SQL查询数据库中数据统计信息

项目背景

业务系统上线经常面临历史数据与系统同步问题，我们项目中的做法是

1. 新发生的项目严格走系统；

2.历史项目逐年倒推，导入系统；

因为工程项目的周期一般要超过1年，在导入2018年项目时，就会面临项目数据分布在17年、18年，甚至16年，需要对比系统中数据与财务数据、部门统计数据的差异，调整数据一致后再统一导入系统中，完成线下到线上的切换；

需求描述

需要导出系统中所有工程项目的基本信息、相关采购订单、相关合同额/送审额/审定额、开票次数、开票金额、单项拆分金额（一次开票涉及多个单项）、回款次数、回款金额

最终结果

Excel中进行对比的公式

=VLOOKUP(B2,部门提供数据!A:K,5,0)-F2

查找 部门提供数据!A:K 中与B2值相同的行，取该行第5列的数字，减去F2的值

示例：系统导出的单项合同额与部门提供的合同额偏差；

 

快速复制公式到列

在左上角名字处输入：Q2:Q5149 这样选中多个列；

然后 shift 输入公式 =VLOOKUP(B2,部门提供数据!A:K,6,0)-G2 

然后 Ctrl+回车
