Hi all,
i have SSIS package ..its needs run every day .for that we were schedule a job for ssis..
but we need when package going to run that time we have to take data, besed on last time processed date..for that am using msdb data base to get process date ..but am not yet schedule a job am going to do 1st time..
insde the package am using this query using execte sql task 
SELECT     CASE WHEN DateDiff(Day, CONVERT(DATETIME, LEFT(MAX(H.run_date), 8)), GetDate()) = 0 THEN 30 ELSE DateDiff(Day, CONVERT(DATETIME, LEFT(MAX(H.run_date), 8)), GetDate()) END   AS Dates
FROM            dbo.sysjobhistory AS H INNER JOIN
                         dbo.sysjobs AS J ON H.job_id = J.job_id
WHERE        (H.run_status = 1) ..
if job already ran means its was working fine.if job not yet scheduled means its giving error...

Try this one on:
SELECT COALESCE(dates,fallBack) AS dates, name
FROM (
SELECT 30 AS fallBack
) b
LEFT OUTER JOIN (
SELECT CASE WHEN DateDiff(Day, CONVERT(DATETIME, LEFT(MAX(H.run_date), 8)), GetDate()) = 0 THEN 30
ELSE DateDiff(Day, CONVERT(DATETIME, LEFT(MAX(H.run_date), 8)), GetDate())
END AS Dates,
j.name
FROM dbo.sysjobhistory AS H
INNER JOIN dbo.sysjobs AS J
ON H.job_id = J.job_id
WHERE H.run_status = 1
GROUP by j.name
) a
ON b.fallBack = b.fallBack
You might want to consider filtering on j.name or j.job_id to get the info for the specific job.
