SQL 動態查詢錯誤（列名對於不是列名的值無效）

Question

動態查詢拋出錯誤，指出無效的列名“總部”。 不知道為什么會拋出那個錯誤。 如果我取出 With 塊末尾的 where 語句，它運行良好，所以我認為它在那里壞了。 請幫忙。 我已經嘗試過重新啟動所有內容並刷新緩存。 在我使用 " 而不是 ' 的地方看不到任何錯誤。

DECLARE @StartDate DATE = '10/25/2021';
DECLARE @EndDate DATE;
DECLARE @DynamicQuery AS NVARCHAR(MAX);
DECLARE @ColumnList AS NVARCHAR(MAX);
DECLARE @LocationNameFromApp AS VARCHAR(50);
DECLARE @SDstr as NVARCHAR(10);
DECLARE @EDstr as NVARCHAR(10);

Set @EndDate = DATEADD(DAY,13,@StartDate);
SET @SDstr = CONVERT(VARCHAR(10), @StartDate, 120);
SET @EDstr = CONVERT(VARCHAR(10), @EndDate, 120);
SET @LocationNameFromApp = 'Headquarters';

-- populate column list 
WITH DateRange(DateData) AS 
(
    SELECT @StartDate as Date
    UNION ALL
    SELECT DATEADD(DAY,1,DateData)
    FROM DateRange 
    WHERE DateData < @EndDate
)
SELECT @ColumnList = ISNULL(@ColumnList + ',', '')
        + QUOTENAME(FORMAT(DateData, 'MM/dd/yyyy'))
FROM DateRange
OPTION (MAXRECURSION 300);


set @DynamicQuery = '

WITH Schedule AS (
    SELECT

        R.RotationName,
        D.FullDateUSA,

        INNER JOIN dbo.Locations L on F.LocationID = L.LocationID
    WHERE LocationName='+@LocationNameFromApp+' AND FullDateUSA >= '+@SDstr+' AND FullDateUSA <= '+@EDstr+'
)

SELECT * INTO dbo.'+@LocationNameFromApp+'SchedDays
FROM Schedule
    PIVOT (MAX(ShiftName) FOR FullDateUSA IN ('+@ColumnList+')) P  
    
ALTER TABLE dbo.'+@LocationNameFromApp+'SchedDays ADD ID int identity(1,1) not null

ALTER TABLE dbo.'+@LocationNameFromApp+'SchedDays ADD CONSTRAINT '+@LocationNameFromApp+'pk_ID primary key(ID)

我假設是因為您在這里將其設置為常量 -

SET @LocationNameFromApp = 'Headquarters';

動態查詢將其轉換為LocationName=Headquarters而不是LocationName='Headquarters' 。

嘗試更改變量的設置，如下所示 -

SET @LocationNameFromApp = '''Headquarters''';

所以它將被轉換為LocationName='Headquarters' 。
