i am looking to parse the XML string using SQL .I like to have the data in separate columns.could some one please help?.
The string:
<item id="1" value="0"></item><item id="2" value="14"></item><item id="0" value="0"></item>
This is how you can do it in SQL Server (e.g., v2008):
create table #temp (xml_data xml)
insert into #temp values ('<item id="1" value="0"></item><item id="2" value="14"></item><item id="0" value="0"></item>')
select C.value('#id', 'int') as [id]
,C.value('#value', 'int') as [value]
from #temp cross apply
#temp.xml_data.nodes('item') as X(C)
drop table #temp
Which returns:
id value
----------- -----------
1 0
2 14
0 0
what is simple way to produce output concatenated into single column for all Parameter values in sample below, this xml doesn't have an ns in it and I'm using SQL Server 2012.
I try to get this output, below snippet with xml sample produce 3 columns, and I'd like to make 1.
100 | Param1
,Param22
,Param3322
XML & code:
DECLARE #xml XML = '<Parameters>
<Parameter>
<Name>Param1</Name>
</Parameter>
<Parameter>
<Name>Param22</Name>
</Parameter>
<Parameter>
<Name>Param3322</Name>
</Parameter> </Parameters> '
SELECT 100 id
,#XML xmlinfo
INTO #t -- drop table #t -- select * from #t
DECLARE #xml XML = (
SELECT xmlinfo
FROM #t
)
SELECT (
SELECT ID
FROM #t
) AS ID
,X.STockData.query('Name[1]').value('.', 'Varchar(10)') AS 'Parameter'
---CONCAT(X.STockData.query('Name[1]').value('.','Varchar(10)'),X.STockData.query('Name[2]').value('.','Varchar(10)')) AS 'Parameter'
FROM #xml.nodes('Parameters/Parameter') AS X(StockData)
You can use XQuery for loop to construct comma-separated value from XML field, for example :
SELECT
t.ID as ID
, CAST(t.xmlinfo.query('
for $p in Parameters/Parameter
return
if ($p is (Parameters/Parameter[last()])[1])
then string($p/Name[1])
else concat($p/Name[1], ", ")
')
AS VARCHAR(MAX)
) as Parameter
FROM MyTable as t
Sqlfiddle Demo
The XQuery above simply loop through Parameter elements, and return Name child element if current Parameter is the last Parameter, otherwise return Name concatenated with comma.
SELECT (
SELECT ID
FROM #t
) AS ID
,X.STockData.query('Name[1]').value('.', 'Varchar(10)')
+ ', ' + X.STockData.query('Name[2]').value('.', 'Varchar(10)')
+ ', ' + X.STockData.query('Name[3]').value('.', 'Varchar(10)')
as parameter
FROM #xml.nodes('Parameters/Parameter') AS X(StockData)
Try this
I'm writing one stored procedure, which I have to create a xml column from db.
µ = CHAR(181) this is value separator,
¶ = CHAR(182) this is row separator
This is the statement I wrote. I know its not well formed.
SELECT #xmlString= CAST('<root><Section> ID =' + REPLACE(REPLACE ('20211µ1¶20212µ2', CHAR(182),
'</Section><Section> ID ='),CHAR(181), ' Slno=') + '</Section></root>' AS XML)
This is the pattern which I need to display like this.
<root>
<sections id="20211" slno="1" ></sections>
<sections id="20215" slno="2" ></sections>
</root>
declare #s varchar(50) = '20211µ1¶20212µ2'
declare #xmlString xml
;with C as
(
select T.N.value('value[1]', 'int') as id,
T.N.value('value[2]', 'int') as slno
from (select cast('<item><value>'+replace(replace(#s, 'µ','</value><value>'), '¶','</value></item><item><value>')+'</value></item>' as xml)) as X(XMLCol)
cross apply X.XMLCol.nodes('item') as T(N)
)
select #xmlString =
(
select C.id as [#id] ,
C.slno as [#slno]
from C
for xml path('sections'), root('root'), type
)
select #xmlString
Result:
<root>
<sections id="20211" slno="1" />
<sections id="20212" slno="2" />
</root>
I have a table with a XMLTYPE column named 'InvoiceXML'.
The data in this column is XML in the form:
<Invoice CustomerNum="1234" >
<CustomDeliveryDetails />
</Invoice>
When I do a
SELECT ... FOR XML PATH(''), ROOT('Invoices')
I end up with:
<Invoices>
<InvoiceXML>
<Invoice CustomerNum="1234" >
<CustomDeliveryDetails />
</Invoice>
</InvoiceXML>
</Invoices>
How do I stop the column name InvoiceXML appearing in the output?
declare #T table (invoiceXML xml)
insert into #T values (
'<Invoice CustomerNum="1234" >
<CustomDeliveryDetails />
</Invoice>
')
insert into #T values (
'<Invoice CustomerNum="4321" >
<CustomDeliveryDetails />
</Invoice>
')
select (select T.invoiceXML)
from #T as T
for xml path(''), root('Invoices')
Edit 1 The subquery (select T.invoiceXML) has no column name so it is removed.
Try:
SELECT cast(cast(InvoiceXML as nvarchar(max)) + '' as XML)
FROM whatever
FOR XML PATH(''), ROOT('Invoices')
Try this:
SELECT InvoiceXML.query('//Invoice')
FROM <YOUR_TABLE>
FOR XML PATH('')
Try specifying a xpath query to invoice in the FPR XML PATH
e.g: `FOR XML PATH('//InvoiceXML')`
I have a simple table in SQL Server 2005, I wish to convert this to XML (using the "FOR XML" clause). I'm having trouble getting my XML to look like the required output.
I've tried looking through various tutorials on the web, but I am struggling. Can someone help?
The table I have looks like this
TYPE,GROUP,VALUE
Books,Hardback,56
Books,Softcover,34
CDs,Singles,45
CDS,Multis,78
The output style I need is:
<data>
<variable name="TYPE">
<row>
<column>GROUP</column>
<column>VALUE</column>
</row>
<row>
<column>GROUP</column>
<column>VALUE</column>
</row>
</variable>
<variable name="TYPE">
<row>
<column>GROUP</column>
<column>VALUE</column>
</row>
<row>
<column>GROUP</column>
<column>VALUE</column>
</row>
</variable>
</data>
Edit:
As far as I can tell I require the multiple values. I'm generating XML for use with Xcelsius (Linking XML and Xcelsius) so have no control over in the formatting of the XML. I can generate the XML using ASP as per the linked tutorial, but I was hoping to get it straight from SQL Server.
Edit 2:
I was hoping for something elegant and tidy... but Godeke's example got the closest. Some fiddling with the SQL and I've come up with:
select
"type" as '#name',
"group" as 'row/column',
null as 'row/tmp',
"value" as 'row/column'
from tableName
for xml path('variable'), root('data')
Outputs almost in the exact way I wanted. The null/tmp line doesn't even output; it is just preventing the concatenation. Still the tag <variable name="TYPE"> repeats for each row, which I can't have.
As close as I can get is this:
select "type" as '#name', "group" as 'row/column1', "value" as 'row/column2'
from tableName
for xml path('variable'), root('data')
Naming two items the same ("column" and "column") isn't something I know how to do in one pass, but on the other hand it is an odd XML schema choice; normally elements have unique names if they contain distinct data. The obvious choice (name them both 'row/column') simply concatenates them in the output into one value.
Also note that each returned row will be a "variable" element distinct from the others. To get the nesting without redundant records will require a subquery:
select distinct "type" as '#name'
from Agent
for xml path('variable'), root('data')
was my first thought, but the distinct prevents nesting.
All this makes me think that to get the exact output you need you might have to use EXPLICIT mode. Perhaps my problem is for something like this I punt and use a DOMDocument in code :).
I prefer using for XML PATH, it provides a nicer way to control your elements etc.
