Hi Markus,

You could create a derived attribute in your model for the truncated value, but it would calculate that every time you fetch rows as well.

I can live with raw rows but would have been great if anyone knows

Need to find objects satisfying the following condition:

CHECK_IN_TIME must be at least on the same day or later than REQUESTED. Both values are stored as NSTimestamp with a 15 minutes precision.

In Postgres I would write

...where date_trunc('day', CHECK_IN_TIME) >= date_trunc('day', REQUESTED)

How can I create a qualifier for this? Is this possible at all or do I have to resort to raw rows for SQL?

Thanks
