Mysql学习笔记2(mysql关键字)

beyondfly

在MySQL中，下表中的字显式被保留。其中大多数字进制被标准SQL用作列名和/或表名(例如，GROUP)。少数被保留了，因为MySQL需要它们，(目前)使用yacc解析程序。保留字被引起来后可以用作识别符。

上周在学习insert into语句的时候，出现了一个问题一直不明白，后来问了群里的兄弟才知道，原来是使用了add做为列的名字，因此，特把mysql的关键字记在博客上，供后续查阅

请问楼主这些关键字是怎么得到的

MySQL 手册里有，注意找对应版本的，比如较之5.1， 5.5有一些新添加的。
如果现在上线5.1的系统，注意避免5.5,5.6的保留字，以免以后作升级带来的痛苦。

MySQL5.5手册参见8.3节

我来提供个方法检测是否是系统关键字

1. 
   
2. grep INSERT mysql/sql/sql_yacc.yy|grep '%token'
   

复制代码

如果有输出的话就表示是关键字
