Read xml file and put values into sql table by MERGE - mysql

Question

I got an XML file looking like this:
<ns0:Currency xmlns:ns0="http://bla.bla.Currency">
<Currency>
<IntComp>08</IntComp>
<Active>1</Active>
<Currency>USD</Currency>
<Text>US Dollar</Text>
</Currency>
</ns0:Currency>
Edit: I need to take all these fields inside Currency and fit them into table, this should work for all files looking like this. Not only these values.
I want to put these values into my sql table which have the same columns, i would like to Merge these values into the table so it will Update if the IntComp value && Currency match match with another file. And it will Insert if the file doesnt match.
I havent figured out how to write this sql query.
EDIT:
The tables look like this.
dbo.Integration
ID | XMLData | Entity | EntityId | Action | ....
XMLData is the string with XMLData that i want to send to another table and pick out those node from that field.
The other table:
dbo.Currency
ID | IntComp | Active | Currency | Text
This is what ive been trying so far:
SELECT XMLData.value('(/ns0:Currency xmlns:ns0="http://bla.bla.Currency/Currency/IntComp/node())[1]', 'int') as intComp,
XMLData.value('(/ns0:Currency xmlns:ns0="http://bla.bla.Currency/Currency/Active/node())[1]', 'int') as Active,
XMLData.value('(/ns0:Currency xmlns:ns0="http://bla.bla.Currency"/Currency/Currency/node())[1]', 'varchar(10)') as Currency,
XMLData.value('(/ns0:Currency xmlns:ns0="http://bla.bla.Currency"/Currency/text/node())[1]', 'varchar(MAX)') as Active
FROM dbo.Integration

May be you can try something like this..
DECLARE #DocHandle AS INT;
DECLARE #XmlDocument AS NVARCHAR(1000);
SET #XmlDocument = '<ns0:Currency xmlns:ns0="http://bla.bla.Currency"><Currency><IntComp>08</IntComp><Active>1</Active><Currency>USD</Currency><Text>US Dollar</Text></Currency></ns0:Currency>';
EXEC sys.sp_xml_preparedocument #DocHandle OUTPUT, #XmlDocument,'<ns0:Currency xmlns:ns0="http://bla.bla.Currency"/>';
MERGE INTO tmp1 AS TGT
USING (SELECT IntComp,Active,Currency,Text FROM OPENXML (#DocHandle, '/ns0:Currency/Currency',11) WITH (IntComp INT,Active INT,Currency varchar(10),Text nvarchar(100)))
AS SRC ON SRC.IntComp = TGT.IntComp and SRC.Currency = TGT.Currency
WHEN MATCHED THEN UPDATE
SET TGT.IntComp = SRC.IntComp , TGT.Currency = SRC.Currency
WHEN NOT MATCHED THEN INSERT
VALUES(SRC.IntComp,SRC.Active, SRC.Currency, SRC.Text);
select * from tmp1
