create table salesman_96(snum number(4),sname varchar(25),city varchar(20),comm varchar(10));

create table customer_96(cnum number(4),cname varchar(25),city varchar(20),rating number(4),snum number(4));

create table orders_96(onum number(4),amount float,odate date,cnum number(4),snum number(4));

Creating Table for Orders

insert into orders_96 values(3001,'18.69','10-mar-97',2008,1007);
insert into orders_96 values(3003,'767.19','10-mar-97',2001,1001);
insert into orders_96 values(3002,'1900.10','10-mar-97',2007,1004);

insert into orders_96 values(3006,'1098.16','10-mar-97',2008,1007);
insert into orders_96 values(3009,'1713.23','10-apr-97',2002,1003);
insert into orders_96 values(3007,'75.75','10-apr-97',2004,1002);

insert into orders_96 values(3011,'9891.88','10-jun-97',2006,1001);

Creating Table for Salesman
insert into salesman_96 values(1001,'piyush','london','12%');
insert into salesman_96 values(1002,'sejal','surat','13%');
