今天项目组的一个同事问我如何快速的找到一个Excel中第3列和第5列的值完全重复的值,我想了想虽然Excel中自带查找重复值的功能,但是好像只能对同一列进行比较,所以就写了一个VBA进行处理,VBA非常简单,但效果不错. Sub FindDuplicatesInColumn() Dim lastRow As Long Dim matchFoundIndex As Long Dim iCntr As Long lastRow = ' 初始化临时列, 第7列用来存放结果,第8列将3 5两列的值拼接起
#include <iostream> #include <cmath> using namespace std; const int n = 10000; int isPrime(int n); int main() { for(int i = 2; i < n;++ i) {//产生10000个数队列 if(isPrime(i)) { //判断变换前的数是否为素数 int count = 1; int sum = 0; for(int j = i;j > 1;) {
select * from (select count(name) as isone, name from tbl_org_departments group by name) t where t.isone > 1; 解释: 子句查出下列结果集作为主句的表, 当isone列为1时说明没有重复, 大于1时说明存在重复 执行子句时结果:
