I have to create tables where both have each as the foreign key . Which one should be created first DDL QUERY FOR CREATING MAINTENANCE_PROBLEM

CREATE TABLE MAINTENANCE_PROBLEM (
MP_ID int primary key, 
MP_Description varchar2(250), 
Standard_Min_Labor_Cost number(4,2), 
Standard_Min_Labor_Hours int, 
PART_ID int,
Constraint MP_PART_ID_FK foreign key (PART_ID) references Vehicle_Part (PART_ID)
);


DDL QUERY FOR CREATING VEHICLE_PART

CREATE TABLE VEHICLE_PART (
 PART_ID int primary key, 
PR_Description varchar2(250), 
PR_Cost number(4, 2), 
MP_ID int
Constraint VP_MP_ID_FK foreign key (MP_ID) references MAINTENANCE_PROBLEM (MP_ID)
);
It doesn't matter--create both of them without the foreign key constraint, and then alter the tables to add the constraints.
