Modules & VBA :: Subtracting Value On Current Record From The Value Of Previous Records?
Jun 5, 2013
I want subtrack a value on the current record from the previous record and display the result in text box in subform datasheet. This is done during data entry. The calculation works most of the time and randomly it returns the wrong value. I have the code in an after update event after I enter a number. Here is what my code looks like:
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 struggling with a query to evaluate current and prior record data. I have a query producing 5000 records. I need to group records by Case ID and compare current date record to previous date record to determine if a team and worker name has changed during the year. I need to count how many times a cases is transferred to and out of a particular team from the beggining of the year. i.e., On 1/1/2014-Team1 has an inventory of 500 cases.
During the month 25 cases are transferred into Team1 and 15 cases are transferred out of Team1. So on 2/1/2014 Team1 begins with an inventory of 510 cases. Throughout the year cases come and go from and to Team1 each month so need to figure out how to create a query to count each change. See attachment displaying how the data is listed and how I invision it to work with the In/out column counts.
Specifically, at the begginig of the year (1/1/14) for case ID 1003 you can see it belongs to Mary in Team1 for January and February. Then in March the case is transferred out and went to Joe in Team 3. So for Mary a "-1" is recorded as a negative count for that Case ID. If later in the year the case is transferred back to Mary a "+1" would be recorded. Respectively evaluated for each of the 5000 records to get a total count for each of the teams by Case ID throughout the year.
I've started with DLookup, tried comparing current month to previous month using DMax. It works as long as I only select one case ID used in a separate query but if I use the whole subset (5000 records) it fails. I can't figure out how to group each set of case IDs and then apply the query.
I have a table of customers who report trouble on their equipment. I would like to compare the date in the current record to the previous record to see if it occurred within 30 days. Can I do this with an SQL query or expression?
I want to get the datediff of the last returned date from vacation and the current vacation start date. But how to get difference from the previous record's date to this current record's date. I want to show date difference in an unbound textbox. I have a contiuous form which shows all vacation list of employees. It shows how many times he went vacations and when he went and when he returned.
btw, although values will always be in order they may not all be output, so it's not just case of odd, even, odd, even (that would be too easy!)
I can retrieve the Previous Record's GroupNo value (via a function) in another text box and compare current GroupNoID with this in the Format Expressions and manage to change the colour, but it won't sustain this new colour for the subsequent same GroupNos, obviously as the values have changed.
So how can I....
Change the colour when the value changes. Keep this new colour until it the value changes (increases) again.
I have a Main form that has button that loads a new Pop Up form for entering new data that will display in the Main form. When all the data is entered I click on a button that Saves the data and exits the form and then runs Re-query on the main form returning to the record that was current before the requery.
I have the following code:
Private Sub cmdSaveTradeAndExit_Click() DoCmd.RunCommand acCmdSaveRecord 'Save the current record DoCmd.Close 'Close the current form Dim CrId As Integer CrId = Forms!frmTransactionMainActivePopUp.CurrentRecord Forms!frmTransactionMainActivePopUp.Requery DoCmd.GoToRecord , Forms!frmTransactionMainActivePopUp, acGoTo, CrId End Sub
But I am getting the following error:
Run-time error '2498':
An expression you entered is the wrong data type for one of the arguments
Im working on a make-table query that harvest records for calculation that span a "rolling" 13 week history... my problem is that the query will work if it doesn't have to retrieve work weeks that are prior to the new year. For example, right now is the tenth week of this year so i need to grab the previous 9 weeks of history plus 4 weeks of the prior year. then next week when the query is ran we will be in the 11th work week of the year therefor i will need to harvest the past 10 week plus 3 week of the preivious year. the query works if you don't have to span accross calendar years. here is the SQL of the query below the problem area is in underlined in bold type: SELECT PORVPHIS.VENDOR_ID, PORVPHIS.VEND_NAME, [Expr2] AS [Fiscal Year], DatePart("yyyy",[DATE_RECV]) AS Expr2, DatePart("ww",[DATE_RECV]) AS Expr1, PORVPHIS.QTY_RECVD, PORVPHIS.PO_UNT_PRC, [PO_UNT_PRC]*[qty_recvd] AS [Total Price], [Expr1] AS [Fiscal Week], IIf([fiscal week]=[LowWeek] And [Expr3]<>0,[total price],0) AS 1, IIf([fiscal Week]=[LowWeek]+1 And [Expr3]<>0,[total price],0) AS 2, IIf([fiscal Week]=[LowWeek]+2 And [Expr3]<>0,[total price],0) AS 3, IIf([fiscal Week]=[LowWeek]+3 And [Expr3]<>0,[total price],0) AS 4, IIf([fiscal Week]=[LowWeek]+4 And [Expr3]<>0,[total price],0) AS 5, IIf([fiscal Week]=[LowWeek]+5 And [Expr3]<>0,[total price],0) AS 6, IIf([fiscal Week]=[LowWeek]+6 And [Expr3]<>0,[total price],0) AS 7, IIf([fiscal Week]=[LowWeek]+7 And [Expr3]<>0,[total price],0) AS 8, IIf([fiscal Week]=[LowWeek]+8 And [Expr3]<>0,[total price],0) AS 9, IIf([fiscal Week]=[LowWeek]+9 And [Expr3]<>0,[total price],0) AS 10, IIf([fiscal Week]=[LowWeek]+10 And [Expr3]<>0,[total price],0) AS 11, IIf([fiscal Week]=[LowWeek]+11 And [Expr3]<>0,[total price],0) AS 12, IIf([fiscal Week]=[LowWeek]+12 And [Expr3]<>0,[total price],0) AS 13, DatePart("ww",Now())-13 AS LowWeek, IIf([fiscal Week]>=[LowWeek] And [fiscal year]<>DatePart("yyyy",Now()),0,[LowWeek]) AS Expr3, [LowWeek] AS week1, [LowWeek]+1 AS week2, [LowWeek]+2 AS week3, [LowWeek]+3 AS week4, [LowWeek]+4 AS week5, [LowWeek]+5 AS week6, [LowWeek]+6 AS week7, [LowWeek]+7 AS week8, [LowWeek]+8 AS week9, [LowWeek]+9 AS week10, [LowWeek]+10 AS week11, [LowWeek]+11 AS week12, [LowWeek]+12 AS week13, PORVPHIS.DATE_RECV, IIf([Expr4]="AS8819" Or [Expr4]="CO1870" Or [Expr4]="GV2510" Or [Expr4]="MC3105",[VEND_NAME],Null) AS ID, PORVPHIS.VENDOR_ID AS Expr4 INTO Tporv

I have a database and one of the functions is to track the purchase of fuel. Part of purchasing fuel is registering what the current odometer reads. My query gets the Vehicle ID, Date of Transaction and Odometer reading. I want to show a report that shows how many miles the vehicle is has traveled for a certain amount of time. If it's for 2013 then I'll put the criteria for 2014 in the date. This will give me a list of all vehicles and their odometer readings. I then sort the date by ascending.
In the report I group on vehicle ID and then I want to show all their transactions and add up how many miles were driven.
Vehicle 1
1/2/201 1/5/2013 1/15/2013 ETC... Total Miles Driven in 2014: XXXXXX
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.
Basically what I have is a form where operators can input certain information about a production process, in particular the kg input which has gone into the 'basket'. However this is divided by customer order number and sometimes more than one customers order is placed into the same basket. This means that the weight of the record is not representative of the weight in the basket, and it is the weight of the basket which determines efficiency in the process.
Each basket is designated a 'Disc Number' which is put in the basket so the parts contained can be identified after the process. What I am trying to do is right a code, whether in my table or form (or somehow creating a query) which compares the disc number of the previous record (or previous 2 or 3) and if they are the same the totals are combined. Each record the user places has a hidden ID which keeps them in order, and the records with the same disc number will always be entered after one another in that sequence.
How would I be able to code something to deal with this and where would I put it?The table in question which contains the records is called Thetatbl and then form it links to is Thetafrm. The weight of each record is contained in Orderkgtxt.
One of the common denominators between them is the URN which is auto-populated as it is an auto number field. My issue is that when I want to add a new record to the payments table using the forms (I can get to the payments form via the register form), I want to be able to identify the record that I am currently viewing within the register and auto populate the URN field with the same number. This is what I have done so far,
Option Compare Database Option Explicit Private Sub AttachPaymentDetails() Call PerformInsert("tblFinancialBudget", "frmFinancialBudget") End Sub
I was wondering if there is a code for Next and Previous record in a form but for a specific value.
Example: I have a customer that has a specific ID and that customer has a list of orders that all contain that ID. When I open a form for orders I would like to be able by using Next and Previous record buttons to be able that was to move only through records of that customer not the whole list of orders for every customer.
I have partially done it using PrevRecVal module I found on the web.
I created what I need to do in Access in Excel first, the problem doing this in Access (for me) is I need to refer to the results in the previous record, PrevRecVal worked but I need to finish if possible.
The main report holds client policy data of which InvestAmount is used to start the calculation of the sub report, the data entered to run the calculations on the subreport would be
I'm trying to make a form that shows what the last record was next to the empty space where you enter a new record.
This is so the user knows that what they are entering is roughly in line with what has come before.
So for example if I was recording temperature every May, I would like a form that has a field called temperature and next to that field I would like to see last year's temperature.
I am trying to write some vba code to auto fill a cell's value based on the value of the cell in the previous record (In a datasheet form) i.e. if the value in record one was '1' and the down-arrow key was pressed then the value '2' should be entered into the new ext record
I have written some pseudo-code to show what I am trying to accomplish:
if keydown = down-arrow and current cell contents isnumeric then Cval = current cell contents if current record = last record then create new record move down 1 record set cell value of new record to cval+1 else move down 1 record if cell value = null then set cell value of record to cval+1 end if end if
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've recently decided to move a database that had all its information on 1 table and divided it into multiple tables.
Attached is the relationship as well as the form.
The issue I have is that when I click the form, it only shows a blank record with none of previous records.
Data entry is already set to NO. I'm wondering if it's an issue with my relationships, tblStudioDescription is the parent table and the others are child tables so I linked them with the ID and set referential integrity.
I'm trying to make it a little further with my new call answering database at work.
Basically it consists of a main form that has a button leading to a call answering form for each business that we represent. it also has a text box that displays the number of the caller when the telephone picks up, the correct call answering screen is also popped by the telephone software and a macro whenever the phone is answered.
I've got code in place that automatically puts the date and time in the correct field and also copy the incoming telephone number from the main form into the caller number field on the call answering form.
I'd like to take this automation a little further now and get the form to autopopulate the caller details if that caller has called before (we get a lot of calls from the same people) so i'd like to make the form search the table it's linked to for the incoming phone number and to fill in the name, email, company etc... for the caller according to the previous record.
The code for the 2 forms i've currently got setup (the switchboard and one call answering screen) are as follows
Switchboard:-
Code: Option Compare Database Dim WithEvents MaxxCom As Metro_MaxxCom_CTI_COM_API.CTI Private Sub cmd_onnet_Click() DoCmd.OpenForm FormName:="On_Net_Communications" End Sub
I have a list box that my client goes through with vbKeyDown and vbKeyUp. When he finds the correct record he wants to do vbKeyReturn and capture the checktype code and description and have them placed in a check which is another form that is open. The following code does not work:
Private Sub List3_KeyDown(KeyCode as integer, Shift as Integer) If KeyCode = vbKeyReturn Then Forms!frmChecks![TRA{CODING = Me.CurrentRecord.Column(1) Forms!frmChecks![TRA:CODEDESC] = Me.CurrentRecord.column(2) DoCmd.Close adForm, "frmCheckType", acSaveNo KeyCode = 0 End If
I'm using: DoCmd.OutputTo acOutputForm, "Frm_EL_PL_Bulk_Send", acFormatPDF, outputFileName1...To save a form as a PDF. The issue is, it saves all the records in that set in continuous form, and I'm trying to get it to only save the record its on.
I have a form with a subform. In the form's On Current event I have the subform's visible property set to false. There is a button that when clicked sets the subform's visible property to true. I want the subform to go to the first control in a new record which is a combo box. the subform is a multiple items form. I have tried the GoToControl in the subforms OnCurrent event, but it is not working. I get an error saying the database cant find a third form.
While the validation runs a boolean keeps track of validated input and errored input.
After validation the validated input is dumped in the table.
Now what I want is de saving the errored record from "rsSQLIn" to be copied to a new .csv file.
The problem I have is that I cant seem to get the current record from the recordset "rsSQLIn". How do I reference this? I need the complete set of 24 fields being the same within "rsSQLIn"
I get this error when I delete more than one record consecutively.
Here is my delete code;
Private Sub Komut98_Click() Dim blnLast As Boolean 'MsgBox call must return the value in order to be checked. 'If user says no then cancelling is not required. It is only required ' that the deletion command is not invoked.
