MySQL中的大小写敏感整理 [英] Case Sensitive collation in MySQL

问题描述

MySQL中有任何排序规则类型支持区分大小写。
我有MySQL的所有类型的排序规则，他们都有_ci在他们的名字的末尾，因此他们是不区分大小写。提前感谢。

Is there any Collation type in MySQL which supports Case Sensitive. I had all type of collation in MySQL they all have _ci at the end of their name so they are case Insensitive collation. Thank you in advance.

推荐答案

根据MySQL手册 http://dev.mysql.com/doc/refman/5.0/en/charset-mysql.html 您应该能够以将区分大小设置为 _cs 。您可以通过执行 SHOW COLLATION WHERE COLLATION LIKE％_cs查询

According to MySQL Manual http://dev.mysql.com/doc/refman/5.0/en/charset-mysql.html you should be able to set collation to _cs for case sensitivity. You can get a list of _cs collations by executing SHOW COLLATION WHERE COLLATION LIKE "%_cs" query

经过一番研究：

显然没有 utf8 _ * _ cs （在MySQL中）。如果您需要区分大小写的整理utf8字段，您应该使用 utf8_bin 。这将弄乱 ORDER BY ，但这可以通过修正ORDER BY列COLLATE utf8_general_ci

Apparently there are no utf8_*_cs in MySQL (yet). If you need case sensitive collation for utf8 fields, you should use utf8_bin. This will mess up ORDER BY, but this can be fixed by ORDER BY column COLLATE utf8_general_ci
