修改mysql的数据编码格式
在mysql中插入数据时出现
mysql> insert into user values ("1","李红","23","吉林长春","2");
ERROR 1366 (HY000): Incorrect string value: ‘\xE6\x9D\x8E\xE7\xBA\xA2‘ for column ‘name‘ at row 1
因为该列中插入的是中文，所以要修改表user的编码格式
用alter table user default character set utf8;修改
用 show create table user;查询
mysql> alter table user default character set utf8;
Query OK, 0 rows affected (0.03 sec)
Records: 0 Duplicates: 0 Warnings: 0
mysql> show create table user;
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| user | CREATE TABLE `user` (
`id` int(11) DEFAULT NULL,
`name` char(16) CHARACTER SET latin1 DEFAULT NULL,
`age` int(11) DEFAULT NULL,
`address` char(32) CHARACTER SET latin1 DEFAULT NULL,
`wage` tinyint(4) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 |
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.01 sec)
发现name列，和address列仍是latin1的编码格式
用下列两行修改两列的编码格式
alter table user change name name char(16) character set utf8; alter table user change address address char(32) character set utf8;
这样就可以了
