如何使用hql在MySql中设置datetime字段

Question

I am facing an issue in inserting date in YYYY-mm-dd hh:mm:ss format in MySql DB. filed in DB is of type datetime.

I tried it :

Calendar calendar = Calendar.getInstance();
calendar.setTime(new Date());
calendar.set(Calendar.MINUTE, startMinute);
calendar.set(Calendar.SECOND,01);
Date startTime = calendar.getTime();

String hqlUpdate = "update challenge set start_time = :startTime where challenge_id =  :id";
sessionFactory.getCurrentSession().createSQLQuery(hqlUpdate)
                                 .setDate("startTime", startTime)
                                 .setInteger("id", id).executeUpdate();

Answer 1

尝试使用以下内容。

.setTimestamp("startTime", startTime);

Answer 2

Here I have specifically tried to format the date object using simpleDateFormat before passing it to the hibernate. check if this works.

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar calendar = Calendar.getInstance();
calendar.setTime(new Date());
calendar.set(Calendar.MINUTE, startMinute);
calendar.set(Calendar.SECOND,01);
Date startTime = dateFormat.parse(dateFormat.format(calendar.getTime();));

String hqlUpdate = "update challenge set start_time = :startTime where challenge_id =  :id";
sessionFactory.getCurrentSession().createSQLQuery(hqlUpdate)
                             .setDate("startTime", startTime)
                             .setInteger("id", id).executeUpdate();

如果使用setParameter()而不是setDate()它对我setParameter() ...
