How to query LocalDateTime with LocalDate?

Question

I\'ve got a class which contains an atttribute of java.time.LocalDateTime type.

public class MyClass{
    // ...
    private LocalDateTime fecha;
    // ...
}


        

Answer 1

Zombie Thread, but thought I'd throw my solution into the ring.

I had a similar issue, I ended up using a Hibernate @Formula

For example:

class MyClass {

  private LocalDateTime fecha;

  /* fecha referenced within the annotation should be the column name. 
   * So, if it's different the Java field name (i.e. fecha_dtm or something), 
   * make sure to use it.
  */
  @Formula("CAST(fecha as DATE)") 
  private LocalDate fechaDate;

}

Then your repository:

public interface IRepository extends CrudRepository<MyClass, UUID> {
  deleteByFechaDate(LocalDate fecha); // note it's FechaDate, not Fetcha
}

Try to stick to ANSI SQL compliant functions (CAST is SQL-92 compliant, so pretty widely accepted) to keep things consistent across database implementations. However, DB specific functions can be used, you'll just lose portability.

Hopefully this helps you!

Answer 2

I had a similar question today (I was making SELECT, not a DELETE) and after posting it on here, I came up with two solutions:

@Query(value = "DELETE FROM MyClass mc WHERE DATE(fecha) =:fecha", nativeQuery = true)
public void deleteByFecha(LocalDate fecha);

Alternatively, following Cepr0's answer, I tested with success his solution:

default void deleteByFecha(LocalDate fecha) {
    deleteByFechaBetween(fecha.atStartOfDay(), fecha.plusDays(1).atStartOfDay());

}

void deleteByFechaBetween(LocalDateTime from, LocalDateTime to);

Answer 3

LocalDateTime and LocalDate are incompatible types as is (although they both implement Temporal, in case you can work with that).

Otherwise, you have a LocalDateTime#toLocalDate conversion method available.

Answer 4

Try this (not tested):

public interface IRepository extends CrudRepository<MyClass, UUID> {
    // ...
    default void delByFecha(LocalDate fecha) {

        deleteByFechaBetween(fecha.atStartOfDay(), fecha.plusDays(1).atStartOfDay());

    }

    void deleteByFechaBetween(LocalDateTime from, LocalDateTime to);
    // ...
}

Answer 5

I know that this one is a old issue, but for the future, who is with the same problem can use this solution:

 default void delByFecha(@RequestParam(name = "date") @DateTimeFormat(iso = ISO.DATE) LocalDate date)

It's works perfectly!
