postgresql - How to Compare two fields in laravel and postgres -

i'm trying query postgres db , sql error every time. query correct, why work?

query

apireq::where('calls','<','maxcalls')->get(); 

error

sqlstate[22p02]: invalid input syntax integer

field types both set bigint.

it's bizzare.

you need use whereraw instead of where. it's weird, gets around issue think laravel bug.

whereraw('calls < maxcalls')
