Hi Gary,
This will execute a joined query similar to:
SELECT A0.*
FROM Person A0 INNER JOIN Email A1
ON A0.EmailID = A1.EmailID
WHERE A0.name = X
AND A1.address = Y
So, yes, it will check all "addresses inside emails". And if emails is
null, it will return an empty collection.
Hope this helps,
Wally

Thanks.
Will this check all the "address"es inside "emails?"
Or just the first? Or...
And what if emails is null?
Thanks again, Gary
