mysql的boolean设置

MySQL没有boolean类型。这也是比较奇怪的现象。例：

create table xs

(

id int primary key,

bl boolean

)

这样是可以创建成功，但查看一下建表后的语句，就会发现，mysql把它替换成

tinyint(1)。也就是说mysql把boolean=tinyInt了。

boolean类型

MYSQL保存BOOLEAN值时用1代表TRUE,0代表FALSE，boolean在MySQL里的类型为tinyint(1),

MySQL里有四个常量：true,false,TRUE,FALSE,它们分别代表1,0,1,0
