The following program is a generated view based on each table association
Drop View A_cust
CREATE View a_cust as select Customer_code,customer_name,customer_full_name,employee_code,employee_name,d.address,d . Telephone,e.contact,a_c.id from CUSTOMER A
Left join Customer_sales b on a.customer_business_id = b.customer_id

Left join customer_address D on b.customer_business_id = d.customer_business_id
Left join Customer_contact e on b.customer_business_id = e.customer_business_id
where a.approvestatus = ' Y '

Insert into A_c (GH) Select Employee_code from EMPLOYEE

SELECT * FROM A_c

Select from a_cust where ADDRESS was not null
Select from CUSTOMER where customer_code = ' 0080 '
Select *from customer_sales where customer_id = ' f16dd932-0155-4a9a-4fe9-13bf5cf9277d '
