使用更新命名查询时，如何解决JPA / Hibernate中的“封装表达式丢失”错误？

Question

I am getting excapsulated expression missing issue while writing named query.

int a = em.createQuery("UPDATE MyProsess d SET d.updateDate = current_date() WHERE d.personId = :personId")

Even when i pass multiple parameters to above query it gives some new errors. For example

int a = em.createQuery("UPDATE MyProsess d SET d.updateDate = current_date(), d.status=:stat WHERE d.personId = :personId")

Anyone could suggest how to resolve this issue?

Ok I got it. Please replace current_date() with "current_date" remove the brackets I think HQL is not able to recognize it with brackets. Now in your Entities you have java.util.Date while current_date will return java.sql.Date this needs to be converted. Mark the attribute updateDate with @Temporal(TemporalType.Date) annotation to ensure smooth conversion.
