SQL Server计数使用偏移量来区分

Question

使用此查询：

SELECT ID,Make,Model 
FROM cars 
WHERE active='true'  
ORDER BY make ASC, model ASC 
OFFSET 0 ROWS FETCH NEXT 5 ROWS ONLY;

我得到了这个结果：

ID          Make         Model
26800911    AIXAM       CROSSLINE
26796643    AIXAM       PREMIUM
26700448    ALFA ROMEO  145
26796420    ALFA ROMEO  147
26480721    ALFA ROMEO  147

如何编写查询从该结果中获取每个make的计数？ 所以我需要AIXAm = 2，Alfa Romeo = 3

选择一个返回所有结果而没有偏移限制

SELECT make,SUM(CASE WHEN active='true' THEN 1 ELSE 0 END) 
FROM cars 
WHERE active='true' 
GROUP BY make 
ORDER BY make ASC;

和

SELECT make,Count(make) 
FROM cars 
WHERE active='true' 
GROUP BY make 
ORDER BY make ASC;

和

SELECT TOP 5 make,SUM(CASE WHEN active='true' THEN 1 ELSE 0 END) 
FROM cars 
WHERE active='true' 
GROUP BY make 
ORDER BY make ASC;

全部归还不是我需要的

AIXAM       2
ALFA ROMEO  106
ALPINA      1
AUDI        686
BMW         557

Answer 1

您可以尝试使用子查询：

SELECT q.Make, Count(q.ID)
FROM
(
SELECT ID,Make,Model 
FROM cars 
WHERE active='true'  
ORDER BY make ASC, model ASC 
OFFSET 0 ROWS FETCH NEXT 5 ROWS ONLY
) AS q
GROUP BY q.make
ORDER BY q.make ASC;
