Firstly, sorry for the long post, but I've included a fair bit of
sample data.
Im doing a comparision of 10yr Bond prices and CPI adjustments, with
an 18 week moving average of the CPI. I'm using a nested sub-query to
calculate the moving average, but I'm having difficulty selecting
exactly 18 data points (ie When I include the 'HAVING COUNT(C1.Closes)
= 18' line, I get no results).
Can anyone help?

I trying to get the moving total (juts as moving average). It always sum up the current record plus previous two records as well and grouped by EmpId.For example, attaching a image of excel calculation.
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,

Hi All, I am trying to create a report that shows moving average. Well I found this template:
// /*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";
Only I do not have a specified interal or a constant number that I can place into
.Lag(<<Periods to Lag>>) The report I have has a parameter that allows you to select a specific team project from a list. Although I have not figured out how to get the iteration paramter to update to only show the specified team project iterations, I want the graph to only show the iterations for that team project and the moving average (in the graph). The problem is that I can't just plug in the number 6 because different projects we have, have different numbers of iterations, and the user can pick any project from the list in the parameter.
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 am attempting to find a moving average for gas production per gas well over a 3 month period. I also would like to only keep the records in which the average of the previous 3 months is less than or equal to 90. My table roughly looks as such:

I would like to find the average of the last 3 months, or last 3 records.
Im quite new to SSRS and SQL in general and i've found this site to be a goldmine, and I found a thread on here relating to moving averages but I don't think it meets my needs.
I have a simple bar chart in SSRS with a Category Field (Fields!WeekYear.Value) which has the week number and year value on the axis, and a Data Field (Fields!Amount.Value) which is just a quantity for the given week.
Now what I need is a Moving Average of the amount with each new week generated (Simple and 3-point and/or 5-point), I've tried using some code and even functions but nothing is working for me so I was wondering if anyone here can help me out?
PS I've been tinkering with the RunningValue function and my DataSet is called "Cube" so I assumed that the scope should be "Cube" aswell but it only returns an error, am I right or am I being retarded?
As I say I am very new so please be gentle with me :)
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 have a table when user add new sales or puchase will be added to this table ITEM_TXNS. The above date is part of the table for a ProductID . (The field is removed here) In order to calculate the balance amount using moving average, I must calculated the cost_out_amt first on the fly. When user add new sales I also need to determine the cost/unit for a product id using moving average. The problem is I can not just use sum, because i need to determine cost_out_amt for each sales first which will be calculated on the fly. The reason i dont store the cost_out_amt (instead calculate on the fly) because User could Edit the previous sales/purchase txn or Insert new sales for a previous date. Example THe record with ID 9. By Adding this txn with ID 9, would cause all the cost_out_amt will be incorrect (Using moving Average) if i store the cost_amout_out on entrying txn and need to be recalculated. Instead I just want to calculate on the fly and able to determine the cost avr for a specific point of time. Should I just use Cursor and loop all the record and calculate the cost or maybe I can just use on Select Statement?
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?

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.

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?
Hi, I have two tables, Weekly and AverageEngTime. Weekly table has 14 columns, "Mon_Day,Mon_Night,Tue_day,....Sun_Night". AverageEngTime table has 15 columns, "Shifts,Mon_Day,Mon_Night,Tue_day,....Sun_Night". I have inserted "Average" as a value for column "Shifts" in AverageEngTime table. Now how do I find the average for each column in Weekly table and insert into AverageEngTime table in the respective columns, and in the row where Shifts = "Average".
I used the following codes to try but i receive errors at where statement.Please correct me. The expected output as below.
declare @Weekday tinyint, @hour int select @Weekday = datepart(dw,getdate()),@hour= datepart(hh,getdate())
if (@Weekday= 1 and (@hour>= 7 AND @hour<19)) begin Insert Into AverageEngTime(Sat_Night) where Shifts = 'Average' SELECT AVG(Sat_Night) FROM Weekly end
if ((@Weekday= 1 and @hour >= 19) OR (@Weekday = 2 and @hour < 7)) begin Insert Into AverageEngTime(Sun_Day) where Shifts = 'Average' SELECT AVG(Sun_Day) FROM Weekly end
