Subject [jira] Commented: (DERBY-522) ERROR X0Y79 raised when adding comments using "--" before sql queries with Network Client
Date Fri, 14 Oct 2005 17:57:45 GMT
    [ http://issues.apache.org/jira/browse/DERBY-522?page=comments#action_12332094 ] 

Kathey Marsden commented on DERBY-522:
--------------------------------------

I reviewed this patch and my only comment is that I think that the ij change should strip
comments for JCC or for     Derby client drivers  whose version is less than 10.2.  That way
the behaviour is dependent upon which client the ij tool is working with and a 10.2 ij will
continue to work with 10.1 client.
