I've searched hours on the forum but with no luck. If there's anyone out there who can help me would be very much appreciated.
The calculation in Excel is very simple but I am unable to replicate in Access. Please don't confuse this with FIFO calculation as it is purely Weighted Average Cost method based on Buy unit prices i.e Sale unit prices are not required as it will sell at the Average Cost of the Buys upto the point of Sale.
i.e.
Buy 100 @2 = 200
Buy 100 @3 = 300
Total 200@ 2.50 =500
Sell 100 leftover will be
Total 100 @ 2.50
I am attaching an Excel S/sheet which shows the Calculation of Stock ABC and the Average Prices (which is what I am trying to achieve). I have also attached an Access Dbase with same details but without any calcs as whatever I have done I am unable to achieve my result.
I'm having a problem getting a report textbox to display the average value that I want.
Background:I have a DB that tracks student grades. The course is organized into blocks, with several tests in each block. Students can take the same test multiple times, in cases of failure, or if they get rolled back in class. The DB tracks whether or not each test is a retest or audit.
The tests are also weighted. For example, the Geo Quiz could be worth 10% of the grade for a block, and the final exam 90%.
Goal:My report needs to display the class number, student name, block, test, and associated scores; it needs to show the total grade for each block; and it needs to display the student's average grade across all blocks. I need to be able to generate the report at any point in the course, not just after all blocks and tests have been completed.
Setup:Since I want to display the assigned grade, but calculate the weighted grade into the block grade, I set up a query (qryWeightedGrades) to calculate the weighted grade for each test (e.g. Score of 98%, weighted at 10% of block, results in a 9.8 for the weighted grade). When it comes to calculating the block grade, I just sum the weighted scores.
In the report (based on qryWeightedGrades) I have the grouping levels set up for Class#, Student name, then Block; the test name, score, weight, retake info, audit info, etc. appears together on a row.
How to do, get the average of all the block grades. I can't get the textbox in the Student Name group level footer to average the Block grades in the Block group level footer, without getting an error. I've thought of creating another query that averages the block grades for each student, but how to incorporate that into the footer of the Student Name group level.
Here's an example of what I want the report to look like:
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.
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...
I have a calc'd percentage field in my query. This is a multi user app and the problem is that is can (and does often) happen that the numerator information for my calc gets entered before the denominator data and therefore the calc'd field shows and as an error.
I attempted to use a simple IIF statement to input a message rater than the error code but now the field will not format to Percent. It worked, I got the message to display and it calc'd the records that had data, it just will not display in percent format. It does let me set the format to percent, it just doesn't display and does not allow the decimal places to be set.
This was the line: CalcPercent:[Numerator]/[Denominator]
This is the new line: NewCalcPercent:IIf([Denominator] = 0, "Message", [Numerator]/[ Denominator])
I've tried to search for an answer and I'm sure it is going to be something simple that I've overlooked.
subtracting field B from field A. Field A has data in all records, field B only some. The 'only some' I get a result but the ones that have nothing in B I get nothing even though A has data. Both are currency and default is 0. How do I take nothing from something and get nothing you ask ?
This is the second edited section: I got the update query to work properly. Is this the best way to solve my problem?
This is the original edited section: For the problem below would it be possible to use an update query to update the table? Criteria for the termination_date field would be "is not null" payment_to_date Update to: field would equal DateDiff("m",[payment_start_date],Now())*[monthly_payment] Is it possible to use other fields in the table as part of the UpdateTo: calculation? I get an error when I try this.
This is the original question: I have a field in a table called payment_to_date that I want to always be populated with the current total of how much a customer has paid to date based on their monthly payment rate. I have a form for data entry into this table but once their account info is entered the first time their won't be any changes to the account unless they terminate the service so calculating from an event procedure on the form doesn't make sense to me (I am new at this).
I entered the following in a text box control source on the form and it works but the textbox is not bound to the table so it's not the right way to do it.
=IIf([termination_date] Is Null,(DateDiff("m",[payment_start_date],Now())*[txtpayment]),(DateDiff("m",[payment_start_date],[termination_date])*[txtpayment]))
The calculation from above is basically: If there is no termination date then the payment to date = the number of months between todays date and the date payment was started multiplied by the monthly pay rate.
Can anyone tell me how to keep the information in the table current for the payment_to_date field?
Hello everyone. I am very new to databases, may have bitten off more than I can chew, but I was tried of working in 4 different spreadsheets and decided to pull them all into a database so that I could get what I wanted when I wanted. Here is what I need to be able to do: In a table I have 3 different industries entered 5 different times. They all cover a Monday to a Friday. Each day for each industry I record a reading from a meter. I make a calculation by subtracting Mondays number from Tuesadays, Tuesday from Wednesday, Wednesday from Thursday and Thursday from Friday. This calculation gives me how much water each industry used each day, over 24 hours. Doing this in a spreadsheet was simple. My table has the Industry name, date, previous day meter reading, present day reading. I want to have the calc show in my query. How do I set up this calculation. Any help would be greatly appreciated. Thank you. I attached a sample database that contains the table and query.:confused:
My head's swimming right now so the solution to this problem may be right under my nose and I'm just blind to it.
I have a table with events, represented by an ID number, and the date/time the events occured. Each event is also attatched to a particular mission number. Looks kinda like this:
Mission EventID Time
Each Mission has different events like liftoff and patient contact, and I need to find the time between events for each mission. I'm trying to calculate the Time from inital call to mission end, from dispatch to liftoff, ect.
Do I need to put these times into my mission table as columns, Time1, Time2, Time3... or can I leave them normalized and still run calculations on them? :confused:
I'm trying to finish a query that calculates the time worked in the AM and PM, adds them together, then takes that away from the standard working day.
I've done everything else, but when I take the hours worked away from the standard day it always ends up with a positive number, regardless if they haven't worked enough hours.
I've looked through the forums and everyone is talking modules, but thats over my head.
How do I use fields in related tables to create a calc field? The wizard only shows me the current table's fields. Can I do create me desired field by manually creating the calculation and bypassing the wizard? Or is this another restriction of Access?
I want to create a calculated field that If the employment type is FT Hourly or PT Hourly it will have a pop up screen for the Hourly Wage to be entered. If those criterion are not met it nulls the Hourly Wage field.
If I put a calculated control on my form, I don't seem to have any way of pushing its changes to a field when those changes happen. Access can be downright infuriating at times. I've spent days just putting together a simple invoicing application.
My form is not based on a query like the northwind database, because that created such ridiculous and useless behavior with subforms that I couldn't. So now that it is based on a good old fashioned table, when I change a qty or price, the calculated "extended price" (=[qty]*[price]) field visibly changes just fine, but it never has an "after update" or "after change" event. Why would this be? How am I to save these bloody changes to an actual field in a table without using some grossly inelegant code?
I Have a table that I collect data for numerous ID's. One ID may have 5 dates that is was serviced. It is due to be serviced at set intervals which is calculated from the most recent service date. I'm calculating the next service date in a text box with the DateAdd func. =(DateAdd('m',[Cal Freq],[MaxCalDate])) with the MaxCalDate being a Max func in a different text box for selecting the most recent sevice date. I'm trying to update the [Next Due] field in the [Master Asset] table with the calculated next service date so I can do queries on items that are due service within a date range. If I do an Nex Due Expr1: in the queries to calc the next due service date then do a criteria on that Expr1: such as >=[Start Date] And <=[End Date] it states datatype mismatch? Is there a way to select a requested data range on a calculated type date/time? Or How can I update the [Next Due] filed in a different table?
I apologise for my ignorance, but I’m very new to Access.
I have a database of dates, that I need to analyse.
I have created a Form called "DateRange" with 2 date fields; Text1 = Date From Text2 = Date to Command1 = Preview Report
My Query has 2 fields; Slotdate = all the dates (show as 20051210) Actdur = Actual Duration (show as numbers 1 or 12 or -3 etc)
The SQL View is; SELECT slotapp.slotdate, slotapp.actdur FROM slotapp WHERE (((slotapp.slotdate) Between [Forms]![DateRange]![Text1] And [Forms]![DateRange]![Text2]));
I just want to calculate an average of Actual Duration So that my report displays the average duration between the date ranges.
Any assistance in this matter would be greatly appreciated

I have two tables. The first contains details of a budget holders money allocation for a given period, and the other tracks their spend on products over that period. How can I generate a query to calculate the total running spend for each user from the "budget spend table" that will be written into the users record in the "budget allocation table".
My aim is to show details of budget allocation, total spend to date and remaining budget for each user in an Order form / report.
Can anyone please advise me on how to do this or suggest another way of doing it. Any help would be greatly appreciated.
