mysql - 如何在 MySQL 中指定一个常量值进行显示？

Question

我需要为 MySQL 表的字段（制造商）指定一个常量值。这是示例：

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

我希望它在字段制造商设置为 XYZ Inc 的查询中返回。如何在查询中执行此操作，而不必在 oem_manuf 字段的每一行中逐行存储 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;
