许多服务器系统变量是动态的,可以在运行时进行设置。
参见“变量赋值的SET语法”。
有关设置系统变量的权限要求的描述,请参阅“系统变量权限”
【MySQL精通之路】系统变量-系统变量权限-CSDN博客
下表列出了所有适用于mysqld的动态系统变量。
该表列出了每个变量的数据类型和范围。
最后一列指示每个变量的作用域是Global、Session还是两者都有。
有关设置和使用变量的详细信息,请参阅相应的项目说明。
在适当的情况下,将提供与有关项目的进一步信息的直接链接。
具有“string”类型的变量采用字符串值。
类型为“numeric”的变量采用数值。
具有“boolean”类型的变量可以设置为0、1、ON或OFF。
标记为“枚举”的变量通常应设置为变量的可用值之一,但也可以设置为与所需枚举值对应的数字。对于枚举的系统变量,第一个枚举值对应于0。
这与用于表列的ENUM数据类型不同,后者的第一个枚举值对应于1。
