Thanks, Tim. Those are some very useful DB functions for making it much
easier to query DSpace's very normalized and efficient table definitions.
I'll definitely build my custom queries around those helper functions.

Thanks, Terry! That altered query does work and provides a good, flattened

Hi Stacy,
Just as a quick FYI, some "helper SQL functions" have been gathered on the
wiki at:
https://wiki.duraspace.org/display/DSPACE/Helper+SQL+functions+for+DSpace+6
These functions make querying the DSpace 6 database a bit easier (see
examples on that page).

I imagine that there is one of 2 reasons why this did not work. My query
did not address these scenarios.
1. You have 2 schemas loaded that each have an element of title
2. You have titles in multiple languages
The following query has a placeholder for language commented out if that is

Terry, sorry for the delayed reply.
I'm getting an error with that new query:

Stacy,
I just realized that I tested the query in my DSpace 5 instance. Try the
following instead.
with recursive r_comm2coll as (
select
community_id,
collection_id
from
community2collection
union
select
cm2cm.parent_comm_id as community_id,
r.collection_id

Terry,
Thanks for the excellent advice regarding using /rest/hierarchy. I was able
to get a (long) list that could be easily cleaned up in Excel and used to
track the flattening of the hierarchy.
I only started using the REST API a few months ago, but I'm really excited
about what it can do. W
Do you have the REST API enabled? The following endpoint will provide a
dump of the hierarchy that is easy to parse.

If that does not help, here are some SQL that might help.

select
community_id,

Does anyone out there have some useful PostgreSQL queries already written
for DSpace 6.2?
I've found several sets of PostgreSQL queries that were useful for earlier
versions of DSpace, but most of them appear to be written between the
versions 1.8 and 4.x, and the database changes from the past
