Subject [jira] Commented: (DERBY-495) COALESCE
Date Tue, 15 Aug 2006 20:11:14 GMT
    [ http://issues.apache.org/jira/browse/DERBY-495?page=comments#action_12428210 ] 
            
Matt Frantz commented on DERBY-495:
-----------------------------------

The proposed documentation does not allow for the possibility of invoking COALESCE with a
single argument.  Should it read as follows?

COALESCE (expression[,expression]...)

If the single-argument case is not supported, then maybe it should be.  (This case is nice
for SQL-generator applications.)
