Tables :: How To Make Calculated Field Based On Field In Another Table
Jun 18, 2014
Table1 contain Two fields (3Months) and (6Months)
Table2 contain Two fields (3Months) and (6Months)
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 what is probably a stupid question but I've been struggling with this one for a while. I have an ordering database which has an Orders table (containing Order ID, Date, Supplier etc) and an Order Line table within which I have a combo box for Product name, supplier, price, VAT rate, Line price etc. At the moment, I have the order line table as a subform within the Order form (run from the Orders table). The problem I'm having is the subtotal and total fields. At the moment these are in the Order Line table as I cannot figure out how to get these in the Orders table. In summary, can I make a calculated field in one table that calculates values from another table (linked by Order ID)?
I'm creating a database that keeps a track of questions and scores.
The questions in the database need to be dynamic and are changed frequently.
I have a scorecard table which keeps a record of scores and the applicable question at the time the record was saved. I need to do this because in 6 months time we may want to provide feedback. As the question may have changed we need to be able to refer back to what the question was.
I want the question field in my scorecard table to populate with the value in my question table.
I have tried a number of things including setting the question field in the scorecard table to a lookup based on the following query:
SELECT tblQ1.Q1 FROM tblQ1;
This works however only as a list or combo box. I don't want the user to have to select the question. I want it to auto populate, is this possible?
I am creating a database to keep up with the expenses for my art business. I have a table for Vendors with a field (Mileage) for one-way mileage that I enter manually (EX: 11.8 miles). Then I have a calculated field that basically just multiplies the Mileage field times two to get total mileage to and from my house to vendor location. (Total Miles) {The reason I want to do this this way right now is because I didn't keep up with my mileage this year and I am having to look up the distance from my home to each location)
Then I have a "supplies" table where I show the date, the vendor, the item, cost, etc, and I want to add a Total Mileage field based on the calculated Total Miles field in the Vendors table that will automatically populate based on the vendor of each transaction. I just can't remember how to make this work and I know just enough SQL to be dangerous.
Within my table if Field 1 has an answer of Self (from drop down), then, I would like Fields 6-12 to auto populate; however, if Field 1 does not have an answer of Self, then leave Fields 6-12 blank.
I am not quite sure how to lay this out. I am using Access 2010.
I have a main table which is autonumbered on unitid, I have another table which is linked via the unitid which holds items purchased for the main table, so the second table is a subform of the suppliers and will have multiple entries of the same unitid. What I would like to do is when an item is entered into the second table, check the main table to see if it exists, if it does populate the unitid field with the unitid from the main table, and if not exist create a new record in the main table with the next unitid number.
This in essence is what I want, bearing in mind that the tblinvoices is a subform and the tblmain is not open.
If ([tblinvoices]![Unit] = [tblmain]![Unit]) Then [tblinvoices]![UnitID] = [tblinvoices]![UnitID] End If
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?
I am trying to add some numbers together for a number of fields, of which at least one field will either be 0 or empty. I am trying to use the following formula in a calculated field in a table:
I have started work on a database to track the many (several hundred per annum) projects my company undertakes. A 'main' table lists projects, their fees, their key dates, their project numbers, etc. I have created another table for tasks. Each task is assigned to a project (via the project number), and may be 'open' or 'closed'. I have separated the tasks table from the projects table as there may be several different tasks for each project. It is also good to keep a record of the tasks.
I want to prepare a report from the projects table that lists projects IF they have any open tasks.
In my mind, this means 'If a task, with the corresponding project number, is open, put a 'Yes' in the 'Tasks open' field of the Projects table.'
Have a table with columns of data which I want to total at the end of each row. The Calculated Field does this simply enough but it only seems to be able to add whole integers? How do I get it to accept and add values to 2 decimal places?
i want to insert a calculated value of a e.g field6 (field4 * field5) in forms into the database table. by using expression builders in my forms. i have made that feild and on click it shows the calculated value but on filling in the rest of the form and clicking on Insert button does not update this calculated field but iserts all other fields.
I have a query with a Date field for EndDate (the dates for end-of-week, Fridays in our case) and another field for Sales (number of sales, not dollars).I want to add 4 calculated fields that represent weeks and have the Sales appear in the correct column (field) for that date.So I will have columns for 10 July 15, 17 July 15, 24 July 15 and 31 July 15 and I want the Sales for each record to land in the correct date column, based on the EndDate column. (The 4 fields is just for the sake of the example, I will actually be having dozens of these calculated date fields).I tried to do it by setting up the 4 calculated fields like:
10Jul15: Sales and then adding Criteria like: EndDate = #10/07/2015# It doesnt work.
My form has a button that has a calculated field on it (a dcount(...)). When the button is clicked, a couple of conditions are checked and if all is ok, it runs the vba code. If the tests fail, it returns to the form without running the code. All works correctly, except that the dcount number has disappeared. I finally figured out that it is now hidden behind the button. How do I bring it forward again programmatically?
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.
Hi, I have a query that contains the results of repeated tests on a number of persons. The goal of treatment is to get those test results below 50. I need to find, for each person, the period of time (with a start and an end date) during which their test was below 50. The dataset looks like:
Hello, Bit of a newby to all this. Am trying to use a text box as a calculted field. I am doing so using an sql statment in control source The sql stat is built and tested using build query and then copied and pasted from sql view)
I keep getting #name? as an error.
I have managed using dlookup of the same saved sql to return the required value (which works) but find it to be a bit slow and clunky so wanted to give this a go instead. If somebody can have a look at the query below I would much apreciate.
=(SELECT Sum(QryInout!CostExVATGBP) AS TTlCostExVATGBP FROM QryInout &_ WHERE (((QryInout.StockImportNoJoinToAll)=[Forms]![FrmSPurch]![ImportNoNew])) &_ GROUP BY QryInout.ProdType &_ HAVING (((QryInout.ProdType)="Freight"));)
Note that I have tried with and without the &_ and also with or with out the brackets..
I have a field in a table that is to be concatenated from two other fields, PolPrefix and PolNum. On a form I got it to show the full field 'PolicyNumber' by making the control source =[PolPrefix] & [PolNum].
But this doesn't update the field PolicyNumber in the respective table, and only shows it on the form. How do I get a concatenated field defined by the user into a table so that I can call that field other places in the database?
Hi. I have an Order form that is based on an Order table. In this form there are also a number of text boxes (not bound to table) with calculations, and one final text box with a deadline based on these calculations. Is it possible to filter this form based on the deadline? I can do this by making the form based on a query, but then again I'm not able to edit the information in the form.... Please anyone???
I Have a table with 15000 entries. This table lists components we use. This table is used to generate queries/forms. I have been asked to add a hyperlink to this table to link to a drawing of the component. All the drawings are in PDF and in the same folder. I am looking for a way to automatically update the hyperlink fields all at once. The Hyperlink will be in the format of servershareddrawings12345.pdfwhere 12345 is the component name from the table.
But there are a few small problems with the component names. 1. If the component begins with a B- . The drawing name will be all the characters except when there is a second dash in the component. So if the component is B-12345-678 the drawing name will only be B-12345. 2. If The component begins with AB, The drawing will be the first 5 characters regardless of what follows, e.g. AB123. 3. Finally for all other components the full component name will be the drawing name.
Putting the naming to one side, how to go about auto generating the hyperlink. I have posted this in the table section, but maybe this should be in another section like queries or VBA.
I am trying to create a table for income and expense [catergory] and would like the amount being entered into the [amount] field to have a negative or positive value on entering based on the category chosen.
so in my table I have
[catergory] which is chosen from a look up table ( which is either an INCOME or EXPENSE ) [amount] which is entered in the next field ( which has to return a positive or negative value based on the catergory choosen upon entering the data)
I would like to go one step further and indicate this negative value in red is possible in my FORM.
I (will have) a form which a user fills in to enter new data.
I have two fields,
"Branch" and "Branch ID" (Branch ID will not be on the form, just in the table)
Branch will be fed by a combo box with seven choices. I would like it so that when "Branch" is populated it autopopulates Branch ID with a code which relates to the branch, so for example
