Linux上安装MySQL默认是数据库的表大小写敏感的。修改很简单,只要该一个mysql的配置文件就可以了。

84 rows in set (0.00 sec)

mysql> select count(*) from TREND;
ERROR 1146 (42S02): Table ‘cddl.TREND‘ doesn‘t exist

从上面可以看出trend表是存在的,只不过是小写的保存在数据库里。

 

 

让MYSQL不区分表名大小写的方法其实很简单:

1.用ROOT登录,修改/etc/my.cnf

2.在[mysqld]下加入一行:lower_case_table_names=1

3.重新启动数据库即可

 

[root@chicago init.d]# vi /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables
lower_case_table_names=1

 

[root@chicago init.d]# service mysql restart
Shutting down MySQL..                                      [  OK  ]
Starting MySQL......................................       [  OK  ]

 

mysql> select count(*) from TREND;
+----------+
| count(*) |
+----------+
|       19 |
+----------+
1 row in set (0.00 sec)

mysql> select count(*) from trend;
+----------+
| count(*) |
+----------+
|       19 |
+----------+
1 row in set (0.00 sec)

从上面可以看出,此时已经不区分大小写了。
