java - Hibernate + Db2 + StoredProcedure call, pass NULL value -


is possible pass null value in stored procedure call using hibernate , javax.persistence?

i'm trying in way:

storedprocedurequery storedprocedure = em.createstoredprocedurequery("my_procedure_name"); storedprocedure.registerstoredprocedureparameter("p_lease_null_me", integer.class, parametermode.inout); storedprocedure.setparameter("p_lease_null_me", null); storedprocedure.execute();

but db2 tells me: "missing mandatory parameter".

any ideas?

thanmks in advance

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
