Re: Is there any performance loss if i have all my columns preceeded with dbo.Tablename?

Hi

There should be no noticable loss if any, although in your example as you
are only selecting from the one table it is not necessary for any reference.
You may want to look at using a table alias which will save typing and also
(probably) make the statement clearer.
