Executing SQL Server Agent Job from a stored proce

问题:

Need to have a stored procedure that calls a SQL Server Agent Job and returns whether or not the job ran successfully or not.

So far I have

CREATE PROCEDURE MonthlyData
AS
EXEC msdb.dbo.sp_start_job N'MonthlyData'

WAITFOR DELAY '000:04:00'

EXEC msdb.dbo.sp_help_jobhistory @job_name = 'MonthlyData'
GO

Which starts the job, whats the best way to get back if the job ran successfully or not?

Ok made an edit and used WAITFOR DELAY as the job normally runs between 3-4 mins never longer than 4. Does the job but is there a more efficient way to do it?

回答1:

You can run the query:

EXEC msdb.dbo.sp_help_jobhistory 
    @job_name = N'MonthlyData'

It'll return a column run_status. Statuses are:

 0 - Failed
 1 - Succeeded
 2 - Retry
 3 - Canceled         

More info on MSDN

EDIT: You might want to to poll your job and make sure it's executed. You can get this information from sp_help_job procedure. When this procedure returns status of 4 it means the job is idle. Then it's safe to check for it's run status.

You can poll using following code:

DECLARE @job_status INT
SELECT @job_status = current_execution_status FROM OPENROWSET('SQLNCLI', 'Server=.;Trusted_Connection=yes;','exec msdb.dbo.sp_help_job @job_name = ''NightlyBackups''')

WHILE @job_status <> 4
BEGIN
    WAITFOR DELAY '00:00:03'
    SELECT @job_status = current_execution_status FROM OPENROWSET('SQLNCLI', 'Server=.;Trusted_Connection=yes;','exec msdb.dbo.sp_help_job @job_name = ''NightlyBackups''')
END

EXEC msdb.dbo.sp_help_jobhistory 
    @job_name = N'NightlyBackups' ;
GO

This code will check for the status, wait for 3 seconds and try again. Once we get status of 4 we know the job is done and it's safe to check for the job history.

For all you guys who are not allowed to use the OPENROWSET command, this might help. I found the start for my solution here:

http://social.msdn.microsoft.com/Forums/en-US/89659729-fea8-4df0-8057-79e0a437b658/dynamically-checking-job-status-with-tsql

This relies on the fact that some columns of the msdb.dbo.sysjobactivity table first get populated after the job finishes in one way or the other.

-- Start job
DECLARE @job_name NVARCHAR(MAX) = 'JobName'
EXEC msdb.dbo.sp_start_job @job_name = @job_name


-- Wait for job to finish
DECLARE @job_history_id AS INT = NULL

WHILE @time_constraint = @ok
BEGIN
    SELECT TOP 1 @job_history_id = activity.job_history_id
    FROM msdb.dbo.sysjobs jobs
    INNER JOIN msdb.dbo.sysjobactivity activity ON activity.job_id = jobs.job_id
    WHERE jobs.name = @job_name
    ORDER BY activity.start_execution_date DESC

    IF @job_history_id IS NULL
    BEGIN
        WAITFOR DELAY '00:00:10'
        CONTINUE
    END
    ELSE
        BREAK
END


-- Check exit code
SELECT history.run_status
FROM msdb.dbo.sysjobhistory history
WHERE history.instance_id = @job_history_id

You might want to put in some checks for how long the WHILE-loop is allowed to run. I chose to keep that part out of the example.

I might be a bit late but I found that the following query worked for me. It will give execution time and execution end time. You can alter it to get status as well.

SELECT 
    job.name, 
    job.job_id, 
    job.originating_server, 
    activity.run_requested_date, 
    activity.stop_execution_date, 
    DATEDIFF( SECOND, activity.run_requested_date, activity.stop_execution_date ) as Elapsed 
FROM msdb.dbo.sysjobs_view job 
JOIN msdb.dbo.sysjobactivity activity ON job.job_id = activity.job_id 
JOIN msdb.dbo.syssessions sess ON sess.session_id = activity.session_id 
JOIN 
( 
    SELECT 
    MAX( agent_start_date ) AS max_agent_start_date 
    FROM 
    msdb.dbo.syssessions 
) sess_max 
ON sess.agent_start_date = sess_max.max_agent_start_date 
WHERE run_requested_date IS NOT NULL 
--AND stop_execution_date IS NULL 
AND job.name = @JobName

Here is a a script that will check the status of a job and will run it if it is not running already.

declare @xp_results table (
job_id                UNIQUEIDENTIFIER NOT NULL,
last_run_date         INT              NOT NULL,
last_run_time         INT              NOT NULL,
next_run_date         INT              NOT NULL,
next_run_time         INT              NOT NULL,
next_run_schedule_id  INT              NOT NULL,
requested_to_run      INT              NOT NULL, -- BOOL
request_source        INT              NOT NULL,
request_source_id     sysname          COLLATE database_default NULL,
running               INT              NOT NULL, -- BOOL
current_step          INT              NOT NULL,
current_retry_attempt INT              NOT NULL,
job_state             INT              NOT NULL)

DECLARE @job_id uniqueidentifier ;
select @job_id = job_id from msdb.dbo.sysjobs where name = 'Job1';
insert into @xp_results
EXEC master.dbo.xp_sqlagent_enum_jobs 1, sa, @job_id

select case when running = 1 then 'Currently Running' else '' end as running, 
case job_state 
    when 0 then 'Not Idle or Suspended'
    when 1 then 'Executing Job'
    when 2 then 'Waiting For Thread'
    when 3 then 'Between Retries'
    when 4 then 'Idle'
    when 5 then 'Suspended'
    when 6 then 'WaitingForStepToFinish'
    when 7 then 'PerformingCompletionActions'
end as job_state
from @xp_results

IF (select running from @xp_results) <> 1
    EXEC msdb.dbo.sp_start_job 'Job1'
