How to compare dates in hibernate

Question

In my Data base dates are as 2012-04-09 04:02:53 2012-04-09 04:04:51 2012-04-08 04:04:51, etc, I need to retrieve data which have current date in there date field. I mean i need to match only 2012-04-09' . How can i do it using hibernate criteria.

Answer 1

Use Restrictions.between() to generate a where clause which the date column is between '2012-04-09 00:00:00' and '2012-04-09 23:59:59'

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date fromDate = df.parse("2012-04-09 00:00:00");
Date toDate = df.parse("2012-04-09 23:59:59");

criteria.add(Restrictions.between("dateField", fromDate, toDate));

Please note that all the properties used in the Criteria API is the Java property name , but not the actual column name.

Update: Get fromDate and toDate for the current date using JDK only

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
Date fromDate = calendar.getTime();

calendar.set(Calendar.HOUR_OF_DAY, 23);
calendar.set(Calendar.MINUTE, 59);
calendar.set(Calendar.SECOND, 59);
Date toDate = calendar.getTime();

criteria.add(Restrictions.between("dateField", fromDate, toDate));
