SQL Server加入兩個查詢

Question

我有一個表（t），我需要從中獲取一些信息。 我正在使用這2個查詢來獲取它。
但是有沒有辦法讓它在單個查詢？

SELECT nrplu, SUM(preco) as TP, SUM(kg) as TK, seccao 
FROM t 
GROUP BY nrplu, seccao 


SELECT nrplu, count(*) as TT FROM t GROUP BY nrplu 

Answer 1

這應該適合你。

WITH CTE_preselect AS 
(SELECT nrplu, count(*) as TT 
FROM t 
GROUP BY nrplu) 

SELECT t.nrplu,TT, SUM(preco) as TP, SUM(kg) as TK, seccao 
FROM t 
    JOIN CTE_preselect ON t.nrplu = CTE_preselect.nrplu 
GROUP BY t.nrplu,TT, seccao
