问题描述
这是我需要转换为更新的选择:
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%'
