好的，我已经与这个问题作斗争了将近一个星期，我一生都无法弄清楚问题是什么。

问题：BCP 实用程序创建 txt 文件，但之后没有任何反应。该文件只是坐在那里并且是空白的。BCP 几乎挂起。我必须结束进程才能停止它。BCP 命令位于存储过程中，该存储过程位于作业步骤中的事务中。如果我使用 sproc 本身并在 Management Studio 中运行它，则该文件的创建没有问题。如果我创建一个 SQL 作业并只放置运行 BCP 命令的存储过程，它也可以工作。

这是工作步骤：

BEGIN TRANSACTION

BEGIN TRY

EXEC dbo.DataManipulation1
EXEC dbo.DataManipulation2
EXEC dbo.DataManipulation3
EXEC dbo.DataManipulation4
EXEC dbo.DataManipulation5

EXEC dbo.spCreateFiles 0

EXEC dbo.spSendEmail 'PASS'

COMMIT TRANSACTION
END TRY

BEGIN CATCH

ROLLBACK TRANSACTION

EXEC dbo.spGetDatabaseErrorInfo
EXEC dbo.spCreateFiles 1
EXEC dbo.spSendEmail 'FAIL'
END CATCH

这是 spCreateFiles 存储过程。高级概述：Sproc 生成系统文件夹，然后对 txt 文件进行查询。而已。如果传递给sproc的参数为0，它将根据sproc的执行生成文件，如果参数不为0，则生成空白文件。一共4个文件。BCP 命令的用户名和密码因显而易见的原因而被删除。从我在线阅读的一些内容来看，这可能是因为某些东西正在锁定文件……可能是存储过程或 SQL 作业，甚至是事务，然后当 BCP 实用程序尝试使用它时，什么也没有发生。

我弄清楚了这个问题。

事务打开时，我无法使用 BCP 实用程序。我必须提交事务，然后使用 BCP。
