JPA @NamedQuery with bitwise AND (&) as criteria

Question

does anyone know how to use bitwise AND (&) as criteria for a JPA NamedQuery without having to use a @NamedNativeQuery?

I\'m storing status bits in a field.

Answer 1

Bitwise AND is not part of JPQL. But...

Can be use 2 rules:

1. division by 2^х will shift the bits right by x (exemple 1011010/1000=1011)
2. z mod 2 = 1 if right bit is 1 (exemple 1011 mod 2 = 1)

try

SELECT v FROM ViewProductsList v WHERE MOD(v.statusId/16 , 2) = 1

Answer 2

'Bitwise AND' is not part of JPQL. Native query is the portable way to go.
