MySQL 中是否有任何支持区分大小写的排序规则类型.我在 MySQL 中有所有类型的排序规则，它们的名称末尾都有 _ci，因此它们是不区分大小写的排序规则.
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.
根据 MySQL 手册 http://dev.mysql.com/doc/refman/5.0/en/charset-mysql.html 你应该能够将排序规则设置为 _cs区分大小写.您可以通过执行 SHOW COLLATION WHERE COLLATION LIKE "%_cs" 查询来获取 _cs 排序规则的列表
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
经过一些研究:
显然 MySQL 中没有 utf8_*_cs(目前).如果您需要 utf8 字段区分大小写的排序规则，您应该使用 utf8_bin.这会弄乱ORDER BY，但这可以通过ORDER BY column 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
