Hibernate Criteria for Time > 0

Question

I am to fix an older project, in which there is a database query gone wrong. In the Table, there is a field

viewTime TIME NOT NULL DEFAULT 0

I need to filter out the rows that actually have 0 as their viewTime :

Criteria query = /* create criteria */;
query.add(Restrictions.gt("viewTime", 0));

However, since viewTime is defined as a Date:

@Temporal(TemporalType.TIME)
private Date viewTime;

I get a casting exception. On the other hand, I have no idea how to create a valid Date object that represents time 0 . I can't change the type of the field as well for this.

Any way I can express viewTime > 0 in this Criteria object?

Answer 1

I think you have to compare date object with (00/00/00) but the any API will not produce DATE value like it.

This might your solution convert to null refer this link

Answer 2

It seems to me, that you can try such construction:

Criteria query = /* create criteria */;
query.add(Restrictions.gt("viewTime", new Date(0)));
