FTP files using SQL stored procedure

,

This stored procedure takes four parameters
1)file to ftp
2)server name or IP
3)ftp login
4)ftp password
SP will ensure that local file exists before continuing,
it will create and execute a batch file in order to push the file to the remote FTP server.

--exec example
EXEC dbo.up_FTPPushFile 'c:\temp\test.txt', 'server',
'user', 'password'

create proc up_FTPPushFile
@file_to_push varchar(255), 
@ftp_to_server varchar(255),
@ftp_login varchar(255), 
@ftp_pwd varchar(255) 
as
Set Nocount On
--STEP 0
--Ensure we can find the file we want to send.
Create table #FileExists (FileExists int, FileIsDir int, ParentDirExists int)
Insert #FileExists EXEC master.dbo.xp_fileexist @file_to_push

BEGIN
	Drop table #FileExists
	RAISERROR ('File %s does not exist. FTP process aborted.', 16, 1, @file_to_push)
	RETURN 1
END  
--STEP 1
--Create xxx.bat batch file using bcp utility, file path/name is the same as @file_to_push
--batch file will hold 4 records:
--1) login
--2) password
--3) ftp command and file to push
--4) exit command

--STEP 2
