Inner join vs Where

Question

Is there a difference in performance (in oracle) between

Select * from Table1 T1 
Inner Join Table2 T2 On T1.ID = T2.ID

And

Answer 1

Don’t forget that in Oracle, provided the join key attributes are named the same in both tables, you can also write this as:

select *
from Table1 inner join Table2 using (ID);

This also has the same query plan, of course.
