【小bug日记】MySQL 关键字和保留字汇总 Failed to complete request: org.springframework.jdbc.BadSqlGrammarException
springboot + mybatis-plus
报错：Failed to complete request: org.springframework.jdbc.BadSqlGrammarException
报错：Cause: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order
原因：数据库中我们设置的字段名称和数据库中的关键字名称重名
一开始认为 图中status字段重名，改为order_status后依然报错
事实上是表名order重名
解决方法：
解决方法
1.实体类中指定表名，加上反引号即可使用mysql关键字
2.更改表名
