Subject [jira] Commented: (DERBY-3959) Reference Manual needs information on generated columns
Date Tue, 16 Dec 2008 14:02:44 GMT

Rick Hillegas commented on DERBY-3959:
--------------------------------------

Hi Kim,

Thanks for looking at this issue.

1) You are right that you have fewer options with ALTER TABLE. The ALTER TABLE syntax should
be changed as follows:

Simple-column-Name [ DataType ]
[ Column-level-constraint ]*
[ [ WITH ] DEFAULT DefaultConstantExpression
   | generation-clause
]

2) I agree that DERBY-1909 removes the restriction you found.

Thanks!
