我有一个地址栏,其中包含街道地址以及邮政信箱号码。我想将街道地址和邮政编码提取到一个单独的栏目中,我该怎么做?
样本数据
1 ABC CDE PO BOX 650
15 N. MAIN STREET P.O. BOX 009
(ABC)PO BOX 5909
1 TAKEWAY PLAZA
PO BOX 146012 Parkway STREET
期望的输出: -
STREET ADDRESS ADDRESS2
1 ABC CDE P.O. BOX 650
15 N. MAIN STREET P.O. BOX 009
ABC P.O. BOX 5909
1 TAKEWAY PLAZA
Parkway STREET P.O. BOX 146012
答案 0 :(得分:4)
解析地址可能是一个滑坡。也就是说,你好像是在关注邮政信箱,所以这会让它更容易管理,
也就是说,您可以考虑使用GOOGLE API来规范您的地址Address standardization within a database
这将通过标准化和清洁字符串来产生所需的结果。然后解析字符串,然后通过XML和Stuff()重构它。
有许多可用的解析/拆分功能,我确实在下面提供了

Declare @YourTable table (address varchar(250))
Insert Into @YourTable values
('1 ABC CDE PO BOX 650'),
('15 N. MAIN STREET P.O. BOX 009'),
('(ABC)PO BOX 5909'),
('1 TAKEWAY PLAZA'),
('PO BOX 146012 Parkway STREET')
Select A.*
,C.*
From @YourTable A
Cross Apply (
Select CleanString = replace(replace(replace(replace(replace(replace(replace(A.Address,' ',' '),'P. O','P.O'),'P.','P'),'O. ','O'),'O BOX','OBOX'),'BOX ','BOX'),'POBOX',' POBOX')+' '
) B
Outer Apply (
Select Address1 = Stuff((Select ' ' +RetVal
From [dbo].[udf-Str-Parse](B.CleanString,' ')
Where RetVal Not Like 'POBOX%'
For XML Path ('')),1,1,'')
,Address2 = (Select replace(RetVal,'POBOX','P.O. Box ') From [dbo].[udf-Str-Parse](B.CleanString,' ') Where RetVal Like 'POBOX%')
) C

感兴趣的UDF
CREATE FUNCTION [dbo].[udf-Str-Parse] (@String varchar(max),@Delimiter varchar(10))
Returns Table
As
Return (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace((Select replace(@String,@Delimiter,'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as A
Cross Apply x.nodes('x') AS B(i)
);
--Thanks Shnugo for making this XML safe
--Select * from [dbo].[udf-Str-Parse]('Dog,Cat,House,Car',',')
--Select * from [dbo].[udf-Str-Parse]('John Cappelletti was here',' ')
--Select * from [dbo].[udf-Str-Parse]('this,is,<test>,for,< & >',',')
