Sql server 2008 SQL Server:大容量加载数据转换错误

我试图将一些数据从固定宽度的文本文件加载到视图中，插入被instead of触发器截获

应该输出触发器中插入的值的调试选择没有被触发，因此我怀疑失败点是大容量插入本身

详情如下: 以下是我正在使用的：

启动大容量插入命令如下所示：

BULK INSERT Staging.vViewSolelyForInsertion
FROM 'X:\path\to\datafile.txt'
WITH
(
    FORMATFILE='X:\path\to\formatfile.xml',
    FIRE_TRIGGERS,
    ERRORFILE='X:\path\to\Error.log'
)

创建用于Staging.vviewsolelyforinsert的命令：

CREATE VIEW Staging.vViewSolelyForInsertion
AS
SELECT
    CONVERT(NVARCHAR(4), NULL, 0) AS Door,
    CONVERT(NVARCHAR(9), NULL, 0) AS Chair,
    CONVERT(NVARCHAR(24), NULL, 0) AS Office,
    CONVERT(NVARCHAR(10), NULL, 0) AS Telephone,
    CONVERT(NVARCHAR(4), NULL, 0) AS Cup,
    CONVERT(NVARCHAR(1), NULL, 0) AS Headphones,
    CONVERT(NVARCHAR(20), NULL, 0) AS Mouse,
    CONVERT(NVARCHAR(12), NULL, 0) AS Keyboard

用于创建触发器的CREATE命令

CREATE TRIGGER Staging.ON_INSERT_Staging_vViewSolelyForInsertion
ON Staging.vRefViewSolelyForInsertion
BEGIN

    SELECT * FROM INSERTED -- debug, the error message appears before this point.

    /*
        This table exists to generate the InternalId.
    */  
    DECLARE @tbl TABLE
    (
        InternalId UNIQUEIDENTFIER NOT NULL DEFAULT NEWID(),
        Door,
        Chair,
        Office,
        Telephone,
        Cup,
        Headphones,
        Mouse,
        Keyboard
    )

    INSERT INTO @tbl
    (
        Door,
        Chair,
        Office,
        Telephone,
        Cup,
        Headphones,
        Mouse,
        Keyboard
    )
    SELECT
        i.Door,
        i.Chair,
        i.Office,
        i.Telephone,
        i.Cup,
        i.Headphones,
        i.Mouse,
        i.Keyboard
    FROM INSERTED i

    SELECT * FROM @tbl -- 2nd debug

    INSERT INTO Staging.ActualTable
    (
        InternalId,
        Door,
        Chair,
        Office,
        Telephone,
        Cup,
        Headphones,
        Mouse,
        Keyboard
    )
    SELECT
        -- Lots of processing goes on here. 
        t.InternalId,
        ProcessDoor(t.Door, t.InternalId),
        ProcessChair(t.Chair, t.InternalId),
        ProcessOffice(t.Office, t.InternalId),
        ProcessTelephone(t.Telephone, t.InternalId),
        ProcessCup(t.Cup, t.InternalId),
        ProcessHeadphones(t.Headphones, t.InternalId),
        ProcessMouse(t.Mouse, t.InternalId),
        ProcessKeyboard(t.Keyboard, t.InternalID)
    FROM @tbl t

    DELETE FROM @tbl

END

数据文件由\r\n终止行组成，数据字段之间没有分隔符，并以unicode格式保存。每行长度为138个字符，加上行末的\r\n字符

我得到的错误如下：

第1行第2列（椅子）的批量加载数据转换错误（截断）

ImportFile.xml中的字段长度与ImportFile.xml中的列长度相同，与Staging.vViewSolelyForInsertion中的nvarchar长度相同。 如上所述（我知道这是很久以前的事了），触发器中的第一条调试语句没有执行，这让我认为是大容量插入失败了

提前谢谢

所有这些工作都是徒劳的。将xsi:type设置为CharFixed而不是NCharFixed解决了这个问题，即使我使用的是Unicode。现在我正在处理数据中的奇怪字符（在输入文件中显示为普通文本）
