SQL SUM columns only if they have different IDs

Hi there,

I am having some issues with my SQL query which is slightly complicated with many columns.
Below, I am providing a strip down version to show the exact problem.

I have the following table:


LogID|Type|Duration|Line
10052|IN  |13.0    |300|
10052|IN  |13.0    |300|
10052|IN  |11.0    |300|
10053|EX  |2.0     |300|
10053|IN  |6.0     |300|
10053|IN  |16.0    |300|
10053|OB  |13.0    |300|

I am doing the following query to find the total IN and Duration.


SELECT Line, SUM(CASE WHEN Type='IN'  THEN 1 ELSE 0 END) AS TotalInbound, SUM(CASE WHEN Type='IN' THEN Duration ELSE 0 END) AS TotalInboundDuration FROM TABLE WHERE Line <> '0000' AND Line <> '' GROUP BY Line;

This results in 300| 5| 59


However, I only wanted to count the IN's if they have different LogID.  So, here I want to get

300 | 2 | 59 as the result.

How can I fix it.  Thank you.

This would be my attempt:

SELECT Line, SUM(CASE WHEN t1.Type='IN'  THEN 1 ELSE 0 END) AS TotalInbound, SUM(CASE WHEN t1.Type='IN' THEN t1.Duration ELSE 0 END) AS TotalInboundDuration FROM 
table t1
WHERE t1.Line <> '0000' AND t1.Line <> '' 
and exists(select logid from table where line = t1.line and logid != t2.logid)
GROUP BY Line;

The other way to do it would be to fine all of the lines with differing log ids first, and then join on that:

select distinct t1.line 
into #lines
from
table t1 join 
table t2 on t1.line = t2.line and t1.logId != t2.LogID

Open in new window

and then your query would add in the where:

and t1.line in (select line from #lines)

You can also try this
SELECT Line, COUNT(1) TotalInbound, SUM(Duration) TotalInboundDuration
FROM (
	SELECT LogID, Line, SUM(Duration) Duration
	FROM YOUR_TABLE
	WHERE Type = 'IN'
	GROUP BY LogID, Line
) A
GROUP BY Line
