Good Sample. In the select statement,
SELECT @xml.exist(‘/ninjaElement[@id=sql:variable("@id")]‘)

can I give the condition itself in a variable? Have you tried out?

Oh, whoa, this saved me from a few gray hairs. I was trying to get the value of an XML element that existed in some columns, but not all, and adding it with similar elements in the same column (quantity1, quantity2, etc). In some instances, quantity1 didn’t exist, yet quantity2 or quantity3 would, but the whole addition statement would be null. Now I check if the element exists; if it doesn’t, the case statement returns 0; otherwise, it returns the value of the element.

Thank you!

Found a small problem … you declare:

DECLARE @xmlSnippet XML

And then assign:

SET @xmlSnippet =

But in the queries you refer to @xml, which doesn’t exist:

SELECT @xml.exist('//ninjaElement')

Hi, how can use xml in join clause? e.g. I have a xml variable and want to make something like this

table t1
join @XML.nodes(‘/root/id’) as ParamValues(ID)
on t1.id=ParamValues.ID.value(‘.’,'int’)
