如何在SQL中加入兩個查詢（Oracle）

Question

如何加入這些查詢？

SELECT RCTDT, SUM(RCTAMOUNT), COUNT(RCTAMOUNT) FROM RECEIPTS4 
WHERE RCTDT BETWEEN '01-nov-2009' AND '30-nov-2009' 
AND RCTTYPE='CA' AND RCTAMOUNT>0 
GROUP BY RCTDT 

--- 

SELECT RCTDT, SUM(RCTAMOUNT), COUNT(RCTAMOUNT) FROM RECEIPTS4 
WHERE RCTDT BETWEEN '01-nov-2009' AND '30-nov-2009' 
AND RCTTYPE='CQ' AND RCTAMOUNT>0 
GROUP BY RCTDT 

Answer 1

使用IN操作者：

SELECT RCTDT, SUM(RCTAMOUNT), COUNT(RCTAMOUNT) FROM RECEIPTS4 
WHERE RCTDT BETWEEN '01-nov-2009' AND '30-nov-2009' 
AND RCTTYPE IN ('CA','CQ') AND RCTAMOUNT>0 
GROUP BY RCTDT 

Answer 2

在該特定示例中，使用一個由IN作爲克萊圖斯建議。在其他情況下，如果不能從相同的選擇產生的兩個結果集，使用UNION的結果結合起來：

SELECT something FROM somewhere 
UNION 
SELECT something FROM somewhere_else 

Answer 3

也許你的意思是這個

SELECT RCTDT, 
SUM(case when rcttype='CA' then RCTAMOUNT else null end) as CASUM, 
COUNT(case when rcttype='CA' then RCTAMOUNT else null end) as CACOUNT, 
SUM(case when rcttype='CQ' then RCTAMOUNT else null end) as CQSUM, 
COUNT(case when rcttype='CQ' then RCTAMOUNT else null end) as CQCOUNT, 
FROM RECEIPTS4 
WHERE RCTDT BETWEEN '01-nov-2009' AND '30-nov-2009' 
AND RCTTYPE in('CA','CQ') AND RCTAMOUNT>0 
GROUP BY RCTDT 

Answer 4

SELECT RCTDT，SUM（RCTAMOUNT） ，COUNT（RCTAMOUNT）FROM RECEIPTS4 WHERE RCTDT BETWEEN '01 -nov-2009' AND '30 -nov-2009' AND RCTTYPE IN（ 'CA'， 'CQ'）AND RCTAMOUNT> 0 GROUP BY RCTDT

也可能有用。
