Microsoft SQL Server - Send e-mails with block notifications

Sometimes we need to send an e-mail when our SQL Server identify some blocking process.

The script below will help you. Just create a job, change the information of your mail profile, recipients, subject and body.

SET NOCOUNT ON;

DECLARE @blockingProcess INT

SELECT  @blockingProcess = COUNT (*)

FROM    sys.dm_tran_locks L

        JOIN sys.partitions P ON P.hobt_id = L.resource_associated_entity_id

        JOIN sys.objects O ON O.object_id = P.object_id

        JOIN sys.dm_exec_sessions ES ON ES.session_id = L.request_session_id

        JOIN sys.dm_tran_session_transactions TST ON ES.session_id = TST.session_id

        JOIN sys.dm_tran_active_transactions AT ON TST.transaction_id = AT.transaction_id

        JOIN sys.dm_exec_connections CN ON CN.session_id = ES.session_id

        CROSS APPLY sys.dm_exec_sql_text(CN.most_recent_sql_handle) AS ST

WHERE   resource_database_id = db_id()

if @blockingProcess != 0

    begin

        EXEC msdb.dbo.sp_send_dbmail

            @profile_name = 'myprofile',

            @recipients = 'myemail@email.com',

            @subject = 'My subject',

            @body = 'Blocking Process found.'

    end
