(Note that I do agree that the error here is quite ugly.)

I guess it sorta might make sense for some ORDINAL mappings, but even that is pretty doubtful. So I guess my vote would be to disallow this with a more meaningful error, but I would not strongly object to allowing it only for ordinal-mapped enums.

[JIRA] (HHH-16858) Can't compare test expression of type [BasicSqmPathSource(type : Enum)] with element of type [basicType@5(java.lang.Integer,4)]

by Jonas Gernot Steinke (JIRA)

Jonas Gernot Steinke ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=712020%... ) *commented* on HHH-16858 ( https://hibernate.atlassian.net/browse/HHH-16858?atlOrigin=eyJpIjoiYTk3Zm... ) Re: Can't compare test expression of type [BasicSqmPathSource(type : Enum)] with element of type [basicType(a)5(java.lang.Integer,4)] ( https://hibernate.atlassian.net/browse/HHH-16858?atlOrigin=eyJpIjoiYTk3Zm... ) The comparison with < in this example is only to show that comparison operators ( = , < , > , >= , <= , <> ) do not work in this case. In the example I use EnumType.ORDINAL , in the other case of EnumType ( https://docs.jboss.org/hibernate/orm/current/userguide/html_single/Hibern... ) EnumType.STRING a similar error occurs: Error interpreting query [SELECT b FROM ItemB b WHERE b.type = 'B2']; this may indicate a semantic (user query) problem or a bug in the parser [SELECT b FROM ItemB b WHERE b.type = 'B2'] Can't compare test expression of type [BasicSqmPathSource(type : Enum)] with element of type [basicType(a)15(java.lang.String,12)] The question is, why does it work with ItemA: public interface ItemARepository extends JpaRepository<ItemA, Long >, JpaSpecificationExecutor<ItemA> { @Query( "SELECT a FROM ItemA a WHERE a.type < 1" ) List<ItemA> findAllByTypeA2(); } https://github.com/JGSteinke/hibernate-test/blob/main/src/main/java/de/hi... As I wrote before, it has only stopped working since the Hibernate update. My guess is that in case A the enum is compared depending on the EnumType ( EnumType.ORDINAL as Integer or EnumType.STRING as String) and in case B this does not happen. The question of sense of compare enums using < is not at issue here, but I would like to discuss it briefly. In this way you can, for example, find all entries that precede a certain status.

[JIRA] (HHH-16860) OneToMany with inherited classes on both sides

[JIRA] (HHH-16790) Performance issue when retrieving a large bulk of entity in bidirectionnal association

by Thomas Herth (JIRA)

Thomas Herth ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=712020%... ) *commented* on HHH-16790 ( https://hibernate.atlassian.net/browse/HHH-16790?atlOrigin=eyJpIjoiMTA2NT... ) Re: Performance issue when retrieving a large bulk of entity in bidirectionnal association ( https://hibernate.atlassian.net/browse/HHH-16790?atlOrigin=eyJpIjoiMTA2NT... ) I uploaded hibernate6-eager-fetching-performance-issue.zip with two sample projects, one using Spring Boot 3 and Hibernate 6 and the other using Spring Boot 2 and Hibernate 5. Even the domain classes can be optimized - I detected two unnecessary eager fetchings - we can see that Hibernate 6 is significantly slower than Hibernate 5 when fetching the collections. The log files included in the ZIP file show two runs with 200 C1Sets. First the run of H6Sample creates the C1Sets and then lists them. Second the run of H5Sample uses the same data to list all C1Sets. Time needed for listing: 40 seconds vs 1.5 seconds using Postgres 13 H6Sample: http://localhost:8086/c1sets http://localhost:8086/swagger-ui/index.html#/c-1-set-controller/listAll H5Sample http://localhost:8085/c1sets http://localhost:8085/swagger-ui/index.html#/c-1-set-controller/listAll In BootstrapService the number of C1Sets to be created can be changed. Maybe you want more C1Sets e.g. when using using an H2 database for the tests - or less. Using Postgres 20 C1Sets are enough to see a difference. I hope this helps finding a solution for this issue.
