Given an entityManager the following demonstrates it when it throws an exception with the failed cast: {noformat}CriteriaBuilder cb = entityManager.getCriteriaBuilder(); Expression<Long> dateDiffFunc = cb.function("DATEDIFF", Long.class, criteriaBuilder cb.literal(TemporalUnit.MINUTE), criteriaBuilder cb.currentDate(), criteriaBuilder cb.currentDate()); CriteriaQuery<Long> cr = cb.createQuery(Long.class) .select(dateDiffFunc); entityManager.createQuery(cr).getResultList();{noformat} {quote}Caused by: java.lang.ClassCastException: class org.hibernate.query.sqm.tree.expression.SqmLiteral cannot be cast to class org.hibernate.query.sqm.tree.expression.SqmDurationUnit at org.hibernate.dialect.function.TimestampdiffFunction$TimestampdiffFunctionReturnTypeResolver.resolveFunctionReturnType(TimestampdiffFunction.java:133){quote} ( https://hibernate.atlassian.net/browse/HHH-17050#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-17050#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
