Subject [jira] Commented: (DERBY-3853) Behaviour of setTypeMap() differs between embedded and client
Date Sat, 11 Apr 2009 06:40:14 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3853?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12698056#action_12698056

Yun Lee commented on DERBY-3853:
--------------------------------

Knut, I'm happy to hear it will be commited soon! Thanks!

By what you explained so clearly, I've got why it's better to make changes on client side
now.

I have browsed the coding convention doc, and will follow it in my work on Derby.

> On the embedded driver, Connection.setTypeMap() behaves like this (when the connection
is not closed):
>   - if the map argument is null, throw an SQLException with SQLState XJ081
>   - if the map is not null and not empty, throw an SQLException with SQLState 0A000
>   - if the map is not null and empty, do nothing
> The behaviour on the client driver is this:
>   - always throw an SQLException with SQLState 0A000
> We should try to make the two drivers behave the same way when setTypeMap() is called.
(This would also allow us to simplify some of the tests in J2EEDataSourceTest).
