FROM OPENROWSET(BULK 'C:\Users\cj\Documents\EodBalance.xml', SINGLE_BLOB) AS x
)
--INSERT INTO [dbo].[EndofDay]
--([PouchID], [Lane], [BusinessDay], BusinessStartingTime, BusinessEndingTime, [StartingBalance], [EndingBalance])
SELECT c.value('(PouchId/text())[1]', 'VARCHAR(25)') AS [PouchId]
, c.value('(Lane/text())[1]', 'NCHAR(2)') AS [Lane]
, c.value('(BusinessDay/text())[1]', 'DATE') AS [BusinessDay]
, c.value('(BusinessStartingTime)[1]', 'datetime') AS [BusinessStartingTime]
, c.value('(BusinessEndingTime/text())[1]', 'datetime') AS [BusinessEndingTime]
, c.value('(StartingBalance/text())[1]', 'MONEY') AS [StartingBalance]
, c.value('(EndingBalance/text())[1]', 'MONEY') AS [EndingBalance]
FROM XmlFile CROSS APPLY xmlData.nodes('/ArrayOfSafeEODBalance/SafeEODBalance') AS t(c);

Here is a slightly different approach, using a variable to store the XML from OPENROWSET and the stored procedure sp_xml_preparedocument to convert it into an XML document.
Once in XML document form it can be queried using OPENXML(). This has the possible advantage that if you have a large or complex XML structure from which you wish to make several extracts, you can re-use the XML document repeatedly without having to reload the original XML file.
Be sure to remove the XML document using sp_xml_removedocument when you have finished with it to free up the server cache.
-- Load the XML file and convert it to an XML document
DECLARE #XML AS XML, #hXML AS INT;
SELECT #XML = CONVERT(XML, x.BulkColumn)
FROM OPENROWSET(BULK 'C:\Users\cj\Documents\EodBalance.xml\EodBalance.xml', SINGLE_BLOB) AS x;
EXEC sp_xml_preparedocument #hXML OUTPUT, #XML
-- Select data from the XML document
SELECT Lane, PouchID, BusinessDay, BusinessStartingTime, BusinessEndingTime, StartingBalance, EndingBalance
FROM OPENXML(#hXML, 'ArrayOfSafeEODBalance/SafeEODBalance') WITH
(
Lane [varchar](2) 'Lane',
PouchId [varchar](50) 'PouchId',
BusinessDay [date] 'BusinessDay',
BusinessStartingTime [datetime] 'BusinessStartingTime',
BusinessEndingTime [datetime] 'BusinessEndingTime',
StartingBalance [varchar](50) 'StartingBalance',
EndingBalance [varchar](50) 'EndingBalance'
);
-- Remove the XML document from the cache
EXEC sp_xml_removedocument #hXML;
I have a database table which is structured as shown below :
TransactionId Product ErrorXML(stored as varchar)
The ErrorXML has the structure below :
<?xml version="1.0" encoding="utf-16"?>
<GetResponse
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Error>
<ErrorCode>1809</ErrorCode>
<Description>Could not generate transaction.</Description>
</Error>
<Success>false</Success>
<ContractNumber />
</GetResponse>
I would like to write a query to extract the ErrorCode element and ErrorDescription element for each of the Errorxml row .
Is there a way I can do it ?
I did some research and tried writing a query something like this and it wouldnt work , gives out a null:
select CONVERT(XML,CONVERT(NVARCHAR(max),ErrorXML)).value('(/GetResponse/Error/Description)[1]','nvarchar(100)') as ErrorDescription
from ErrorLog E
Here's a working SQL Fiddle
The Output
ErrorCode ErrorDescription
1809 Could not generate transaction.
2119 Credit Card Overlimit.Payment Failed.
The SQL
See the SQL fiddle for why we have to use a TABLE variable due to your data being in VARCHAR and not XML datatype.
--SELECT * FROM Transactions
DECLARE #ErrorDataTable TABLE
(
ErrorXml XML NOT NULL,
ErrorCode NVARCHAR(50) NULL,
ErrorDescription NVARCHAR(200) NULL
)
INSERT
INTO #ErrorDataTable(ErrorXml)
SELECT
CONVERT(XML,CONVERT(NVARCHAR(max),T.ErrorXML))
FROM Transactions T
-- SELECT * FROM #ErrorDataTable
SELECT
T.c.value('ErrorCode[1]', 'nvarchar(50)') as ErrorCode
, T.c.value('Description[1]', 'nvarchar(200)') as ErrorDescription
FROM #ErrorDataTable e
OUTER APPLY e.ErrorXml.nodes('/GetResponse/Error') T(c);
Previous Answer (deprecated)
Following Works. I'll try to put a SQLFiddle together.
DECLARE #ErrorXML as VARCHAR(MAX);
DECLARE #x as XML;
SET #ErrorXML ='<?xml version="1.0" encoding="utf-16"?>
<GetResponse
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Error>
<ErrorCode>1809</ErrorCode>
<Description>Could not generate transaction.</Description>
</Error>
<Success>false</Success>
<ContractNumber />
</GetResponse>';
SET #x = CONVERT(XML,CONVERT(NVARCHAR(max),#ErrorXML))
SELECT
T.c.value('ErrorCode[1]', 'nvarchar(50)') as ErrorCode
, T.c.value('Description[1]', 'nvarchar(200)') as ErrorDescription
FROM #x.nodes('/GetResponse/Error') T(c);
RESULTS:
ErrorCode ErrorDescription
1809 Could not generate transaction.
I have declared a #xmldata as xml. How to read it? I tried
declare #xmldata as xml
set #xmldata = <root><row ename='abc' eid='1'/></root>
SELECT #XMLDATA
but it returned an error. I want to fetch eid column from the above xml type.
Try this:
declare #xmldata as xml
set #xmldata = '<root><row ename="abc" eid="1"/></root>'
SELECT
#xmldata.value('(/root/row/#eid)[1]', 'int') AS 'EID'
Update: if you need to select from your table and extract something from the XML column, use this approach:
SELECT
tbl.ID,
tbl.XmlColumn.value('(/root/row/#ename)[1]', 'varchar(25)') AS 'EName'
FROM
dbo.YourTable tbl
WHERE
(...some condition here...)
