Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16445 ( https://hibernate.atlassian.net/browse/HHH-16445?atlOrigin=eyJpIjoiODMwZG... ) Re: avg() no longer works with enums ( https://hibernate.atlassian.net/browse/HHH-16445?atlOrigin=eyJpIjoiODMwZG... ) Similar to https://hibernate.atlassian.net/browse/HHH-16859 , an enum is not a numeric value, and HQL quite rightly rejects this. As I understand it, you can write avg(cast(enum as Integer)) , and I think that is a much preferable and more understandable thing. So I don’t think we should “fix” this, and instead I think we should just close this issue.
