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 have also added an image oh how the matrix looks like.
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?
Hi AllWe have an order processing database which includes the standard OrderHeader/Order Lines tables. I'm trying to write a query to get the averagenumber of lines per order over a given period, and I'm stuck :-(I can get the number of lines per order with:SELECT COUNT(*) FROM OrderDetailsINNER JOIN Order Header ONOrderHeader.OrderNo = OrderDetails.OrderNoWHERE OrderHeader.OrderDate ..... {various criteria} ...GROUP BY OrderDetails.OrderNumberBut how do I then get an average of this for the period?TIAMike Bannon
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?
This is an SPC chart controlled by a slicer that operates a powerpivot table. This is then copied (by cell formula) into a "normal" table where the average, UCL, LCL and Erlang are calculated which are just basic calculations involving average and standard deviation. To make it work the values in the Average, UCL,LCL and Erlang must be repeated all the way down the table to create the chart. In the current format it works well and using a standard table keeps the chart range dynamic.
However this is a very clunky solution involving repeating the data tables in excel. I need to create dozens of charts and it will get large and slow.I would like to create the whole thing in a powerpivot table using measures so i can use powerpivot charts and ultimately powerBI. The data column PasID is a text column so I need a measure that calculates the "count of PasID" for each day(the row labels) and then repeats that value down a whole column in the same way the standard table does. I couldn't figure out how to get the correct number repeat down the whole column, which measures to use,Whether to create calculated columns in the data model or any of it. SO I need to be able to get a count of a text column then display the average of that count in a second column all the way down.
how to return the 3 month rolling average count per username? This means, that if jan = 4, feb = 5, mar = 5, then 3 month rolling average will be 7 in April. And if apr = 6, the May rolling average will be 8.
Columns are four:
username, current_tenure, move_in_date, and count.
DDL (create script generated by SSMS from sample table I created, which is why the move_in_date is in hex form. When run it's converted to date. Total size of table 22 rows, 4 columns.)
CREATE TABLE [dbo].[countHistory]( [username] [varchar](50) NULL, [current_tenure] [int] NULL, [move_in_date] [smalldatetime] NULL, [Cnt_Lead_id] [int] NULL ) ON [PRIMARY] GO SET ANSI_PADDING OFF GO
Which works fine for all my other calculations except this, where I need a distinct count. CNT is a calculated measure. The browser would look like this:
Category Year1 Year2 ..... MDX what I have now MDX what I need
I have two tables - one with dates at the end of each month (10/31, 11/30, 12/31, et al) that's linked to a data table containing client signups. While I can get the count per month in a pivot table, I'm trying to calculate the beginning count of each month.
How do I use calculate or something similar to sum the count of records created minus count of records closed prior to the beginning of the period?
The pivot looks like this right now and works by month:
beginning active records ????? count of records created 100 count of records deleted 50 net records created 50 running balance in net records created 100 (theoretically the next month's beginning balance, but can't figure out how to reference or calculate)
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 ''): '

I am getting the number of transactions for two different months based on dates entered from the user. I need to display the number of transactions along with the average sale. I have figured out how to get the dates and sum the transactions but I can't seem to add in the average....
I am at a loss how to calculate the group footer (Result = 30.88 ) which is equal to (96.82 + 26.70 + 0 + 0 ) / 4 . This is the result from the existing Crystal report. I am trying to convert this report to reporting services. Now I cannot nest aggregate functions and also the row number can be dynamic I am confused how to resolve it.
I was hoping someone could help me with pluging moving average into my report.
This is the template I am using for moving average: // /*Returns the average value of a member over a specified time interval.*/ CREATE MEMBER CURRENTCUBE.[MEASURES].[Moving Average] AS Avg ( [<<Target Dimension>>].[<<Target Hierarchy>>].CurrentMember.Lag(<<Periods to Lag>>) : [<<Target Dimension>>].[<<Target Hierarchy>>].CurrentMember, [Measures].[<<Target Measure>>] ) // This calculation returns the average value of a member over the specified time interval. FORMAT_STRING = "Standard";
This is what I have before I started to add the moving average. The report works but only displays the cummulative complexity rank.
What I want to do is also add the moving average for this over the parameter of Iterations. (IterationParam). This is what I have so far with the moving average in my report: I know I must have a lot of errors but I can't get past this first error. I highlighted the line with error. The error said: Query(7, 15) Parser: The syntax for '.' is incorrect. (msmgdsrv)
I have two tables, table a holds all the votes by users of each element in table b. I was wondering, how do I get the average of all those votes in table a that relate to that each instance of a element in table b. For example table b has two elements created by a certain user that has been voted 5 times each by users with scores like 2, 5, 4, 2 , 2 for both of them. I just need to get the average of those numbers that pertain to those elements in table b. Thanks for any help.
Hello all!This might be a newbie question, and there might be something Im just not thinking of right now, but I have a set of values that I need to get the average of but only from the middle 90%. Example:11 <-From here1234456 <- To here.7I thought I could solve it by subqueries and do the following:Select (((Select sum top 5 order asc) + (Select sum top 5 order desc)) - sum total)/rows*0.9 which would give me what I want, but I realised that when aggregating I cant order the subqueries.This is for an application (that will run the query on a sql-server) that only takes one query (although subqueries should be fine), and thats why I have a problem, I cant build any views or things like that.I guess my question is very simple: How can I get a sum of the bottom 5 percent without sorting descending?
