當從表變量中使用列時出現「無效列」

Question

我試圖聲明一個表變量，然後將它加入到我在數據庫中創建的表中。每次嘗試將我的「NAME」字段插入到我的表中時，即使GNAME字段正常工作，我也會收到錯誤「Invalid Column Name "NAME"」。我在做什麼錯了，我該如何加入我NAME專欄？

DECLARE @Names TABLE 
(
    ID INT, 
    NAME VARCHAR(100), 
    GNAME VARCHAR(100) 
) 

INSERT INTO @Names 
(
    ID, 
    NAME, 
    GNAME 
) 

SELECT 
    CName.ID, 
    Ref.NAME, 
    Ref.GNAME 
FROM 
    @CurrentPositions AS CName 
LEFT OUTER JOIN 
    dbo.NameField AS Ref 
ON 
    CName.ID = Ref.ID 

    IF (OBJECT_ID('dbo.ReportTable', 'U') IS NOT NULL) 
    DROP TABLE dbo.ReportTable 

CREATE TABLE [dbo].[ReportTable] 
(
    [ID_NUMBER] [INT], 
    [NAME] [VARCHAR](150) 
    [GNAME] [VARCHAR](150) 
) 

INSERT INTO [dbo].[ReportTable] 
(
    ID_NUMBER, 
    NAME, 
    GNAME 
) 

SELECT 
    C.ID_NUMBER, 
    N.NAME, 
    N.GNAME 
FROM 
    @Names AS N 
INNER JOIN 
    @CurrentPositions AS C 
ON N.ID_NUMBER = C.ID_NUMBER

嘗試使用TEMP表：

CREATE TABLE #Names 
(
    ID INT, 
    NAME VARCHAR(100), 
    GNAME VARCHAR(100) 
) 

INSERT INTO #Names 
(
    ID, 
    NAME, 
    GNAME 
) 
SELECT 
    CName.ID, 
    Ref.NAME, 
    Ref.GNAME 
FROM 
    #CurrentPositions AS CName 
LEFT OUTER JOIN 
    dbo.NameField AS Ref 
ON 
    CName.ID = Ref.ID 

    IF (OBJECT_ID('dbo.ReportTable', 'U') IS NOT NULL) 
    DROP TABLE dbo.ReportTable 

CREATE TABLE [dbo].[ReportTable] 
(
    [ID_NUMBER] [INT], 
    [NAME] [VARCHAR](150) 
    [GNAME] [VARCHAR](150) 
) 

INSERT INTO [dbo].[ReportTable] 
(
    ID_NUMBER, 
    NAME, 
    GNAME 
) 

SELECT 
    C.ID_NUMBER, 
    N.NAME, 
    N.GNAME 
FROM 
    #Names AS N 
INNER JOIN 
    #CurrentPositions AS C 
ON N.ID_NUMBER = C.ID_NUMBER 

我假定你也將發生變化表變量@CurrentPositions到一個臨時表

只記得之後下降表你使用它們。

很可能您需要做的就是將您的字段名稱放在方括號中，例如，

INSERT INTO @Names 
(
    [ID], 
    [NAME], 
    [GNAME] 
) 

SELECT 
    CName.[ID], 
    Ref.[NAME], 
    Ref.[GNAME] 
FROM 
    @CurrentPositions AS CName 
LEFT OUTER JOIN 
    dbo.NameField AS Ref 
ON 
    CName.[ID] = Ref.[ID] 

如果仍不能解決問題，請發表您的@CurrentPositions和dbo.NameField表的模式。
