It seems to be subtracting the value of field3 from the total of 3 fields at some points instead of giving me the average.Some of the results are here:

I want to calculate average row size of a record. By based on this i want to add some more columns into an existing table. Here is my table structureCREATE TABLE patient_procedure( proc_id int IDENTITY(1,1) CONSTRAINT proc_id_pri_key PRIMARY KEY, patient_id int NULL, surgeon_name varchar(40) NOT NULL, proc_name varchar(20) , part_name varchar(30), wth_contrast int , wthout_contrast int , wth_wthout_contrast int, xray_part varchar(60), arth_area varchar(30), others varchar(30) , cpt varchar(20) , procedure_date smalldatetime NOT NULL, mraloperrun varchar(20),CONSTRAINT patientid_foreign_key FOREIGN KEY(patient_id) REFERENCES dbo.patient_information (Patient_id)) Now i got a requirement that i have to add two more procedures with different columns.The columns overall size is 195 bytes.I can place those two procedures as seperate tables. I dont want to do that becuase of front end requirements.Here the problem is when the user enters these two procedures information remaining fields will store the null value. I know that when we store the null values into corresponding columns min of 1 byte will be occupied. Please suggest me that shall i include these columns into the above table. If i add these columns is performance will be decreased or not. Waiting for valuable suggestions.
An example of 4 rows on my table would be like this $1400 80 $1500 85 $1560 82 $1700 81
to calculate the average of the price sold related to the number of sold items just have to do Select avg(priceSold*itemsSold)
But sometimes i just want the average price of the first 100 sold items, so how can i make my query to just use the first 100 sold items?
in math it would be like this average= ( (1400*80) + (1500*20) ) / 100
but if i wanted the first 200 it would be like this average= ( (1400*80) + (1500*85) + (1560*35)) / 200
and if i wanted the first 300 would be like this average= ( (1400*80) + (1500*85) + (1560*82) + (1700*53)) / 300
but of course the number i want will always be a variable which is less than the total of the products sold. So, how the heck do i program this query where the number of the items sold is variable and it will take the rows of the database depending on how many items were sold.
I hope i didnt wrote my explanation too confusing and that i can get any help from you guys. thank you a lot for the help and byye
Hi, How do I Calculate Average Leadtime... I have a Table named "iCalls_Calls" which has 2 Columns (start_Date and Closed_Date).I need to calculate average leadtime based on the columns from this table . I have a query and i need to add this ( calculate average leadtime) to this query.
Code:
SELECT B.USER_DIVISION,B.USER_DEPARTMENT,COUNT(*) FROM iCalls_Calls A INNER JOIN iCalls_Users B on A.REQUESTOR = B.USER_ID GROUP BY USER_DIVISION,USER_DEPARTMENT
Can anyone send me the correct query to calculate the average time ? Thanks..
I've got a statistics table that I've been writing to for about 2 years now. Every saturday night, a size (in MB) snapshot of each DB file is taken and dumped into this table. I'm then emailed a copy for that week.
Now, I'm trying to figure out what the fastest growers are. Here's the table ddl
What I'm trying to figure out is how to query the average monthly and yearly growth percentages per DB on the MDFSize column.
I'm usually pretty good at this sort of thing, but I just can't seem to wrap my head around how to solve this issue. I'm not having a very good math day.
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?
I need calculating a rolling 3 month average cost from the two dataset below. Which is the 3 month Average of Dataset1 / Dataset 2.
Dataset 1:
SELECT(factAdmissions.ContractCode + '-' +factAdmissions.BenefitPlanCode) AS [Contract Code], factAdmissions.AdmitCCYYMM, ISNULL(sum(AmountPaid),0)As [Amount Paid] FROM factAdmissions
[Code] ....
Dataset2:
Select
(factMembership.ContractCode+'-'+ factMembership.BenefitPlanCode) As Product, EffectiveCCYYMM, ISNULL(count(Distinct MemberId),0) As MemberCount From factMembership Where EffectiveCCYYMM >= '200701'
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 3 tables, each with a date(it has daily dates) column(column name is same in all tables) Each table has columns say "value1","value2", "value3"
i want data from all these tables together.such that my first column will have data weeks and other 3 columns count1,count2,count3 will have average of next 4 weeks count..placed infront of week.
I work for a school district and new requirement we were just given for scoring some student scores.
Everything will currently be in one table to keep track of students test scores for various things. This table will contain students information and a student will be shown more than once in the table. The Student ID is what we will key off of to find the multiple instances of the student. The table contains the following columns: studentName, StudentId, teacherName, focus1, controllingIdeas1, reading1, development1, organization1, conventions1, and contentUnderstanding1. All of the columns with a 1 at the end will be numeric values with possible decimal values.
What we need to be able to do is some how perform a search for these multiple entries of each student and when found, average the 2 scores for each 7 test categories. The result needs to be a single line for each student that gives the student name, student id, and the 7 test category averages exported to an csv file.
Hi,I am trying to add a staggered running total and average to a queryreturning quarterly CPI data.

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');
I have to caculate the fifo inventory aging from purchase date, for example I have one item with 100 units in stock, and purchase this month 20 units, and 200 units three month ago, this item has 20 units this month and 80 units from 3 month ago.
Data is as follows: <<<<< ORIGINAL DATA >>>>>>>>>>>>>>>>
I have a requirement where i need to calculate the age of a work order excluding the Weekends (Sat,Sun) in an SQL table, this i need to updated as a formula for a particulay column in the SQl table so when a task startdate is enterred and submitted the Age field gets populated with the number of working days.
Example: startdate = '04/09/2010' currentdate = '04/12/2010' the result should show 1 day and not 3 days.
I am trying to create a "Loan Ledger Card" in SSRS which does the calculation up to report extracting time. I was able to create it on Excel (Click to download the Excel file) as we can calculate amounts for each installment based on Row and Column name. You can test it by putting any amount (Here it should be below 62000 as it is the total balance of loan) in "Amount Paid" yellow cell and see the effect.
I have made a selection in SQL (attached query and result in screenshot). It calculates the total paid amount by now on the first row, and all due amounts in other rows. Basically, It should first deduct the interest from first row, then principle, same process for second row and so on until it covers the whole paid amount.
SELECT '0' As RN ,memrepay.lnr ,'Repayment' AS Type ,SYSDATETIME() AS NOW ,SUM(memrepay.mprinc) As PrincPaid ,SUM(memrepay.mint) As IntPaid
[Code] .....
How can I do the similar calculation of Excel file in "SQL query" or "SSRS custom code"?
Table2: TransactionFormula Only has 2 fields, No & Amount
the formula fields means, we sum the Amount from TransactionFormula table for each No., for example if the formula is [3]+[8] means, we sum the Amount from No=3 added with the Amount from No=8 and we added records on TransactionFormula for row 9
Here's the example result for TransactionFormula records
Hello, I am very new to SQL and just getting to learn this stuff. To make this question easier I will scale down the fields dramatically.
I have about 8000 records close to 2000 records for the last 4 years and I would like to create a query that will create a table on my SQL server. I need to bind the data based on two items the Year and the Name and average several records. However, one record needs it's own calculation.
Here are my field names: [year] ***4 choices 2007, 2006, 2005, 2004*** [name] [rush_no] ***integer*** [rush_net] ***integer*** [YPC] *** This field needs to be calculated by [rush_net] divided by [rush_no]***decimal***
I also need to create the same table that will "total/sum" the same records.
Hello,I have two tables:[Posts] > PostId, ...[Ratings] > RatingId, PostId, RatingI 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
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?
