newbie question about join

I'm a little bit confused, are these two select statements synonymous? The second one has a 'join...on', while the first one does not.

select t.* from user_tab_cols t, user_all_tables a

    where t.table_name = a.table_name;

select t.* from user_tab_cols t join user_all_tables a

    on (t.table_Name = a.table_name); Received on Fri Feb 23 2007 - 17:10:45 CST
