如何在列中查找单个单词（不是值）的重复项

Question

我想在我的ItemDescription列中找到单个单词的重复项。请看图片：https://imgur.com/oxuaSJT。不是重复的值，而是值中包含单个单词的重复项。可能吗？请帮我。

使用GROUP BY运算符查找出现的单词，并使用HAVING和SELECT i.ItemDescription FROM dbo.tbiitems i WHERE i.ItemDescription LIKE '%NR%' OR i.ItemDescription LIKE '%NRCONDITIONER%' OR i.ItemDescription LIKE '%CREAMBATH%' GROUP BY i.ItemDescription HAVING COUNT(i.ItemDescription) > 1 运算符查找重复项：

ItemDescription

或者如果您想查找SELECT i.ItemDescription, COUNT(i.ItemDescription) AS CountItemDescription FROM dbo.tbiitems i WHERE i.ItemDescription LIKE '%NR%' OR i.ItemDescription LIKE '%NRCONDITIONER%' OR i.ItemDescription LIKE '%CREAMBATH%' GROUP BY i.ItemDescription HAVING COUNT(i.ItemDescription) > 1 的计数并遵循 SQL规则 this subject on SO for example（感谢@Daniel E。）：
