SQL插入#TEMP表

Question

CREATE TABLE #TEMP (Date NVARCHAR(256),Pending NVARCHAR(256),Complete NVARCHAR(256) ,Total NVARCHAR(256)); 
INSERT INTO #TEMP (Date,Pending,Total) 
SELECT DISTINCT(DATEE),'','' from E_R_MainT 
GROUP BY DATEE 

UPDATE #TEMP 
SET Pending=(SELECT COUNT(R_ID) FROM E_R_MainT WHERE STATUS !='S_2' GROUP BY (CONVERT(char(10), HOD_DT ,126))) 
WHERE #TEMP.Date = (SELECT DISTINCT(DATEE) from E_R_MainT 
GROUP BY DATEE) 

UPDATE #TEMP 
SET Complete=(SELECT COUNT(R_ID) FROM E_R_MainT WHERE STATUS !='S_1' GROUP BY DATEE) 
WHERE #TEMP.Date = (SELECT DISTINCT(DATEE) from E_R_MainT 
GROUP BY DATEE) 

UPDATE #TEMP 
SET Total=(SELECT COUNT(R_ID) FROM E_R_MainT GROUP BY (DATEE)) 
WHERE #TEMP.Date = (SELECT DISTINCT(DATEE) from E_R_MainT 
GROUP BY DATEE 
SELECT * FROM #TEMP 

當執行我查詢我得到這個錯誤：

「子查詢返回的多個值，這是不允許」

是我的表源：

我期待這樣的輸出：

Answer 1

一些容易混淆的命名會在這裏等，我懷疑實際上，您的查詢部分中出現的幾個不同名稱意在命名相同的列。

不應該有必要在這裏臨時表 - 只要使用合適的集合體：

SELECT 
    DATEE, 
    SUM(CASE WHEN Status = 's_1' THEN 1 ELSE 0 END) as Pending, 
    SUM(CASE WHEN Status = 's_2' THEN 1 ELSE 0 END) as Complete, 
    COUNT(*) 
FROM E_R_MainT 
GROUP BY DATEE 

Answer 2

這部分導致問題出現的你..

WHERE #TEMP.Date = (SELECT DISTINCT(DATEE) from E_R_MainT 
GROUP BY DATEE) 

變化to..below，沒有必要的獨特和group by

WHERE #TEMP.Date in (SELECT (DATEE) from E_R_MainT 

Answer 3

此示例代碼從您：

UPDATE #TEMP 
SET Total=(SELECT COUNT(R_ID) FROM E_R_MainT GROUP BY (DATEE)) 
WHERE #TEMP.Date = (SELECT DISTINCT(DATEE) from E_R_MainT 
GROUP BY DATEE 
SELECT * FROM #TEMP 

這

SELECT COUNT(R_ID) FROM E_R_MainT GROUP BY (DATEE)) 
WHERE #TEMP.Date = (SELECT DISTINCT(DATEE) from E_R_MainT 
GROUP BY DATEE 

內容

不是隻返回一個，我認爲它返回多個值，檢查所有查詢上面的那個外觀 像那樣。我確定這是給你錯誤的原因。
