Today, I have one requirement to check dynamically if a node exists in my xml or NOT. I have a stored procedure that receives XML and I need to check if the message information xml contains one Node or NOT. If that node exists then I need to execute that Stored Procedure by different logic and if not it should run with different logic.
I figure it out by using EXISTS.
This is my XML, that I got as parameter.
DECLARE @ExportData XML
SELECT @ExportData =
<EachData Parts="Test1" /> <EachData Parts="Test2" /> <EachData Parts="Test3" /> </BulkData>
Now I need to check if "BulkData" node exists in XML, then I need to write different logic to get the result.
So, I used this
This will return "1" if node is exists else return "0".
That's it. I can write based on the return result by this statement.
Let me know if it helps you.
