请教mssql 拉丁字母怎么转换成正常英文字母?

sunshinebean 2018-10-28 11:24:04


GEOIP库里有很多拉丁字母,类似截图里这样的.(截图里只是搜了ā相关的)。
所有的拉丁字母可以在这里看到:http://www.runoob.com/charsets/ref-utf-latin-extended-a.html

有没有什么办法可以让select出来的结果是正常的英文字母?比如Trikāta->Trikata

我有尝试过根据拉丁字母表建一个表,一个个去替换...但是mssql好像不能识别拉丁字母的大小写..我用collate Chinese_PRC_CS_AS测试正常的英文字母是可以的,但是测试拉丁字母搜的明明是Ā,但是出来的结果都是ā
