Use proc sql for joins,
There are 5 types of joins in sas
1) Inner Join :- Output would be only matched cases.
2) left outer Join :- Output would be all the rows from
left table with corresponding matched value from right
table.
3) right Join :- vice versa of left Join.
4) Full outer join :- will take all matched & unmatched
rows of both the tables.
5) Product Join :- this will join the 2 tables without any
common variable.
