StarRocks 中的所有保留关键字
本文介绍了什么是非保留关键字和保留关键字，并列举了 StarRocks 中的所有保留关键字。
简介
关键字在 SQL 语句中具有特殊的含义，比如CREATE 和 DROP，其中：
- 非保留关键字 (Non-reserved keywords) 可以直接作为标识符，如表名和列名。例如，DB 是非保留关键字，如要创建一个名为
DB的数据库，语法如下。CREATE DATABASE DB; Query OK, 0 rows affected (0.00 sec) - 保留关键字 (Reserved keywords) 不能直接作为标识符给变量或者函数等命名，需要做特殊处理。在 StarRocks 中，使用保留关键字作为标识符，需要用反引号 (`) 将其括起。例如，LIKE 为保留关键字，如要创建一个名为
LIKE的数据库，语法如下。CREATE DATABASE `LIKE`; Query OK, 0 rows affected (0.01 sec)

I really enjoyed reading your post it was both informative and personal, which I think is the perfect combo. You explained things in a simple way that actually helped me understand better. It didn't feel overwhelming at all. Thanks for taking the time to share your experience. It's posts like these that make a real difference for people who are looking for genuine advice. Keep up the great work! I came across Libya's e-visa option while planning a spontaneous trip. Understanding the Libya tourist visa requirements helped me feel confident before booking. Everything was surprisingly straightforward. Once I arrived, I was amazed by the Roman ruins, local hospitality, and peaceful coastal towns. It felt like stepping into a place that time forgot, in the best way.
