在預期條件的上下文中指定的非布爾類型表達式，在'，'附近

Question

我已經查看了其他類似的問題，但我在查詢中沒有Where子句，這讓我有點困惑至於如何解決它。

INSERT INTO #tmpCombined 
SELECT A.Region 
    , 'MyLocation' AS 'Location' 
    , c.Id AS 'CompID' 
    , c.Name AS 'CompName' 
    , 'Cash' AS 'Context' 
    , isnull(sum(CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END,0)) AS 'ZeroDays0' 
    , isnull(sum(CASE WHEN T.TranAge >= 1 and CASE WHEN T.TranAge < 8 THEN 1 ELSE 0 END), 0) AS '1to7Days' 
    , isnull(sum(CASE WHEN T.TranAge >= 8 and CASE WHEN T.TranAge < 16 THEN 1 ELSE 0 END), 0) AS '8to15Days' 
    , isnull(sum(CASE WHEN T.TranAge >= 16 and CASE WHEN T.TranAge < 20 THEN 1 ELSE 0 END), 0) AS '16to20Days' 
    , isnull(sum(CASE WHEN T.TranAge >= 20 THEN 1 ELSE 0 END), 0) AS '20DaysPlus' 
    , COUNT(1) AS 'Total' 
    , A.Level as 'Level' 
    , sum(T.USDDifference) AS 'USDRevaluation' 
    from MyLocation.dbo.Company C 
    inner join #tmpCashTBResults T on T.CompanyId = C.Id 
    inner join #tmpCashAccounts A on T.CompanyId = A.CompanyId 
    group by A.Region, C.Id, C.Name, A.Level 

Answer 1

相近的查詢

1. 修復使用單引號的別名已被棄用。習慣於使用方括號，或者在別名正常時留下它們
2. 當您已經使用SUM(CASE.. WHEN.. THEN 1 ELSE 0 END)時，CASE語句的性質是它永遠不是NULL，所以用ISNULL包裝是多餘的。
3. CASE的基本結構是CASE WHEN <condition> THEN <value>。這裏的<condition>可以是任何表達式，甚至可以是多個比較。

修正並重新格式化查詢：

INSERT INTO #tmpCombined 
    SELECT A.Region 
     , 'MyLocation' AS Location 
     , c.Id AS CompID 
     , c.Name AS CompName 
     , 'Cash' AS Context 
     , sum(CASE WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1 ELSE 0 END) AS ZeroDays0 
     , sum(CASE WHEN T.TranAge >= 1 and T.TranAge < 8 THEN 1 ELSE 0 END) AS [1to7Days] 
     , sum(CASE WHEN T.TranAge >= 8 and T.TranAge < 16 THEN 1 ELSE 0 END) AS [8to15Days] 
     , sum(CASE WHEN T.TranAge >= 16 and T.TranAge < 20 THEN 1 ELSE 0 END) AS [16to20Days] 
     , sum(CASE WHEN T.TranAge >= 20 THEN 1 ELSE 0 END) AS [20DaysPlus] 
     , COUNT(1) AS Total 
     , A.Level as Level 
     , sum(T.USDDifference) AS USDRevaluation 
    from MyLocation.dbo.Company C 
    join #tmpCashTBResults T on T.CompanyId = C.Id 
    join #tmpCashAccounts A on T.CompanyId = A.CompanyId 
group by A.Region, C.Id, C.Name, A.Level; 

Answer 2

該位的位置：

THEN 1 ELSE 0 END,0)) AS 'ZeroDays0' 

應該

THEN 1 ELSE 0 END) ,0) AS 'ZeroDays0' 

吧？

Answer 3

CASE WHEN T.TranAge> = 0和CASE WHEN T.TranAge < 1 THEN 1

這應該是

CASE 
    WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1 
... 

這是用於指定使用CASE化合物的條件的語法...當構建。

Answer 4

你在錯誤的地方,0這裏，改變這種：

isnull(sum(CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END,0)) 

到：

isnull(sum(CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END), 0) 

而且，你case陳述是錯誤的，不應該有另一個case在條件。改變看起來像這樣的人;

CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END 

到：

CASE WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1 ELSE 0 END 

Answer 5

請在您的案件條件的變化：

, isnull(sum(CASE WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1 ELSE 0 END),0) AS 'ZeroDays0' 

Answer 6

爲您傳遞,0作爲SUM函數的參數ZeroDays0列，而不是ISNULL。
