Question

A candidate key must uniquely identify each row.
A.TRUE
B.FALSE

Answer 1

No it is not necessary to identify .False

Answer 2

It is FALSE..

because.. A candidate key is a column, or set of columns, in a table that can uniquelyidentify any database record without referring to any other data. Each table may have one or more candidate keys, but one candidate key is unique, and it is called the primary key.

and A primary key is a unique representative attribute for a particular row of data.

hope this will help u... :-)
