SELECT Value even if NULL on LEFT JOIN - tsql

Question

I am trying to pull data out and chuck it into a Stimulsoft report. The problem I am having is that I need it to output to two columns. I also need every "manager" record to show even if the count assigned to said record is NULL.
This is what i have at the moment:
DECLARE #ManagerCount INT = (( SELECT Count(*) FROM AM WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0 ) + 1) / 2
DECLARE #tmp_AM1 TABLE (AMID INT, AMName NVARCHAR(100), ID INT)
INSERT INTO #tmp_AM1 SELECT AMID, AMName, row_number() over (order by AMID ) FROM AM
WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0
SELECT * FROM (
SELECT ta.id AS id1, ta.AMName AS ManagerName1, COUNT(*) AS ManagerCount1 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID BETWEEN 1 AND #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.ID, ta.AMName
) a
LEFT JOIN
(
SELECT ta.id AS id2,ta.AMName AS ManagerName2, COUNT(*) AS ManagerCount2 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID > #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.AMName, ta.ID
) b ON a.id1 + #ManagerCount = b.id2
Which ends up returning something like:
There are 18 managers so 9 per column, but this code doesn't show them all since anything that doesn't have a count in the first left join, won't show, and therefore the same row in column 2 doesn't show.

DECLARE #tmp_AM1 TABLE (AMID INT, AMName NVARCHAR(100), ID INT)
INSERT INTO #tmp_AM1 SELECT AMID, AMName, row_number() over (order by AMID ) FROM AM
WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0
SELECT * FROM (
SELECT ta.id AS id1, ta.AMName AS ManagerName1, COUNT(*) AS ManagerCount1 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID BETWEEN 1 AND #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.ID, ta.AMName
) a
LEFT OUTER JOIN
(
SELECT ta.id AS id2,ta.AMName AS ManagerName2, COUNT(*) AS ManagerCount2 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID > #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.AMName, ta.ID
) b ON a.id1 + #ManagerCount = b.id2 where ManagerName2 IS Null and ManagerCount2 IS NULL
just you want to use LEFT OUTER JOIN for select row even there is have any null values.,

Since the two subqueries are pretty much identical, except the where-statement, I would consiter rewriting it into one single query. I'm not sure why you need the same columns outputed into different columns in the result, but something like this might work:
WITH cte AS (
SELECT
ta.id AS id
,ta.AMName AS ManagerName
,COUNT(*) AS ManagerCount
,CASE WHEN ta.ID BETWEEN 1 AND #ManagerCount THEN 0 ELSE 1 END AS something
FROM
#tmp_AM1 tA
INNER JOIN Job J ON tA.AMID = j.AMID
WHERE
j.jobStatusID != 5
GROUP BY
ta.ID
,ta.AMName
,CASE WHEN ta.ID BETWEEN 1 AND #ManagerCount THEN 0 ELSE 1 END
)
SELECT
CASE WHEN something = 0 THEN cte.id ELSE null END AS id1
,CASE WHEN something = 0 THEN cte.ManagerName ELSE null END AS ManagerName1
,CASE WHEN something = 0 THEN cte.ManagerCount ELSE null END AS ManagerCount1
,CASE WHEN something = 1 THEN cte.id ELSE null END AS id2
,CASE WHEN something = 1 THEN cte.ManagerName ELSE null END AS ManagerName2
,CASE WHEN something = 1 THEN cte.ManagerCount ELSE null END AS ManagerCount2
FROM
cte

Probably not the best approach but i got the correct output using:
DECLARE #ManagerCount INT = (( SELECT Count(*) FROM AM WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0 ) + 1) / 2
DECLARE #tmp_AM1 TABLE (AMID INT, AMName NVARCHAR(100), ID INT)
INSERT INTO #tmp_AM1 SELECT AMID, AMName, row_number() over (order by AMID ) FROM AM
WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0
ORDER By AMName
SELECT ManagerName1, ManagerName2, ManagerCount1, ManagerCount2 FROM (
SELECT AMID, ta.id AS id1, ta.AMName AS ManagerName1 FROM #tmp_AM1 tA
WHERE (ta.ID BETWEEN 1 AND #ManagerCount)
) a
LEFT JOIN
(
SELECT AMID, ISNULL(COUNT(*), 0) AS ManagerCount1 FROM Job j
INNER JOIN tblJobOutcome jO ON j.JobOutcomeID = jo.JobOutcomeID AND jO.JobOutcomeID != 5
GROUP BY AMID
) a1 ON a.AMID = a1.AMID
LEFT JOIN
(
SELECT AMID, ta.id AS id2, ta.AMName AS ManagerName2 FROM #tmp_AM1 tA
WHERE (ta.ID > #ManagerCount)
) b ON a.id1 + #ManagerCount = b.id2
LEFT JOIN
(
SELECT AMID, ISNULL(COUNT(*), 0) AS ManagerCount2 FROM Job j
INNER JOIN tblJobOutcome jO ON j.JobOutcomeID = jo.JobOutcomeID AND jO.JobOutcomeID != 5
GROUP BY AMID
) b1 ON b.AMID = b1.AMID
Gives me the correct output in two columns.
gives me this:
