Subject [jira] Commented: (DERBY-2604) Implement Clob support for locators
Date Thu, 03 May 2007 12:56:15 GMT

V.Narayanan commented on DERBY-2604:
------------------------------------

DERBY-2347 adds the possibility to send locators between client and server instead of LOB
values. 

DERBY-2496 adds locator support to Blobs

On the same lines we need to add locator support for Clobs also.

The changes that will be done as part of this issue will cover most of the locator work that
would need be done with respect to Clobs.

As already discussed in the JIRA issue that was raised for PreparedStatements and CallableStatements(https://issues.apache.org/jira/browse/DERBY-2529)

there are no changes needed here related to Clob also.

A similar case would exist for ResultSets also since the LOB in this case is also B-Layer
streamed and there would be no significant improvement with using locators.

Connection.createClob() will use the constructor that would be introduced in this patch which
accepts a locator as a parameter to return an empty Clob.

The locators will not be enabled with this patch.

A seperate issue will be raised to enable locators and handle test failures that might result
because of that.
