如何在MySQL中指定显示的常量值？

Question

我需要为MySQL表的字段（制造商）指定一个常量值。这是一个例子：

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

我希望在查询中返回字段制造商设置为XYZ Inc.如何在查询中执行此操作而不必在每行中为oem_manuf字段存储XYZ Inc？谢谢！

Answer 1

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