No, but Query one is better, it will allow you to adapt to changes. If
someone adds a column to your table and you select *, all of a sudden all
your applications break as there are more columns than originally
inticipated. You can program to prevent this, but naming all the columns is
#1 self documenting, 2# safer.

Gurus,
Will there be any performance gain by going for query1 instead of query2.
Query1:
select col1,col2, col3,..col2n from tab;
Query2:
select * from tab;
Thanks,
SIva
