Subject [jira] Commented: (DERBY-208) Add support to retrieve lobs for Network Server by locator rather than matierializing the LOB
Date Wed, 20 Dec 2006 18:56:22 GMT
    [ http://issues.apache.org/jira/browse/DERBY-208?page=comments#action_12460017 ] 
            
Øystein Grøvlen commented on DERBY-208:
---------------------------------------

Great work with the thorough use-cases, Fernanda.  

I suggest to go for an implementations where locators work on copies and not directly on the
LOBs.  Working directly on a LOB can change the behavior of current applications since updates
may occur without a call to updateRow().  Hence, applications which sets parameters and then
for some reason skips updateRow(), will experience a changed behavior.  Also, it seems like
the infrastructure for working on a copy will be needed anyway in order to temporarily store
LOBs that have not yet been assigned to a row.

> Currently Network Server materializes all LOB objects.  LOB locator support is part of
the DRDA spec so could be added to network server.  See

> It is not clear if SQL Support for LOB locators would also be required.
