Hi!

First thanks for the help I got a couple of weeks ago!

Now to my new proble that is to change this statement a bit as it works halfway...

SELECT *, ISNULL(Denmark,0) + ISNULL(Finland,0) + ISNULL(Lithuania,0) + ISNULL(Norway,0) + ISNULL(Sweden,0)
AS Total
FROM
(SELECT DropRate,MarketingName, Manufacturer, Country
FROM ReportedNetInfoData) s PIVOT (SUM(DropRate)
FOR Country IN ([Denmark], [Finland], [Lithuania], [Norway], [Sweden]))P

The simplified table looks like this:

DropRate Country MarketingName Manufacturer
0.000000000000 Denmark Zoarmon Intel
0.000000000000 Denmark USB316 Sierra Wireless
0.000000000000 Denmark XP3300-AR1 (P25C005AA) Sonim
0.000000000000 Denmark 700C Intermec Technologies Corp.
4.762000000000 Denmark R6230GE BlackBerry
0.000000000000 Denmark SGH-S300 Samsung
0.000000000000 Denmark Treo 600 Palm

The result from the sql-statement is something like this:
(the null values under all countries except denmark depends on no data from them yet)

MarketingName Manufacturer Denmark Finland Lithuania Norway Sweden Total
5130 XpressMusic Nokia 153.725000000000 NULL NULL NULL NULL 153.725000000000
3310 Nokia 151.236000000000 NULL NULL NULL NULL 151.236000000000
1100 Nokia 151.206000000000 NULL NULL NULL NULL 151.206000000000
iPhone 4 Apple 144.371000000000 NULL NULL NULL NULL 144.371000000000
1208 Nokia 133.742000000000 NULL NULL NULL NULL 133.742000000000
iPhone 4S Apple 130.181000000000 NULL NULL NULL NULL 130.181000000000
X1-01 Nokia 129.931000000000 NULL NULL NULL NULL 129.931000000000
SGH-E250 Samsung 118.778000000000 NULL NULL NULL NULL 118.778000000000
6300 Nokia 112.905000000000 NULL NULL NULL NULL 112.905000000000
101, 1010 Nokia 110.319000000000 NULL NULL NULL NULL 110.319000000000

This is fine. I have the total drop rate however I am also looking for the average drop rate per country as well as the average drop rate for the total. (Total rate / # of countries per model)

Ie. IPhone 4 occurs Three times with droprate 1 an 2 and 3 for sweden and 2 and 4 and 6 for Norway then it should produce the average 2 for sweden and 4 for norway and total should be showing (countries + countries) divided by number of countries like (2+4)/2 in this case because it shouldn´t divide by countries that return null values when summaring and Dividing the total.

Hope I didn+t confuse you to much!

Thank´s in advance // TT

do you mean this?


SELECT *, ISNULL(Denmark,0) + ISNULL(Finland,0) + ISNULL(Lithuania,0) + ISNULL(Norway,0) + ISNULL(Sweden,0) 
AS Total 
FROM 
(SELECT DropRate,MarketingName, Manufacturer, Country ,AVG(DropRate)OVER (PARTITION BY Country) AS CntAvg
FROM ReportedNetInfoData) s PIVOT (SUM(DropRate) 
FOR Country IN ([Denmark], [Finland], [Lithuania], [Norway], [Sweden]))P

Hivisakh16!

Not exaktly but that gave me some idéeas for the future :-)
Maybe my new explanation is a Little bit clearer!

Okey!
I have come a bit further on the way to a solution and have included a script for creating a test-table with sample dummy data in it!

The result from the sql-statement now works fine except the total sum result that has to be divided by the number of columns that do not return null values or is greater then zero so in this case with the sample data it should be divided by 3 but how do I solve that?

Sql statement:

SELECT *, ISNULL(Denmark,0) + ISNULL(Finland,0) + ISNULL(Lithuania,0) + ISNULL(Norway,0) + ISNULL(Sweden,0) AS Total
FROM (SELECT DropRate,MarketingName, Manufacturer, Country FROM tblTest) s PIVOT (AVG(DropRate)
FOR Country IN ([Denmark], [Finland], [Lithuania], [Norway], [Sweden]))P

Generates output:
MarketingName Manufacturer Denmark Finland Lithuania Norway Sweden Total
iPhone 3G Apple 1.408000000000 1.485000000000 0.000000000000 NULL 2.625000000000 5.518000000000

What I need is:
Should be: (difference is the division by three in this example)

SELECT *, (ISNULL(Denmark,0) + ISNULL(Finland,0) + ISNULL(Lithuania,0) + ISNULL(Norway,0) + ISNULL(Sweden,0)) / 3 AS Total
FROM (SELECT DropRate,MarketingName, Manufacturer, Country FROM tblTest) s PIVOT (AVG(DropRate)
FOR Country IN ([Denmark], [Finland], [Lithuania], [Norway], [Sweden]))P

That generates output:
MarketingName Manufacturer Denmark Finland Lithuania Norway Sweden Total
iPhone 3G Apple 1.408000000000 1.485000000000 0.000000000000 NULL 2.625000000000 1.839333333333

But from time over time the amount of null or zero values in the columns will differ so I need intelligence in the sql-statement that takes care of this and this is above my knowledge for the moment :-(

And of course this is very simplified and I have my reason to include a country that is not represented in the sample data and so on ;-)

Here you go with the sample table.

GO

[code]

Great!
That solved my problem and you made my day visakh16 ! :-)

As I´m building the statement dynamically this was exactly what I was looking for!

Many thanks!

Tested your solution and it works like a charm,!

Thanks again // Thomas
