0 Results Effecting Entire Query - sql

Question

I was wondering if there is a way to make a results from a JOIN of a subquery result a predefined entry.
The query below pulls in the MAX(ReceiveDate) for the uniqueID JobNo. However, if nothing has been received the entire result will not show up. There are several other joins that could have data.
--***SUB QUERY (Receiver)
JOIN
(
SELECT
MAX(cast(r.ReceiveDate as DATE)) as ReceiveDate,
por.JobNo
FROM
POReleases as por
INNER JOIN
Receiver as r on por.PONum = r.PONum
GROUP BY por.JobNo
) r
ON r.JobNo = o.JobNo
The query will ultimately pull in data from purchase orders, result the most recent date, and the receiver with its most recent date based on the JobNo.
If nothing is received then result 'Whatever' or NULL. Anything.
The entire query is below:
DECLARE #now DATETIME
DECLARE #90daysago DATETIME
SET #now = GETDATE()
SET #90daysago = DATEADD(day, -90, #now)
;with cte as
(
SELECT
o.PartNo,
o.JobNo,
ord.DateEnt as oDateEnt,
por.MAXPONum,
po.DateEnt as poDateEnt,
tt.MAXtt,

CASE

Your sub query needs to be a LEFT JOIN instead of a regular JOIN which will allow it to include results if present and NULL otherwise.
--***SUB QUERY (Receiver)
LEFT JOIN
(
SELECT
MAX(cast(r.ReceiveDate as DATE)) as ReceiveDate,
por.JobNo
FROM
POReleases as por
INNER JOIN
Receiver as r on por.PONum = r.PONum
GROUP BY por.JobNo
) r
ON r.JobNo = o.JobNo
