Tables :: Calculated Fields From Two Tables / Based On Relationship In Third Table
May 29, 2014
I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.
I am great with Excel but not soo much with Access 2010. I Excel, what I needed to do was very simple but duplicating what I did in Access is not soo easy.I am trying to calculate billings for FSA & HRA. I have set up one table with all the data. I want to add columns to the table to calculate:
1. Is there an account balance-excel formula: 2. If the account is still active 3. If the plan year run out is "active runout" or "runout over" 4. calculate each account type with a rate *count of FSA accounts = total to bill
Here are my excel formulas that for the life of me I can't get to work.
I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?
I have attached a zipped excel workbook to best describe what I'm trying to do. I have table1 and table2 and I'm trying to write a query in access to get the output as shown in the workbook. I'm having hard time getting this right. I would appreciate your help if possible. Tks
the table 2 is the source of a form that will let the user change the numbers. table 1 should change Date1 and Date2 Fields based on the two fields (3months) and (6months) if i want to make a lookup wizard it should be changed manually and if i make a calculated field i can't find other tables in the expression builder
I have a form that users can input data into and based on that data it runs a query and generates a report. These reports can be different based on user entered data on the form. My issue is within the report I would like to sum certain fields. The problem with trying to sum theses fields is that they show up on each row so I have hidden duplicates but when trying to sum the field it still trys to count the hidden duplicates thus giving a value that is of no use.
I have tried many methods to sum but one of the problems I continue to run into when I create a text box and build an equation and reference the field I would like to sum is when the report runs it is asking for a value to be entered for the field I am attempting to sum. I shouldn't need to enter a value as I am trying to obtain the value.
Is there an easy way to auto-populate a Junction table [in access 2010] given the following two tables with a many-to-many relationship for Tasks? The two tables are
I understand right off the bat if you're reaction is "don't duplicate data!!" -- mine would be too (don't fret, I know my normalization).
I've linked a table in my db to my Global Address Book in Outlook 2007 and, upon entering an employee number as a new record, would like to verify that the number entered is listed in the GAL and then pull in the associated name and location info.
The key is that I don't want this info to rely on the GAL going forward. For example, if an employee leaves or is no longer listed in the GAL, I don't want to lose the employee info (past data is needed for audit purposes). Note: I will be creating a report later to show if there are discrepancies between the GAL and my table, but that's another story...
So, what would be the best auto-fill options in Access 2007?
is there any way to put into the calculated field (in expression builder) conditions? What I need is something like
Sum If (Table1.Field1="Y" And CurrentTable.Field2=Table1.Field3)
I means sum how many times there is "S" value in the field1 Table1, but only for records where the field3 in Table1 is equal to the value in the actual table in Field2 (in the actual row).
I want to use an expression to compare 2 dates and calculate the date of the last set of accounts for a company. The user will enter(DD/MM) of the company year end e.g. 31/12. I then want to compare this with todays date (in another field) to ascertain if the month has already passed in the current year and hence calculate the last year end. i.e. If (current month>company month end), year end date is DD/MM/YYYY (where YYYY is taken from today's date), year end date is DD/MM/(YYYY-1). I am not a programmer and although I understand database theory (from the teaching perspective) I am not expert in developing databases.
Is there anyway to turn off the rounding function in calculated fields - I need to divide a currency amount by a whole number to calculate the number of full coin bags that will be needed (bags contain different totals according to the coin value) - a whole number.
Then the result is used to calculate how much loose coin will remain.
But regardless of the field type and/or the format, the number rounds when I reduce the decimal places to zero. I need the result to be the whole number and to calculate as the whole number.
I am trying to get an average from several numbered fields, which some may occasionally be blank.
=Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0)
I get an error message that says "The expression =Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0) cannot be used in a calculated column. This is a hypothetical expression being used.
We have our access database with a bit of a messy structure?
We use our database to record sizes of our product. I am hoping to improve it by adding the items we have in stock to prevent manufacturing more.
Basically our main database called "Make & Model 1" has a list of various makes and model numbers, each model number lists various information needed to manufacture a replacement part.
Customers order the part and these part details are entered into a table called "Order Detail" What I would like to happen is that when the details are entered a calculated field adds the data entered to a text string. I need to match the text string to the same text string in a table called "stock" as there could be one part that matches hundreds of models.
Basically the "profile" "Colour" "height" and "width" make the string and this is what I need to match and tick a box / populate the number of items in stock. Eventually I would like this to reduce by the amount ordered but lets do one step at a time.
I have calculated fields on my tables and used zero values as default to show totals. But when I view my report, all the zeros appear. Don't want those zeros to appear on the report.
The interface being used is a main form with various tabs and a subform on each of these tabs.
There is one field ('max power density') in my database that is calculated using 'Max Rated Power' and 'Cylinder Capacity' however these are in different tables and subforms. The 'max power density' and 'max rated power' are in table and subform 1 but 'cylinder capacity' is in table and subform 2. Is it possible to keep them in separate tables/subforms and still calculate the field?
I have a table with all my contacts. Manufacturers, distributers and outlet shops. I want to be able to make relationsships that show which manufacturers sell to which distributers and outlet shops, but at the same time I also want to be able to see which manufacturers are being sold by a particular outlet shop or distributer.
I am reading everywhere that you need to make a table to link the 2 tables together for every one relationship you have and this I understand. Most of the time it is relations between 2 tables that you want to establish. But in this case all these companies are in the same table. Can I still make a many-to-many relations ship between different items that are all in the same table using one single extra table that holds these relationships?
I am in the beginning of setting up a database and have NOT messed with multiple tables. I just want to make sure that I am setting up the tables as well as the relationships correctly.Here is what I currently have, 4 tables and they are named. Employee, phone, radio and spotter. Employee table is where my primary key is located and I currently have a 1-to-many relationship between Employee and the others.
What I want to be able to do is to store information in the multiple tables from 1 form, which I don't think will be an issue and then at a later date be able to pull up information. EX.Thus being able to skip anything being put into the spotter table. Then at a later date be able to pull up only the select information I originally put it?
Table 1: contains staff names and contact numbers Table 2: contains training above staff have been on or need to go on Table 3: contains pc and printer asset numbers of above staff
I used a form and entered some new members of staff in table 1. They got their auto numbers etc but when I open table 2 and table 3 those new members are not showing up in those tables. I have checked the relationship status between the 3 tables and the staffID from Table 1 is associated to table 2 and to table 3.
What's stopping the new entries from showing up in tables 2 and 3 ?
i am making a database from which i can calculate fuel required from one point to other in any particular type of vehicle.the problem is fuel from Pt A to Pt B is not same as from Pt B to Pt A.A sample table is attached as zip. qp.bmpis there any way i can cross refer field values with that of rows .
When I originally created my access database, I used a text field/column to connect 2 tables together. I would like to change this to reference the Primary Key/ID column instead of the text field.
Is there an easy way to go about doing this? My original thought was to create some vba code to replace the data in the column of the sub table with the autonumber in the primary table but I cannot figure out how to do it.
Basically in my order details table i have the following fields
Product Unit Size
At the moment i have the Product field with a dropdown that gives me all the products from my ProductT. But once i choose the correct product in the unit field it gives me all the possibilities of every product not just the units associated with that product. ie
ProductT Grasshopper Box1000 Adult Grasshopper Box1000 Subadult Worm 10pz Big
When I select the grasshopper product and move on to the unit field i also get "10pz" option but this is not a product available.
How do i set up validation of the fields Unit and size based on another fields data?
I've learned the hard way about using calculated fields in a table. I used on while building in Access 2010 for users that will be using Access 2007. Once my testers pointed out the error message, I did some research and realized my calculated field was the problem.
So, I created a query to replicate the calculation, deleted the offending field from the original table and redirected everything to point at the new query vice the original table.
However, my testers are still receiving the error about needing version 14 to access that table. There isn't a calculated field there any longer, but they still can't access that table. Did that calculated field put some sort of taint on my database that can't be removed? I'm not sure what to do. Do I need to start over, so that a calculated field was never part of the database to begin with? If so, how much of my existing one can I reuse?
