Subject [jira] Commented: (DERBY-142) ResultSetMetaData.isReadOnly() also returns wrong results
Date Wed, 12 Oct 2005 04:12:10 GMT
    [ http://issues.apache.org/jira/browse/DERBY-142?page=comments#action_12331862 ] 

Mamta A. Satoor commented on DERBY-142:
---------------------------------------

Looks like the Derby requirement of "FOR UPDATE" on updatable resultsets is causing quite
a bit of headache. There is improvement "Derby-231 "FOR UPDATE" required for updatable result
set to work" filed for the very same issue and it might be worth the efforts for someone to
look into possibly not requiring it.

> ResultSetMetaData.isReadOnly() always returns true, even when writing to the table is
possible.  
> The JDBC 2.0 spec says: "ResultSetMetaData.isReadOnly() : Indicates whether the designated
column is definitely not writable.", so the method should return false for a table.
> I will attach a testcase for this behaviour.
