Subject [jira] Commented: (DERBY-2257) Implementing the stored procedures called by the LOB related JDBC methods
Date Thu, 22 Feb 2007 10:41:05 GMT

V.Narayanan commented on DERBY-2257:

Thank you for the comments again,

The situation you have pointed out is when the database is read-only. This would mean that
the create procedure calls would fail. The server should be able to detect this and will not
send locators. It will send the LOB instead and the client should be intelligent enough to
handle this. The comments on Derby-2347 also point towards the same. 

I have copied the following from comments on - Derby -2347 today morning
"Anyhow, the client will be made so that it also handles receiving LOBs when it had requested
locators.  "

If the procedures are created the client will receive locators. Otherwise it will receive
LOB's and will handle that. 

Even if we decide not to do it the soft upgrade by creating all the procedures we would need
a mechanism that would provide the functionality without locators. We can use that same when
the procedures are not there and resort to the locator implementation if we were able to create
the procedures.

Note that this is still the way I think can be done. I do not have code to support what I
propose at this juncture but will come up with it in the upgrade JIRA issue.
