SQL服務器：在插入

Question

使用情況我有以下SQL：

;WITH DatesCTE AS 
(
    SELECT CAST('2016-01-01' AS DATE) AS [workingDays] 

    UNION ALL 

    SELECT DATEADD(DAY, 1, workingdays) 
    FROM DatesCTE 
    WHERE DATEADD(DAY, 1, workingdays) < '2017-01-01' 
) 
insert into dbo.tWorkingDays 
    (date, 
    CASE ((DATEPART(dw, workingDays) + @@DATEFIRST) % 7) NOT IN (0, 1) when TRUE THEN 1, 
     ELSE 0 
    END 
    ) 
SELECT * 
FROM DatesCTE 
WHERE ((DATEPART(dw, workingDays) + @@DATEFIRST) % 7) NOT IN (0, 1) 
OPTION (MAXRECURSION 366) 

和下表：

CREATE TABLE [dbo].[tWorkingDays] 
(
    [date] [date] NOT NULL, 
    [is_business_day][bit] NOT NULL DEFAULT 1, 

    CONSTRAINT [PK_tWorkingDays] 
     PRIMARY KEY CLUSTERED ([date] ASC) 
) ON [PRIMARY] 

當我嘗試執行請求我看到以下內容：

Msg 156，Level 15，State 1，Line 14
關鍵字'CASE'附近的語法不正確。

我做錯了什麼？

;WITH DatesCTE AS (
     SELECT CAST('20160101' AS DATE) AS [workingDays] 
     UNION ALL 

     SELECT DATEADD(DAY, 1, workingdays) 
     FROM DatesCTE 
     WHERE DATEADD(DAY, 1, workingdays) < '2017-01-01' 
    ) 
    INSERT INTO dbo.tWorkingDays (date, is_business_day) 
    SELECT *, CASE WHEN (DATEPART(dw, workingDays) + @@DATEFIRST) % 7 NOT IN (0, 1) THEN 1 ELSE 0 END 
    FROM DatesCTE 
    --WHERE (DATEPART(dw, workingDays) + @@DATEFIRST) % 7 NOT IN (0, 1) 
    OPTION (MAXRECURSION 366)

看起來像是已經將選定列表（要插入的值）與字段列表（要插入的字段）混合在一起。它應該是這樣的：

;WITH DatesCTE 
AS (

    SELECT CAST('2016-01-01' AS DATE) AS [workingDays] 
    UNION ALL 

    SELECT DATEADD(DAY, 1, workingdays) 
    FROM DatesCTE 
    WHERE DATEADD(DAY, 1, workingdays) < '2017-01-01' 

) 
insert into dbo.tWorkingDays 
    (date, is_business_day) 
SELECT workingDays, 
    CASE WHEN ((DATEPART(dw, workingDays) + @@DATEFIRST) % 7) NOT IN (0, 1) THEN 1 ELSE 0 
    END 
FROM DatesCTE 
WHERE ((DATEPART(dw, workingDays) + @@DATEFIRST) % 7) NOT IN (0, 1) 
OPTION (MAXRECURSION 366) 

你可能不希望在WHERE子句，並在同一查詢的情況下，但所引用的代碼應該至少解決語法錯誤。
