----------------------------------------
Actually, I just tried the test case in Norwegian territory since I understand
it's error messages better than the Mexican error messages :) I think the
problem has nothing to do with column name containing localized characters. It
is throwing error because the column does not have not null defined on it and
hence unique/primary key can't be defined on it using ALTER TABLE. Following is
the ij session for Norwegian territory
$ java org.apache.derby.tools.ij
ij version 10.4
ij> connect
'jdbc:derby:c:/dellater/db1Norway;create=true;territory=no;collation=TERRITORY_BASED';
WARNING 01J01: Database 'c:/dellater/db1Norway' not created, connection made to
existing database instead.
ij> Create table Ciudad_de_Mexico2
( nombre varchar(24),
estado varchar(24),
Excepci≤n int );
0 rows inserted/updated/deleted
ij> ALTER TABLE Ciudad_de_Mexico2
ADD CONSTRAINT Mx_PK2 Primary Key (Excepci≤n);
ERROR 42831: 'EXCEPCI╙N' cannot be a column of a primary key or unique key
because it can contain null values.
> Alter table .. Add .. Primary Key fails with Column not found when columnName

> Project: Derby
> Issue Type: Bug
> Components: Localization
> Affects Versions: 10.3.1.1
> Reporter: Stan Bradbury
> Priority: Minor
>
> Database created with territory=es_MX and table with colunName Excepci≤n
> (taken from exception text for "ERROR XJ001: Excepci≤n de Java:...") trying
> to specify the column as the primary key using alter table fails:
> Db Creation URL: connect 'jdbc:derby:toursMx;create=true;territory=es_MX';
> -- Create table
> Create table Ciudad_de_Mexico2
> ( nombre varchar(24),
> estado varchar(24),
> Excepci≤n int );
> -- Create PK
> ALTER TABLE Ciudad_de_Mexico2
> ADD CONSTRAINT Mx_PK2 Primary Key (
> Excepci≤n);
> -- ERROR 42831: 'EXCEPCI╙N' no puede ser una columna de clave primaria o
> clave - nica porque puede contener valores nulos.
> -- WORKAROUND: create the primary key when the table is created:
> Create table Ciudad_de_Mexico
> ( nombre varchar(24),
> estado varchar(24),
> Excepci≤n int constraint mx_pk Primary Key);
