How to write the criteria query for NVL in Hibernate

Question

I have column c in Table A and Table B,How do i write criteria query for a where clause:

select * from A a,B b where Ac=NVL(B.c,'Constant');

Please help?

Answer 1

The NVL function behaves similarly to COALESCE , the latter which is natively supported by Hibernate query language. So, you may use COALESCE instead:

select * from A a, B b where A.c = COALESCE(B.c, 'Constant');
