Severin Hamader ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMDczMDZkYmJi... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15498?atlOrigin=eyJpIjoiMDczMD... ) HHH-15498 ( https://hibernate.atlassian.net/browse/HHH-15498?atlOrigin=eyJpIjoiMDczMD... ) Delete Query fails when NULL is being used for enum column in where clause ( https://hibernate.atlassian.net/browse/HHH-15498?atlOrigin=eyJpIjoiMDczMD... ) Change By: Severin Hamader ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) Test case will be attached shortly\! The following HQL query has been working fine in Hibernate 5.x.x: {code:sql}DELETE FROM Event WHERE (:type IS NULL OR type = :type){code} It seems, Hibernate fails to detect the enum, if I use another class (non-enum) in the same query it works. Now, with 6.1.3, I am receiving the following error: {noformat}jakarta.persistence.PersistenceException: Converting `org.hibernate.query.sqm.sql.ConversionException` to JPA `PersistenceException` : Could not determine neither the SqlTypedMapping nor the Bindable value for SqmParameter: SqmNamedParameter(type) at
