Answer Posted / pradeep
A table widout a primary key wud be difficult to use wen it
comes to calculating its data wit other tables' data.Always
better to have a primary key.Hence if ur table has all
columns w/o unique values it always better to add a column
with serial number and make it the primary key.This wud also
help u in sorting and retriving values easily.
