Hello and good morning to you all.
In my company I am tasked with writing a SQL query to perform a few actions for our DayEnd processing. First off a little bit of information.
Our DayEnd does not run every day skipping Saturday and Sunday. It always starts during the night after business hours so our database is ready for the next business day. At the end of the process it forwards the date ahead by one day. Monday night starts at 7 PM, but Tuesday/Wednesday/Thursday/Friday starting at 8 PM. Monday night starts a bit earlier as it is processing for Saturday and Sunday and can take a bit longer. Also Friday night into Saturday is different than the rest as it processes more than any other day and forwards the business day to Monday when DayEnd will be run again.
Here are the things I am looking to perform:
1. Automate the script. DayEnd process starts at 7 PM on Monday; 8 PM Tuesday, Wednesday, Thursday, Friday.
2. Log the progress of DayEnd. Create a database averaging the times that each Task will take.
3. If any DayEnd Task falls out of the expectations of when each task will finish send an email. Sometimes Tasks stall out and the process freezes on a Task without us finding out until hours later.
So those are basic goals right now and a good start. So! Here is the code I was given.
SELECT CONVERT(DATE,DLOG.BusinessDate) "Business Date"
,DPRTYPE.DayEndProcessTypeName
,DLOG.StartDtTm
,DLOG.FinishDtTm
,(DATEDIFF(second,DLOG.StartDtTm,DLOG.FinishDtTm)*1.00)/60 "Minutes"
FROM DATABASENAME.dbo.DayEndLog DLOG
INNER JOIN DATABASENAME.dbo.DayEndProcessType DPRTYPE
ON DLOG.DayEndProcessTypeId = DPRTYPE.DayEndProcessTypeId,
(SELECT '04/07/2054' "DDATE") AS "QDATE"
WHERE (CONVERT(DATE,DLOG.BusinessDate) BETWEEN QDATE.DDATE AND DATEADD(day,+2,QDATE.DDATE) AND NOT DLOG.DayEndProcessTypeId IN (90,100,110)) OR (CONVERT(DATE,DLOG.BusinessDate) BETWEEN DATEADD(day,+1,QDATE.DDATE) AND DATEADD(day,+3,QDATE.DDATE) AND DLOG.DayEndProcessTypeId IN (90,100,110))
ORDER BY DLOG.StartDtTm, DLOG.FinishDtTm ASCAnd here are the results. Sorry if the formatting is off.
Note: the Business Date is in the future as I'm running this on a test database server. Whenever DayEnd is run it pushes the business day ahead by one so that is why the year is 2054. However the Start and Finish days are correct.
Also I changed the process names to be ambiguous, sorry about that. But the timings are real.

So that is what I am trying to achieve; automate a way to monitor DayEnd and alert if a problem is detected.
Thanks for your help.
