在查询中（MainQuery，示例并不复杂），我需要不同字段上的计数器，有一种方法可以让这些计数器出现在单独的数据集中而不是在所有行中？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

第二 - 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选择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
