Average Transactions By Weekday
Jan 25, 2008
Hi,
I have a transaction file containing a year's worth of transactions with a date/time field that tells me when the transaction took place. I'd like to write a view (or perhaps multiple views) that tells me the average number of transactions per weekday.
I've been messing around with DATEPART and I can calculate the *total* number of transactions that took place on a Monday, for example, but I can't figure how to do the *average* number. My problem seems to be calculating the number of Mondays there were in the year. Or overthinking it.
Any suggestions would be greatly appreciated.
Thanks,
Jennifer

I try to make the following:
select DATENAME(WEEKDAY,[date]) as DAY, sum(earnings) as Earnings
from myTable
where DATENAME(WEEKDAY,[date]
in ('monday','tuesday','wednesday','thursday','friday')
group by DATENAME(WEEKDAY,[date])
order by DAY
this query works very well except the last line. the last line causes SQL-Server to order the days in an alphabetical order.What do I have to do that SQL-Server orders the days according to their natural appearance (monday, tuesday, wednesday, thurs......)

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.

Hi!
Im experiencing problems with datepart(weekday,...) function. In particular with week 54 of 2000... (by the way, dont make a bet about that, because Jan 1st. was saturday (last day of week) and year 2000 was a leap year!!!, so Dec 31 became the one and only case of 54 weeks... in our calendar).
Is there a way I can fix sunday as first day of week, instead using SET DATEFIRST in every procedure? (because "somebody" puts MONDAY as a default in spanish)
Thanx in advance,
Csar.

Hello Guys,
I'm going crazy tring to figure out how to generate a report that execute a Store procedure and then give me a total Per WeekDay and group it by Part Number.
For example my data should look like this
(PartNumber-Monday-Tuesday-Wednesday-Thursday-Friday-Saturday-Sunday-)
The report will give me a list of all available part and the sold sold per part per day.
Thanks in Advance.

Sql server 2000 -sql query analyzerselect datename(dw,'01-01-2006')returns sundayNow I do:set language danishselect datename(dw,'01-01-2006')returns sonday. But it should be sndag. Same goes forsaturday/lordag/lrdagTried substring'ing and ascii'ing/unicode'ing and it is AFAIK an o insteadof the special danish character .Is this a "feature" or am I doing something wrong?I "solved" it by doingselect case DATENAME(dw,'01-01-2006') WHEN 'lordag' THEN 'lrdag' WHEN'sondag' THEN 'sndag' ELSE DATENAME(dw,'01-01-2006') ENDbut it sure aint pretty./jim

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:
NAME_________________CO
-------------------- --
OFFUTT AFB___________US
MO______MAX_T _____AVG_T__MIN_TEMTP_TOTAL_YEARS
-- ---------- ---------- ---------- -----------
01_________21______-5.31________-30__________60

Hi All,In ASP.Net, I am passing a date as a string formatted as yyyymmdd (e.g. 20080219) via an SqlParameter as follows:aSqlParams(0) = New SqlParameter("@DepartDate", inpDepartDate.Value)In the Stored Procedure (SP) I am using DATEPART(dw, @DepartDate).If I execute the SP from within SQL Server and enter a date, formatted as above, as tha value for the Parameter @DepartDate then DatePart returns the correct value (3).If I use the SP via ASP.Net it returns a value which is 1 less (2). When I execute the SP manually the resultant EXEC statement uses "@DepartDate = N'20080219'". Can something similar be done in ASP.Net when setting the SqlParameter? Thank you,

In a table, I store an integer to represent a day of the week (1 = sunday ) and then in procedures, compare that to datepart(dw, getdate()) to do alternative tasks on certain days.
If I have the number 1, is there a built in function to convert that to sunday or should one just write a function to do just that?

In my SSRS report i have a date parameter and i want to set to it a default value with a complicated logic. I arrived at this strange behaviour:
Today is May 6th, wednesday. If i use the following expression:
DateAdd("d",Weekday(Today(),DayOfWeek.Sunday),Today())
for the default time picker I get May 9th. If I use exactly the same expression in a textbox in the same report
DateAdd("d",Weekday(Today(),DayOfWeek.Sunday),Today()).ToLongDateString()
I get May 10th! The only thing that changes is the toString. Why are the two values different? I tried with different expressions and the difference arises when i start using Weekday(Today(), somevalue).
The result of Weekday should be independent from regional settings as I am forcing Sunday to be the first day of the week, right?

Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated

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....

as
select sum(case when orders.orderdate between @prevMonthStart and @prevMonthEnd then 1 else 0 end ) as PrevMonthCount,
sum(case when orders.orderdate between @thisMonthStart and @thisMonthEnd then 1 else 0 end ) as ThisMonthCount
(how do I add in the average for both months? The column is orders.ordertotal)

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
(
STRTOMEMBER("[Team Project].[Team Project].["+@Project+"]"),
STRTOSET(@IterationParam),
STRTOSET(@AreaParam),
STRTOSET(@WorkItemTypeParam)
Does anyone have any suggestions?
Thanks,

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.
Shifts | Mon_day | Mon_Night | Tue_Day.....
Average | 5.2 | 10.2 | 15.2........
The codes that i tried..
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

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.
I need to insert that code to the existing code that I have if it is possible(which my boss prefer); or either if i can manipulate it in SQL reporting services in visual studio 2005.
Here is a sample output that I have.Each phase has a different color.
Here is the code that i used

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
00001 shake 2.00 1 2.00
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!
Thank you so much!

I am trying produce 144 record average based on any date spread in the where clasue. 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. Looking for any assistance.
