Question

在MS Access 2013中工作。拥有大量需要标准化的位置/地址。

示例包括以下地址：

500 W Main St
500 West Main St
500 West Main Street

你明白了。

我已经考虑过运行一个查询来提取数据库中左（7）或者某些字符不止一次存在的所有记录，但该逻辑中存在明显的缺陷。

是否有一个函数或查询或其他任何可以帮助我生成一个地址可能存在多次的记录列表，以略有不同的方式生成？

Answer 1

这是一项棘手的事业......等同于黑魔法和科学。你会惊讶于大道的变化。

这就是我使用Google API的原因。对于初始数据集，这可能是耗时的，但是只需要解决新的添加。

例如

https://maps.googleapis.com/maps/api/geocode/json?address=500 S Main St,Providence RI 02903

返回部分

"formatted_address" : "500 S Main St, Providence, RI 02903, USA"

和好消息是

https://maps.googleapis.com/maps/api/geocode/json?address=500 South Main Steet,Providence RI 02903

返回与上一个查询相同的格式化地址

"formatted_address" : "500 S Main St, Providence, RI 02903, USA"

VBA示例：

执行以下代码......

' VBA project Reference required:
' Microsoft XML, v3.0

Dim httpReq As New MSXML2.ServerXMLHTTP
httpReq.Open "GET", "https://maps.googleapis.com/maps/api/geocode/json?address=500 South Main Steet,Providence RI 02903", False
httpReq.send
Dim response As String
response = httpReq.responseText

...字符串变量response包含以下JSON数据：

         "address_components" : [
