我有一个包含地址,状态和邮政编码的地址列。我想将地址,郊区,州和邮政编码提取到单独的列中,如何做到这一点作为地址的长度是可变的,有一个^来分隔地址和“其他”细节。状态长度可以是2或3个字符,邮政编码总是4个字符。
PostalAddress TO BE Address Suburb State Postcode
28 Smith Avenue^MOOROOLBARK VIC 3138^ 28 Smith Avenue MOOROOLBARK VIC 3138
16 Farr Street^HEYFIELD VIC 3858^ 16 Farr Street HEYFIELD VIC 3858
17 Terry Road^LOWER PLENTY VIC 3093^ 17 Terry Road LOWER PLENTY VIC 3093

SQL中的字符串解析很混乱,而且往往很脆弱。我通常认为最好在SQL之外完成这些任务。也就是说,鉴于上面的迷你规范,可以将数据解析为您想要的字段:
select
left(PostalAddress, charindex('^', PostalAddress) - 1) as street_address,
left(second_part, len(second_part) - charindex(' ', reverse(second_part))) as suburb,
right(second_part, charindex(' ', reverse(second_part))) as state,
reverse(substring(reverse(PostalAddress), 2, 4)) as postal_code
from (
select
PostalAddress,
rtrim(reverse(substring(reverse(PostalAddress), 6, len(PostalAddress) - charindex('^', PostalAddress) - 5))) as second_part
from Addresses
) as t1
请注意,您需要将您的表名替换为我在上面的子查询中称为地址的内容。

在我的情况下,只是将字符串中的五位数作为邮政编码:
以下是我的代码:
Select SUBSTRING([Column or string],patindex('%[0-9][0-9][0-9][0-9][0-9]%',[Column or string]),5) AS 'Postcode'
