Thanks for reading 😀
Im trying to create a view, and im having trouble doing one function. I have a table with the following
ID timestamp value
1, 04/07/2013 00:00:00, 10
1, 04/07/2013 00:30:00, 11
2, 04/07/2013 00:00:00, 11
2, 04/07/2013 00:30:00, 11
I need the following
ID Count value
1, 2, 21
2, 2, 22
I using the below to get my results when the table only has one month range.
SELECT ID, COUNT(TimeStamp) AS Count, SUM(Vale) AS Value
FROM mytable
GROUP BY ID
Where (ID = '1') OR
(ID = '2') OR
But now i need to add multiple months, and im struggling. Any help would be greatly appreciated.

This would be sufficient:
SELECT ID, COUNT(TimeStamp) AS Count, SUM(Vale) AS Value
FROM mytable
GROUP BY ID
There's no need for a WHERE clause. By the way, not a very effective ID if it has duplicates.

Oh im a idiot :doze:
Amend my previous.
SELECT MeterID, COUNT(TimeStamp) AS Count, SUM(WattHours) AS WattHours
FROM dbo.NewvMData
GROUP BY MeterID
HAVING (MeterID = '203201582') OR
(MeterID = '203201588') OR
As i have Meters in the table i dont wish results returned. Previously i only have one months data in the table, now i have three.
so the previous results were
203201582 1440137497219.28343752
203201588 144018056670.550566405
204001454 1440919623.39525939862
Where as now im looking to return the Months totals seperate,
203201582 1440137497219.28343752 01/06/2013
203201588 144018056670.550566405 01/06/2013
204001454 1440919623.39525939862 01/06/2013
203201582 1440137497219.28343752 01/05/2013
203201588 144018056670.550566405 01/05/2013
204001454 1440919623.39525939862 01/05/2013
My previous view would total all the months and return the count with three times the amount.
Thank you for you reply, sorry about not being totally correct with my first post.

Simply add the month column in the GROUP BY clause.
By the way, using HAVING on a column on which you group - thus not an aggregate - is the same as using WHERE.

Thank you for your response 😀
I tried Adding the Month to the Group by, and now its returning
Meter ID Count Watthours
203201582 155226.30078125
203201582 155330.86328125
203201582 152783.71484375
203201582 153696.5625
203201582 153230.19140625
203201582 154420.70703125
The data im querying looks like
MeterID TimeStamp WattHours
203201582 5/05/2013 12:00:00 AM57736.625
203201582 5/05/2013 12:30:00 AM57014.62890625
203201582 5/05/2013 1:00:00 AM56760.8828125
203201582 5/05/2013 1:30:00 AM56346.12109375
203201582 5/05/2013 2:00:00 AM58058.109375
203201582 5/05/2013 2:30:00 AM57952.47265625
I would like to return
Meter, Count, Watthours , Month
203201582, 1440,137497219.28343752, JUN
So instead of counting the totaly halfhour trends and return the total count and then summing the watthours for the month, its just returning the count as i 1440 times. I need the query to return a extra colum.
Thank you for your responses 😀

How do you calculate the 1440?

each meter report watthours every 30mins, so in a 30 day month there are 1440 entries. 😀
So i Count the TimeStamp colum to get 1440.
Sorry i did a really bad job at posting my question, im new to this 😀

OK, so just add COUNT(Timestamp) to your query.

OK, it seems i must have confused the whole thing. I managed to just solve it
SELECT MeterID, COUNT(TimeStamp) AS Count, SUM(WattHours) AS WattHours, MONTH(TimeStamp) AS Month
FROM BillingHistoryvMData
GROUP BY MeterID, MONTH(TimeStamp)
As i wanted to count the timestamp column by month and them sum the months watthours.
Not been one of the best weeks regarding concentration, pregnant partner.
Sorry and thank you

No need to apologize. 🙂
Wait until after the birth, then things start to get hectic. 🙂
