I hv a access mdb which contains one column as "duration", data format as hh:mm:ss, e.g. 00:02:20 - 2 mins 20secs.
How could I calulate the average of the duration?
like sum of all duration fields / the ttl no of records.
Hi,
I need to calculate an average waiting time for patients waiting to be seen in an A&E dept between two dates.
I have calculated the total waiting time for each patient with the following formula
Total Waiting Time: Format([Time Arrived]-1-[Time Left Department],"Short Time").
Any help much Appreciated
I'm new in access I working on DB for my company equipment
I used tables and queries and reached to the following query
Query name (02-By Project)
KSC_NO From_Project To_project Date_of_Trans
K-01-037 52500 12013 02/14/2014
K-01-037 12013 52500 03/31/2015
K-01-037 52500 12013 04/07/2015
K-01-129 52500 12013 03/03/2015
I want to make query to give me the following
KSC_NO IN_Date Out_date Duration (months)
K-01-037 02/14/2014 03/31/2015 13.6667
K-01-037 04/07/2015 Today 0.0333
K-01-037 03/03/2015 Today 1.2
Is that possible?
what is the best way to record durations, not time?I want to have a table that records charging data such as below:
startDate
startTime
Duration
(hh:mm:ss)
15/04/2012
12:00:00
13:00:00
In this example you can see we started charging the device at 12pm on 15/04/2012 for 13 hours, from this I will be working out the endDate/time using dateAdd etc.Do I set the duration field up as a dateTime and if so how do I avoid the DB thinking that the field is a time and not a duration, meaning that the endDate would be 1pm on the 15/04/2012 instead of the correct 1am on the 16/04/2012?
I want to calculate decimal hours duration taken for a job starting before and finishing after midnight.
I have something that works but it seems cumbersome.

I'm trying to understand loops but I'm not making any progress. I'm trying to write a loop to calculate the average of the past 10 Values including the current Value. This is what I have so far.There are also Fields for "Date" and "Time" if that is useful.

Dim index As Integer
Dim RollAveTotal As Long
Dim CurrentValue As Variant

I am building a database to enter staff phone statistics. As an example my fields would be - Name, Date, Staffed time, Available time, Aux time and then calculated fields to show the percentage of time i.e %Aux, %Available etc.
My problem is the formatting of the times entered as they are duration not time. Say staffed time is entered as 08:00:00 for 8 hours and Aux time 03:57:21. The only format I can see to suit is date time but then Access takes these entries as 8am and 3:57am is there a way to change this to work as duration hh:mm:ss?
Currently using a lot of Power Pivot Tables which in part calculate "averages" - but when the data comes form a Query that contains a calculated field using the iff() funtion such as: Outcome: iff(Status = "P", 1,0) we end up with a lot of zeros that create a problem in calcuating a true average. In the following example 2,3,0,1,0,0 the average is "1" but if the zeros were blank the average would be "2" because the blank cells would not be counted.
Is ther a way to have something like: Outcome: iff(status = "P",1,"blank") but what I want is ether 1 or a blank cell, NOT TEXT. If we use "" for the false outcome we still have cells that look blank but are in fact text cells and are counted in calculating average.

View 1 Replies View RelatedI have a report that comes from a query with multiple expressions. The expressions look something like this:
IIF([TimeArrive]>[TimeTriage],DateDiff("n",[TimeArrive],[TimeTriage])+1440,DateDiff([TimeArrive],[TimeTriage]))
This works great and my report gives me my columns for each expression in minutes they way it should. Now here is the question...is there a way to insert a text box for each column/expression so I can calculate the Average for each column/expression?
i.e. I want the report to show the average minutes of Expr1 and Expr2, etc at the bottom of each column.
Is there any formula or any way to calculate moving average on access? What I need is to calculate a value based on data from the past 3 months:

I obtained data for earnings by industry for men and women over time (5 years). I developed crosstab query that showed the average earnings for men and women for the 5 years.
Now I want within this query to calculate the differential between men and womens average earnings and calculate a percentage within this crosstab query. I tried to use Expressionbuilder with little luck.
I found the attached example a while back (can't find the site again though ) and it calculates a moving average. I've hacked out the parts I need for my own work and I can create my moving average query without an issue.
However, I need to extract the MA data into a table so planned on using append. I kept getting type errors so I tried make table to see what type it was creating and it appears to be Short Text rather than a number.
I've added an extra button and Make Table query to the example.
As far as I can tell from the code, the moving average value when calculated is a Single. However, when I write it to the table, its a Short Text.
How do I make the created Table use Number Type for my calculated moving average?

I want a query or report to give me the average entry time per record. Something like: Average time between orders 1:25 (one minute twenty five seconds)
I have a query with the fields dtDate (Date/Time in Short Date format), NC "Number of Chats" (Long Integer), and TCT "Total Chat Time"(Date/Time in hh:nn:ss format) from tblChats. Each date will have multiple NC and TCT values. This query is totaling them by date with the following SQL.
SELECT DISTINCTROW tblChat.dtDate, Format$([tblChat].[dtDate],'Short Date') AS ChatDate, Sum(tblChat.TCT) AS SumOfTCT, Sum(tblChat.NC) AS SumOfNC
FROM tblChat
GROUP BY tblChat.dtDate, Format$([tblChat].[dtDate],'Short Date')
HAVING (((tblChat.dtDate)>=Date()-7))
ORDER BY tblChat.dtDate;
The query works fine. Now my question.
I would like the query to figure the average time per chat for each day.
Could this be done without VBA? Any ideas??
Thanks.
We sell products out of vending machines and once in every few days (time span between readings may be different every time) read data from the machines using flash drive. Each reading from all machines produces an Excel file:
Reading_Date | Machine_ID | Product_ID | Amount_sold
2008-04-08 | 1 | 1 | 26
The only date that we have is the day on which the data has been read and this tells how many sausages were sold from the date of last reading till the date of current reading (after each reading counters are set to zero).
The problem is to get average amount of product X sold from machine Y on every calendar day. For a total rookie like me it seems like creating another column that would divide the Amount_sold by the number of days between two consecutive readings and put this average amount for every calendar day between these two readings. May it be done this way? How? Another way? How? I would be very grateful if anyone could help me and explain the solution in an accessible way.
Basically, I get daily reports from the client and the AHT and ACW values come in seconds. I've recently added code to the query changing the data to nn:ss which works perfectly. Below is some info:
tblTelephony
[AgentName]
[Calls] (number of calls answered)
[AHT] (in seconds)
[ACW] (in seconds)
[Code] ....
The above code works very well, where I'm stuck is in the attempt to average the fields [AHTMinSec] & [ACWMinSec] by Agent in a report.
Using [AHTMinSec] as an example:
I have the daily values for each agent [AHTMinSec] in the detail, Avg([AHTMinSec]) in the Agent group footer showing each agent's average, Avg([AHTMinSec]) in the Team group footer showing team averages and Avg([AHTMinSec]) in the report footer showing the campaign average including all teams. When I run the report the details are hidden providing each agent's average, the team average, and the campaign average.
The report worked just fine until I converted to minutes with the above code. Is there a reason that I'm getting an error stating that the calculation is too complex? I've done enough research to determine that the db can't Sum in order to average...
Hello,
I,ve made the following date fields in a form: begintime, endtime. I've also made a field Diff that calculates the difference between the two by the code : Diff = Format([begintime] - 1 - ([endtime], "Short Time").
Bij this code you can calculate the difference even over night.
But now I've got to calculate the part of the time someone worked between midnight and 06:00AM if that person indeed worked in those hours.
e.g. someone started at 16:00 end ended at 03:30. The part of time I need = 3:30
e.g. someone started at 01:00 end ended at 11:00. The part of time I need = 5
How can I accomplish this? I hope someone can help me because I'm :confused:
Thnx Remco
I have one table, Leopard Test Scores 2007, that has only two fields, employee and TotalSeconds. The totalseconds column has a "Number" data type with Long Integer. All entries in this column represent the number of seconds and individual spent to take a test.
All I need to do is calculate the total minutes for ALL records in this table for a report. I want the total to come out in this format: HH:MM:SS - so I've added the following three fields to my query:
Hours:[TotalSeconds] 3600
Minutes: ([TotalSeconds] - Hours * 3600) 60
Secs: ([TotalSeconds] - Hours * 3600 - Minutes * 60) Mod 60
However when I add those three fields to my report, I get an "enter parameter value" for hours and minutes. I must be missing something? any suggestions??
i have 3x time fields in a table i.e time received, time started, time completed i need to accurately caculate the time between time received and time completed. whenever the time goes past 00:00 it seems to add 24 hrs to my calculated time is there a macro or code that i can use to rectify this problem?

Is it possible to generate a query that can calculate the 'TotalMins' that an event covers our peak times?
I.e. Our peak times are 0700 to 1000 if we have a start time of 0600 and a finish time of 0900 is it possible for the query to work out that we have covered 120 mins of the peak period?

The below function returns correct time difference between workdays. However, it is excluding Saturday as per the code.
It is calculating 06:30 am to 22:00 pm time for weekdays but I also want it to calculate the time from 10:00 to 13:30 on a Saturday.
I am trying to use the NetworkMinutes function to achieve this. However, there is a problem getting the time for Saturday.
Code:
Option Compare Database
Option Explicit

I have searched the forum for this answer but no luck. :(
I'm trying to calculate the amount of WORKING time between two dates in an Access database. At the moment i am just subtracting one date from another but this gives me all of the time in between including weekends and evenings.
I need this time to be calculated in hours.
In Excel i know there is a NETWORKINGDAYS function which does something similar but with days rather than hours.
At least if i could get the working days i could then convert it into hours.
Please help!
Hello:
This is for the purchasing guy at my client's office. He has 9 vendors he wants to track their on time delivery performance. The data comes from the purchase order tables in his accounting software, to which I've linked via ODBC.
So far so good. I've created a query to pull only those 9 vendors from his total population, then ask for the date range to query by date for the date range (start and end date), and use an expression to calculate the difference between the date wanted and date received so he can tell if the delivery was on time or not. (ex: date wanted: 3/10/06 date received 3/13/06. 3 days difference = late delivery)
The twist is he wants another field so he can mark whether he considers the delivery late or not depending on extenuating circumstances he keeps locked up in his cranium, despite what the date difference results tell him. So, I created a combo box and he can select "Yes" or "No." If he selects YES, a value of 1 is written to the table in that field, if he selects NO, a value of 2 is written to the same field.
So, I need the query to group by vendor, count the total number of entries for that month by that vendor, count the number of "1"s and express that total as a percent of total deliveries.
To summarize, vendor A had 8 deliveries, 5 were on time, meaning he had a 62.5% delivery score. Vendor B had 10 deliveries, 7 on time, meaning a 70% delivery score.
Sorry for the long winded explanation, but perhaps someone can assist. All help appreciated.
