Question

当前，我的查询选择了我的WHERE子句中指定的所有位置，并返回了所有包含提供邮政编码的位置的邮政编码。我的目标是返回所有带有未提供送货地区的邮政编码的位置。数据库中有成千上万个邮政编码，所以不是NOT的选择，因为我需要将结果限制在这些邮政编码中。我觉得这很容易实现，但是解决方案使我逃脱了。

SELECT ORS.PostDate
,ORS.Name
,ORS.Address
,ORS.City
,ORS.State
,ORS.Zip
,ORS.DriverID
,W.FirstName
,W.LastName
,ORS.RouteID


FROM tblOrderRouteStops ORS WITH (NOLOCK)
INNER JOIN tblWorker W WITH (NOLOCK) ON W.WorkerID = ORS.DriverID

--Select all distinct zips from tblOrderRouteStops, then use where clause to filter them to specified locations.
FULL OUTER JOIN 
(SELECT DISTINCT ORSS.Zip FROM
tblOrderRouteStops ORSS WITH (NOLOCK)) as B
ON B.Zip = ORS.Zip

WHERE ORS.PostDate >= dateadd(day,datediff(day,1,GETDATE()),0)
AND ORS.PostDate < dateadd(day,datediff(day,0,GETDATE()),0)
AND ORS.CustID = 104105
AND ORS.StopType = 1
AND (ORS.Zip = 16635
OR ORS.Zip = 25504
OR ORS.Zip = 28401
OR ORS.Zip = 28803
OR ORS.Zip = 30901
OR ORS.Zip = 31904
OR ORS.Zip = 35801
OR ORS.Zip = 37921
OR ORS.Zip = 38801
OR ORS.Zip = 39232
OR ORS.Zip = 46825
OR ORS.Zip = 49428
OR ORS.Zip = 50265
OR ORS.Zip = 54915
OR ORS.Zip = 67214
OR ORS.Zip = 72205
OR ORS.Zip = 72764
OR ORS.Zip = 72916
OR ORS.Zip = 79605)

Answer 1

使用NOT IN运算符，如

AND ORS.Zip NOT IN (16635,25504,....)

Answer 2

这是一个快速的过程。我接受了原始查询并对其进行了修改，并使用“ before and after”变体，该变体基于最后使用AND子句的情况。

首先，设置一个包含“目标”邮政编码的临时表。使用起来会更容易，SQL会产生更好的执行计划。

DECLARE @TargetZips table
    (
    Zip  char(5)  not null  --  Replace with the datatype you are using
    )

INSERT @TargetZips values
    (16635)
    ,(25504)
    ,(28401)
    ,(28803)
    ,(30901)
    ,(31904)
    ,(35801)
    ,(37921)
    ,(38801)
    ,(39232)
    ,(46825)
    ,(49428)
    ,(50265)
    ,(54915)
    ,(67214)
    ,(72205)
    ,(72764)
    ,(72916)
    ,(79605)

然后查询：

SELECT
 ORS.PostDate
,ORS.Name
,ORS.Address
,ORS.City
,ORS.State
,ORS.Zip
,ORS.DriverID
,W.FirstName
,W.LastName
,ORS.RouteID


FROM tblOrderRouteStops ORS
 INNER JOIN tblWorker W
  ON W.WorkerID = ORS.DriverID

--Select all distinct zips from tblOrderRouteStops, then use where clause to filter them to specified locations.
 FULL OUTER JOIN (--  Restrict this to the set of zip codes you are intersted in
                  SELECT DISTINCT ORSS.Zip
                   FROM tblOrderRouteStops ORSS
                    INNER JOIN @TargetZips tz
                     on tz.Zip = ORSS.zip
                 ) as B
  ON B.Zip = ORS.Zip

WHERE ORS.PostDate >= dateadd(day,datediff(day,1,GETDATE()),0)
AND ORS.PostDate < dateadd(day,datediff(day,0,GETDATE()),0)
AND ORS.CustID = 104105
AND ORS.StopType = 1

将其包含在原始查询中

AND B.Zip is not null

在修改后的查询中添加

AND B.Zip is null

理想情况下，您有两个单独的查询。这样，您就可以避免使用FULL OUTER JOIN了-我建议这样做，它们总是会让我感到紧张。

以下内容，恕我直言，虽然很笨拙，但可以避免使用INSERT：

WITH cteTargetZip 
 as (--  Build a table set based entirely on a values clause
     select Zip
      from (values  (16635)
                   ,(25504)
                   ,(28401)
                   ,(28803)
                   ,(30901)
                   ,(31904)
                   ,(35801)
                   ,(37921)
                   ,(38801)
                   ,(39232)
                   ,(46825)
                   ,(49428)
                   ,(50265)
                   ,(54915)
                   ,(67214)
                   ,(72205)
                   ,(72764)
                   ,(72916)
                   ,(79605)
          ) as TargetZips (Zip)
    )
SELECT...

，然后在主查询中将@TargetZips替换为cteTargetZips。

好吧，这有望完成必要的工作...
