[JIRA] (HHH-16859) max() doesn't work with Enums

by Gavin King (JIRA)

Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16859 ( https://hibernate.atlassian.net/browse/HHH-16859?atlOrigin=eyJpIjoiZmZjMG... ) Re: max() doesn't work with Enums ( https://hibernate.atlassian.net/browse/HHH-16859?atlOrigin=eyJpIjoiZmZjMG... ) I think you have a pretty fundamental misunderstanding here. You’re asking us to do work to change something for you. So it’s you who needs to provide good arguments for a change, not me who is required to provide good arguments to do no work and make no change. Oh, unless you’re a customer and are paying for support. Are you?

[JIRA] (HHH-16859) max() doesn't work with Enums

by Michał Maliszewski (JIRA)

Michał Maliszewski ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5ad7619... ) *commented* on HHH-16859 ( https://hibernate.atlassian.net/browse/HHH-16859?atlOrigin=eyJpIjoiMGVkYT... ) Re: max() doesn't work with Enums ( https://hibernate.atlassian.net/browse/HHH-16859?atlOrigin=eyJpIjoiMGVkYT... ) That’s a poor argumentation. The enum stored as a String “VALUE_X” is also not self-descriptive. I know plenty of real programs where the DB is not open for 3rd parties directly, instead the data access is provided by the API.

On the other hand, any non-Java-programmer who has to look at your database will hate you for using this mapping. (And the performance difference is trivial and irrelevant in any real program.)
