extend SQL result - add row if not exist - sql

Question

At the moment I have a query like this:
SELECT d.[status]
,d.[PGID] as PGID
,pg.[nvarchar5] as PGName
,COUNT(d.[nvarchar10])
FROM
[content].[dbo].[USRData] d
INNER JOIN
[content].[dbo].[USRData] pg on d.[PGID] = pg.[tp_ID]
WHERE d.CatId = '12345'
AND d.[nvarchar10] is not null
AND d.[isActive] = 1
AND pg.[CatId] = '64521'
GROUP BY
pg.[nvarchar5]
,d.[status]
ORDER BY PGName
This is the result (just a fictive example):
status PGID PGName Total
--------- ------- --------- ---------
active 10 HR 120
deleted 10 HR 5
new 10 HR 10
active 15 IT 10
new 15 IT 40
deleted 32 FI 12
new 32 FI 30
I need a query so the result should be like this:
status PGID PGName Total
--------- ------- --------- ---------
active 10 HR 120
deleted 10 HR 5
new 10 HR 10
active 15 IT 10
deleted 15 IT 0
new 15 IT 40
active 32 FI 0
deleted 32 FI 12
new 32 FI 30
The difference is: I want for every PG a list of total for every possible status, even if it doesn't exist. If it doesn't exist I need a row like for example "deleted 15 IT 0"
I need to now every total of a possible status for every PG.
What do I need to change?
Edit:
More information
In the current query the inner join is on PGID and not status
about my table, an example: use array/variable in sql-query
Update 2:
with this query I get better results, only the total is not correct...
SELECT stat.status
,d.[PGID] as PGID
,pg.[nvarchar5] as PGName
,COUNT(d.[nvarchar10])
FROM
(select distinct [status]
from [content].[dbo].[USRData]
where CatId = '1234') stat cross Join
[content].[dbo].[USRData] d INNER JOIN
[content].[dbo].[USRData] pg on d.[PGID] = pg.[tp_ID]
where d.CatId = '1234'
AND d.[nvarchar10] is not null
AND stat.status is not null
AND d.[isActive] = 1
AND pg.[CatId] = '64521'
group by stat.status,
pg.[nvarchar5],
d.[PGID]
order by PGName
With my example as above, this is what I get:
status PGID PGName Total
--------- ------- --------- ---------
active 10 HR 135
deleted 10 HR 135
new 10 HR 135
active 15 IT 50
deleted 15 IT 50
new 15 IT 50
active 32 FI 42
deleted 32 FI 42
new 32 FI 42
I get the total for every PGName. How can I get the total for every PGName/status?

Answer 1

You do this by creating the cartesian product of status and PGID. You can get this from the table your are using. In this case, I think the query is:
SELECT sall.[status], pgall.[PGID] as PGID, pg.[nvarchar5] as PGName, COUNT(d.[nvarchar10])
FROM (select distinct status from [content].[dbo].[USRData]) sall cross join
(select distinct pgid from [content].[dbo].[USRData]) pgall left outer join
[content].[dbo].[USRData] d
on d.status = sall.status left outer join
[content].[dbo].[USRData] pg
on pg.[PGID] = pgall.[tp_ID]
where d.CatId = '12345' AND
d.[nvarchar10] is not null AND
d.[isActive] = 1 AND
pg.[CatId] = '64521'
group by pgall.[nvarchar5], sall.[status]
order by PGName
I'm not 100% sure this is what you want, because you are taking PGID and status from the d table -- I don't fully understand the self join here.

Answer 2

Inner Join is issue in you query, it excludes Roles who don't have users, instead use Left join
SELECT d.[status]
,d.[PGID] as PGID
,pg.[nvarchar5] as PGName
,COUNT(d.[nvarchar10])
FROM [content].[dbo].[USRData] d Left JOIN
[content].[dbo].[USRData] pg on d.[PGID] = pg.[tp_ID]
where d.CatId = '12345'
AND d.[nvarchar10] is not null
AND d.[isActive] = 1
AND pg.[CatId] = '64521'
group by pg.[nvarchar5], d.[status]
order by PGName
