Jeremy Boynes resolved DERBY-158:
---------------------------------
Resolution: Fixed
Fix Version: 10.1.0.0
URL: http://svn.apache.org/viewcvs?view=rev&rev=156570
Log:
Fix for DERBY-158 PRIMARY KEY does not imply NOT NULL
Columns specified in a PRIMARY KEY constraint in CREATE TABLE
are implicitly set to NOT NULL per the SQL spec.
If a PRIMARY KEY constraint is added using ALTER TABLE then all
columns must also be NOT NULL. Similarly, columns
specified in a UNIQUE constraint must still be explictly NOT NULL.
