sql problem trying to get only 1 record.

I am writing an rpg program connecting to sql server that joins several files together. One of the files has or potentially can have multiple records and I only want to select the record with the most current hold date.

Here is my original sql statement

sqlstmt = 'select * from gisowner.jtx_jobs a +
left outer join gisowner.jtx_job_holds b +
on a.Job_id = b.Job_id +
left outer join gisowner.JTX_HOLD_TYPES c +
on b.HOLD_TYPE_ID = c.id +
join gisowner.wmx_workflow d +
on a.job_id = d.job_id where a.job_Type_ID = 1 and +
convert(char(10),a.End_date,120) >= ? +
and convert(char(10),a.End_date,120) <= ? +
and convert(char(10),a.end_date,120) +

convert(char(10),a.due_date,120) order by a.job_id ' ;

Gisowner.jtx_job_holds can have multiple records with different holddates.
With this statement I am getting some duplicates.

So I'm testing now within sql server itself and here is what I currently have.

select a.JOB_ID,a.DESCRIPTION, d.receiveddate, max(b.HOLD_DATE) from
workflowmanager.gisowner.jtx_jobs a left outer join workflowmanager.gisowner.jtx_job_holds b
on a.Job_id = b.Job_id left outer join workflowmanager.gisowner.JTX_HOLD_TYPES c
on b.HOLD_TYPE_ID = c.id join workflowmanager.gisowner.wmx_workflow d
on a.job_id = d.job_id
where a.job_Type_ID = 1
and (convert(char(10),a.End_date,120) >= '2014-01-01'
and convert(char(10),a.End_date,120) <= '2014-03-31' )
and convert(char(10),a.end_date,120) > convert(char(10),a.due_date,120)
group by a.job_id, a.description, d.receiveddate, b.hold_date


The file names are slightly different, but its simply because sql server is making me add the database name.
I've also only included a few of the fields I actually need for testing purposes.
I still get multiple records from gisowner.jtx_job_holds but I'm not sure why


JOB_ID DESCRIPTION receiveddate (No column name)
32002 2130537 2013-12-24 12:00:00.0000000 NULL
32003 2130430 2013-12-23 12:00:00.0000000 2014-01-13 14:56:13.0000000
32004 2130433 2013-12-23 12:00:00.0000000 2014-01-13 14:31:30.0000000
32004 2130433 2013-12-23 12:00:00.0000000 2014-01-13 14:51:18.0000000
