MySQL 关键字和保留字汇总(MySQL 8.0)
## MySQL 关键字以及保留字 关键字是在SQL中具有重要意义的单词。某些关键字,如 [`SELECT`](https://dev.mysql.com/doc/refman/8.0/en/select.html) [`DELETE`](https://dev.mysql.com/doc/refman/8.0/en/delete.html) [`BIGINT`](https://dev.mysql.com/doc/refman/8.0/en/integer-types.html) 被保留,需要用作标识符,例如表和列名特殊待遇。内置函数的名称也可能如此。允许使用非保留关键字作为标识符而无需引用。 #### A - `ACCESSIBLE` (R) - `ACCOUNT` - `ACTION` - `ACTIVE`;
