Which is best Subquery (or) joins in sql server? explain why..

Answer / rajeevrohilla

In normal situation join are best since there is no
subquery for each record for the other table. but in some
situations Subquery are best. for example- when the
subquery results one or fewer (3 or 4 records) that it will
work faster since it also saves the joining time(if there
are more than 1 joining fields then joining takes lots of
time). Subquries also perform better when tables have less
amount of data.
