SQL Script to send a file by FTP

This Stored procedure send a file by FTP.

Check if SQL Agent has access to the file and FTP server.

The little trick is to create a file that will run. It can have conflicts easily because filename is always the same. Next version will be with random name. 

Use this code carefully, it is not 100% safe.

USE master;
 PRINT '-- Server name: '+@@servername

         WHERE id = object_id(N'[dbo].[sp_FtpSendFile]')
             AND OBJECTPROPERTY(id, N'IsProcedure') = 1
