基于ssm的进销存业务实现---数据库
作者:互联网
一、其实当我们在选择使用int的类型的时候,不论是int(3)还是int(11),它在数据库里面存储的都是4个字节的长度,在使用int(3)的时候如果你输入的是10,会默认给你存储位010,也就是说这个3代表的是默认的一个长度,当你不足3位时,会帮你补全,当你超过3位时,就没有任何的影响。 除了在存储的时候稍微有点区别外,在我们使用的时候是没有任何区别的。int(10)也可以代表
2147483647这个 值int(11)也可以代表。要查看出不同效果记得在创建类型的时候加 zerofill这个值
表示用0填充,否则看不出效果的。我 们通常在创建数据库的时候都不会加入这个选项,所以可以
说他们之间是没有区别的。
