一、场景
项目使用ShardingJDBC操作数据库
修改SQL执行报错
二、报错信息
### Error updating database. Cause: com.mysql.cj.jdbc.exceptions.MysqlDataTruncation: Data truncation: Out of range value for column 'MSGID' at row 1### The error may involve com.xxx.mapper.service.KeyWordMapper.updateByExample-Inline### The error occurred while setting parameters### SQL: UPDATE t_wx_keyword SET keyword = ?,msgType = ?,msgId = ?,content = ?,createTime = ?,eable = ?,matchType = ?,originId = ?,vdnId = ?

三、原因
表字段的数据类型与实体类属性的类型不一致
在本例中:表字段MSGID的数据类型是int
,而实体类的msgId属性类型是String
,类型不一致
四、解决
方法1、更改表字段数据类型,与实体类属性类型一致
方法2、更改实体类属性类型,与表字段数据类型一致
