I have a database containing values in 16 fields. the fields are filled in over a period of three years. I would like to be able to calculate the average of the last four values entered, regardless of when in the cycle the value is required. I have tryed to use quereies but connot find away to assign the four fields to the expression so that it is the last four values and if four don't exist, avearage what values there are.

Hi Guys,
Im in need of some help with a query that i am trying to set up. I have a table with data shown roughly below. And need to extract the average [call length] for each heading of [Call type] on a given date.
Ie. The query will be run and the date can be inputted. It would the display each category only once and the average of that category.
Call type |Call Length (Shown in Minutes)|Submitdate

Is there a way to calculate three different rolling averages in one query?
I just inherited a database where someone is using three queries to capture the same information only with different time frames. They were calculating a rolling three month average, six month average, and twelve month average. I would like to combine these queries into one to reduce time spent running reports from the database. All three queries are based on one table. One of the columns in that table is called "Month Start Date". That field shows the first day of the month when a call was entered. I can get the query to tell me the first month in the three month period and the first month in the six month period, but I can't get it to calculate the averages of the calls that fall in those time frames. Here is the SQL for the query I have now. When I try to run this, I get the error message that my formula is not part of an aggregate function.
Code:
SELECT DISTINCT DateAdd('m','-2',(Max([Month Start Date]))) AS ThreeMonthStartDate, DateAdd('m','-5',(Max([Month Start Date]))) AS SixMonthStartDate, Max([Month Start Date]) AS MaxStartDate, IIf([Month Start Date] Between [ThreeMonthStartDate] And [MaxStartDate],Avg([All Call Rate]),' ') AS ThreeMonthAverageCallRate, LIST_WITH_TNC.Device, LIST_WITH_TNC.Model, LIST_WITH_TNC.[Item Num]
FROM LIST_WITH_TNC;
Is there a way to make this work?
Let's say I have a table sort of like this one: [URL] .... (Table 1)
What I want to do is make another table that references the first table: [URL] ... (Table 2)
I want the cells in the Average field in Table 2 to calculate an average of all the values for records in Table 1 with Color fields that correspond to the Color field in Table 2 (this makes a little more sense if you look at the pictures). I could do this in Excel, but then problems would arise whenever I would add a new entry to the database, or re-alphabetized the data, since Excel math is depends entirely on the positions of cells, and I want these averages to be continually calculated correctly and to change whenever I add related records to the database.
Hi guys...

Hi,
In my database, I have clients and client hours. I need to calculate average client hours. My total client hours expression is: TTotals: Sum((Nz([SessionHoursCompleted])+Nz([OptionalHoursCompleted]))). I need to divide this number by the number of clients.
Any suggestions ie sum of client number, sum of clients, count of clients.
I've tried these and the results are incorrect.
Thank You
I am trying to calculate the average patients age from 2671 records using this SQL:
SELECT tbl_Customer_Details.DOB, CalcAge([DOB]) AS Age, DAvg("[Age]","qryAvgAge") AS Average
FROM tbl_Customer_Details
GROUP BY tbl_Customer_Details.DOB, CalcAge([DOB]);
why am I getting the result:
68.1131066106
I would have thought that it would have been 68 a whole number, has anyone got any suggestions why this should be.
thanks
Right, So i've got a table which has records for the Top 40 Music Charts.
I want to be able to find out the averages for each song taken from it's positions in the chart over the weeks:
http://www.playfm.orcon.net.nz/Chart4.GIF
So essentially I get something that tells me
[Lenny Kravits] [American Woman] [24.5]
[Silverchair] [Ana's Song (Open Fire)] [41.1]
and so on...
Any ideas?
Cheers guys,
Alex.
I have developed the following query to summarise a blast design at a mine site.
Pattern Depth m Subdrill Burden Spacing BCM/hole #Holes BCM
1.00 7.00 1.00 3.00 3.00 54 10 540
1.00 7.00 1.00 3.50 3.00 63 10 630
2.00 7.00 1.00 3.50 3.00 63 10 630
2.00 7.00 1.00 4.00 3.00 72 10 720
Now there will be many patterns, the above however only contains one (called 1). Now what i need is the average Depth, Subdrill, Burden, Spacing, bcm/h. In MS Excel I would have following:
Average BCM per hole = Sum of BCM / Sum of Holes
How to do this in Access? Then just to make it more difficult I want to have the average BCM for each different pattern.
Hi there,
once again I have a problem for which I am looking for some hints...
I still have one table, called tblTransactions, which contains security market transactions. For each buy and sell order, respectively it contains one data set with columns Date, Ticker (i.e. the unique identifier of each security), Quantity (positive for buy, negative for sell orders) and Price (at which the trade was executed).
The following code gives me all stocks, which are no longer part of the portfolio since they have been sold out completely for any arbitrarily chosen date (here 1/30/07) together with the date, on which the last position in a certain stock (identified by the ticker) were sold:
SELECT T.Ticker, max(T.Date) AS SellDate
FROM tblTransactions AS T
WHERE T.Date<=#1/30/2007#
GROUP BY T.Ticker
HAVING sum(T.Qty) =0
ORDER BY T.Ticker;
Now it becomes complicated: What I am looking for is a sub-query, which I want to add to the code above and which gives me the weighted average price at which the stocks were bought and sold, respectively if there have been more than one buy or sell transaction.
That is, for the following sample data of tblTransactions...
Date --- Ticker --- Quantity --- Price
01/01/07 --- AAA --- 50 --- $50
01/01/07 --- BBB --- 25 --- $75
01/10/07 --- BBB --- 75 --- $100
01/15/07 --- AAA --- 30 --- $60
01/20/07 --- BBB --- -100 --- $100
01/25/07 --- AAA --- -40 --- $120
01/26/07 --- AAA --- -40 --- $100
...the query I am looking for should give the following result as per 01/30/07:
Ticker --- SellDate --- WeightedAvgEntry --- WeightedAvgExit
AAA --- 01/26/07 --- $53.75 1) --- $110.00 3)
BBB --- 01/20/07 --- $93.75 2) --- $100.00
Notes / how to calculate the weighted averages:
1) (50*$50 + 30*$60) / 80 = $53.75
2) (25*$75 + 75*$100) / 100 = $93.75
3) (40*$120 + 40*$100) / 80 = $110.00
I do not have any clue at all how to solve that problem. I would be very happy for any hint that could lead to the right direction.
Best regards

My database has 8 clients. During a sample date range, between 1/1/05 and 1/1/11, they worked a total of 348 hours. I need to query them for hours divided by client by date range. 3 clients, for instance, worked a total of 162 in the sample date range but the query is dividing the 162 hours worked
by all 8 clients. I need it to divide the hours in this case by 3. Needless to say, these numbers will change when a different date range is inputted but if the expressions are correct...
Currently, to calculate this number I am using this expression :
Averages: Sum((Nz([SessionHoursCompleted])+Nz([OptionalHoursCompleted])))/DCount("IDOC","spise clients_OLD_OLD").
A copy of the query 'Current Average/Total' is attached.
Thank you for your assistance.
I have a table containing about 120 records of 40 fields containing integer values. The values are 0 (for 'no experience'), 1 - 5 (for evaluation of experience) and 9 (for question not answered). I would like to generate a row of averages for the 40 columns.
Access includes the '0's when using the Avg function. (So 1,0,3,0,1,4 yields 1.5 (1+0+3+0+1+4 / 6) rather than the accurate 2.25 (1+0+3+1+4 / 4)). I can tackle this in two ways: I either convert all zero's to NULLs, as Access will not count NULL in an Avg function call, or I can do each column in a seperate query using a WHERE clause. I also have the problem of screening out the 9's. I'm reluctant to create 40 queries and then another to amalgamate the results as this seems a very silly way to solve this problem. I cannot convert both the zeroes AND the 9's to NULL as to do so would lose valuable data.
Can anyone suggest how I can obtain a full row of averages for the 40 fields, ignoring 0's and 9's?
I need to create a query where in the end, I will have four rows of data based on based on two combinations of WaterSourceType and Crop.
I need the query to bring back the results of the average Top N (lets say Top 10%) for each combination.
I have tried this every which way and I can't seem to get it grouped like I want it. I NEED to have four distinct rows with the average of the ProfitPerBushel for each grouping.
Basically, what this does is show me the average profitablity of the top 10% in each grouping.
WaterSourceType | Crop | ProfitPerBushel
Irrigated | Soybeans | ProfitPerBushel
Non-Irrigated | Soybeans | ProfitPerBushel
Irrigated | Corn | ProfitPerBushel
Non-Irrigated | Corn | ProfitPerBushel
My database is set up to track call evaluations with 4 fields for number data (S, A/C, C/E and B) each of these have a possible point total. I also have a percentage field to track out of total possible points.When I run my query I get a list of each of the totals for each of the evaluations with the associates names (as expected).I take that query and try to run a report wizard to give me an average socre for each associate. and the system returns averages of 0 or an odd number that does not make sense.when I use the =Avg([fieldname]) process I get an accurate average of the total but can not get it to do a "subtotal" for each associate.

View 6 Replies View Relatedhi all,
i have a mainform with a subform.
in the subform i have 2 fields: duur and subtotaal
in duur i enter a number.
in subtotaal a calculation has to occur: =20*([duur]/60)
i tried to do this calculation in VBA but then i got the same value on every record in the subform.
But now the problem:
in the mainform i have a control 'totaal' that needs to do a DSum of subtotaal.
And here i am getting into troubles since subtotaal is not stored in the table but calculated.
The formulla for DSum would be:
Me.Parent!totaal = DSum("subtotaal", "tblFacturenDetail", "[FactuurID] = " & Me.Parent!FactuurID)
but as said, subtotaal is not stored.
How should i proceed?
Thanks!

I am designing a new database for our life and disability department and they have several different policies where the base life insurance reduces at certain ages.
Please take a look at the scenarios listed below and give me any suggestions and tips on the best way to get this done. If you have any.
Below are the 12 scenarios:
1.) Reduces 75% at Age 70
2.) Age 65 to 70 the life amount is $9,000 and Age 70 and over the life amount is $6,000
3.) Reduces at age 65 by 92%, age 66 by 84.64%, age 67 by 77.869%, age 68 by 71.639%, age 69 by 65.908% and age 70 and over by 40%.
4.) On the day following the 70th birthday, the life amount will reduce to 70%. On the day following the 75th birthday the life amount will reduce to 40% of the 70th birthday reduced amount.
5.) On the Policy Anniversary Date following the 70th birthday - reduces 50%
6.) On the Premium Due Date following the 70th birthday, the life amount will reduce to 70%. On the Premium Due Date following the 75th birthday, life amount will reduce to 40% of the amount of the 70th birthday reduced amt.
7.) Age 65 life amount reduces to 65%. Age 70 life amount reduces to 35%. Age 75 life amount reduces to 25%.
8.) Terminates on the first of the month following the 65th birthday.

Hi,
I am new to Microsoft Access (2002) and the Access Word Forums. I am in need of a way to calculate timespent on six main topics through an 8 hr. working day. If I worked on Topic "A" from 8:00am to 8:15am, I need it to calculate it to 15 minutes. Then I need to figure a way to calculate how much time was spent doing Topic "A" for the working day, then by the workweek, then by the month.
I'm willing to learn, if someone has the time to teach or can direct me to a link that discusses something similar to what I am looking for. Any and all suggestions welcomed. I am looking forward to doing this in a timesheet format if possible.
Thank you,

Hi,
I think this should be simple, but I am struggling to work it out
In a relational database I have a stock table containing stock and quantities, there is a customer table with an order table used as the link table also containing quantities.
What I am trying to do is place an order using an order form linked to the order table, automatically reducing the stock table by the amount ordered.
I have tried an update query with no success, also tried using the builder to make a query and linked it to the stock table with no success.
I would be grateful for any ideas, I am sure it is relatively simple
Hi Guys,
New to the forum, and its nice to see how active this place is, and upto date.
My question is, and probably simple to correct. ( Please be patient with me, i`m new to this, and my terminology might be incorrect, also please simple answers )
I`ve searched the forums, but as my teminology is wrong I cant find the results im after :)
Anyway, I have a table with many fields in it, but the parts i`m having problems with are as follows.
I have fields with
Price Inc Vat, Deposit Payment, Stage Payment, Balance Payment & Balance Due.,
The part im trying to get to work is the balance due which I want to automatically update, based in the data inputed into price inc vat deposit payment etc.
The calculation i`m after is as followes
Balance Due = ( Total Ammount Inc Vat - Depost Payment - Stage Payment - Balance Payment )
eg, Total Ammount Inc VAt = £2000
Depost paid is £1000
so far balance due would be £1000
Then Final Payment is made 2 weeks later £1000
So balance due would then show £0.00
Is this possible
Thanks in advance

[edit]
Just to let you know, I also need these details kept in the table for future reference so I dont think I can use a query to do it.
I`ve attached a copy of the database with some example data in it if this is needed for any assistance.
I'm suppose to create a list of 20 clients and let 5 accounts be 90 days past due, 5 over 60 days, 5 over 30 days three of each of the accounts have a balance over $75. Then it asks me to create a total of all account balances so that the total amount of recievables can be known. The second part is calculate the number of days each balance has been outstanding.My question is this can you calculate dates in a table or can you only calculate in a query. I'm new at access so have patience with my question(s)

I red Tips section on your site and saw that default value can't be calculated.
