Compare results of two selects statements - sql

Question

How can i compare the results of two select statements in TSQL (2014)?
my both queries:
SELECT CallDisposition, count(CallDisposition) as Count
FROM [bs_Reporting].[dbo].[Termination_Call_Detail]
where (DateTime between dateadd(minute,#timespan,convert(datetime2,(GETDATE())+ #count)) AND convert(datetime2,(GETDATE())+ #count))
Group by CallDisposition
SELECT CallDisposition, count(CallDisposition) as Count
FROM [bs_Reporting].[dbo].[Termination_Call_Detail]
where DateTime >= dateadd(minute,#timespan,convert(datetime2,(GETDATE())))
Group by CallDisposition
Results of Query 1:
+-----------------+-------+
| CallDisposition | Count |
+-----------------+-------+
| 2 | 2 |
| 3 | 8 |
| 4 | 8 |
| 7 | 21 |
| 10 | 16 |
| 13 | 738 |
| 14 | 45 |
| 15 | 14 |
| 19 | 8 |
| 28 | 41 |
| 29 | 12 |
| 52 | 76 |
| 55 | 1 |
+-----------------+-------+
Results of Query 2:
+-----------------+-------+
| CallDisposition | Count |
+-----------------+-------+
| 2 | 4 |
| 3 | 7 |
| 4 | 6 |
| 6 | 2 |
| 7 | 22 |
| 10 | 6 |
| 13 | 703 |
| 14 | 67 |
| 15 | 11 |
| 19 | 4 |
| 26 | 1 |
| 28 | 62 |
| 29 | 10 |
| 52 | 79 |
+-----------------+-------+
The main problem behind, the results of both queries can be different.
Based on example above: CallDisposition 6 and 26 are missing in Query 1.
CallDispoition 55 is missing in Query 2
Note: CallDispoition values 0-100 can be expected, maybe that helps?!
The expected result should look like that:
+-----------------+-------+
| CallDisposition | Count |
+-----------------+-------+
| 2 | 2 |
| 3 | 1 |
| 4 | 2 |
| 6 | 2 |
| 7 | 1 |
| 10 | 10 |
| .. | |
| .. | |
| .. | |
| 52 | 3 |
| 55 | 1 |
+-----------------+-------+

Answer 1

WITH S1 AS (SELECT CallDisposition, count(CallDisposition) as Count
FROM [bs_Reporting].[dbo].[Termination_Call_Detail]
where (DateTime between dateadd(minute,#timespan,convert(datetime2,(GETDATE())+ #count)) AND convert(datetime2,(GETDATE())+ #count))
Group by CallDisposition
)
,S2 AS (
SELECT CallDisposition, count(CallDisposition) as Count
FROM [bs_Reporting].[dbo].[Termination_Call_Detail]
where DateTime >= dateadd(minute,#timespan,convert(datetime2,(GETDATE())))
Group by CallDisposition
)
Select ISNULL(S1.CallDisposition,S2.CallDisposition) AS CallDisposition
,ABS(ISNULL(S1.COUNT,0)-ISNULL(S2.Count,0)) Count
FROM S1 FULL JOIN S2
ON S1.CallDisposition=s2.CallDisposition

Answer 2

Honestly I'm puzzled by your expected result and that compares the results. So my solution won't produce such a result. But maybe it helps by pointing you tte right direction.
You can to full join the results on calldisposition. That way coexisting calldisposition will be put next to each other. If for a calldisposition in one result no one exists in the other the columns of the other will be all NULL.
SELECT *
FROM (SELECT calldisposition,
count(CallDisposition) count
FROM [bs_Reporting].[dbo].[Termination_Call_Detail]
WHERE (datetime BETWEEN dateadd(minute, #timespan, convert(datetime2, (getdate()) + #count))
AND convert(datetime2, (getdate()) + #count))
GROUP BY calldisposition) x
FULL JOIN (SELECT calldisposition,
count(calldisposition) count
FROM [bs_Reporting].[dbo].[Termination_Call_Detail]
WHERE datetime >= dateadd(minute, #timespan, convert(datetime2, (getdate())))
GROUP BY calldisposition) y
ON y.calldisposition = x.calldisposition;

Answer 3

I'd probably insert the results into a temporary table, then query that. Use a table variable:
DECLARE #Results TABLE ([Source] VARCHAR(10), CallDisposition INT, [CallCount] INT)
(Use CallCount as that's not a reserved word)
INSERT INTO #Results(CallDisposition , CallCount, [Source])
SELECT CallDisposition, count(CallDisposition) as Count, [Source] = 'Query1',
FROM [bs_Reporting].[dbo].[Termination_Call_Detail]
where (DateTime between dateadd(minute,#timespan,convert(datetime2,(GETDATE())+ #count)) AND convert(datetime2,(GETDATE())+ #count))
Group by CallDisposition
Repeat with your 2nd query, Setting Source = 'Query2' (or union with it in the above insert).
Now you can examine your #Results:
SELECT r1.* FROM #Results r1
WHERE [Source] = 'Query1'
AND NOT EXISTS (SELECT 'X' FROM #Results r2 WHERE [Source] = 'Query2' AND r2.CallDisposition = r1.CallDisposition)
(example only; possibly not the most insightful)
Please forgive any slight syntax errors; I don't have SQL Server in front of me.
