I have a table with a xml column.
Xml is similar to
<Root>
<Row>
<user>abc</user>
<Rowid>1</Rowid>
</Row>
<Row>
<user>vf</user>
<Rowid>2</Rowid>
</Row>
<Row>
<user>ert</user>
<Rowid>3</Rowid>
</Row>
<Maxrowid>3</Maxrowid>
</Root>
Now below query return sl_no column and myxmlcolumn of rows containing xml column having values 'abc' or 'xyz' in node 'user'(<user>).Below query i am using similar to IN option of sql.
SELECT [mytable].[Sl_no],[mytable].[myxmlcolumn] FROM [mydb].dbo.[mytable] WHERE ( [myxmlcolumn].exist('for $x in /Root/Row where ( ($x/user[fn:upper-case(.)=(''ABC'',''XYZ'')]) ) return $x')>0 )
I want similar kind of query which does same work as sql 'NOT IN' does. That is in my case i want rows not having values 'abc' or 'xyz' in node 'user'(<user>) in xml column.
So please help me on this.

Maybe I misunderstand what you are looking for, but is it as simple as changing "> 0" to "= 0"?

I agree with Erland, just change the test to equality with zero, unless you actually want to extract the non-matching nodes from the xml?

I would add that this may be a quicker way to test than using that flwor loop...

where myxmlcolumn.exist('Root/Row/user[fn:upper-case(.)=("ABC","XYZ")]')=0
