How long has the current SPID/Agent Job been running

Question

I have a SQL Agent Job that has 15 steps. Each step executes the same CLEANUP sproc against a database. STEP1 executes CLEANUP against DB1, STEP2 executes CLEANUP against DB2, etc. These 15 databases all have the exact same schema (that was the design
decision - not going to change).  The job can run for days. I want to have a MAXMINUTESTORUN configuration (probably set to 4 hours) that the sprocs will check and when that is exceeded the sprocs will nicely terminate and then pick up  again
the next time. I want to be able to ask in the sproc, how long has the spid/agent job been running. How is the best way to do this?

Answer 1

Well, the idea for that, 
the clean up always runs first on the database it never before and then it will run against the database that has oldest 'Lastrun". you can change this logic if you need.
Using the demo scripts above, try this ...after the scheduling the job.
1. run the job once..it will run the procedure for testA
2.check the output of select * from msdb.dbo.cleanupjob
3. run the job again..it will run the procedure for testB(the reason it picks this is because the cleanup procedure never ran for database testb)
4.check the output of select * from msdb.dbo.cleanupjob
5. run the job again..it will run the procedure for testA(the reason it picks this is because the cleanup procedure ran for database testb atleast once and 
will the pick the  oldest "last run " database)
6.check the output of select * from msdb.dbo.cleanupjob
you can also ,,replace this block
select top 1 @a= databasename from
(select top 1 1 source,databasename from cleanupjob
where (lastrun is null)
union
select top 1 2 source,databasename from cleanupjob
where (lastrun in (select min(lastrun) from cleanupjob where lastrun is not null))
order by source) A
with 
select top 1 @a=databasename from msdb.dbo.cleanupjob where isnull(lastrun,'19000101') in (select min(isnull(lastrun,'19000101')) from msdb.dbo.cleanupjob)
order by id
Hope it Helps!!
