使用存储过程和大容量复制程序（bcp）实用程序通过FTP将文件从一台SQL Server移动到另一台SQL Server

以下是我试图编写的过程：

首先，我需要在SQL Server 1中生成一个文件，其中包含一些可以从同一服务器查询的数据

然后我需要将文件从SQLServer1移动到FTP服务器，从那里我需要从SQLServer2获取文件的详细信息

---

在

bcp

实用程序的帮助下，我该如何做？

在sql server中创建一个包含查询数据的文件

    DECLARE @FileName varchar(1000),@bcpCommand varchar(1000),
            @FileGeneratePath varchar(100)
    DECLARE @exe_path4 VARCHAR(200) = ' cd C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\110\Tools\Binn & ';

    Set @FileGeneratePath = '\\192.168.XX.XXX\Files\'
    Set @FileName = REPLACE('SampleFile'+ CONVERT(varchar(10),GETDATE(),100)+'.xls',' ','') --'\\192.168.29.111\Files\authors'+ Convert(varchar(40),Getdate(),121) + '.csv'

    SET @bcpCommand = @exe_path4 +' bcp.exe "SELECT top 10 * from [192.168.XX.XXX].DATABASE.dbo.FamilyAccountDetails where Convert(varchar(10),LastUpdatedon,100)  > Convert(varchar(10),Getdate()-30,100)" queryout "' 
    SET @bcpCommand = @bcpCommand + @FileGeneratePath + @FileName + '" -c -t"|" -Uusername -Ppassword -S192.168.XX.XXX'

    EXEC master..xp_cmdshell @bcpCommand, no_output

exe_path4是bcp exe的路径。 有关bcp实用程序的更多详细信息。而且

xp_cmdshell是一个扩展存储过程，它允许您通过SQL语句执行操作系统命令。扩展存储过程是用C++语言编写的程序，然后附加到SQL Server实例中。一旦附加，它们就可以像常规存储过程一样被引用

xp\u cmdshell中的

no\u输出

类似于

set nocount on

将文件从sql server移动到ftp的存储过程

在下面的存储过程中，我创建了一个文本文件，在命令提示符下执行，将文件移动到ftp，反之亦然。这两个文件都是在SQL Server临时文件夹中生成的，而不是在本地临时文件夹中生成的。您还可以为文件生成指定特定文件夹
