How to search current date in Timestamp field of MYSQL using Hibernate Named Query (HQL)?

I tried to pass date using following way but unable to succeed. dateAnswered is field which stores date as 2017-09-13 00:00:00.

Can anyone tell where i am getting wrong:

Way 1: SetParameter

@NamedQuery(name = "findAnswar", query = "SELECT a FROM Answar a WHERE (a.dateAnswered = :currentDate )"

Try 1: 
super.em.createNamedQuery( "findAnswar" , Answar .class ).setParameter( "currentDate", new Date() ); //Not receive any data

Try 2: 
Date date = new Date();
date.setHours(0);
date.setMinutes(0);
date.setSeconds(0);
super.em.createNamedQuery( "findAnswar" , Answar .class ).setParameter( "currentDate",  date) //Not receive any data

Way 2: Set inbuilt parameters

@NamedQuery(name = "findAnswar", query = "SELECT a FROM Answar a WHERE (a.dateAnswered = current_date() )") //NOT WORKS

It works if i do add Temporal to getter:

@Column(name = "DATE_ANASWERED")
@Temporal(TemporalType.DATE)
 public Date getDateAnswered () {
  return dateAnswered ;
}

BUT IT GIVES another issue : Caused by: org.hibernate.HibernateException: Wrong column type in db.ANSWAR for column DATE_ANASWERED. Found: datetime, expected: date

 @NamedQuery(name = "findAnswar", query = "SELECT a FROM Answar a WHERE (a.dateAnswered = current_date )") //NOT WORKS - JPA errors

Even in previous answers of Stackoverflow i am not able to find any related solution. Can anyone help in fixing the same using Named Query only?

Able to achieve it doing following changes to named query and it worked like charm:

"SELECT a FROM Answar a WHERE cast(a.dateAnswered as date) = current_date()

As underlying type is datetime so so we need to cast it to date to use current_date()

You need to specify the temporal type.

Way 1

super.em.createNamedQuery("findAnswar", Answar.class)
     .setParameter("currentDate", new Date(), TemporalType.TIMESTAMP);

Way 2

@Column(name = "DATE_ANASWERED")
@Temporal(TemporalType.TIMESTAMP)
    public Date getDateAnswered () {
    return dateAnswered ;
}
