Yes, you can. The following (absolutely useless in terms of the result) query shows it:


select c.name
from sys.objects as o
join sys.columns as c on o.object_id = c.object_id
OR ( (o.object_id = c.object_id
AND o.object_id = 4) )



Regards,
Andras

You can put anything you'd put in a Where clause, into a join clause. Some things might be a bad idea, but you can technically do it.

but if we analyze its impact on performance then it may not be bad idea at all?
