#今天遇到一个问题，把某一字段重新命名为condition时报错，于是联想到可能是MySQL的关键字，用``引起来后，问题解决。
#在MySQL数据库中，Table字段不能使用MySQL关键字；
#【如果非要使用这些关键字，则需要在关键前后添加 `keyword` 反引号以示区分】
#MySQL允许部分关键字用做未引起来的识别符，因为许多人以前曾使用过它们。
#像name，type 这种常用的字段，MySQL 做了一些处理 name 不报错 type 报错；
#常用字段跟 MySQL 关键字冲突的解决方法：
#键盘1左边的反引号括起来，即以`name`的形式括；
# mysql关键字有以下这些：
