Markus Hofstetter ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-15777 ( https://hibernate.atlassian.net/browse/HHH-15777?atlOrigin=eyJpIjoiMTBlZG... ) Re: wrong column type expected for audit table keys ( https://hibernate.atlassian.net/browse/HHH-15777?atlOrigin=eyJpIjoiMTBlZG... ) I also encountered this Problem. Envers ignores the @JdbcTypeCode Annotation. I have a @MappedSuperclass that defines an id like this: @Schema @Id // @Type(value = org.hibernate.type.UUIDCharType.class) // this was the way to do it in hibernate 5 @JdbcTypeCode(SqlTypes.VARCHAR) // hibernate 6 way @Column(nullable = false, updatable = false, length = DB_UUID_LENGTH) @NonNull private UUID id = UUID.randomUUID(); When exporting the schema through hibernate this creates the actual Entity Tables correctly but envers tries to generate a binary column. The DB dialect I am using is mariadb. CREATE TABLE IndexPerson ( id VARCHAR(36) NOT NULL, userErstellt_id VARCHAR(36) NOT NULL, userMutiert_id VARCHAR(36), name VARCHAR(255), vorname VARCHAR(255) NOT NULL, PRIMARY KEY (id) ) ENGINE = InnoDB; CREATE TABLE IndexPerson_AUD ( id BINARY(36) NOT NULL, userErstellt_id BINARY(36), userMutiert_id BINARY(36), name VARCHAR(255), vorname VARCHAR(255), PRIMARY KEY (REV, id) ) ENGINE = InnoDB; As you can see varchar(36) is used for the "real" entity table as requested. However the audit Table is generated with a binary column which obviously will not work.
