>          Key: DERBY-158
>          URL: http://issues.apache.org/jira/browse/DERBY-158
>      Project: Derby
>         Type: Bug
>   Components: SQL

> PRIMARY KEY does not imply NOT NULL. Derby issues error message:
> ij> create table tab (i integer primary key);
> ERROR 42831: 'I' cannot be a column of a primary key or unique key because it can contain null values.
> This is neither compliant with SQL-92 nor with SQL-99 (Feature E141-08, I think).
