Invoke exe file from Sql Server Stored Procedure

Hi Guys,
Recently need some sql statement which can invoked an EXE file from the specific directory. After a little bit searching I found as follows.


SET @DBNameRoot = DB_NAME()


declare @cmd as varchar(250)


SET @cmd = 'C:\Automailer\AutoMailerExporter.exe S ' + CAST(@ReportID AS VARCHAR) + ' ' + @DBNameRoot


exec master..xp_cmdshell @cmd 
Note: 

• S, @reportid, @dbnameroot - All these are command line argument 
• This may not work on express edition (I am not confirm, if somebody let me know please)
• You need to enable xp_cmdshell (How to do? please surf a little bit or I will post another day).

Thanks for reading, and happy coding....
