Not sure what you really want. Here is an example script to list the job execution history for the job "syspolicy_purge_history":
USE [msdb];
GO
SELECT j.*, jh.*
FROM [dbo].[sysjobs] AS j
INNER JOIN [dbo].[sysjobhistory] AS jh
ON j.job_id = jh.job_id
WHERE j.name = 'syspolicy_purge_history' -- Job Name
AND jh.step_id = 0 -- Job level
ORDER BY jh.run_date DESC;
GO
