##指定列求和 需求: 求和:列为“销售金额”的数值 Sub 求和()Dim i As Integer, j As IntegerFor i = 3 To 56For j = 15 To 81 Step 2Cells(i, 13) = Cells(i, 13) + Cells(i, j)Next jNext i End Sub 中间有一段无法调试的代码, Sub 求和()Dim i As Integer, j As IntegerFor i = 3 To range("a65536")
1.判断列内是否有重复值: Dim arrT As Range Dim rng As Range Set arrT = Range("A:A")'判读A列单元格 For Each rng In arrT If rng = Empty Then'如果单元格为空就退出循环,否者循环65535次 Exit For End If k = Application.CountIf(arrT, rng)’用CountIf函数扫描出重复值,跟excel的CountIF函数一样 If k > 1
创建每列随机值的语句 create table TEST_ZHAA01A_03 as select rownum as id, to_char(sysdate + rownum/24/3600, 'yyyy-mm-dd hh24:mi:ss') as inc_datetime, trunc(dbms_random.value(0, 999999999999)) as random_id, dbms_random.string('x', 20) random_string from dual co

Naïve Bayes Classifier. We will use, specifically, the Bernoulli-Dirichlet model for text classification, We will train the model using both the Maximum Likelihood estimates and Bayesian updating, and compare these in terms of predictive success, and
java数据编列并求和,江湖我狼哥,人狠话不多,直接上代码! import java.util.Arrays; public class Intarry { public static void main (String[] args){ //定义一个数组 int intarry[] = {20,30,40,10}; int num=0; Arrays.sort(intarry); //正序 for(int J =0;J < intarry.length;J++){ System.out.pri
使用IDENTITY列属性 1. 建立表 Sales.MyOrders USE TSQL2012; IF OBJECT_ID(N'Sales.MyOrders', N'U') IS NOT NULL DROP TABLE Sales.MyOrders; GO CREATE TABLE Sales.MyOrders ( orderid , 1) CONSTRAINT PK_MyOrders_orderid PRIMARY KEY, custid INT NOT NULL ), empid INT
