Subject [jira] Commented: (DERBY-3920) Allow altering size limits for blob and clob columns
Date Mon, 01 Jun 2009 20:41:07 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3920?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12715245#action_12715245
] 

Evan Leonard commented on DERBY-3920:
-------------------------------------

I have databases in production that were created with the default blob limit of 1mb by accident.
I now need to change the dbs to allow much larger blobs. Without this feature is there any
work around?

> I would like to increase the size limit of some CLOB columns (actually, I'd like to remove
the limit.)
> So I tried this:
>   ALTER TABLE t ALTER c SET DATA TYPE CLOB
> But of course it's not supported.
> I figure this can't be any harder than it was to do the same thing for VARCHAR, although
I don't actually know.
