Question

我试图将固定宽度文本文件中的某些数据加载到视图中，插入的是由替代触发器拦截的。

应该在触发器中输出来自INSERTED的值的调试选项不会被触发，所以我怀疑失败点是批量插入本身。

以下是详细信息：以下是我正在使用的内容：

初始批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'
)

用于Staging.vViewSolelyForInsertion的CREATE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

这是我使用

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，加上行尾的\ r \ n。

我得到的错误如下：

第1行第2列（主席）的批量加载数据转换错误（截断）。

ImportFile.xml中的字段长度与ImportFile.xml中的列长度与Staging.vViewSolelyForInsertion中的nvarchar长度相同。如上所述（我很久以前就知道了），触发器中的第一个调试语句没有执行，导致我认为它是BULK INSERT失败的原因。

提前致谢！

这一切都无济于事。将xsi：type设置为CharFixed而不是NCharFixed解决了这个问题，即使我正在使用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）。
