Question

I am using Hibernate 4 on DB2 v9 with JPA 2’s CriteriaBuilder to build a query on the fly that can filter by date. The relevant part of the predicate is…

criteriaBuilder.greaterThan(myRoot.get(MyEntity_.myDate), aDateValue)

My mapping is pretty straight forward…

@Column(name="MY_DATE")
@Temporal(value = TemporalType.DATE)
public Date getMyDate() {
    return myDate;
}

The column on the table is of type DATE. The error I get when I run a query with this restriction is…

org.hibernate.exception.DataException: DB2 SQL Error: SQLCODE=-181, SQLSTATE=22007

If I take the generated SQL and run it in a stand alone SQL editor, it runs fines. I have tried changing to TemporalType.TIMESTAMP with no luck. I have double-checked that the bind input is valid at runtime as well.

Answer 1

Turns out that if aDateValue is of type java.sql.Date rather than java.util.Date the error goes away.
