在SQL Update中使用Distinct [英] Using Distinct in SQL Update

问题描述

这是我需要转换为更新的Select：

Here is the Select I need to convert to an Update:

SELECT DISTINCT f.SectionID, f.Name, v.Enabled
FROM SETTING_VALUE v
INNER JOIN SETTING s ON v.SettingID = s.SettingID
INNER JOIN LU_FIELD f ON f.FieldID = s.FieldID
WHERE v.DisplayValue LIKE '%Miami%'
AND f.ControlName LIKE '%City%'

我的尝试：

UPDATE SETTING_VALUE
SET Enabled = 0
FROM SETTING_VALUE v
INNER JOIN SETTING s ON v.SettingID = s.SettingID
INNER JOIN LU_FIELD f ON f.FieldID = s.FieldID
WHERE v.DisplayValue LIKE '%Miami%'
AND f.ControlName LIKE '%City%'

不确定如何应用Distinct

推荐答案

根据您的评论，所有匹配的行都应更新您不需要的行。只需执行以下操作即可：

Based on your comment, all of the matching rows should be updated you don't need distinct. Just execute this:

UPDATE SETTING_VALUE
SET Enabled = 0
FROM SETTING_VALUE v
INNER JOIN SETTING s ON v.SettingID = s.SettingID
INNER JOIN LU_FIELD f ON f.FieldID = s.FieldID
WHERE v.DisplayValue LIKE '%Miami%'
AND f.ControlName LIKE '%City%'

您选择的所有内容都会更新。

Everything that you saw in your select will be updated.
