Creating Collections

Once you have declared any of these collections, you must create an instance of the collection, as in:

TYPE index_table IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
indtab index_table;

where indtab is an instance of index_table.

You can use the %TYPE attribute of a collection to link another collection’s datatype to it—for example:

TYPE varray1 IS VARRAY(20) OF NUMBER;
v1 varray1;
v2 v1%type;

If the definition of v1 changes, the definition of v2 will change along with it.
