Answer Posted / mehul.v.thakkar@gmail.com
There are basically three types of joins in SAS,
1. Inner Join
2. Left Join
3. Right Join
Inner Join gives the records which are present in both the
datasets.
Left join gives all the records that are present in left
dataset irrespective of whether they have a matching record
in the right dataset.
Right join gives all the records in the right dataset
irrespective of whether they have a matching record in the
left dataset.
