what are pl/sql collections?
Answer Posted / 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.
