如何在MySQL中指定一個常量值來顯示？

Question

我需要爲MySQL表字段（製造商）指定一個常量值。這裏是例子：我如何做到這一點的查詢

select cust_id as 'Customer Record ID', address_flag as 'Address Verified', 
oem_manuf as 'Manufacturer' 
from sales_db; 

我想把它在該領域製造商設置爲XYZ公司的查詢返回，而不必從字面上存儲XYZ公司各行中oem_manuf字段？謝謝！

select cust_id as 'Customer Record ID', address_flag as 'Address Verified', 
'XYZ Inc' as 'Manufacturer' from sales_db;
