Calculated Field Utilising Data From Previous Record
Sep 14, 2004
Somebody please help me!!!
I am creating a database that will record the details of approx 30 shops and will store information on Annual Turnover, Profit, Return, etc.
I need to create a field that will calculate the increase/decrease in annual turnover between the current year and the previous year.
So far I have created a subform that will show the last 12 years of data for the particular shop, but now I need to add a calculated field that will get the current years turnover and also reference the turnover for the previous year, i.e. the previous record., and display the result. The other thing that I will need to do, is to have this field not calculated for the initial years trading, so this field will need to be hidden in the first record.
Can someone please offer some advice on how to go about achieving this???
I have a table (tblStats). The user enters his current weight in a field named Wt. There are 2 other fields in the table named WkLoss and TTDLoss. These two fields are intended to be calculated. What I am trying to do is when the user enters his current weekly weight figure into the Wt field, I want the field WkLoss to get the user's weight from the previous record and place the difference in the field WkLoss. Also I would like to keep a total to date in the TTDLoss field.
So far this has been my attempt. Code:Public Sub setWeight()Dim rs As DAO.RecordsetDim Startval As DoubleStartval = 190Set rs = CurrentDb.OpenRecordset("tblStats")'Select records to be updatedSet rs = CurrentDb.OpenRecordset _("SELECT * FROM tblStats ") rs.MoveFirst Do rs.Edit'field to update rs.Fields("WkLoss") = Startval rs.Update rs.MoveNext'increment step value Startval = WkLoss - Wt Loop Until rs.EOF rs.Close Set rs = Nothing End Sub All I get is the value 190 placed in the first record and all zeros in the subsequent records. Also I don't have a clue as to how to get the Total To Date field to calculate.
Any help would be appreciated Thanks for your time.
I am trying to construct a crosstab that averages a calculated field from a previous query. It is returning a "Data Type Mismatch" message.
The field I am trying to average is a subtraction of dates to find total days. I assume my field is not a number so I have tried to wrap it in CDbl() to change the type.
The formula is
Code: CASE_DAYS: CDbl(IIf([Actual Close Date]-[Creation Date]>=0,[Actual Close Date]-[Creation Date],""))
I would like to build a query that has a calculated field, involving value from a previous record. I have five columns, Year (sorted ascending), InvestmentRate, StartingBalance, AnnualContribution, and InterestIncome.
The first row, being the smallest year value, uses a previously defined elsewhere starting balance, annual contribution, and interest income. This is recognized via an Iif statement and establishing the first set of values which the second row should use to calculate.
The second record, and until the end of the query, automatically calculates the new starting balance value based on the sum previous row record's starting balance, annual contribution, and interest income.
Furthermore, for the second record, and untill the end of the query, the InterestIncome is calculated value incorporating the second row's StartingBalance value (which is the product of the sum of the previous record's values).
This calculated referencing to the previous record is causing difficulties.
Access 2003. I was just wondering if there was any way to refer to a calculated field in the same query. For example if the first calculated field was - Total: ([Quantity])*([Price]), could you add another calculated field - Inc Tax: ([Total])*1.175. At present I am having to type the whole formula in the calculated field again which seems to work for some queries, but not for others, no matter how I fiddle about with the syntax. The other way is to create another query and refer to my previous query. Both these methods seem extremely cumbersome and I was wondering if I have missed something with referring to a prior calculated field. The query above is just an example, my query formulas are actually fairly long and for editing purposes it can be difficult to correct them.
How to fill values in a new record with data from previous record?
I've total 11 columns in a table and values in 3 4 columns are repeating for few rows before it needs to be changed eventually. I want to fill these rows with values from previous record.
I need a way to dynamically store a particular value in "field_2" of the CURRENT record depending on whether or not the value of "field_1" of the CURRENT record is identical to the value of "field_1" of the PREVIOUS record within the same table. The table is sorted on "field_1".
So, if the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is also "ABC", then store a value of "PPP" in "field_2" of the current record. IF on the other hand, the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is "XYZ", then store a value of "WWW" in "field_2" of the current record.
I have a report that will use these results to count only the number of records that have a "WWW" in "field_2".
Is this doable, maybe in a query somehow?
I should add that whatever the solution, it needs to be compatible with Access 2000.
I'm a novice with Access but I thought I would use Access rather than Excel to record fuel use for our vehicles because the reporting functions should be more powerful.
I have set up a table where I input date, vehicle, member of staff, mileage of the vehicle and the cumulative reading from the fuel tank meter. I thought it should be simple enough to calculate the fuel used each fill by taking the meter reading away from the reading on the previous record, but I cannot find a way of getting Access to do this.
I have still not solved the problem wich is doing my head in!!! In the following DB I have the "frm1" wich the value of the first record for "Value1" is 10 when I pass to the second record Iwould like to show automatically the value 10 in the field "Value1" this for all the records untill I change toa new value so from then on it will show the new value. I believe is the Dlookup function, but I have not find the way to make it work. I must be thick but I need your help!!!!! Thanks
I need to add two previous record fields together in a query. I have attached a picture to illustrate.
The "StudyYears" filed is the primary key of the table the data is being pulled from. The zero's are placeholders for the sum of the previous record's data.
Hi I need to copy some data from last record to next(New record), when a user clicks a button on a form. I don't want to copy all the data.
An example would be booking in items from an invoice: Company would be the same Invoice number would be the same Product code would be different quantity would be different
Hope this makes some sence, and i'm not being stupid:rolleyes:
When I click my command button that says, "New Record", I want it to go to go to a new record and populate the field "Town" with the value in the previous record.
e.g. ClientID on last record is 150 and has Town="London". Click "New Record". New record created. Town field on ClientID 151 has Town="London".
I'm trying to create something like an online banking view that shows the running balance as each transaction occurs. I have tblTransactions with fields AccountNumber, ItemDescription, and TransactionAmount. I'm trying to create something that shows these three fields and a fourth field with the running balance.
So if I initially deposit $100 it will show the first record with TransactionAmount = $100 and RunningBalance = $100. Then the next transaction will subtract the Transactionamount for the new record from the RunningBalance from the previous record to get the RunningBalance for the new record. So if I make a purchase for $2, the AvailableBalance for that record is $98. Is this possible with a query? Here's a picture to describe what I'm talking about ....
I am creating a form to update a table of records. The table represents purchase order assignments and I need the next sequential purchase order number (as per the order number from the previous record) to be displayed in the new record (order field) on the form.

Table: Orders Field: OrderNumber
Form: Manual Orders Data Entry Field: OrderNumber
Form was created using wizard.
Information I would like to display is the content of OrderNumber Field +1.
Month and Days are pulled from a table called Calendar. How do I get PreviousMonth to display the Month from the previous record?
I was looking at a ranking formula, and it seems like it compares the field to the previous one, but I am not sure how to apply it to my situation. The ranking formula I was looking at:
(Select Count(*) from Data Where [ProductA1] > [Data1].[ProductA1];)+1
I have a query to bring in values, I need to select 2 rows of data but the criteria is as such:
x= starting value on form
now the row of data must match the following criteria previous row to current row(ref temp)<=x And Current row(ref temp)>xnext row to current row(ref temp)>=x And Current row(ref temp)<x
I have dealt with SQL before but how to do the above.The isolated 2 rows of data will then go into unbound boxes on a form from which I will do intercept and gradient calculations.
I have a subform that is embedded in a main form. The database itself is a few years old and so I think redesigning is out of the question. What I am wondering is if there is any specific code that can go into the tables themselves and populate the form based on the previous record. I would like for the Transfer to Rehabber fields (To and Permittee) to be duplicated on the Transfer From Rehabber fields (From and Permittee) on the next record. Do you think that there is code that will be able to achieve such a thing?
I'm trying to update an imported table from an excel spreadsheet with missing details. The table's records are in order so I just need to fill in a blank field with data based on the previous one as shown.
ID Name Location 1 Bob London 2 Larry 3 Harry 4 Jerry Glasgow 5 Paul 6 John Southampton
I need to fill in the location blanks simply with the last location details, so records 2 and 3 with London and 5 with Glasgow. Is this easily done or would I need to pull all the data into an array and work on it there?
I've tried searching for an answer but haven't had any luck.
There is a form which the user fills in 8 fields and saves it. Once saved, a new record opens.
However, I want to modify the save button to save the previous record and display a new record with only a limited no of fields to display from previous record, say 4 fields display from previous record, and the user fills the remaining 4 and saves it. Thus, the save cmd should continue to display 4 fields from the previous record.Already tried below code for save button but it displays all data of previous record as it is, doesn't display blank space for combo.118 and text2
The GetDates Command BUTTON should generate the red data above, like:
Private Sub GetDates_Click()
Go to a new record Go to the field App_Freq and fill it with: Copy/paste the data from the field of the same name in the previous record Go to the field App_Date and fill it with: data based on this calculation using the PREVIOUS record fields: App_Date + App_Freq (which are days) Go to the field Action_Date and fill it with: data based on this calculation: App_Date (of current record now filled out - step above), minus 7 (days). End Sub
That's it!
All the dates format is set to medium date. An error message should come up in case App_Freq is empty, for example
Also note that the data can be manually changed at any time and should not revert to its last calculation. The button only generate data into a new record.
I have an access form that needs filling in daily by various people.
It's to document changes to a website and I currently have a combobox box set up for the various sections to state whether they are AMENDS, REVERTS or NO CHANGE.
I have set conditional formatting to then highlight these sections but am also trying to get it to work so that if the user chooses "NO CHANGE" then the data for that field copies over from the previous record.
I have set this up in the AfterUpdate code for the combobox, but nothing is happening, not even an error....
Code: Private Sub COMBOBOX1_AfterUpdate() If Me.COMBOBOX1 = 3 Then Me.[FIELD_TO_CHANGE] = DLookup("[FIELD_TO_CHANGE]", "tb_TABLE", "[ID]=Forms![form_FORM]![ID]-1") End If End Sub
(Where 3 is the value of NO CHANGE in the combobox, and FIELD_TO_CHANGE, tb_TABLE and form_FORM being the names of the various elements)...
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:
If I have four date Fields in a query, Astart, Bstart, Cstart, and Dstart and want to have a calculated field to find the latest date for each record how would I do that? I have tried things like:
My situation is this. I have 3 tables that I have imported from my mainframe system, between these 3 tables I have the data of product code, description,supplier code, supplier name, order method, and ABC code.
I am trying to create another table that I can capture daily Out Of Stock data for products.
What I would like to do is to enter the product number in the first field of my new table, and then the remaining fields will auto populate with the correct details based on the product data stored in the parent tables that I have imported.
