Divide results of two queries and obtain result in third query - sql-server

Question

I have two SQL queries that I want to divide. On their own each query works, and I want to divide their results and obtain into third variable, but I am unsure how.
This query calculate no of cancelled members
(select count(*) as No_of_Member_Cancelled, M.HomeBranch,M.LocationName from
AX.Memberships M
where M.ActiveEnd between DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) - 1,
0) and DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) ,-1)
group by M.HomeBranch,M.LocationName) as g1
This query calculate the no of live members
(select count(*)as No_of_Live_Member , M.HomeBranch,M.LocationName
from AX.Memberships M
where M.ActiveStart between DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) -
1, 0) and DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) ,-1)
group by M.HomeBranch,M.LocationName) as g2
We obtain results like this
if x = g1/g2
x , LocationName , HomeBranch in one table

Answer 1

Best to change those to temp tables then you can do it like this:
select No_of_Member_Cancelled / No_of_Live_Member as x, HomeBranch, LocationName
from G1
join G2 on g1.HomeBranch = g2.HomeBranch and g1.LocationName = g2.LocationName
group by HomeBranch, LocationName

Answer 2

Try this...
SELECT CAST (g1.no_of_member_cancelled AS DECIMAL(10, 2)) /
CAST (g2.no_of_live_member AS DECIMAL(10, 2)) AS x,
g1.homebranch,
g1.locationname
FROM (SELECT Count(*) AS No_of_Member_Cancelled,
M.homebranch,
M.locationname
FROM ax.memberships M
WHERE M.activeend BETWEEN Dateadd(month, Datediff(month, 0, Getdate())
- 1, 0)
AND
Dateadd(month, Datediff(month, 0,
Getdate())
, -1)
GROUP BY M.homebranch,
M.locationname) AS g1
INNER JOIN (SELECT Count(*)AS No_of_Live_Member,
M.homebranch,
M.locationname
FROM ax.memberships M
WHERE M.activestart BETWEEN Dateadd(month, Datediff(month, 0
,
Getdate()) - 1,
0) AND
Dateadd(month, Datediff(month,
0, Getdate(
)), -1)
GROUP BY M.homebranch,
M.locationname) AS g2
ON g1.homebranch = g2.homebranch
AND g1.locationname = g2.locationname
You will need to cast (or convert) your number of cancelled and live members to the datatype that fits your situation given the size of your potential values. You probably should take precaution so you don't get a division by zero error.

Answer 3

SELECT distinct CAST (g1.no_of_member_cancelled AS DECIMAL(10, 2)) /
CAST (g2.no_of_live_member AS DECIMAL(10, 2)) AS x,
g1.homebranch,
g1.locationname,
g1.month,
g1.year
FROM (SELECT Count(*) AS No_of_Member_Cancelled,
M.homebranch,
M.locationname,
month(M.ActiveStart) month,
YEAR(M.ActiveStart) year
FROM ax.memberships M
WHERE M.activeend BETWEEN Dateadd(year, Datediff(year, 0, Getdate()) - 2, 0)
AND
Dateadd(year, Datediff(year, 0, Getdate()), -1)
GROUP BY M.homebranch,
M.locationname,month(M.ActiveStart),
year(M.ActiveStart)) AS g1
INNER JOIN (SELECT Count(*)AS No_of_Live_Member,
M.homebranch,
M.locationname,
month(M.ActiveStart) month,
YEAR(M.ActiveStart) year
FROM ax.memberships M
WHERE M.activestart BETWEEN Dateadd(year, Datediff(year, 0, Getdate()) - 2, 0)
AND
Dateadd(year, Datediff(year, 0, Getdate()), -1)
GROUP BY M.homebranch,
M.locationname,
month(M.ActiveStart),
year(M.ActiveStart)
) AS g2
ON g1.homebranch = g2.homebranch
AND g1.locationname = g2.locationname
AND g1.month = g2.month
AND g1.year = g2.year
Order by g1.year,g1.month
Can you please check my query is right or not. Because I wanted to get from last 2 yrs.
