JPA查询引发异常

Question

I am trying to save one record into the mysql 5.1 db. When I use entity manager.persist() or merge() method then it is not even saving a record to db and when I try to use native insert statement like this the it throws exception

Query query = entityManager.createNativeQuery("insert into Employee(firstName,lastName,phone,email) values(?,?,?,?);");
    query.setParameter(1, employee.getFirstName());
    query.setParameter(2, employee.getLastName());
    query.setParameter(3, employee.getPhone());
    query.setParameter(4, employee.getEmail());

Exception thrown from the above query is

org.springframework.orm.jpa.JpaSystemException: org.hibernate.exception.GenericJDBCException: could not execute native bulk manipulation query; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: could not execute native bulk manipulation query

Please help me !!!!

Thanks

While I can't immediately help you with the query, because you are most probably omitting an important part of the stacktrace, I have a solution:

Don't use INSERT HQL queries. This is not the way JPA is supposed to work. Instead create a new Emplyee() object, which should be an @Entity , and set its attributes, then entityManager.persist(employee) .

In order for this to work, you need a running transaction. entityManager.getTransaction().being() would start one, and entityManager.getTransaction().commit() would commit it.
