PRIMARY KEY does not imply NOT NULL
-----------------------------------
Key: DERBY-158
URL: http://issues.apache.org/jira/browse/DERBY-158
Project: Derby
Type: Bug
Components: SQL
Reporter: Bernt M. Johnsen
Priority: Minor
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).
