How to merge sql query with union into one query - sql

Question

I would like to get the results of the below query with just one query not by using union.
My query is as below
I am generating a SSRS chart this query, so need to merge the query into one and get a proper result as shown in table 2
select
res.Count, res.Month, res.status, res.SortOrder
from
(SELECT
count(analysis_complete_date) as Count,
DATENAME(month, analysis_complete_date) AS Month,
DATEPART(month, analysis_complete_date) AS SortOrder,
'Analysis' as status
FROM
SCN_Part_Details AS parts
WHERE
analysis_complete_date BETWEEN '2014-01-01' AND '2014-12-11'
GROUP BY
DATENAME(month, analysis_complete_date),
DATEPART(month, analysis_complete_date)
union
SELECT
count(Act_Supp_Negotiation_Date) as Count,
DATENAME(month, Act_Supp_Negotiation_Date) AS Month,
DATEPART(month, Act_Supp_Negotiation_Date) AS SortOrder,
'Negotiated' as status
FROM
SCN_Part_Details AS parts
WHERE
Act_Supp_Negotiation_Date BETWEEN '2014-01-01' AND '2014-12-11'
GROUP BY
DATENAME(month, Act_Supp_Negotiation_Date),
DATEPART(month, Act_Supp_Negotiation_Date) ) as res
order by
res.SortOrder
This will give a result like:
Table 1
Count Month Status SortOrder
--------------------------------------------------
167 January Analysis 1
631 January Negotiated 1
70 February Analysis 2
237 February Negotiated 2
and so on..
I want a result like this:
Table 2
AnalysisCount NegotiatedCount Month SortOrder
---------------------------------------------------------
167 631 January 1
70 237 February 2

Give it a try:
;WITH CTEResult AS
(
select
res.Count, res.Month, res.status, res.SortOrder
from
(SELECT
count(analysis_complete_date) as Count,
DATENAME(month, analysis_complete_date) AS Month,
DATEPART(month, analysis_complete_date) AS SortOrder,
'Analysis' as status
FROM
SCN_Part_Details AS parts
WHERE
analysis_complete_date BETWEEN '2014-01-01' AND '2014-12-11'
GROUP BY
DATENAME(month, analysis_complete_date),
DATEPART(month, analysis_complete_date)
union
SELECT
count(Act_Supp_Negotiation_Date) as Count,
DATENAME(month, Act_Supp_Negotiation_Date) AS Month,
DATEPART(month, Act_Supp_Negotiation_Date) AS SortOrder,
'Negotiated' as status
FROM
SCN_Part_Details AS parts
WHERE
Act_Supp_Negotiation_Date BETWEEN '2014-01-01' AND '2014-12-11'
GROUP BY
DATENAME(month, Act_Supp_Negotiation_Date),
DATEPART(month, Act_Supp_Negotiation_Date) ) as res
)
SELECT DISTINCT
(SELECT TOP 1 Count FROM CTEResult A WHERE A.Month = C.Month AND A.STATUS = 'Analysis' AND A.SortOrder = C.SortOrder) AS AnalysisCount,
(SELECT TOP 1 Count FROM CTEResult B WHERE B.Month = C.Month AND B.STATUS = 'Negotiated' AND B.SortOrder = C.SortOrder) AS
NegotiatedCount, C.Month, C.SortOrder
FROM CTEResult C

Answer 2

Once you got your result, you can pivot the table to get the desired result.
create table #temp
(
quantity int,
month varchar(20),
status varchar(20),
sortorder int
)
insert into #temp values
(167,'January' ,'Analysis', 1 ),
(631,'January' ,'Negotiated',1 ),
(70 ,'February','Analysis', 2 ),
(237,'February','Negotiated', 2 )
select max(analysis) as analysiscount
,max(negotiated) as negotiatedcount
,month
,max(sortorder) as sortorder
from
(
select *
from #temp
pivot
(max(quantity) for status in ([analysis],[negotiated])) as pi
) t
group by month
order by sortorder;
