在两列中标识类似的字符串值

Question

例如，我的下表包含两列Address1和refAddr。

表格中的一些样本数据如下所示。

我想比较两列匹配。显然在这张表中5235 JFK BLVD＆amp; 5235 John F Kennedy是一对，424 N 2ND ST＆amp; 424 NORTH SECOND是一对。

无论如何在SQL或SSIS中我可以用来摆脱非配对结果并保留配对吗？

Answer 1

一个选项是您可以使用GOOGLE API对地址进行地理编码，解析JSON结果以返回更标准化的结果。这可能非常耗时，但您对数据更有信心。

API允许（我相信）每天2,500次点击，但您可以购买更多。

例如，我选择了5232 JFK Blvd并添加了72116的邮政编码以缩小搜索范围。没有邮政编码，它返回了多个地址（NY，NJ，AR等）

https://maps.googleapis.com/maps/api/geocode/json?address=5232%20JFK%20Blvd&72116sensor=false

关键要素可能是：

formatted_address: "5232 J.F.K. Blvd, North Little Rock, AR 72116, USA",
or
long_name: "John F. Kennedy Boulevard",
