SQL – How to get the status of an SQL job (sp_help_job)

 

Here is a simple script using sp_help_job to display information about jobs that are used by SQL Server Agent:

USE msdb
EXEC dbo.sp_help_job @JOB_NAME = ‘JOB_NAME’, @job_aspect=‘JOB’

Look for ‘current_execution_status’ to get the status of the job.

1 = Executing.
2 = Waiting for thread.
3 = Between retries.
4 = Idle.
5 = Suspended.
7 = Performing completion actions.

 

Here is a more detailed script to store the results of sp_help_job into a table and query the results:

DECLARE @JOBNAME VARCHAR(100)
SET @JOBNAME = ‘JOB_NAME’

CREATE TABLE #JOBSTATUS(
       job_id uniqueidentifier 
      ,originating_server nvarchar(30)
      ,name sysname
      ,enabled tinyint
      ,description nvarchar(512)
      ,start_step_id int
      ,category sysname
      ,owner sysname
      ,notify_level_eventlog int
      ,notify_level_email int
      ,notify_level_netsend int
      ,notify_level_page int
      ,notify_email_operator sysname
      ,notify_netsend_operator sysname
      ,notify_page_operator sysname
      ,delete_level int
      ,date_created datetime
      ,date_modified datetime
      ,version_number int
      ,last_run_date int
      ,last_run_time int
      ,last_run_outcome int
      ,next_run_date int
      ,next_run_time int
      ,next_run_schedule_id int
      ,current_execution_status int
      ,current_execution_step sysname 
      ,current_retry_attempt int
      ,has_step int
      ,has_schedule int
      ,has_target int
      ,type int     
); 

INSERT INTO #JOBSTATUS
EXEC dbo.sp_help_job
 @JOB_NAME = @JOBNAME
,@job_aspect=‘JOB’

SELECT CASE current_execution_status
WHEN ’0′ THEN ‘Returns only those jobs that are not idle or suspended. ‘        
WHEN ’1′ THEN ‘Executing.’        
WHEN ’2′ THEN ‘Waiting for thread.’       
WHEN ’3′ THEN ‘Between retries.’        
WHEN ’4′ THEN ‘Idle.’
WHEN ’5′ THEN ‘Suspended.’
WHEN ’6′ THEN ”
WHEN ’7′ THEN ‘Performing completion actions.’
ELSE ‘UNKNOWN’
END as ‘current_execution_status’
FROM #JOBSTATUS

DROP TABLE #JOBSTATUS

 

OUTPUT:

current_execution_status
——————————————————–
Idle.

SQL – How to get the day of the week

Using the DATEPART function to calculate the integer value of the day of the week.

select datepart(dw,getdate()) as DayOfWeekINT

Output:
DayOfWeekINT
————
2  

1 = Sunday
2 = Monday
3 = Tuesday
4 = Wednesday
5 = Thursday
6 = Friday
7 = Saturday

Using the DATENAME function to calculate the  day of the week.

select datename(dw,getdate()) as DayOfWeekCHAR

Output:
DayOfWeekCHAR
——————————
Monday

 

 

 

You can get the day of the week for a given date (MM/DD/YYYY) using:

select datepart(dw,’03/07/2011′) as DayOfWeekINT
select datename(dw,’03/07/2011′) as DayOfWeekCHAR
