Question

我有一个像这样定义的表：

CREATE TABLE [ThirdPartyData].[AdsTxtFile](
    [DomainHostName] [varchar](200) NOT NULL,
    [Expires] [datetime] NOT NULL,
    [Advertiser] [varchar](200) NOT NULL,
    [AdvertiserId] [varchar](50) NOT NULL,
    [AdvertiserType] [varchar](20) NOT NULL,
    [TAGId] [varchar](100) NULL,
    CONSTRAINT [PK_AdsTxtFile] PRIMARY KEY CLUSTERED 
        (
        [DomainHostName] ASC,
        [Advertiser] ASC,
        [AdvertiserId] ASC
        )
)

我正在尝试将文件批量插入此表。该文件的前几行是：

roadandtrack.com(TAB)9/13/2017 12:00:00 AM(TAB)google.com(TAB)pub-1301581561755234(TAB)DIRECT(TAB)f08c47fec0942fa0

我已将文件中的标签字符替换为(TAB)，以便在此帖子中显示，但它们是文件本身中的实际标签字符。文件中的每一行都以换行符结束。

我在SQL Server中运行以下命令：

BULK INSERT [ThirdPartyData].[AdsTxtFile] FROM 'MyFileLocation.txt'

我得到如下例外：

System.Data.SqlClient.SqlException (0x80131904): Bulk load data conversion error (truncation) for row 1, column 6 (TAGId).
   at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
   at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose)
   at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady)
   at System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async, Int32 timeout, Boolean asyncWrite)
   at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(TaskCompletionSource`1 completion, String methodName, Boolean sendToPipe, Int32 timeout, Boolean& usedCache, Boolean asyncWrite, Boolean inRetry)
   at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()

...现在我正在摸不着头脑，因为我的理解是标签和换行符是批量插入命令的默认终止符，第一行TAGId的“f08c47fec0942fa0”肯定没有超过100个字符，所以我不知道问题是什么。谁能告诉我我做错了什么？

Answer 1

好吧，我读过的文档建议默认行终止是换行符或换行符（\ n）......但似乎并非如此。一旦我将行结束更改为回车换行（\ r \ n），它就能正常工作。

批量加载转换错误（截断）......遗漏了一些明显的东西
