Question

在查询中（MainQuery，对于示例而言并不复杂），我需要在不同字段上使用计数器，这些计数器有一种方法出现在单独的数据集中而不是所有行中吗？谢谢你的帮助。

WITH 
MainQuery  AS(
SELECT   ROW_NUMBER() OVER (ORDER BY tb17.[NO]) AS OrderId,
* FROM [OFFRES] tb17),

Counters as (SELECT *,
(select MAX(OrderId) FROM MainQuery ) AS 'TotalRecs',
sum(case when [TypeLoc]=215 then 1 else 0 end) over() Loc215,
sum(case when [TypeLoc]=220 then 1 else 0 end) over() Loc220,
sum(case when [TypeLoc]=526 then 1 else 0 end) over() Loc526,
sum(case when [TypeLoc]=209 then 1 else 0 end) over() Loc209,
sum(case when [TypeLoc]=223 then 1 else 0 end) over() Loc223 
/*...*/
from MainQuery
)

SELECT * FROM Counters  WHERE OrderId BETWEEN 1 AND 20000

一个数据集中的实际输出：

OrderId No  TypeLoc TotalRecs   Loc215  Loc220  Loc526  Loc209  Loc223
1       399 218     28097       1299    1349    1324    1346    1329
2       403 223     28097       1299    1349    1324    1346    1329
3       404 223     28097       1299    1349    1324    1346    1329
4       405 223     28097       1299    1349    1324    1346    1329
5       406 223     28097       1299    1349    1324    1346    1329

我想要的输出：

首先 - 所有结果行：

OrderId No  TypeLoc 
1       399 218
2       403 223
3       404 223
4       405 223
5       406 223

秒 - 连续的所有统计数据：

TotalRecs   Loc215  Loc220  Loc526  Loc209  Loc223
28097       1299    1349    1324    1346    1329

在不知道您的表结构的情况下，我会说在两个单独的select语句中执行此操作并仅选择适当的列

WITH 
MainQuery  AS(
SELECT   ROW_NUMBER() OVER (ORDER BY tb17.[NO]) AS OrderId,
* FROM [OFFRES] tb17)

SELECT OrderId, No, TypeLoc
FROM MainQuery
WHERE OrderId BETWEEN 1 AND 20000

和

WITH 
MainQuery  AS(
SELECT   ROW_NUMBER() OVER (ORDER BY tb17.[NO]) AS OrderId,
* FROM [OFFRES] tb17),

Counters as (SELECT 
(select MAX(OrderId) FROM MainQuery ) AS 'TotalRecs',
sum(case when [TypeLoc]=215 then 1 else 0 end) over() Loc215,
sum(case when [TypeLoc]=220 then 1 else 0 end) over() Loc220,
sum(case when [TypeLoc]=526 then 1 else 0 end) over() Loc526,
sum(case when [TypeLoc]=209 then 1 else 0 end) over() Loc209,
sum(case when [TypeLoc]=223 then 1 else 0 end) over() Loc223 
/*...*/
from MainQuery
)
SELECT TotalRecs, Loc215, Loc220, Loc526, Loc209, Loc223
FROM Counters
WHERE OrderId BETWEEN 1 AND 20000

统计数据的SQL独立数据集 - DataTable的集合
