can anyone help me to check the relation table of the database.

please post your question in full text
even i can't understand your question, so how can i help you?
please post your question again with some description of your question.

thanks

I looked at your SQL statements and it all looks fine, as far as I can tell. I did have to translate your SQL to a dialect I was more familiar with, but once I got all that fixed up, I didn't have any problems building the database and populating the tables.

There is one question about that PROMOTION table. Not sure if it's supposed to have referential integrity to anything. If so, it needs some work to get it to relate to anything.

If there's an actual question here, please elaborate.

Draw a complete ER-diagram/Model for the PIZZA delivery Database which consists of topping, Pizzatopping, Pizza, Pizza order, Customer tables.

----------------------------------------------

drop table pizza;
drop table topping;
drop table pizzatopping;
drop table pizzaorder;
drop table customer;

create table pizza
(
  pizzaID   number,
  pizzaname varchar2(30),
  basecost  number(4,2),
  primary key   (pizzaID)
);

create table topping
(
  toppingID number,
  topping   varchar2(10),
  toppingtype   varchar2(5),
  toppingcost   number(4,2),
  primary key   (toppingID)
);

create table pizzatopping
(
  pizzaID   number,
  toppingID number,
  primary key (pizzaID, toppingID)
);

create table pizzaorder
(
  orderID   number,
  customerID    number,
  pizzaID   number,
  orderdate date,
  quantity  number,
  primary key   (orderID)
);

This has nothing to do with your earlier question. It also looks like a homework assignment.
