Im trying to get the average Fuel Consumption for A Manufacturer that produces two or more cars, so far ive only been able to find all manufacturers Average Fuel consumption.
Heres what I have so far
Select aManufacturer.MName, avg(FuelCons) From aCar Join aBuilts On aBuilts.CName = aCar.CName Join aManufacturer On aBuilts.MName = aManufacturer.MName Group by aManufacturer.MName
This produces nearly all I want only I need to be able to get only the Manufacturers who produce two or more Cars, ive tried implementing a few Count statements but nothings working, any ideas?
I need to calculate average of each student and then get the highest.
My try:
Code: SELECT Students.StudentId,Students.StudentName,AVG(Grades.Grade) AS avg_grade FROM Students s JOIN Grades g ON Grades.StudentId =Students.StudentId GROUP BY Students.StudentId, Students.StudentName
ORDER BY avg_grade LIMIT 1 FROM Students;
I encounter problem with this code, maybe it's Completely wrong...
I am having tables with 12 columns as jan,feb,.......dec.
Now I want to calculate average salary for each record, but condition is that if any month salary is zero then that column also exclude from average calculation.
For example : if jan and feb column values are zero then i want to calculate (mar+apr+...+dec)/10.
Eg: I have productivity records of each day and each employee. I need to calculate avg of each last level employee productivity by monthly. Again Last level employee productivity avg must be added up with their immediate head. But, when I define a Measure Item as avg in the cube, it sums all the values of lost level employees & head and divides with number of records (normal avg).
My requirement is calculating each head avg by sum of each last level employee avgs / no of employees. If head having value, he too will be added. Again Head’s Avg will be added up immediate head.
The following calculation gives average value at each level.
Average of Level 3(E4) = > (4+3+7+6)/4 = 5 hrs/day< = (E6+E7+E8+E4)/4
Average of Level 2(E2) = > (5+3+5)/3= 4.333 < =avg(Level3(E4))+avg(Level3(E5)))/2
Average of Level 1(E1) = > (4.333+4+1)/3 = 3.111 < = avg(Level3(E2))+avg(Level3(E3)))/2
Formula for average of level : : (Sum of Children value + Head Value of Corresponding children) / (No.of Children +1)
I want to calculate average of each employee as well as average of each level in cube (SQL Server Analysis Services).
Out of this table what I need to do is calculate the average value for each same [Name]. As you can see from the sample set above, the Diameter1 has 2 entries value hich gets store at different time of course.
So I I take the example of Diameter1 I need to calculate and display in a field the average results. The result would be
Name Average ===================== Diameter1 ..... Diameter2 .... Temperature2 .... Temperature1 ....
How can I perform this ?
Or could it be better to get a view of the table above which gets display as follow :
I am having trouble with calculating AVG in a matrix. I have done the subtotal but I would like to know how to calculate the Average. I would also like AVA below the Total.

I am trying to create a SSRS report that needs to show average for both parent and child rows. In the example below i need to show an average of ErrorRecAge column for Company, then for cic_Group and one grand total/avg. How can this be done from single query (as below) and using SSRS built in functions/codes? I am also curious to know if this can be done from TSQL directly (ex. something similar to running sum/total). I appreciate the help.
Select
CustomerCorrection.Id As ParentId,
cc_company As cc_company2,
ccError.Id As ErrorId,
COALESCE(cic_Group,'Other Errors') As cic_Group,
COALESCE(cic_Code,'Unknown') As ErrorCode,COALESCE(cic_Description,'Unknown') As ErrorDescription,
DateDiff(hh,cc_entrydt,getdate())/24.00 AS ErrorRecAge
How you would calculate the average read/write latency experienced by a SQL Server instance during a specific time window in order to monitor this for multiple instances. From this MSDN blog, I know that you have to take multiple samples and do some calculations to get the correct latency.

However, the SQLServer:Resource Pool Stats object tracks these numbers per resource pool and we want to get one number for the whole server. Since there can be a different base value for each resource pool, you can't simply sum the numerator values together. Here's some sample data from a server that illustrates the problem.
object_name counter_name instance_name cntr_value cntr_type SQLServer:Resource Pool Stats Avg Disk Read IO (ms) default 307318919 1073874176 SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base default 25546724 1073939712 SQLServer:Resource Pool Stats Avg Disk Read IO (ms) internal 2045730 1073874176 SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base internal 208270 1073939712
I'm thinking I would need to do some sort of weighted average, but I'm not sure if that will result in the correct value. Here's the formula I am thinking about using currently before doing the calculation over time
I have got this matrix and I am trying to calculate the average amount of working days in a month. At the moment, I have divided the total number of jobs by 21 for every month which is a hard coded value. However, I am not sure how to retrieve this value dynamically. Is there any formula that can find out the working days?
I'm wanting to get the average number of days between orders in my orders tbl - so I've done a search and found the following sql coded that I have modified for my db tbl's and columns. But when I try and parse it - I get 'Incorrect syntax new the keyword Group' - what am I missing.
SELECT custId, AVG(invDate - priorDate) FROM(SELECT custId,invDate,LAG(invDate) OVER (PARTITION BY custId ORDER BY invDate)as priorDate FROM orders) Group BY custId
What is the piece of SQL which looks at the average date difference for each enquiry and then sums it all up to give an overall average number of days it takes?
We are trying to get a rough estimate of the size of the warehouse in terms of number of bytes. Now I understand that when I say char(2) datatype requires 2 bytes of memory. If this is correct then how many bytes does the following data type need -
I am trying to find out the the Average number of contact hours per student. in Reporting Services 2005. The contact hours is the in the Totaltime field
Is this formula correct
=Sum(Fields!TotalTime.Value)/Avg(Fields!TotalTime.Value) is in the =Fields!StateServices.Value Group
Example table structure: Id int, PK Name varchar AddDate smalldatetime
Sample data: Id Name AddDate 1 John 01/15/2005 2 Jane 01/18/2005 . . . 101 Jack 01/10/2006 102 Mary 02/20/2006
First, I need to find the month which has the most records, I finally produced the correct results using this query but I am not convinced it's the most efficient way, can anyone offer a comment or advice here?
select top 1 count(id), datename(mm, AddDate) mth, datepart(yy, AddDate) yr from dbo.sampletable group by datename(mm, AddDate), datepart(yy, AddDate) order by count(id) desc
Also, I'm really having trouble trying to get the overall average of records per month. Can anyone suggest a query which will produce only one number as output?
I have this table of Marks as shown below. All I need is to find the average Marks at various intervals of S.no. That is I need averages at every 3rd S.No. as shown.
S.No. Marks 1 ------ 5 2 ------ 5 3 ------ 6 1st Average Value here (16/3) 4 ------ 5 5 ------ 6 6 ------ 7 2nd Average Value here (18/3) 7 ------ 7 8 ------ 7 9 ------ 8 3rd Average Value here (22/3) 10 ----- 8 11 ----- 9 12 ----- 8 4th Average Value here (26/3)
So basically I need a new table which will have 4 average values for the table above. Of-course the table can be much bigger and the average values can be at any nth value of S.No.
When viewing a report our users see that it is x number of pages, however when they print the report is actually y number of pages. For example once a report is ran, it says that it is 43 pages, however in actuality it is 62 pages. If they only want to print the last page, they choose to print 43 from the print dialog box, but that gives them a page in the middle of the report not the last page. Is there a way to remedy this?
I am trying to calculate the number of hours a device has been used and I cant find how. I need a query that calculated and does an average of the number of hrs used in a week.
I have got a huge table which contains patients data. I need to calculate the the no of patients for each clinical service.
Here is the sample data Patient no Startdate EndDate ClinicalService cost 1qq 12/04/03 15/04/03 restHome $12 2qq 1/1/07 1/2/07 dementia $4234.00 3ww 30/01/04 12/01/06 hospital $1244 1qq 1/1/2004 12/1/2004 dementia $400
Assumption: If a person has been in two services at a different period of time, he will be treated as a different case each time in every different service.
I have got a table of dates called 'static_tab' which contains all the possible dates. here is the script for the 'static_tab' table
USE [LOSDSS1] GO /****** Object: Table [dbo].[static_tab] Script Date: 11/13/2007 14:51:52 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[static_tab]( [cnt] [int] NULL, [dates] [datetime] NULL, [Quarter] [nvarchar](50) COLLATE Latin1_General_CI_AS NULL ) ON [PRIMARY]
I have been using a query for calculating total cost for each patient for each catagory . Its as follows
Select Year(x.dates) As [Year], Month (x.dates) As [Month],x.clinicalservice Sum(dailyvol) As cost
From c.dates,f.clinicalService, (f.cost / (DateDiff(dd, f.[Start date], f.[End date]) + 1)) As DailyVol From tablePatients f
Inner Join static_tab c On c.dates Between f.[Start date] And f.[End date]) as x Group By Year(x.dates), Month (x.dates),x.clinicalservice
Order By Year(x.dates), Month (x.dates),x.clinicalservice
And the output table is as follows clinical service Year Month cost Dementia 2007 7 1016842.852 Dementia 2007 8 1005945.664 Dementia 2007 9 976899.9008 Hospital Care 2003 10 2714517.879 Hospital Care 2003 11 2724111.029
I want the similar output but insteasd of cost, I need the patient count. I tried doing it but it gives me a conversion error
Calculation of an average using DAX' AVERAGE and AVERAGEX.This is the manual calculation in DW, using SQL.In the tabular project (we're i've noticed that these 4 %'s are in itself strange), in a 1st moment i've noticed that i would have to divide by 100 to get the same values as in the DW, so i've used AVERAGEX:
The results were, respectively: 701,68; 2120,60...; -669,441; and finally **-694,74** for Avg_FMPdollar.i can't understand the difference to SQL calculation, since calculations are similar to the other ones. After that i've tried:
test:=SUM([_FMPdollar])/countrows('Fct Sales') AND the value was EQUAL to SQL: -672,17 test2:=AVERAGE('Fct Sales'[_Frontend Margin Percent ACY]), and here, without dividing by 100 in the end, -696,74...
So, AVERAGE and AVERAGEX have a diferent behaviour from the SUM divided by COUNTROWS, and even more strange, test2 doesn't need the division by 100 to be similar to AVERAGEX result.
I even calculated the number of blanks and number of zeros on each column, could it be a difference on the denominator (so, a division by a diferente number of rows), but they are equal on each row.
I have a temp_max column and a temp_min column with data for every day for 60 years. I want the average temp for jan of yr1 through yr60, averaged... I.E. the avg temp for Jan of yr1 is 20 and the avg temp for Jan of yr2 is 30, then the overall average is 25. The complexity lies within calculating a daily average by month, THEN a yearly average by month, in one statement. ?confused?
Here's the original query. accept platformId CHAR format a6 prompt 'Enter Platform Id (capital letters in ''): '
SELECT name, country_cd from weather_station where platformId=&&platformId;
SELECT to_char(datetime,'MM') as MO, max(temp_max) as max_T, round(avg((temp_max+temp_min)/2),2) as avg_T, min(temp_min) as min_temTp, count(unique(to_char(datetime, 'yyyy'))) as TOTAL_YEARS FROM daily WHERE platformId=&&platformId and platformId = platformId and platformId = platformId and datetime=datetime and datetime=datetime GROUP BY to_char(datetime,'MM') ORDER BY to_char(datetime,'MM');
