I have Two files, loaded as Two relations A and B as fallows
File1.txt
--------------
ramana
krishna
siva
venkat
File2.txt

basha
these two files are loaded into two relations A and B
and then
the output should be like the difference of the two i.e B - A
that means the extra added added users in B without A
output
