替换T-SQL中的Unicode字符

前端之家收集整理的这篇文章主要介绍了替换T-SQL中的Unicode字符前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
如何仅替换字符串的最后一个字符:
select REPLACE('this is the news with a þ','þ','__')

我得到的结果是:

__是__e news wi__ a __

编辑
服务器和数据库的排序规则是Latin1_General_CI_AS

我正在运行的实际查询是REPLACE(注意,’þ’,”)其中note是一个ntext列.重点是剥离刺字符,因为该字符后来在过程中用作列分隔符. (请不要建议更改分隔符,考虑到它的使用程度,这不会发生!)

我尝试使用N前缀,即使使用test select语句,结果如下:

解决方法

þ字符(ASCII和UNICODE值254)被称为“刺”,在某些语言中直接等同于:

>此处对该字符和排序规则的说明:http://userguide.icu-project.org/collation/customization.在“复杂裁剪示例”中搜索页面(通常为Control-F),您将看到以下内容

The letter ‘þ’ (THORN) is normally treated by UCA/root collation as a separate letter that has primary-level sorting after ‘z’. However,in Swedish and some other Scandinavian languages,‘þ’ and ‘Þ’ should be treated as just a tertiary-level difference from the letters “th” and “TH” respectively.

如果您不希望þ等于th,则按如下方式强制进行二进制排序规则:

SELECT REPLACE(N'this is the news with a þ' COLLATE Latin1_General_100_BIN2,N'þ',N'__');

返回:

this is the news with a __
