I am wondering if there's any difference between inner join and left join if I am self merging. 

 

Say I use the DOSING data set in the following document

http://www2.sas.com/proceedings/sugi25/25/cc/25p109.pdf

 

And I condition it on patient ID = patient ID, Then using inner join and left join would create the same result right?

There are plenty of resources that graphically show what joins do.
