Subject [jira] Commented: (DERBY-3959) Reference Manual needs information on generated columns
Date Tue, 16 Dec 2008 18:40:44 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12657103#action_12657103

Rick Hillegas commented on DERBY-3959:

Hi Kim,

Your rewording of the ALTER TABLE material looks good to me. You could also say "The syntax
for the column-definition for a new column is a subset of the syntax for a column in a CREATE
TABLE statement..."

What I meant by value-expression is what the Reference Guide just calls an Expression. This
syntax is mentioned in the Reference Guide in the topic titled "VALUES expression". But you
are right, the Reference Guide doesn't define what an Expression is.
