访问脚本以查找两个表之间的类似匹配 [英] Access Script to Find Similar matches between two tables

问题描述

您好，

我有一个来自外部公司的文件，我将每月收到两次。当文件进来时，我必须将他们的文件与内部文件进行比较并找到匹配项。我知道如何通过连接两个表来找到完全匹配，但我需要确定两个确切的
和类似的匹配。

I have a file from an outside company which I will receive twice a month. When the file comes in I have to compare their file to an internal file and find matches. I know how to find exact matches by joining two tables, but I need to identify both exact and similar matches.

每个文件都有一个策略编号，但是他们的文件可能有中间的空格，添加一个扩展/前缀，以防止完全匹配。如何识别表1中保单编号中至少5个字符与表2中
策略编号匹配的实例？保单号码由字母和数字组成，可能包含句号，连字符甚至斜线。

Each file has a policy number, however their file may have a space in the middle, add an extension/prefix which would prevent an exact match. How can identify instances where a minimum of 5 characters within the policy number from table 1 match the policy number on table 2? The policy numbers will consist of letters and numbers and may have periods, hyphens or even slashes.

推荐答案

1.当你在Access中查询时，使用左功能LEFT（OldTable.Policy，5）= LEFT（Newtable.Policy，5）



2.有很多方法可以清理数据，其中一种方法是在加载前使用SSIS包清理/验证。

1.While You are querying in Access, Use the left funtion LEFT(OldTable.Policy,5)=LEFT(Newtable.Policy,5)

2.There are many ways to cleansing the data, One of the ways is to use the SSIS packages to clean/Validate before load.
