識別兩列中的相似字符串值

Question

例如，我有下列兩列，分別爲Address1和refAddr。

表中的一些示例數據如下所示。

我想的比較兩列用於匹配。顯然在這張表中，5235 JFK BLVD & 5235 John F Kennedy是一對，424 N 2ND ST & 424 NORTH SECOND是一對。

無論如何SQL或SSIS我可以用來擺脫非對結果並保留對？

Answer 1

一個選項是您可以使用GOOGLE API對地址進行地理編碼，解析JSON結果以返回更加標準化的結果。這可能會很耗時，但您會對數據更有信心。

該API允許（我相信）每天2500次點擊，但您可以購買更多。

例如，我選擇了5232 JFK Blvd並添加了72116的郵政編碼以縮小搜索範圍。如果沒有郵政編碼它返回了多個地址（NY，NJ，AR，等）

的關鍵要素可以是：

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