Answer / rohit

If you cannot use the primary index to determine the result
set because, for example, none of the fields primary index
occur in the WHERE or HAVING clause, the system searches
through the entire table (full table scan). For this case,
you can create secondary indexes, which can restrict the
number of table entries searched to form the result set.

You should only create secondary indexes, for database
tables from which you mainly read, since indexes have to be
updated each time the database table is changed. secondary
indexes should contain columns that you use frequently in a
selection, and that are as highly selective as possible to
improve performance..
