Determine whether a job is running in SQL Server

Select step_id, run_status, run_date as rundate
-- A. run_time, .*
From MSDB. DBO. sysjobhistory
Inner join MSDB. DBO. sysjobs B on A. job_id = B. job_id
Where B. Name = 'pcdbi'
Order by run_date DESC, step_id ASC

Job execution status run_status:
0 = failed
1 = successful
2 = retry
3 = Cancel
4 = in progress
