# G-2340: Always define your VARCHAR2 variables using CHAR SEMANTIC (if not defined anchored).

Minor

Reliability

## Reason

Changes to the nls_length_semantic will only be picked up by your code after a recompilation.

In a multibyte environment a varchar2(10) definition may not necessarily hold 10 characters when multibyte characters are part of the value that should be stored, unless the definition was done using the char semantic.

 1 2 3 4 create or replace package types_up is subtype description_type is varchar2(200); end types_up; /
