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;
    // ...
}

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 {
  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!
