I have used below query for downloading a file from FTP.
SP is executes successfully but files are not getting downloaded.

Can any body help me to download file from FTP through SQL Stored Procedure?

Create procedure s_ftp_GetFile
@FTPServer	varchar(128) ,
@FTPUser	varchar(128) ,
@FTPPWD		varchar(128) ,
@FTPPath	varchar(128) ,
@FTPFileName	varchar(128) ,
@SourcePath	varchar(128) ,
@SourceFile	varchar(128) ,
@workdir	varchar(128)
as
/*
exec s_ftp_GetFile 	
		@FTPServer = 'www.myftpsite.com' ,
		@FTPUser = 'myuser' ,
		@FTPPWD = 'mypwd' ,
		@FTPPath = '' ,
		@FTPFileName = 'myfile.html' ,
		@SourcePath = 'c:\vss\mywebsite\' ,
		@SourceFile = 'myfile.html' ,
		@workdir = 'c:\temp\'

declare	@cmd varchar(1000)
declare @workfilename varchar(128)
	
	select @workfilename = 'ftpcmd.txt'
