updating cursor with multiple tables-84

A nested table type or varray type that is created at schema level (with the CREATE TYPE Statement) is stored in the database, and you can manipulate it with SQL statements.

A collection has only one dimension, but you can model a multidimensional collection by creating a collection whose elements are also collections.

And I implemented the same idea in designing Invoice template.

However, it had single column data list and today we will be updating the same template with multi-column data validation list.

DECLARE 2 -- Associative array indexed by string: 3 4 TYPE population IS TABLE OF NUMBER -- Associative array type 5 INDEX BY VARCHAR2(64); 6 7 city_population population; -- Associative array variable 8 i VARCHAR2(64); 9 10 BEGIN 11 -- Add new elements to associative array: 12 13 city_population('Smallville') := 2000; 14 city_population('Midland') := 750000; 15 city_population('Megalopolis') := 1000000; 16 17 -- Change value associated with key 'Smallville': 18 19 city_population('Smallville') := 2001; 20 21 -- Print associative array: 22 23 i := city_population.
