[OPEN-ILS-GENERAL] Moving/Renaming Volumes - was Deleting parts map for deleted copies

[Josh Stompro]

Just to reply to myself, I found the asset.merge_record_assets database function which seems to cover all the bases, looking through that helped me confirm that what I'm doing will work.

Blake or anyone else,

I've finished cleaning up the parts and that went well.  Now I'm looking at a list of ~300 volumes (asset.call_number) that have been added with the wrong label.  And some of them have several variations of the wrong label for the same record and owning lib, so I cannot just rename them all, I need to transfer some copy's to different volumes after the first occurrence has been renamed.  There are enough of them that I don't want to use the staff client since that means looking up 300 volumes.

Are there any gotchas to moving copies to different volumes on the same record?  I don't think I need to worry about parts since I'm not moving to a different bib record with this fixup.

Would something like this cover it?
  Volume_id is the current call_number.id and existing_volume is the volume on the same record to move to.

    UPDATE asset.copy SET call_number = existing_volume WHERE call_number = volume_id and deleted=false;
    UPDATE action.hold_request SET target=existing_volume WHERE target = volume_id and hold_type = 'V';
    UPDATE action.aged_hold_request SET target=existing_volume WHERE target = volume_id and hold_type = 'V';
    UPDATE asset.call_number set deleted=true where id = volume_id;

I don't see any asset.uri_call_number_map entries to worry about. Or any asset.call_number_note entries.  I've looked through the asset.volume.batch.transfer method and Cat/Merge.pm , and I don't see anything else that seems to apply.

Thanks

Josh,

Watch out for 'P' level holds targeting your monograph_part ID's

Hello, I'm working on a parts cleanup project(EG 2.8), and I'm wondering if there are any problems with deleting entries from asset.copy_part_map for all deleted copies?  I want to purge all the parts that are not being used before I start making fixes.  Once I remove the part_map I can remove the biblio.monographic_parts that are not currently used by any copies or holds.  Are there any pitfalls that you know about?

Thanks
Josh
