- In this video, I will show you how to use calculated query fields to perform basic calculations on the fields in your table. We will also see how to use form footer totals.
Harold from Las Vegas, Nevada (a Platinum Member) asks: I'm trying to figure out the value of my inventory. I have the cost of each item and the quantity I have on hand. How do I go about calculating the total value of my inventory?

Silver Members and up get access to an Extended Cut of this video. I will show you how to use calculated table fields (and we'll talk about whether or not you should use them.) We'll also take these calculations over to a report. I'll show you how to use a running sum, and how to create a report page footer total.

DUUUDEEE!!! I've been on this one homework problem for over 2 hours trying to get this mashugana database to calculate!! Thank YOU!!!!
Your videos have been super helpful! Since starting as a Sales Support Admin last April, I've built two databases for our Sales team. The results have been highly praised and the time to develop the DBs was reduced because of your videos. Thank you!
Glad it was helpful!
I'm thankful that you have an entire series based on ACCESS.You have helped me so much and all i can say is thanks you men.Appreciate it :)
Glad to help!
Greetings! I really enjoy watching and re-learning from your tutorials. I've been away from computer languages/applications for some time now. My 5th or 6th career change has me back into the game and remembering a lot of what I've forgotten. I'm thinking about becoming a member to enhance my SME status as a CSA contractor. As I build a rather large DB I'll add your resources along with others. I look forward to seeing more of your tutorials. Cheers!
Glad you like the videos. Cheers!
Performing calculations in a query and performing footer total in a form is a straightforward process. I like working with queries. It is helpful.
Glad it was helpful!
@@599CD Thank you.
As soon as I heard "tribble bait" I got way more focused. Nice job
👍 Simply the best way you explained Access query and formulas
Thank you
Very useful and great information. Thanks a lot for guidance.
Most welcome!
Thank you very much for your help. I was struggling with getting the number sign to show for the calculated fields now its working.
You're welcome!
I was able to have a query do a calculation as you describe- thank you! However, how can you update a table field with that calculated query? For example, if a record shows a customers name, a qty of a particular item purchased, to show the total in a table field? If i try to add a lookup field from that query, i get an error.
How to store on the table calculated value in the forms like control number or reference number?
Thanks the good explanation
You're welcome!
Very useful thanks a lot
Welcome
Hello, I was trying to calculate total(or rather sum) of fields, some being empty (null). The problem is that the total can't be calculated without having a value in one of such field. zero value gives a total but i dont want to use zero in my fields, i just want it to be empty. is it possible to have some empty fields and still get your total?
To be more precise:
total: [field1]+[field2]+[field3]+[field4] ... and field3 is empty

Thanks Richard, when its not good to create a form from queries? Joined table queries causes problem sometimes for instance
I only recommend creating forms based on queries when you are solely editing records from one of the tables in the query. If you have calculated fields, for example, quantity times unit price, and that's a non-editable field, then you're fine. However, you don't want to have fields that you can edit from multiple tables because that just asks for trouble. I actually have a video on this topic coming out pretty soon, so good question.
Bit of an unrelated question but I created a calculated query. When finished, I unchecked the "show" box for the fields I did not want to see when it runs. Is there a way to bring them back and show again? I wanted to see them in design view again. Thanks!
Uncheck the box.
how can I make a summing process for aspecific values such as a some value from table products and their prices from pricee table. or any process as this

Hello Richard, how do you add a calculated field in query design for items in different tables?
Just specify the table name in front of the field name. CustomerT.FirstName, for example. I actually have a video on this coming out soon for beginners.
Thank you Sir. Love from China.

hi, i created a query, but i have no idea how to bind this table+query with c# datagridview. i have no experience in it but i do have to create this project. can you help me with that? what should i do to bind the table with total column in it with datagridview???
Sorry... C# is not my jam.
Hello sir, Does the extended cost field also appeared in the ItemT?
No. Why would it? It's unit cost multiplied by the quantity you're purchasing.
man you are a exam saver
I get that a lot. LOL
I wonder the correct way to change unit price while maintaining all the historical unit prices on official reports for IRS and/or display forms showing customer journals or ledger entries.. what's the standard solution calculation with dates or a make table..? Cheers ..
You need to copy the product price to the order details table. See the extended cut for 599cd.com/Invoicing

How to get access to the Queries Section, I don't even see this under Create?
It should be there. What version of Access are you using?

haha I got it. My access is Danish language and Querie is called something different. Problem solved
Greeting ..nice tutorial ...i have question how to get AVERAGE 3 item in one table..
example:
table Student, field:
- Math
- English
- Science
Usually I finish this problem with -> total: ([Math]+[English]+[Science])/3
but i want use-> AVERAGE(([Math]+[English]+[Science])) that still problem and not yet solved, maybe you can help me...
thanks
Average doesn't work that way. You need to add up the 3 fields and divide. Average can only be used in the form footer on a single field (Avg or DAvg).
@@599CD thanks for your answer ..
Sir How i do This? Sir i want to have a calculated field, it also a calculation and i can also add the value of my own
Sir Please Reply
I don't understand
Hi, Thank you for all of your reply. Let me explain my situation. I
have a receipt to charge customer & received payment (No more
invoice). I have 4 items to be charged, and each receipt charge one
item only. 2 items have a fixed rate (will be revised within a period)
& 2 items without fixed rate. So when I select the fixed rate items,
the calculation of [itemVaule} * [PayPeriod] can be workable. But in
the items without fixed rate, I hope I can put the [Total amount] by
myself. In addition, I need all the above to generate a report. Hope
the above will give all of you a right director to think of my
problem. Thank you again for your help.
I had tried to calculate in query by using an expression : [ItemValue]
* [PayPeriod], but the result is can't edit the [TotalAmount} field in
FORM.
When I had tried to use an unbounded test box in FORM and make an
equation in ON CURRENT EVENT - Me.TotalAmount = Me.ItemValue *
Me.PayPeriod, it can edit the [TotalAmount] field, but it can't save
it, I need the [TotalAmount] to generate report.
I have a table as follow:
Empl Dates Hour Sum of Hours
Emp1 date1 8
Emp1 date2 5
Emp1 date3 4
Emp2 date1 1
Emp2 date2 3
Emp2 date3 5
....
How do I sum hours for employees and place the sum value on each rows of in MS Access Query and by not using SQL or VBA? like
Empl Dates Hour Sum of Hours
Empl1 date1 8 17
Empl1 date2 5 17
Empl1 date3 4 17
Empl2 date1 1 9
Empl2 date2 3 9
Empl2 date3 5 9
and so on.
