数据库字符集的坑

Incorrect string value: '\xE5\x95\x8A\xE5\x8F\xAF...' for column 'detect_name' at row 1

首先找到对应表，执行show create table table_name ;

查看表的详细信息

例如：

CREATE TABLE `b_event_detect` (
  `detect_id` int(11) NOT NULL AUTO_INCREMENT,
  `topological_id` int(11) DEFAULT NULL,
  `detect_name` varchar(128) CHARACTER SET latin1 DEFAULT NULL,
  `detect_type` varchar(20) CHARACTER SET latin1 DEFAULT NULL COMMENT '0:default_event;1:app_monitor;2:host_action;3:network_generate;4:network_rule;5:total_rule;11:real_log',
  `port` int(11) DEFAULT NULL,
  `keyword` varchar(1024) CHARACTER SET latin1 DEFAULT NULL,
  `node_id` bigint(20) DEFAULT NULL,
  `interface_id` bigint(20) DEFAULT NULL,
  `states` varchar(50) CHARACTER SET latin1 DEFAULT NULL,
  `trafficsave_flag` varchar(50) CHARACTER SET latin1 DEFAULT NULL,
  `trafficcollection_flag` varchar(50) CHARACTER SET latin1 DEFAULT NULL,
  PRIMARY KEY (`detect_id`)
) ENGINE=MyISAM AUTO_INCREMENT=19198 DEFAULT CHARSET=utf8

查看表的最末尾表的字符集格式和每个字段的字符集格式

如果有问题的改成utf-8

修改数据库字符集：

ALTER DATABASE db_name DEFAULT CHARACTER SET character_name [COLLATE ...]; 把表默认的字符集和所有字符列（CHAR,VARCHAR,TEXT）改为新的字符集：

ALTER TABLE tbl_name CONVERT TO CHARACTER SET character_name [COLLATE ...] 如：ALTER TABLE logtest CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

只是修改表的默认字符集：

ALTER TABLE tbl_name DEFAULT CHARACTER SET character_name [COLLATE...]; 如：ALTER TABLE logtest DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

修改字段的字符集：

ALTER TABLE tbl_name CHANGE c_name c_name CHARACTER SET character_name [COLLATE ...]; 如：ALTER TABLE logtest CHANGE title title VARCHAR(100) CHARACTER SET utf8 COLLATE utf8_general_ci;

查看数据库编码：

SHOW CREATE DATABASE db_name;

查看表编码：

SHOW CREATE TABLE tbl_name;

查看字段编码：

SHOW FULL COLUMNS FROM tbl_name;

查看系统的编码字符

SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';

MySQL字符集设置

完美解决bug
