Hello,
I have two tables:
[Posts] > PostId, ...
[Ratings] > RatingId, PostId, Rating
I want to select all posts and add a new column named AverageRating.
This new column is the average of all ratings associated to that Post.
If a post was not rated then its AverageRating would be NULL.
How can I do this?
Thanks,
Miguel
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:
Avg_AMP:=AVERAGEX('Fct Sales';'Fct Sales'[_AMP]/100)
Avg_AMPdollar:=AVERAGEX('Fct Sales';'Fct Sales'[_AMPdollar]/100)
Avg_FMP:=AVERAGEX('Fct Sales';'Fct Sales'[_FMP]/100)
Avg_FMPdollar:=AVERAGEX('Fct Sales';'Fct Sales'[_FMPdollar]/100)
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');
with a result of:

Hi !
I am having this problem. I have a grouping someting like this.
Group1
Resolved Resolution Time Average Resolution Time
30 2904.46 96.82
54 1442.03 26.70
0 0.00 0.00
0 0.00 0.00
------------------------------
Avg : 30.88
Now to calculate the average inside the grouping I have used this
iif(Sum(Fields!ResolutionTime.Value) = 0 ,"0.00",(Sum(Fields!ResolutionTime.Value)/(iif(Count(Fields!ResolvedDate.Value)=0,1,Count(Fields!ResolvedDate.Value)))))
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.
Any ideas will be greatly appreciated.
Thanks in advance.

Hi All,
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.
WITH
MEMBER [Measures].[Date Key] AS
[Date].[Date].CurrentMember.UniqueName
SELECT
{
[Measures].[Date Key],
[Measures].[ComplexityRank]
} ON COLUMNS,
(
[Work Item].[System_State].[System_State],
(StrToMember(@StartDateParam):StrToMember(@EndDateParam))
)
ON ROWS
FROM [Team System]
WHERE
(
STRTOMEMBER("[Team Project].[Team Project].["+@Project+"]"),
STRTOSET(@IterationParam),
STRTOSET(@AreaParam),
STRTOSET(@WorkItemTypeParam)
)
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)
WITH
MEMBER
[Measures].[Date Key] AS
[Date].[Date].CurrentMember.UniqueName,
[Measures].[Moving Average] as
AVG({[Date].[Date].currentmember.lag(@IterationParam):
[Date].[Date].currentmember},[Measures].[ComplexityRank])
SELECT
{
{measures.[moving average],measures.[Internet Total Product Cost]} on 0,
[Date].[Date]. Members
[Measures].[Date Key],
[Measures].[ComplexityRank]
} ON COLUMNS,
(
[Work Item].[System_State].[System_State],
(StrToMember(@StartDateParam):StrToMember(@EndDateParam))

ON ROWS
FROM [Team System]
WHERE

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?

I made a code to in SQL reporting services for the reports of our company regarding the new applicants. Now I need to get the average datedifference in each phase from all applicants who entered Initial/Data Collection. Example, "Initial/Data collection"PHASE will have an average of 60 minutes to be finished, averaged from all 200 applicants, and "Screening"PHASE 240 minutes to be finished, averaged from 100 applicants.
All applicants must go through stage 1 before he can go to stage 2 and so on.
The date diff will be obtained from the "createdon" column subtracted to the last "modifiedon" column in each phase.

Hello Sql Expert!
I am trying to create a query that i can use to find the Average Check for transactions sold with a particular product.
The sql table i'm working with looks like this
ORDERID PRODUCT PRICE COUNT PAID
00001 burger 1.00 1 1.00
00001 hotdog 2.00 2 4.00
00001 drink 1.00 1 1.00

00002 burger 1.00 2 2.00
00002 shake 2.00 5 10.00
00003 hotdog 2.00 1 2.00
I would like to create something that will give me the average check for every product
ex
PRODUCT AVG CHECK
burger 10
shake 10
hotdog 5
drink 8
I created a query that could give me the % of each product that are ordered alone. I tried modifying it to give me avg check but ran into problems because the when i use max(product) to aggergate the field, it uses the products with the highest first character in the alphabet thus it products with V's and Y's get a lot more results (
Is there an easy way to do this by creating a temp table or nested query?
I can create a nested query to give me the average check for only one product at a time. I'm looking for something that can group the average check by all product.
Any help would be greatly appreciated!

For example if the where is time_stamp between '01/01/2007' and '01/03/2007' this would be 288 records however the ouput needs to always be grouped into 144 records maximum.

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.
Does anyone have suggestions on this?
Thanks!

I am using an expression to create an average. The result is an odd number like 33.666666666666667.
I want to round this to 34 (I would even accept 33, or 33.67), just not so manny digits to the right.
Just want to gathr some ideas.I have a matrix where i retrieve Fields!Amount.I used the subtotal property to get the total amount per quarter.But how can i get the average of the 3 months.I tried using the Avg(Fields!Amount.Value) but it's results is unexpected or wrong.
________________________
| Avg(Fields!Amount.value) |
| Jan | Feb | March |
-------------------------------------------
| 0.1 | 0.2 | 0.2 |
| 0.3 | 0.1 | 0.5 |
SubTotal | 0.4 | 0.3 | 0.7 |
That is the design of my matrix.And other thing,it is dynamic,for example,There is a possibility that Feb could be absent.SO i cannot make Sum(Fields!Amount.Value) / 3. Dont know what to do for that.Why could Avg be wrong, correct me if im wrong,but as for what i know,i think the formula for Avg in my matrix is :
Avg = Sum of 3 totals / no. of months..
Hope to hear from anyone out there..Thanks!!

I don't even know if this is possible but here is a picture of some sample results.
Description Amount Account Location Begin Balance

Test 2345 $50 0001 Las Vegas $5000
Test 3456 $80 0001 Phoenix $2000
What this is, is transactions and their amounts and account/location they went to. The last column is the beginning balance for the account/location combination. I only need the beginning balance once per account/location or averaged. So I need either this (beginning balance only shows once).....
Description Amount Account Location Begin Balance
Test 1234 $100 0001 Las Vegas $5000
Test 2345 $50 0001 Las Vegas $0
Test 3456 $80 0001 Phoenix $2000
or I need this (beginning balance is averaged)......
Description Amount Account Location Begin Balance
Test 1234 $100 0001 Las Vegas $2500
Test 2345 $50 0001 Las Vegas $2500
Test 3456 $80 0001 Phoenix $2000
That way I can do a sum on the beginning balance results in my report for the account/location combination, and do a sum on just account or just location while still having my transactions.
Is this possible?

Hi,
I have the following table:
OrderNumber varchar(15)
Completed int(1)
Certificate int(1)
ThroughputTime int(4)
With the following data:
OrderNumber Completed Certificate ThroughputTime
00001 1 1 1
00002 1 1 2
00003 1 0 1
00004 1 0 1
00005 0 1 2
00006 0 1 1
00007 0 0 4
00008 0 0 89
I have a dimension:
All Completed
- Completed
- Not Completed
and a dimension:
All Certificate
- No Certificate
- Certificate
I also have a measures:
TptSum which Sums ThroughputTime
TptCount which Counts OrderNumbers
TptAvg which divided TptSum by TptCount
My problem is with the next measure:
In MSAS I created a Cube which shows the measures on the columns and both Completed and Certificate on the rows. The OrderNumber selection is set to "All Ordernumbers". The measures a listed above are displayed exactly as i expect them to do. TptSum gives the sum for the subselection showed on the left. TptCount and TptAvg also show the expected values on their distinct rows.
I can't upload a screenshot but it looks like this:
TptSum TptCount TptAvg
All Certificate All Completed 101 8 12.63
Completed 5 4 1.25
Not Completed 96 4 24.00
No Certificate All Completed 95 4 23.75
Completed 2 2 1.00
Not Completed 93 2 46.50
Certificate All Completed 6 4 1.50
Completed 3 2 1.50
Not Completed 3 2 1.50
So far so good. Each datarow only takes the records that match the criteria at the left.
Now however, To exclude exceptions that have a huge impact on the average I want to create a trimmed average. That is, I want to exclude the top 25% values in my trimmed average measure, which are the 2 records with the highest ThroughputTime, being ordernumber 00007 and 00008 in the "All Certificate" & "All Completed" row, but different in the other rows. I also want the bottom 25% values to be trimmed, which are the 2 records with the lowest ThroughputTime, being ordernumber 00001 and 0003 in the "All Certificate" & "All Completed" row.
I tried a lot of things, but i can't get it working. Somehow all my statements don't take the subselections on the rows into account. Really frustrating.
What I want to achieve is the following:
TptSum TptCount TptAvg TrimmedAvg
All Certificate All Completed 101 8 12.63 1.50 ((2+1+2+1) / 4) (middle 4 records)
Completed 5 4 1.25 1.00 ((1+1) / 2) (middle 2 records)
Not Completed 96 4 24.00 3.00 ((2+4) / 2) (middle 2 records)
No Certificate All Completed 95 4 23.75 2.50 ((1+4) / 2) (middle 2 records)
Completed 2 2 1.00 1.00 ((1+1) / 2) (all 2 records)
Not Completed 93 2 46.50 46.50 ((4+89) / 2) (all 2 records)
Certificate All Completed 6 4 1.50 1.50 ((1+2) / 2) (middle 2 records)
Completed 3 2 1.50 1.50 ((1+2) / 2) (all 2 records)
Not Completed 3 2 1.50 1.50 ((1+2) / 2) (all 2 records)
I hope I describe my problem well... I also hope someone knows a solution. I can also post the things I tried, but I'm afraid that makes it more confusing, because nothing worked ;)
Thanks,
