Inner join in SAS DI

[Ishaan]

I am joining 2 large datasets in SAS DI using SQL join transformation. I am using inner join. Out of the below options which will take less time and why?
a)
Proc sql;
Create table abc as select a., b.city  from emp as a, emp_details as b
Where a.empid=b.empid;
Quit;
b)
Proc sql;
Create table abc as select a., b.city  from emp inner join emp_details as b
On a.empid=b.empid;
Quit;

Well, if you have the data, try and compare.
I would suspect that the performance is the same.

They both are the same code. I could expect the same performance either .
