SQL to JPA [message #735185]

Hi.
In my database I have a table with 3 fields: field_1, field_2, field_3 and generated entity for that table. I need to implement something like this in EclipseLink:

Select (field_1/field_3) as field_1, (field_2/field_3) as field_2, field_3 from table;

Of course this is simplified example. Is there any way to do this without NativeQuery?

thanks for any help

This should work in JPQL, did you try it? You will get back an Object[] of the three values.

Select (t.field_1/t.field_3), (t.field_2/t.field_3), t.field_3 from Table t
