MySQL保留字

MySQL中的保留字和Java中的保留字一样，在命名时不能使用保留字，所以对于MySQL中的保留字要有个大概的印象，下文自https://dev.mysql.com/doc/refman/5.7/en/keywords.html#获取，如有需要可以到官网查看详情。

以下列表显示了My SQL 5.7中的关键字和保留单词，以及不同版本对单个单词的更改。保留关键字用（R）标记。此外，保留FILENAME。

在某些时候，您可能会升级到更高的版本，因此，查看未来的保留字也是一个好主意。您可以在包含更高版本My SQL的手册中找到这些。标准SQL禁止列表中的大多数保留字作为列或表名（例如，GROUP）。保留了一些，因为我的SQL需要它们并使用yacc解析器。
