Subject [jira] Commented: (DERBY-1706) NullPointerException occurs when trying to create a table in schema SESSION
Date Fri, 15 Sep 2006 18:26:24 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1706?page=comments#action_12435075 ] 
            
Suresh Thalamati commented on DERBY-1706:
-----------------------------------------

Hi Mamta, 

just a general question:

Why is it necessary to allow users to create a non-temporary tables in the "session" schema
, when the schema is not created explicitly ?


Thanks
-suresh
