Cross Apply And Newid

Hi,

Why am I getting a different numbers of distinct ids in those queries?


USE AdventureWorks
go
Declare @myXml as xml
set @myXml = '
<lol>omg</lol>
<lol>rofl</lol>
';

select locations.*, T.c.value('.','nvarchar(max)') from
(
select newid() as Id
from Production.ProductModel
where ProductModelID in (7, 8)
) as locations cross apply @myXml.nodes('(/lol)') T(c);

select mytable.* , T.c.value('.','nvarchar(max)') from
(
select newid() as Id
union
select newid()
) as mytable cross apply @myXml.nodes('(/lol)') T(c);


Thanks,

Victor
