see item b in my previous post.

Side note: It usually helps if the error code is included in the post, not just mentioned...

I appriciated your responce. But I never worked with the XML file Before.

I Mentioned the Mains node in the Query "FROM @xml.nodes('Mains/Parents/Parent')".

I don't know u mean to change it like that or something else.

I created my final database. And at the end i got the file with namespace.

Thanks in advance.

I deleted that </Redge> part still its not working.The last updated query which post its don't have that part still i am getting error in loading the child table.

LutzM SSC Guru Points: 107049 More actions · Answer 8

Run the code.

Read the error meassge.

Try to figure out what it means (e.g. column name not defined in the referenced table?)

Try to resolve the issue.

If you can't figure it out, post back.

Strong hint (repeated)

Thanks LutzM ,,I figured out that,,in the ParentIDreference I changed it to Parent_ID instead of Individual_ID. After running the code,,2 rows affected in parent table and 0 rows affected in the child and kid table. I tried to change the path in guery for the nodes,,but not getting any result.

I appriciate your help.

LutzM SSC Guru Points: 107049 More actions · Answer 10

You run multiple queries against the same (namespaced) xml source.

Therefore, you'd need to declare the names pace for each and every query against that xml source. Right now it's just used in the first query...

Hey LutzM,

Thanks Alot,,I got it...its working now,,,

krishusavalia SSCrazy Points: 2385 More actions · Answer 12

Hey Lutz,

Thanks for you help.

I am using the solution with cross apply for keep identity values in child nodes.

But now i am facing difficuilty because now i am getting XML file

which have more than hundred parents records and it has like more than 1000 records for child.

So runnning this code with cross apply,,,its taking more than 3 hrs to load that just one file.

Do you have any solution so I can do it without cross apply?

Thanks in advance.

Hi, I don't have your latest data/query to work with, but expanding on Lutz' excellent code, you could try this approach

DECLARE @ParentIdReference TABLE (Parent_ID INT,InternalID VARCHAR(10))

;WITH XMLNAMESPACES(

DEFAULT 'http://ALD.riban.com'

)

INSERT

INTO Parent

OUTPUT inserted.Parent_ID, inserted.InternalID

INTO @ParentIdReference

SELECT

c.value('@InternalID[1]','varchar(10)') AS InternalID,

c.value('@Action[1]','varchar(10)') AS [ACTION],

c.value('InsertUserID[1]', 'varchar(10)') AS InsertUserID,

c.value('InsertDateTime[1]', 'varchar(10)') AS InsertDateTime,

c.value('UpdateUserID[1]', 'varchar(10)') AS UpdateUserID

FROM @xml.nodes('Mains/Parents/Parent') T(c)

DECLARE @ChildIdReference TABLE (Child_ID INT,Parent_ID INT,InternalID INT)

;WITH XMLNAMESPACES(

DEFAULT 'http://ALD.riban.com'

)

INSERT

INTO Child

OUTPUT inserted.Child_ID,inserted.Parent_ID, inserted.InternalID

INTO @ChildIdReference

SELECT

p.Parent_ID,

v.value('@InternalID[1]','INT') AS InternalID,

v.value('@Action[1]','varchar(10)') AS [ACTION],

v.value('InsertUserID[1]', 'varchar(10)') AS InsertUserID,

v.value('InsertDateTime[1]', 'varchar(10)') AS InsertDateTime,

v.value('UpdateUserID[1]', 'varchar(10)') AS UpdateUserID

FROM @ParentIdReference P

OUTER APPLY @xml.nodes('Mains/Parents/Parent[ @InternalID=sql:column("P.InternalID")]/Childs/Child') U(v)

;WITH XMLNAMESPACES(

DEFAULT 'http://ALD.riban.com'

)

INSERT INTO Kid

SELECT

c.child_ID,

x.value('@InternalID[1]','INT') AS InternalID,

x.value('@Action[1]','varchar(10)') AS [ACTION],

x.value('InsertUserID[1]', 'varchar(10)') AS InsertUserID,

x.value('InsertDateTime[1]', 'varchar(10)') AS InsertDateTime,

x.value('UpdateUserID[1]', 'varchar(10)') AS UpdateUserID

FROM @ChildIdReference c

CROSS APPLY @xml.nodes('//Childs/Child[ @InternalID=sql:column("c.InternalID")]/Kids/Kid') W(x)

The key here being that this method of selecting only the relevant nodes for each parent node by use of the sql:column() function will hopefully reduce the workload...

Do you still use the XML variable?

If so, you might want o try loading the data into a table with an ID column (being the clustered index) and add an XML index.

This might help...

Question aside: how large is that file? Would you be able to provide the basic structure of the file and your current query?
