Long running transaction alert configuration

Hi, I am trying to setup a alert for long running transactions. The alert is setup to run the below job and then further run the stored procedure to collate data and email. However the SQL_Text column is most of the time blank in the email however I can see results in destination table. Is there any config that I can add here to make sure it is always there. The data is being captured from the Sp_whoisactive. **SQL Agent Job Step**: ------------------------------------------------------------------ DECLARE @AlertingThresholdMinutes int = 1200; SET NOCOUNT ON; DECLARE @LongestRunningTransaction int; SELECT @LongestRunningTransaction = MAX(DATEDIFF(n, dtat.transaction_begin_time, GETDATE())) FROM sys.dm_tran_active_transactions dtat INNER JOIN sys.dm_tran_session_transactions dtst ON dtat.transaction_id = dtst.transaction_id; IF ISNULL(@LongestRunningTransaction,0) > @AlertingThresholdMinutes BEGIN DECLARE @destination_table varchar(500) = 'WhoIsActive', @destination_database sysname = 'DBADB', @schema varchar(max), @SQL nvarchar(4000), @parameters nvarchar(500), @exists bit; SET @destination_table = @destination_database + '.dbo.' + @destination_table; --create the logging table IF OBJECT_ID(@destination_table) IS NULL BEGIN; EXEC sp_WhoIsActive @get_transaction_info = 1, @get_outer_command = 1, @get_plans = 1, @return_schema = 1, @schema = @schema OUTPUT; SET @schema = REPLACE(@schema, '', @destination_table); EXEC(@schema); END; --purge older data SET @SQL = 'DELETE FROM ' + @destination_table +' '; EXEC (@SQL); --collect activity into logging table EXEC dbo.sp_WhoIsActive @get_transaction_info = 1, @get_outer_command = 1, @get_plans = 1, @destination_table = @destination_table; Exec [DBADB].[dbo].[Long_Running_Query_Alert] END **Stored Procedure : Long_Running_Query_Alert** ------------------------------------------------------------------ DECLARE @tableHTML NVARCHAR(MAX) ; SET @tableHTML = N'

A couple of things I can suggest: 1. Replace with in the SQL Server Agent job -- ![alt text][1] (assuming it's just the same issue that I had in #2 but just in case) 2. Add to the stored procedure right after you SET @tableHTML -->![alt text][2] . This will clean up the HTML string a bit. (I could not even used the text in the post because these strings were stripped out, had to use the picture) HTH, Denis [1]: /storage/temp/4350-capture2.jpg [2]: /storage/temp/4348-capture.jpg

Thanks Denis. It worked!! :-). Step 1 was already there but somehow a part of it was taken away when I originally submitted it. Step 2 fixed the missing SQL issue. Thank again for your help. Much appreciated.
