上次我们介绍了lookup查找函数的基本用法,具体可回顾从零开始学数据分析系列-Excel基础入门(三)本节课我们介绍Excel中非常常用的组合函index+match,看看它们的具体用法。 一、INDEX函数基本用法 1、从单行/列中提取指定位置的值 例如,在下表中根据已知的行/列数,提取对应的值。
On the Standard bar, clickNew Query. Copy and paste the following example into the query window and clickExecute. Copy USE AdventureWorks2022; GO -- Find an existing index named AK_UnitMeasure_Name -- on the Production.UnitMeasure table and delete it if found. IF EXISTS (SELECT name from...
=IFERROR(INDEX(A:A,MATCH(E2,B:B,0)),"") 这是最为基础的INDEX+MATCH函数用法,上一章讲过了,这里没什么好再解释的。 2),模糊查询 如下图所示,需要根据E列的姓名查找其对应的学号。和上个例子所不同的是,姓名和数据源的姓名是模糊匹配关系。
if ( First > -1 ) myCharArr[First] = 'f'; if ( Last > -1 ) myCharArr[Last] = 'l'; if ( First == Last ) myCharArr[First] = 'b'; // Displays the array of Char as a String. Console.WriteLine( "{0}{1}", Prefix, new String( myCharArr ) ); } else { Console.Wri...
