what are pl/sql collections?..

Answer / pradeep

A collection is an ordered group of elements, all of the
same type. It is a general concept that encompasses lists,
arrays, and other familiar datatypes. Each element has a
unique subscript that determines its position in the collection.

PL/SQL offers these collection types:

* Index-by tables,
* Nested tables
* Varrays

Answer / debanjan rudra

pl/sql collections are temporary table types which helps
the programmer to "temporary" manipulate data comprising
more than 1 row (i.e. not scalar).

Eg. CREATE OR REPLACE TAB AS TABLE OF VARCHAR2(100) INDEX
BY PLS_INTEGER;

In the above example "TAB" is a collection which shall be
used to temporarily store more than 1 varchar2 records.
