sharerecord是mysql关键字吗

Posted 2023-05-15

不是的
在mysql中，下表中的字词显式被保留。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，保留字被引起来后可以用作识别符。
下面是mysql的关键字：

mysql保留关键字的一个小知识

参考技术A 项目中一个表的字段，有三个字段名 desc , type , status 。这三个都是跟mysql的关键字重名，在写语句的时候都会标蓝。

但是有趣的是，执行的时候只有 desc 会报错

这是为什么？
我们查询mysql的关键字和保留字列表就能看到

虽然是允许的，但是我们使用的时候还是要尽量谨慎使用。
