Help With Grouping Items And Calculating Averages
Oct 28, 2007
Simple query for the right person!!!
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
Split Billing | 4 |27/10/07
Split Billing | 8 |27/10/07
Split Billing | 9 |27/10/07
Split Billing | 1 |27/10/07
Split Billing | 4 |27/10/07

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.

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.

I have groups that run horizontally down my report. Is there a way to group items vertically on the report based on the horizontal information.
For instance I have a client list with the total of the transactions they made. Then I would like to run in the same row the breakdown per quarter showing all 4 quarters in the same row as the client name, but separated into columns for each quarter.
Any help would be greatly appreciated
Thank you!

I have a table which lists rentals, all have start/end dates and a rental fee p.a.
I want to query this table to show rentals that are effective for any part of 2 dates, [Enter Start Date] and [Enter End Date]. The purpose of this query is to calculate rental income between these 2 selected dates.
Now I have this much working, but I want to group all the figures by month, in order to produce a graph to view the rental income by months.... this bit has me stuck....:confused:
How can I group all these records, when I only have 2 dates... for eg, start 01-01-06 and end 31-07-06...
I want to see figures for Jan06, Feb06, Mar06...July06etc... rather than just a single total figure for the entire period...
Any ideas?
Help! I'm completely stuck here and have spent hours searching the internet but haven't found anything suitable...

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 just want to know how to manage items in set and individual item. Suppose my product list are
individual items = A,B,C,D,E,F,G,H,I,J,K
and 5 pc set = A,B,C,D,F
and 3 pc set = G,H,K
How should I design the table. Previously I designed the table for individual items and whenever orders for set is placed user had to enter individual items with quantity.
E.g. order is for 5 pc set = 3000
A=3000
B=3000
C=3000
D=3000
F=3000
Now I need to just say 5 pc set and it should be automatically populated. And also if order have combination of individual and set items.

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.

I'm not sure if this is the right forum. If not let me know and I'll move the thread.
Table 1
Date
Measurement A
Measurement B
Measurement C
Table 2
Table 1 ID Link
Data 1
Tables are linked 1-to-many from table 1 to table 2 by ID.
I would like to average the Data1 data per Table1 ID and report it with the Table 1 Measurements.

I am designing queries to return averages for quality test data.
I have this query that functions as I want it too [URL] .....
It returns the averages of all the values received for different tests for a lot number (the lot number criteria should be filled out as well)
When I want the query to be more specific and average only certain box numbers in the lot (that start with the prefix PB") the query does not return an average for box numbers starting with PB but splits them up, showing an average for PB1, PB2 instead of combining the data for those boxes into a single unified average ...

I have created an invoicing system for a CD shop
There is a transaction table which has each individual cd sold as a seperate transaction. Each transaction has an order number, so there can be more then one cd sold per order, but they all still have their own record in the table.
im now invoicing each order by mail merge based on a query that finds all the details on every transaction but wht ive found is that the mail merge puts each transaction onto a different page even if its from the same order number as another.
does anyone know how to group each order in the query so that all the items in one order come in a single invoice?

Question on grouping within Access Reports:
A simplistic view of the report I'm trying to generate is as such:
Company Name - Company Description - Employee
I am grouping by Company name, and I am hiding duplicates of Company Description because they can be long. I also have the Company Description as Allowing to Grow.
The problem is that the first record gives the company, the description, and the employee name on the first line just fine, but the second employee name won't be listed until the Company description ends. When the description is about a paragraph long, the other employees look very seperated from the initial record.
Any way to fix this?
