I created two tables like this: create table customer(SID int,name varchar(20),primary key(SID)); create table orders(OID int,O_Date date,customer_SID int,primary key(OID),Foreign key(customer_SID) references customer(SID) on delete cascade on update cascade);
And inserted values into it.but when i deleted a row from customer which has reference in orders it didn't showed any error..it deleted the value in customer table while it's reference in orders remain unchanged.Plz help me in solving this.
