Question

基本上我试图获取一列的地址字段并将其分成三列，第一列具有地址编号，第二列具有街道名称，第三列具有地址＃或者很多＃

Address
-------------------
990 A street Apt 1B
127 B street Lot 3

到目前为止，我有这个适用于号码和街道。

Select LEFT(MP.[ADDRESS],PATINDEX('%[0-9][^0-9]%', MP.[ADDRESS] )) AS Number,
       LTRIM(RIGHT(MP.[ADDRESS], LEN(MP.[ADDRESS]) - PATINDEX('%[0-9][^0-9]%', MP.[ADDRESS] ))) As Street 
From MPFILE mp

它最终会像这样：

Number  |   Street
----------------------------
990     |    A street Apt 1B
127     |    B Street Lot 3

试图解决这个问题：

Number   |   Street    |  Apt/Lot
-----------------------------------
990      |   A street  |  Apt 1B
127      |   B street  |  Lot 3

Answer 1

这样的东西可以用你给出的示例数据，但正如Gordon所说，地址很难解析，可能不应该用SQL解析。

WITH locations AS
(
  SELECT ADDRESS, 
          LEN(ADDRESS) AS Len,
          PATINDEX('%[0-9][^0-9]%', ADDRESS) AS NumLoc,
          PATINDEX('%APT%', ADDRESS) AS APTLoc,
          PATINDEX('%Lot%', ADDRESS) AS LotLoc
  FROM MPFILE
), numbers AS
(
   ADDRESS,
   NumLoc,
   Len - NumLoc AS StartAddr,
   CASE WHEN APTLoc > 0 THEN AptLoc
        WHEN LotLoc > 0 THEN LotLoc
        ELSE Len AS EndAddr,
   CASE WHEN APTLoc > 0 THEN AptLoc
        WHEN LotLoc > 0 THEN LotLoc
        ELSE Len AS StartApt,
   Len AS EndApt
)
Select LEFT(NumLoc, MP.ADDRESS )) AS Number,
       SUBSTRING(MP.ADDRESS, StartAddr, EndAddr), 
       SUBSTRING(MP.ADDRESS, StartApt, EndApt)
From numbers

Answer 2

Declare @t table  ( Address varchar(200));

Insert Into @t (Address) values
    ('990 A street Apt 1B'),
    ('127 B street Lot 3'),
    ('127 B street Lot 345'),
    ('4444 Rice Street Suite 105'),
    ('715 South King Street #200'),
    ('101 Aupuni Street Room 342')

Select  Left(Address,CHARINDEX(' ',Address)) as Number,
        SUBSTRING(Address,CHARINDEX(' ',Address)+1, CHARINDEX('street',SUBSTRING(Address,CHARINDEX(' ',Address)+1,LEN(Address)))+LEN('street')) as Street
        ,Substring(Address,CHARINDEX('street',Address)+LEN('street'),LEN(Address)) as [Apt/Lot]
From    @t

**结果**

Number  |Street             |Apt/Lot
----------------------------|-------
990     |A street           |Apt 1B
127     |B street           |Lot 3
127     |B street           |Lot 345
4444    |Rice Street        |Suite 105
715     |South King Street  |#200
101     |Aupuni Street      |Room 342

SQL将一列分为三列
