Thanks for the reply. I can't copy my data here.if you think based on data it is possible to get this type of output,please  provide sample data to suit this output. Don't mind.

 

data set A=284 records

data set B=284 records

A Except B=281

B Except A=281

A intersect/intersect all B=0

datalines;
a 1
a 1
b 2
c 3
;

data second;
input a $ b;
datalines;
d 4

Your first and second should contain duplicated obs .
using ALL to retain all the obs .

SELECT * FROM first
intersect all
SELECT * FROM second;
