mysql字符集編碼錯誤的導(dǎo)入數(shù)據(jù)會提示錯誤了，這個和插入數(shù)據(jù)一樣如果保存的數(shù)據(jù)與mysql編碼不一樣那么肯定會出現(xiàn)導(dǎo)入亂碼或插入數(shù)據(jù)丟失的問題，下面我們一起來看一個例子。

恢復(fù)數(shù)據(jù)庫報錯：由于字符集問題，最原始的數(shù)據(jù)庫默認(rèn)編碼是latin1，新備份的數(shù)據(jù)庫的編碼是utf8，因此導(dǎo)致恢復(fù)錯誤。

其他的一些設(shè)置方法：
修改數(shù)據(jù)庫的字符集
mysql>use mydb mysql>alter database mydb character set utf-8;
創(chuàng)建數(shù)據(jù)庫指定數(shù)據(jù)庫的字符集
mysql>create database mydb character set utf-8;
通過配置文件修改:
修改/var/lib/mysql/mydb/db.opt
default-character-set=latin1 default-collation=latin1_swedish_ci
為
default-character-set=utf8 default-collation=utf8_general_ci
重起MySQL:
[root@bogon ~]# /etc/rc.d/init.d/mysql restart
通過MySQL命令行修改:
mysql> set character_set_client=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_connection=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_database=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_results=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_server=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_system=utf8; Query OK, 0 rows affected (0.01 sec) mysql> set collation_connection=utf8; Query OK, 0 rows affected (0.01 sec) mysql> set collation_database=utf8; Query OK, 0 rows affected (0.01 sec) mysql> set collation_server=utf8; Query OK, 0 rows affected (0.01 sec)
