Question

我已经编写了以下代码并得到以下错误，我相信它与我如何加入国家/地区表有关，但无法解决如何解决问题。任何人都可以指出我正确的方向

Msg 4104, Level 16, State 1, Procedure cst_priceimporter, Line 37
The multi-part identifier "country.price" could not be bound.

Answer 1

更新的SET部分不应该有任何表名，你只能更新一个。此外，由于您将别名Country作为C，因此您需要使用别名

update  country 
set     price = 1 / c.price

我认为它发生了两次

消息4104，级别16，状态1，过程cst_priceimporter，第37行
