数据来自通过 Visual Studio Windows 应用程序从 Excel 和 d 转换而来的 csv 文件.数据最初是..."，但我认为 word/excel 可能将其归类为一个字符(而不是 3 个单独的.").当我的应用程序从 CSV 文件读取原始字符串时，它(无意中)在将数据提交到数据库之前将..."替换为"".
The data came from a csv file converted from Excel an d via a Visual studio windows app. The data originally was '...' but I think perhaps word/excel classed this as one character (rather than 3 separate '.'). When my application read the original string from CSV file it (unintentionally) replaced the '...' with '�' before submitting the data into the database.
请帮忙

我不得不转换为二进制.65500 以上的所有 unicode 字符都需要这样做，因为正常的 REPLACE() 不起作用.
I had to convert to binary. All unicode characters above 65500 require this as normal REPLACE() doesn't work.
UPDATE S
SET S.Offering_Details = REPLACE(S.Offering_Details, nchar(65533) COLLATE Latin1_General_BIN, '...')
FROM tblSacrifices S
