更新Access的语法 [英] Update syntax for Access

问题描述

我需要根据与另一个表的匹配来更新一个字段(当前为空).这应该很简单，但是我的语法是错误的.

I need to update a field (which is currently empty) based on a match with another table. This should be simple, but my syntax is wrong.

在SQLServer 2005中，语法为

In SQLServer 2005, the syntax would be

UPDATE Facilities-NOID
SET Facilities-NOID.ID = Facilities-ID.ID
FROM Facilities-NOID, Facilities-ID
WHERE [Facilities-ID].[Structure ID] = [Facilities-NOID].[Structure ID];

访问不喜欢那条FROM行，但是如果我忽略它，它需要每个ID.这应该很简单，但是我没有在MS帮助中看到Update语法.

Access doesn't like that FROM line, but if I leave it out, it wants each ID. This should be simple, but I'm not seeing it in the MS help on the Update syntax.

推荐答案

我认为这是您想要的:

UPDATE Facilities-NOID 
INNER JOIN Facilities-ID ON Facilities-NOID.[Structure ID] 
    = Facilities-ID.[Structure ID]
SET Facilities-NOID.ID= Facilities-ID.ID

您正在根据设施ID中出现的结构ID匹配来更新设施NOID.

You are updating Facilities-NOID based on a match on Structure ID occurring in Facilities-ID.
