PL/SQL numeric error:character buffer string too small

Question

I am always getting this error message when I first try to run my package.
But this always happen on the first time. When I then try to run it for second time, no problem.
So it can't be due to syntax or logic.
Could it be due to package state?

Answer 1

How are they being initialised? Is it just a straight assignment?
Can you copy + paste the exact error you are getting...
SQL> CREATE OR REPLACE PACKAGE pkg_Test
  2  IS
3 pc_TooBig CONSTANT VARCHAR2(1) := 'AB';
  4
  5     PROCEDURE p_test;
  6  END;
  7  /
Package created.
SQL> CREATE OR REPLACE PACKAGE BODY pkg_Test
  2  IS
  3
  4     PROCEDURE p_test
  5     IS
  6
  7     BEGIN
  8
  9             dbms_output.put_line('Test');
10
11     END;
12  END;
13  /
Package body created.
SQL> exec pkg_test.p_test;
BEGIN pkg_test.p_test; END;
