关于查询字段内容无法区分大小写问题

查询大写但是小写也显示
怀疑字符集问题

最后查询是字符集校对问题
Mysql collate规则：
*_bin: 表示的是binary case sensitive collation，也就是说是区分大小写的
*_cs: case sensitive collation，区分大小写
*_ci: case insensitive collation，不区分大小写
修改校对规则
root@localhost 20:44: [pwb_inn]> ALTER TABLE sys_account_login CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_cs;
ERROR 1273 (HY000): Unknown collation: 'utf8_general_cs'
5.6不支持utf8_general_cs
root@localhost 20:44: [pwb_inn]> ALTER TABLE sys_account_login CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 0 rows affected (0.01 sec)
Records: 0 Duplicates: 0 Warnings: 0
root@localhost 20:44: [pwb_inn]> ALTER TABLE sys_account_login CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;

root@localhost 20:45: [pwb_inn]> select * from sys_account_login where corp_code='TEST';
