我有以下方法来更新3个表中的列。记录在第一个表（Ref：query2）中成功更新，但在更新表2和表3中的“modifiedDate”列时出错。同一列在表1中成功更新。
@Override
public void updateResult(int candidateID, String newResult, int totalScore, Date today, String newUploadState) {
System.out.println("Updating the result to DB");
Session currentSession = sessionFactory.getCurrentSession();
String query1 = "SELECT p.ro FROM PersonalInfo p WHERE p.candidateID =:id";
String ro = currentSession.createQuery(query1).setParameter("id", candidateID).list().get(0).toString();
String query2 = "UPDATE PersonalInfo as p set " +
"p.score = :score," +
"p.result = :result, " +
"p.modifiedDate = :modifiedDate, " +
"p.modifiedBy = :modifiedBy, " +
"p.uploadState = :uploadState " +
"where p.candidateID = :id";
Query thequery2 = currentSession.createQuery(query2);
thequery2.setParameter("id", candidateID);
thequery2.setParameter("score", totalScore);
thequery2.setParameter("result", newResult);
thequery2.setParameter("modifiedDate", today);
thequery2.setParameter("modifiedBy", ro);
thequery2.setParameter("uploadState", newUploadState);
thequery2.executeUpdate();
String query3 = "UPDATE Address as a set " +
"a.modifiedDate = :modifiedDate, " +
"a.modifiedBy = :modifiedBy, " +
"a.uploadState = :uploadState " +
"where a.candidateID_FK = :id";
Query thequery3 = currentSession.createQuery(query3);
thequery3.setParameter("id", candidateID);
thequery3.setParameter("modifiedDate", today);
thequery3.setParameter("modifiedBy", ro);
thequery3.setParameter("uploadState", newUploadState);
thequery3.executeUpdate();
String query4 = "UPDATE Fitness as f set " +
"f.modifiedDate = :modifiedDate, " +
"f.modifiedBy = :modifiedBy, " +
"f.uploadState = :uploadState " +
"where f.candidateID_FK1 = :id";
Query thequery4 = currentSession.createQuery(query4);
thequery4.setParameter("id", candidateID);
thequery4.setParameter("modifiedDate", today);
thequery4.setParameter("modifiedBy", ro);
thequery4.setParameter("uploadState", newUploadState);
thequery4.executeUpdate();
}
以下是来自控制台的堆栈跟踪，显示与将日期转换为String相关的错误。所有3个表中“ModifiedDate”列的“数据类型”为“datetime”。
Hibernate: update personal_info set Score=?, Result=?, ModifiedDate=?, ModifiedBy=?, UploadState=? where CandidateID=?
Hibernate: update address_details set ModifiedDate=?, ModifiedBy=?, UploadState=? where candidateID_FK=?

答案 0 :(得分：0)
根据列类型
使用以下其中一项thequery3.setParameter("modifiedDate", today, TemporalType.TIMESTAMP);
或者
thequery3.setParameter("modifiedDate", today, TemporalType.DATE);
对所有查询使用相同的内容 - thequery1， thequery2， thequery3， thequery4
