Re: [Dspace-tech] replace a bitstream

Re: [Dspace-tech] replace a bitstream
But if I do change thee sequence_id it wont affect anything, right? I think that's what you're saying also. but want to confirm. Thank you!

Don't worry about what the sequence_id is as long as they're in the order you want.

Re: [Dspace-tech] replace a bitstream
sequence_id doesn't affect anything but ordering of bitstreams in the UIs. Bitstreams are uniquely identifiable without sequence_id.

[Dspace-tech] replace a bitstream
One of our users has loaded an item with one bitstream. He would like to replace the bitstream to be able to use the same url as the existing bitstream. I see that if I delete the bitstream and add a new one, the sequence_id number is increased and the url changes, so I would like to issue a sql command to change the sequence_id in bitstream table to the old sequence_id so the url stays the same. I have tried this in my development environment, and it worked fine. From looking at the code I don't think this will screw up discovery or lucene indexing ( I don't see sequence_id being used there), so I think it is safe to do this. I just want to make sure before I do this in production. We don't expect this to happen again, and want to accommodate this user. Could someone verify that doing this will not screw something else up. Many thanks!
