Question

我有一个包含一列地址的表。要在报告中使用，我需要按位置对数据进行排序，即N，NW，S，SE，W和称为State的分隔符。这些并不总是在该领域的最后。

SELECT 
  Event.EventID, 
  Event.EventDateTime, 
  SUBSTRING(RIGHT(RTRIM(Event.Location),2), 1, 2) AS Loc, 
  Event.Location 
FROM Event AS Event 
WHERE Event.EventDateTime BETWEEN '12/11/2014' AND '12/12/2014' 
AND Event.Location LIKE '% NW %' 
ORDER BY Event.EventDateTime

这会给我

ALTIMONT DR NW＆amp; CASCADE DR NW

但我也需要

5765商业街道STE 170，地铁三明治

Answer 1

根据您当前的条件，您只需OR。

WHERE Event.EventDateTime BETWEEN '12/11/2014' AND '12/12/2014' 
AND (Event.Location LIKE '% NW %' 
  OR Event.Location LIKE '% SE %'  
  OR Event.Location LIKE '% S %' 
  OR Event.Location LIKE '% W %')
ORDER BY Event.EventDateTime

注意括号将OR子句分组为一个。

此外，一个简单的案例陈述可以为您提供方向，无论位置如何：

SELECT 
  Event.EventID, 
  Event.EventDateTime, 
  case when CHARINDEX (' NW ', event.location) > 0 
       then SUBSTRING(Event.Location, CHARINDEX (' NW ', event.location) + 1, 2) 
       when CHARINDEX (' SE ', event.location) > 0 
       then SUBSTRING(Event.Location, CHARINDEX (' SE ', event.location) + 1, 2)
       when CHARINDEX (' S ', event.location) > 0 
       then SUBSTRING(Event.Location, CHARINDEX (' S ', event.location) + 1, 1)
       when CHARINDEX (' W ', event.location) > 0 
       then SUBSTRING(Event.Location, CHARINDEX (' W ', event.location) + 1, 1)
  end AS Loc, 
  Event.Location 
FROM Event AS Event WHERE Event.EventDateTime BETWEEN '12/11/2014' AND '12/12/2014' 
AND (Event.Location LIKE '% NW %' 
  OR Event.Location LIKE '% SE %'  
  OR Event.Location LIKE '% S %' 
  OR Event.Location LIKE '% W %')
ORDER BY Event.EventDateTime

SQL Server没有本机正则表达式分组，或者这可以简化。

根据字符串的一部分对行进行排序
