Description:
Need an SQL Query for an ASP page using MS SQL Server 2000. There is a table called Precipitation_Data with the fields Date/Time, [Sensor ID], [Data Value], and [Data Type] The query must return the SUM of the [Data Value] for each "day" (day meaning from 8:00AM to 8:00AM) and then return the DATE of that SUM so for example there were 3 records on a Monday (ranging from 4pm to 10pm) that the [Data Value] totaled 4.5 and there were 10 records on Tuesday that the [Data Value] totaled 9 and on Tuesday there were 2 records that the [Data Value] totaled 1.3 I would get a record set that had DATE DD/MM/YYYY(This would be from 8:00AM That day to 8:00 the NEXT day) then the SUM value for that DATE. I.E
02/03/2003 4.5 (next record) 02/04/2003 9 (then next record) 02/05/2003 1.3 The variables that will change is the BETWEEN Dates. Here is an SQL stmt that I have been modifying but it will give you an idea of the varibles: sql="SELECT Min([Data Value]) as MIN, [Date/Time] FROM [Precipitation_Data] WHERE [Sensor ID] = '" & sensorid & "' and [Data Type] = 'S' GROUP BY [Date/Time] HAVING [Date/Time] BETWEEN'" & datestart & "'AND'" & dateend & "' ORDER BY [Date/Time]" The other SQL quries will be a variation of the one we need and will be SUMMING the Weeks, then Months, then Years

Since your project is required to be completed ASAP, I paste my tested SQL directly without my bidding accepted by you.
SQL:
SELECT Sum([Data Value]) as Data_Value,
( Right(('00' + Cast(Month(DateAdd(hh,-8,[Date/Time])) as varchar(2))),2) + '/' + Right(('00' + Cast(Day(DateAdd(hh,-8,[Date/Time])) as varchar(2))),2) + '/' + Cast(Year(DateAdd(hh,-8,[Date/Time])) as varchar(4) ) ) as Date_Time
FROM [Precipitation_Data]
WHERE [Sensor ID] = '123' and [Data Type] = 'S' and
[Date/Time] > '02/03/2003 08:00:00' and [Date/Time] < '02/06/2003 08:01:00'
GROUP BY ( Right(('00' + Cast(Month(DateAdd(hh,-8,[Date/Time])) as varchar(2))),2) + '/' + Right(('00' + Cast(Day(DateAdd(hh,-8,[Date/Time])) as varchar(2))),2) + '/' + Cast(Year(DateAdd(hh,-8,[Date/Time])) as varchar(4) ) )
ORDER BY ( Right(('00' + Cast(Month(DateAdd(hh,-8,[Date/Time])) as varchar(2))),2) + '/' + Right(('00' + Cast(Day(DateAdd(hh,-8,[Date/Time])) as varchar(2))),2) + '/' + Cast(Year(DateAdd(hh,-8,[Date/Time])) as varchar(4) ) )
My testing data:
Date/Time Sensor ID Data Value Data Type
2003-2-4 8:21:00 123 1 S
2003-2-4 10:01:00 123 1 S
2003-2-4 11:01:00 123 1 S
2003-2-4 13:01:00 123 1 S
2003-2-4 14:01:00 123 1 S
2003-2-4 15:01:00 123 .5 S
2003-2-4 18:01:00 123 1 S
2003-2-5 7:59:00 123 1 S
2003-2-3 16:00:00 123 1 S
2003-2-3 18:00:00 123 1 S
2003-2-3 22:00:00 123 2.5 S
2003-2-4 8:01:00 123 1 S
2003-2-4 12:01:00 123 .5 S
2003-2-5 10:00:00 123 .6 S
2003-2-6 3:00:00 123 .7 S
2003-2-3 4:00:00 123 .8 S
And the result:
4.5 02/03/2003
9.0 02/04/2003
1.3 02/05/2003
If my bid price is higher than other's, please let me know. I can decrease it accordingly. Or I can develop the other sql statements for you for free.
