Problems passing a nested table or Varray as a parameter

Question

Hi,
could some one please show me the code for passing a varray or a table as a parameter in a PL/SQL function or procedure.
I have tried a number of ways but am not getting anywhere fast. A small bit of sample code that shows a function that takes a table/varray as a parameter and uses it to do something, and code also for the method that calls this function which demonstrates how the table/varray is created and passed.
I have a good idea how I think this should be done but cant get it to work in practice.
Thanks and happy new year!

Answer 1

sql >> CREATE OR REPLACE TYPE t_listachar
2 AS TABLE OF VARCHAR2(100)
3 /
Type created.
sql >> CREATE OR REPLACE PROCEDURE prcl_nested
2 (
3 p_Array IN t_ListaChar
4 )
5 IS
6 BEGIN
7 --
8 FOR i IN p_Array.FIRST .. p_Array.LAST LOOP
9 --
10 dbms_output.put_line('p_Array('||i||'): '||p_Array(i)) ;
11 --
12 END LOOP ;
13 --
14 END ;
15 /
Procedure created.
sql >> DECLARE
2 --
3 t_Array t_ListaChar := t_ListaChar('1','2','3','4','5') ;
4 --
5 BEGIN
6 --
7 prcl_nested(t_Array) ;
8 --
9 END ;
10 /
p_Array(1): 1
p_Array(2): 2
p_Array(3): 3
p_Array(4): 4
p_Array(5): 5
