I have problem with HQL where I am setting the query parameters. One of them is Date. When I debug the code there is Date with time entering the method. I set the parameter using setParameter(timestamp, new Timestamp(date.getTime())) or query.setTimestamp...etc etc I used many combinations...
When I use p6spy to examine the SQL comming from app to the DB there is only '29-Jan-21' or other date without time.
I am using hibernate 5.1.0 final and postgre DB. I'll be glad for any help.
Example:
Query query = getSessionFactory().getCurrentSession().createQuery("SELECT user FROM UserEntity cr WHERE user.userStatus.id = :statusId AND :timestamp >= user.valid_to");
This is how I tried to set the timestamp parameter:
query.setParameter("timestamp", new Timestamp(date.getTime()));
query.setParameter("timestamp", date, TimestampType.INSTANCE);
query.setTimestamp("timestamp", date);
query.setTimestamp("timestamp", new Timestamp(date.getTime()));
Problem is that the generated SQL replace timestamp by '29-Jan-21' or other date I choose but without time. The date parameter comes to the method from UI and it contains full date with time.

I'm using Java 8 with Spring's JdbcTemplate and Oracle 12.1,
I want to update record and get the exact time record was updated
jdbcTemplate.update(UPDATE_SQL, null);
Currently it returns (int) the number of rows affected, but I want the exact updated date
Must I send a new request to get current time which may be inaccurate?
More exact will be to save in column updated date, but then to execute another SQL
Is there another option to get updated date in one query?
Obviously, I don't want to use get date from code also (as new Date()) also because server time is/can be different than DB Time
You decided to use JDBCTemplate most probably to simplify the code in comparison to plain JDBC.
This particular problem IMHO makes the plain JDBC solution as proposed in other answer much simpler, so I'd definitively recommend to get the database connection from JDBCTemplate and make the insert in a JDBC way.
The simplest solution using JDBCTemplate that comes to my mind is to wrap the insert in a PROCEDURE and return the timestamp as an OUT parameter.
Simple example (Adjust the time logik as required)
create procedure insert_with_return_time (p_str VARCHAR2, p_time OUT DATE) as
BEGIN
insert into identity_pk(pad) values(p_str);
p_time := sysdate;
END;
/
The call is done using SimpleJdbcCall
SimpleJdbcCall jdbcCall = new SimpleJdbcCall(jdbcTemplate).withProcedureName("insert_with_return_time");
SqlParameterSource params = new MapSqlParameterSource().addValue("p_str", str);
Map<String, Object> out = jdbcCall.execute(params);
The Map contains the returned value e.g. [P_TIME:2019-10-19 11:58:10.0]
But I can only repeat, in this particular use case is IMHO JDBC a rescue from JDBCTemplate;)
You're right that passing new Date() would store the server time rather than the DB time.
To store the DB time you can set your timestamp to the DB system timestamp systimestamp then you could run a query to retrieve that row and its updated timestamp.
If you want to update the row and get the updated timestamp in a single execution then you could do the following using RETURNING INTO where TimestampUpdated is your column name:
Connection con = ...;
String sql = "UPDATE TableName SET <updates> , TimestampUpdated = systimestamp RETURNING TimestampUpdated INTO ?";
CallableStatement statement = con.prepareCall(sql);
statement.registerOutParameter(1, Types.TIMESTAMP);
int updateCount = statement.executeUpdate();
Timestamp timestampUpdated = statement.getInt(1);
System.out.println("Timestamp Updated = " + timestampUpdated);

I am using JPA Repository.
I need to search records by ID and Current Date.
Presently I am using
List<Allocation> findByIdAndDate(String Id , Date date);
I am sending current date at the time of method calling
Just like we have method
List<Entity> findByIdAndFlagTrue(String Id)
which by default searches for a true flag,
So if there is any method of query building which searches for current date
I'm making a library project in Java that is supposed to record data about members, books, users and borrowings. When I create a new object of the class Borrowing the system automatically notes the IssueDate.
The problem happens when I try to make a record of the book being returned with and UPDATE SQL QUERY and record the ReturnDate.The query works but in DB in the corresponding field I always get 30/12/1899 as a ReturnDate.
The SQL query goes like this:
UPDATE Booking SET Returned = 1, ReturnDate = "+ sdf.format(getReturnDate()) +" WHERE BookingID =" + getBookingID()
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
setReturnDate(new Date());
I decided to format it to String and format dd/mm/yyyy because that is the format Access recognizes when I enter it manually and it worked with all other queries (like creating a new Booking and IssueDate) in the project and it enters the real date.
I have already tried using java.sql.Date instead, switching to the US format (mm/dd/yyyy) and using # (hash marks) at the beginning and the end of the date string and none of those worked.
Do you have any other ideas?
Consider using a PreparedStatement instead, see Using Prepared Statements for more details
Instead of setting the "text" of the query, use setDate of the PreparedStatement and let the JDBC driver work it out
I have an entity with a date field (java.util.Date). Normally the date is saved as for example 2012-10-19 21:29:03.000. My database is MySQL.
Now I need to query the database, through JPQL, using strictly the date portion, i.e., 2012-10-19. How would I do that?
That can be done by giving TemporalType when setting parameter:
Date param ...
Query q = em.createQuery("SELECT a FROM EntityA a WHERE a.someDate > :param");
q.setParameter("param", param, TemporalType.DATE);
