table tbl_event_log
columnName DataType
id Int
event XML
userinfo XML
and data should be in event is
<Event><Player readName="9.Make You Talk!" demoName="Video Game" **portal="FB"** totalDuration="0:07/0:07(100%)" /></Event>
and i want to write query to get data from portal="FB"
Use nodes() method to split your rows and then get values:
Check this solution and hope it helps you:
Declare #mytable table (id int,event xml,userinfo varchar(200))
Insert into #mytable
select 1, '<Event><Player readName="9.Make You Talk!" demoName="Video Game" portal="FB" totalDuration="0:07/0:07(100%)" /></Event>','Test'
Union
select 2, '<Event><Player readName="9.Make You Talk!" demoName="Video Game" portal="TW" totalDuration="0:07/0:07(100%)" /></Event>','Test'
select
s.id,
e.p.value('#portal', 'varchar(max)') as portal
from #mytable as s
outer apply s.event.nodes('Event/Player') as e(p)
select * from (
select
s.id,
e.p.value('#portal', 'varchar(max)') as portal
from #mytable as s
outer apply s.event.nodes('Event/Player') as e(p)
) Test
where Test.portal = 'FB'
Attn: Replace #mytable with your table name.
Note: Event column in your table must be XML datatype.
To get the data into specific fields you could extract them directly from the xml.
For example:
select id, userinfo,
event.value('/Event[1]/Player[#portal="FB"][1]/#readName','varchar(max)') as readNameFB,
event.value('/Event[1]/Player[#portal="FB"][1]/#demoName','varchar(max)') as demoNameFB,
event.value('/Event[1]/Player[#portal="FB"][1]/#totalDuration','varchar(30)') as totalDurationFB
from tbl_event_log;
[#portal="FB"] : only get the Player tags where the portal="FB"
[1] : use the first one

I have a table column consist with the XML files. I want to read XML data and display it.
I come up with the following code. But it read only one row in the column
want to display other XML data also
declare #xml xml
select #xml = event_data_XML from #temp
SELECT * FROM (
SELECT
CAST(f.x.query('data(#name)') as varchar(150)) as data_name,
CAST(f.x.query('data(value)') as varchar(150)) as data_value
FROM #xml.nodes('/event') as t(n)
CROSS APPLY t.n.nodes('data') as f(x)) X
PIVOT (MAX(data_value) FOR data_name IN (NTDomainName, DatabaseName, ServerName)) as pvt
Output should be like this(NTDomainName, DatabaseName, ServerName are xml data)
There are a bunch of ways you could do this. I'll show you a way I think you'd find easiest.
To start, here's a table with a little test data:
CREATE TABLE dbo.stuff (
id int identity (1,1) primary key
, event_data_xml xml
, create_date datetime default(getdate())
, is_active bit default(1)
);
INSERT INTO dbo.stuff (event_data_xml)
VALUES ('<event name="thing" package="as">something</event>')
INSERT INTO dbo.stuff (event_data_xml)
VALUES ('<event name="otherthing" package="as">something else</event>')
---All records
SELECT * FROM dbo.[stuff];
Make sense so far? Here's the query I'd use if I wanted to mix XML data and column data:
---Parsed up
SELECT event_data_xml.value('/event[1]', 'nvarchar(max)') AS [parsed element #text]
, event_data_xml.value('/event[1]/#name', 'nvarchar(max)') AS [parsed attribute value]
, create_date --column from table
FROM dbo.stuff
WHERE is_active = 1;
Using the value() function on the XML column passing in an xpath to what I want to display and SQL Server data type for how I want it returned.
Just make sure you're selecting a single value with your xpath expression.
Hi all I have a table that holds my business Id's and it is varchar(255) data type
I also have a separate table that stores an XML structured document in a text data type column when the business gets approved by a lender (it stores the companys information etc).
I am trying to return all business ID's that are NOT approved by a lender, the only way i can know this is if the business ID does not exist in the XML.
I cannot join on any tables as i do not have any relational data, but i am trying to subquery it.
Any ideas? here is what i have
Select bus_id
From dbo.tbl_business
Where bus_id Not In (
Select Cast(company_xml_info As Varchar(Max))
From tbl_company_reports
Where Cast(company_xml_info As Varchar(Max)) Is Not Null
And company_xml_info Like '%Business id="' + bus_id + '"%'
And company_xml_info Is Not Null
And company_xml_current_status = 'Approved'
)
Here is an example mark of something similar you can do. This should run fine in SQL Management Studio 2008 and up:
DECLARE #Data TABLE (BusinessId VARCHAR(8))
INSERT INTO #Data (BusinessId) VALUES ('A68'),('A69'),('A70');
DECLARE #CompanyXml TABLE (company_xml_info VARCHAR(MAX));
INSERT INTO #CompanyXml (company_xml_info ) VALUES ('<CompanyInfo>
<Businesses>
<Business id="A68">
<Businessceo>Test</Businessceo>
</Business>
</Businesses>
</CompanyInfo>')
,('<CompanyInfo>
<Businesses>
<Business id="A70">
<Businessceo>Test2</Businessceo>
</Business>
</Businesses>
</CompanyInfo>')
--Data as is
Select *
From #Data
--example of your code as is
SELECT *
From #CompanyXml
--exclusionary listing
SELECT *
From #Data
EXCEPT
--the secret of this is part 1 casting it to xml. Then you extend that with '.value'. That wants a structure to get to the Id.
--I wrap that in ()'s then say the first instance of that [1] as in theory you could have more instances and do very complex parsing.
--Then it needs a type of sql to transform this value into
SELECT CAST(company_xml_info AS XML).value('(CompanyInfo/Businesses/Business/#id)[1]', 'varchar(8)')
From #CompanyXml

If you have something that has repeat elements in a tree structure of your XML, I prefer the 'nodes' method of repeating them and then you do not have to worry about using a first. You merely need to iterate through what you have from the use of the 'nodes' syntax and get a value like so
DECLARE #X XML = '<CompanyInfo><Businesses><Business id="C1405"/><Business id="C1408"/><Business id="C1408"/></Businesses> </CompanyInfo>'
SELECT
x.query('.')
, x.value('#id', 'varchar(8)')
FROM #X.nodes('/CompanyInfo/Businesses/Business') AS y(x)
I have a list of values such as
1,2,3,4...
that will be passed into my SQL query.
I need to have these values stored in a table variable. So essentially I need something like this:
declare #t (num int)
insert into #t values (1),(2),(3),(4)...
Is it possible to do that formatting in SQL Server? (turning 1,2,3,4... into (1),(2),(3),(4)...
Note: I can not change what those values look like before they get to my SQL script; I'm stuck with that list. also it may not always be 4 values; it could 1 or more.
Edit to show what values look like: under normal circumstances, this is how it would work:
select t.pk
from a_table t
where t.pk in (#place_holder#)
#placeholder# is just a literal place holder. when some one would run the report, #placeholder# is replaced with the literal values from the filter of that report:
select t.pk
from a_table t
where t.pk in (1,2,3,4) -- or whatever the user selects
t.pk is an int
note: doing
declare #t as table (
num int
)
insert into #t values (#Placeholder#)
does not work.
Your description is a bit ridicuolus, but you might give this a try:
Whatever you mean with this
I see what your trying to say; but if I type out '#placeholder#' in the script, I'll end up with '1','2','3','4' and not '1,2,3,4'
I assume this is a string with numbers, each number between single qoutes, separated with a comma:
DECLARE #passedIn VARCHAR(100)='''1'',''2'',''3'',''4'',''5'',''6'',''7''';
SELECT #passedIn; -->: '1','2','3','4','5','6','7'
Now the variable #passedIn holds exactly what you are talking about
I'll use a dynamic SQL-Statement to insert this in a temp-table (declared table variable would not work here...)
CREATE TABLE #tmpTable(ID INT);
DECLARE #cmd VARCHAR(MAX)=
'INSERT INTO #tmpTable(ID) VALUES (' + REPLACE(SUBSTRING(#passedIn,2,LEN(#passedIn)-2),''',''','),(') + ');';
EXEC (#cmd);
SELECT * FROM #tmpTable;
GO
DROP TABLE #tmpTable;
UPDATE 1: no dynamic SQL necessary, all ad-hoc...
You can get the list of numbers as derived table in a CTE easily.
This can be used in a following statement like WHERE SomeID IN(SELECT ID FROM MyIDs) (similar to this: dynamic IN section )
WITH MyIDs(ID) AS
(
SELECT A.B.value('.','int') AS ID
FROM
(
SELECT CAST('<x>' + REPLACE(SUBSTRING(#passedIn,2,LEN(#passedIn)-2),''',''','</x><x>') + '</x>' AS XML) AS AsXml
) as tbl
CROSS APPLY tbl.AsXml.nodes('/x') AS A(B)
)
SELECT * FROM MyIDs
UPDATE 2:
And to answer your question exactly:
With this following the CTE
insert into #t(num)
SELECT ID FROM MyIDs
... you would actually get your declared table variable filled - if you need it later...
I have a table where a column contains XML data. Now i want to retrieve those xml data with restriction of nodes. Kindly see the following example for more explanation on my scenario,
declare #table table (id int, xmlfield xml) insert into #table select 1,'<Root xmlns="">
<Sample>
<Issue>
<Level>one</Level>
<Descp>First Example</Descp>
</Issue>
<Issue>
<Level>two</Level>
<Descp>Second Example</Descp>
</Issue>
</Sample> </Root>'
select * from #table
Now i need the following result set
Id XMLfield
1 first example
ie, for the selected level,i need the decription for it. More clearly, the node should be restricted for <level>one</level>
(need: What is the description for level one ?)
thanks in advance
Have a look at the xml Data Type Methods
select id,
xmlfield.value('(//Issue[Level = "one"]/Descp/text())[1]', 'varchar(100)') as XMLField
from #table
The XQuery you're looking for is
//Issue[Level = "one"]/Descp/data()
I want to get one xml node value from NTEXT column which contains xml based on where clause quering on another xml node value.
RDBMS Type: Microsoft SQL Server T-SQL
Here: I want to get Code node value based on StoreId where clause value. How do I get it?
Input: 100
Output:ABCDE
For example:
<root>
<StoreProfile>
<General>
<StoreId>100</StoreId>
<Code>ABCDE</Code>
</General>
</StoreProfile>
</root>
If you are using SQL Server 2005 or 2008 you can use XQuery like so:
For more on XQuery see XQuery Language Reference
DECLARE #storeId INT
SET #storeId = 100
CREATE TABLE #TestTable
(
xmlColumn NTEXT
)
INSERT INTO #TestTable (xmlColumn) Values('<root><StoreProfile><General><StoreId>100</StoreId><Code>ABCDE</Code></General></StoreProfile></root>')
INSERT INTO #TestTable (xmlColumn) Values('<root><StoreProfile><General><StoreId>200</StoreId><Code>FGHIJ</Code></General></StoreProfile></root>')
SELECT
StoreProfile.value('Code[1]', 'nvarchar(10)') as Code
FROM #TestTable
CROSS APPLY (SELECT CAST(xmlColumn AS XML)) AS A(B)
CROSS APPLY A.B.nodes('//root/StoreProfile/General[StoreId = sql:variable("#storeId")]') AS StoreProfiles(StoreProfile)
DROP TABLE #TestTable
