Package procedure arguments error using table of

Question

Hi ,
I have the following definition for my package
CREATE OR REPLACE package a_test_pkg as
type a_type is table of varchar2(10) index by binary_integer;
procedure a_proc (name in a_type);
end;
CREATE OR REPLACE package body a_test_pkg as
procedure a_proc (name in a_type)
as
begin
dbms_output.put_line('Hello');
end;
end;
when i am trying to execute it using
begin
a_test_pkg.a_proc(name=>'hello');
end;
why am I getting errors?

Answer 1

You are getting errors because 'Hello' is not a a_test_pkg.a_type type variable, it is a VARCHAR2.
You need to call the procedure more like:
SQL> DECLARE
  2     l_t a_test_pkg.a_type;
  3  BEGIN
  4     l_t(1) := 'Hello';
  5     a_test_pkg.a_proc(l_t);
  6  END;
  7  /
Hello
PL/SQL procedure successfully completed.You can only call a PL/SQL type (the INDEX BY makes it a PL/SQL type) from within PL/SQL.
