1、一種方法是可以設置表或行的collation，使其為binary或case sensitive。在MySQL中，對于Column Collate其約定的命名方法如下： 

*_bin: 表示的是binary case sensitive collation，也就是說是區分大小寫的 
*_cs: case sensitive collation，區分大小寫 
*_ci: case insensitive collation，不區分大小寫 


########### 
# 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) 

########### 
# End 
########### 

2、另外一種方法 

########### 
# Start case sensitive collation example 
########### 

mysql> create table case_cs_test (word VARCHAR(10)) CHARACTER SET latin1 COLLATE latin1_general_cs; 
Query OK, 0 rows affected (0.08 sec) 

mysql> INSERT INTO case_cs_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_cs_test WHERE word LIKE 'F%'; 
+---------+ 
| word | 
+---------+ 
| Frank | 
| FlicKr | 
+---------+ 
4 rows in set (0.00 sec) 

mysql> SELECT * FROM case_cs_test WHERE word LIKE 'f%'; 
+---------+ 
| word | 
+---------+ 
| froogle | 
| flickr | 
+---------+ 
2 rows in set (0.00 sec) 

########### 
# end 
########### 


3、還有一種方法就是在查詢時指定collation 

mysql> create table case_test (word VARCHAR(10)) CHARACTER SET latin1; 
Query OK, 0 rows affected (0.01 sec) 

mysql> INSERT INTO case_test VALUES ('Frank'),('Google'),('froogle'),('flickr'),('FlicKr'); 
Query OK, 7 rows affected (0.01 sec) 
Records: 7 Duplicates: 0 Warnings: 0 
mysql> SELECT * FROM case_test WHERE word LIKE 'f%'; 
+---------+ 
| word | 
+---------+ 
| Frank | 
| froogle | 
| flickr | 
| FlicKr | 
+---------+ 
6 rows in set (0.01 sec) 

mysql> SELECT * FROM case_test WHERE word LIKE 'F%'; 
+---------+ 
| word | 
+---------+ 
| Frank | 
| froogle | 
| flickr | 
| FlicKr | 
+---------+ 
6 rows in set (0.01 sec) 


mysql> SELECT * FROM case_test WHERE word COLLATE latin1_bin LIKE 'F%'; 
+---------+ 
| word | 
+---------+ 
| Frank | 
| FlicKr | 
+---------+ 
4 rows in set (0.05 sec) 

mysql> SELECT * FROM case_test WHERE word COLLATE latin1_bin LIKE 'f%'; 
+---------+ 
| word | 
+---------+ 
| froogle | 
| flickr | 
+---------+ 
2 rows in set (0.00 sec) 



mysql> SELECT * FROM case_test WHERE word LIKE 'f%' COLLATE latin1_bin; 
+---------+ 
| word | 
+---------+ 
| froogle | 
| flickr | 
+---------+ 
2 rows in set (0.00 sec) 

mysql> SELECT * FROM case_test WHERE word LIKE 'F%' COLLATE latin1_bin; 
+---------+ 
| word | 
+---------+ 
| Frank | 
| FlicKr | 
+---------+ 
4 rows in set (0.01 sec) 


mysql> SELECT * FROM case_test WHERE word LIKE 'F%' COLLATE latin1_general_cs; 
+---------+ 
| word | 
+---------+ 
| Frank | 
| FlicKr | 
+---------+ 
4 rows in set (0.04 sec)
