1.int或者tinyint等数值型字段的存储范围已经是固定的,和类型相关2.后面的数字只与显示有关,并且是在开启了zerofill前导零填充的前提下 3.显示的时候,在前面用0补全了 create table my_test( id int unsigned, nums int(2) zerofill, age int(2) ); insert into my_test value(1,1,1); select * from my_test;
给定一串数字,从中删除前导零. public class Test { public static void main(String[] args) { String str = "00000123569"; System.out.println(removeZero(str)); // 123569 str = "000012356090"; System.out.println(removeZero(str)); // 12356090 } public sta
