1、一种方法是可以设置表或行的collation，使其为binary或case sensitive。在mysql教程中，对于column collate其约定的命名方法如下：

*_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

###########
# start binary collation example
###########
mysql> create table case_bin_test (word varchar(10)) character set latin1 collate latin1_bin;
query ok, 0 rows affected (0.02 sec)

mysql> insert into case_bin_test values ('frank'),('google'),('froogle'),('flickr'),('flickr');
query ok, 5 rows affected (0.00 sec)
records: 5 duplicates: 0 warnings: 0

mysql> select * from case_bin_test where word like 'f%';
+---------+
| word |
+---------+
| froogle |
| flickr |
+---------+
2 rows in set (0.00 sec)

mysql> select * from case_bin_test where word like 'f%';
+---------+
| word |
+---------+
| frank |
| flickr |
+---------+
4 rows in set (0.00 sec)
