create table #T (

ID int identity primary key,

XMLCol XML);

insert into #T (XMLCol)

select ' ';

insert into #T (XMLCol)

select '';

insert into #T

default values;

select *

from #T

where XMLCol is not null and cast(XMLCol as varchar(max)) != '';

That seems to work. Try it on yours.

Of course, using a cast function like that in the Where clause will slow the query down, but at least it will get the job done.

I think you may have posted in the wrong forum as this is a 2000 forum, but you should try this:

DECLARE @var XML

SET @var = '' -- '<test>test</test>'

SELECT @var.exist('/test')

IF @var IS NOT NULL AND @var.exist('/test') = 1

BEGIN

SELECT 'not null'

END

ELSE

BEGIN

SELECT 'null'

END
