Savio, thank you for clarifying that you are in DSpace 5.

The following code appears to document the migration of community.name from DSpace 4 to DSpace 5.

https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/resources/org/dspace/storage/rdbms/sqlmigration/postgres/V5.0_2014.09.26__DS-1582_Metadata_For_All_Objects.sql#L133-L141

DSpace 5 introduced "metadata for all objects" and collection.name appears to be stored as a metadatavalue of "title".

回答2:

The collection name is stored in the collection table. It is linked to the item table via item.owning_collection and collection2item.

select collection.name 
from collection 
inner join item on owning_collection=collection_id
where item_id=1
