sometimes a system proc calls many tables/views

example:
exec msdb..sp_help_job @job_name=  'jobname'

return 4 result sets. would they always relate to 4 different system views, necessarily?

then we can query that particular one alone.. or insert into temp table etc

Thanks

OK. Thanks.

I need to compile a list of all the steps in each jobs and which database they use.

so the second result set is of interest to me - StepName and DatabaseName. If I can just get that system viewname,
then I go straight to it.

The outputs need not be from particular views all the time.

Execute this on sql server msdb database:

sp_helptext sp_help_job

You will notice from where the resultsets are retrieved, and use the outputs as you need to temp tables. You could search for 'result' in the text there.

>> I need to compile a list of all the steps in each jobs and which database they use.

I suppose, the simpler way would be to script out the job and then anaylze it completely. Because in some cases, a particular step in a job might be scheduled to run across all databases.

Hope I answered in sync with your question. Else kindly give me more inputs.

Table: msdb.dbo.sysjobsteps
column: database_name

will give you the starting db for each step.

Of course it's possible that other dbs will be referenced in the T-SQL.
