Get Previous Field Value In A Query Without A Form
Aug 20, 2005
I have been looking at some of the solutions to the running sum problem.
The queries I use cannot use the primary key as there are gaps as some filtering has been done with an unmatched query to give me my sample dataset.
From this dataset I have a list of courses and the number of learning hours per each course. This is the field I would like to perform the running sum on.
Its a parameter query and the intention is to email the query the the various schools so no form was necessary.
The solution on microsofts web site wants me to use a form and I dont understand how it works anyway.
Is there a code solution that can use a recordset that doesnt rely on forms?
At present I am reliant on the date which does work but not where a student does two courses on the same day. The forums advice was to use the autonumber but there are gaps in that so that doesnt work. can I generate an autonumber on the fly as an expression and use that in the sub query method?
Fields:
[Date][Person Id][Course Code]
[Course Name][GLH][Running Total][UpliftCode]
[50%][Rule Broken]
what I have so far:
SELECT Pro.Date, Pro.[Person Id], Pro.[Course Code], Pro.[Course Name], Pro.GLH, (Select Sum(Pro1.[GLH]) FROM [QryAllEnrolmentsWithoutMatchingQryWithdrawls] Pro1 WHERE Pro1.[Date]<=Pro.[Date]) AS [Running Total], Pro.UpliftCode, [Running Total]/2 AS [50%], IIf([UpliftCode]="99","No",IIf([GLH]>[50%],"N","Y")) AS [Rule Broken]
FROM QryAllEnrolmentsWithoutMatchingQryWithdrawls AS Pro
ORDER BY Pro.Date;
kind regards in advance

I have my Assets form and the primary key is the ChargerID, in this form I have an "Add New Job For This Asset" button, which opens up the Jobs form at a new record.
How do I make it so that the ChargerID field is automatically filled with whatever the previous record was instead of being blank.
For example if I have Charger12345 open in the Asset form, I'd like to click the Add New Job button and it automatically have Charger12345 in the ChargerID field of the Jobs form.

I have a table called welding, I want to create a user friendly form for input. The database ultimately wants to go on share point so I am building it in the web database option.
One of the fields is called location, if the location is 'Field' I want 10 more fields to appear for data entry such as weld reason, rail temperature etc . If the location is 'Depot' I want these fields to be hidden as they aren't relevant.how would I do this?

I'm working with a form (MainF) ... which has a subform (MainSubF). The subform has buttons that link you to other forms. When you click on one of those buttons, I have a control number that links the two forms by putting a CTR field into the linked form with a ctr defaul that = forms!mainf!ctr.
My problem is that I'd like to use this subform on other forms. However, if I put the subform onto another form such as "MainTwo", none of the buttons on the subform will work because the path is now wrong. Is there a generic way to connect the buttons to whatever form the subform is attached to??

I've got one form that a user will start on, titled "Query Form" - Only one text box is here and it is titled "text0"
Upon hitting enter here, a new form is opened up titled "Time_IN_Form".
What I would like to do is have the value from text0 on the Query Form to automatically populate Emp_ID on Time_IN_Form so the user doesn't have to enter their employee number twice (only once via the first form).
What is the best way to do this? I have tried playing with global variables but didnt have any luck with that.

I have a big table, EquipmentDetails and separately I have job plans.Job plans can have many pieces of equipment. I store the relationship in EquipmentDetails_JobPlanDetails, but am feeling frustrated as I can't seem to get Access to build the SQL query from this in the way I want.
I am generating a List Box in a form which is populated from a query.The query calls on a table which lists ItemID from EquipmentDetails and JobID and in the current form (where the list box is) I want to pick up and display the ItemIDs associated with that JobID. The current JobID reaches my form correctly (I've proven this by displaying it in a text box) from the previous form.
The problem I have is that I can't seem to get the SQL query to only get ItemIDs that are linked to the current JobID. No matter what I try, it either gets all of the ones in that table, or I can't compose one.What kind of SQL do I need to only grab the ones relating to the current JobID please?I've tried building it in the design view but it says that it can't do it because the outer joins are ambiguous.

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've just returned to work after kids and started managing a large Access database related to health, back-tracking over many years.
Currently in filling a form we physically enter:
Apples 2.2
red apple 2.4
red apple cut 2.45
Oranges 5.6
Cucumbers 8.5
Is it possible to get field 2 to automatically fill with a number code due to the text typed in field 1?
FWIW, I'm confident at more basic Access e.g making follow on default value = Dlast("field""table") type stuff but the more complex stuff I haven't touched since Uni over a decade ago and you will need to be gentle while I blow away the cobwebs

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 ....

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".
How can I do this?
Thanks,
Dave

Hi,
I have a user who would like the value from the last entry into the form's title field text box to show as the default value when he clicks on enter new issue button to bring up a new record. I do not know if this is possible but I thought I would check for him.

Okay, here's the query as simplified as possible:
Month - Days - PreviousMonth
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
Thanks in advance for the help.

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.

I am trying to autofill a field based on the value of a previous field on a filtered form. I think the fact the records are filtered is throwing me off. Any help for me?

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.

hi
i have a form (A) with some unbound combo boxes which generate a subform (continuous) recordsource and the records output
after i filter the subform, i click on a subform record and open another form (B), and close form (A)
i do a bit of editing on form (B), then i click a button to go back to form (A).
is it possible to open the form (A), with the unbound combo boxes values at the same value as when form (A) was last closed, and as such the subform records output as per when the parent form (a) closed
if this is possible i can then have a button on form (B), to go to the next or previous record on the form (A) subform
apologies if this sounds confusing, many thanks in advance

Hi There,
I was wondering, in a form (to add records in the Table) with a date field, can I limit that field to only previous dates. This will reduce errors in the table, no future dates anymore.
Thanks in advance,

I would like the text from the previous field Invoice_Contact copied into the field Invoice_Contact of each new record created. I think I can use CTRL ' - but would like it done automatically if possible.
Field location:
Form = PatientUpdate - Subform = F_Invoice - Field = Invoice_Contact
The form and subform are linked through: Pat_ID
The subform is based on the table called Invoice with Invoice_ID as the primary key.I tried several variations of this DLookup from examples I found on the web but the field comes out with "error" in it and its flashing!

I have a company that has a field for MailingAddress and PhysicalAddresses for shipping. When I enter the mailing address information I'd like the shipping to automatically populate with the information; however, I want to be able to change the physical address, if it differs. Is there a way I can do this without using a combo or list box? I tried changing the control source, which works, but I can't go in and make a change on the physical address without it re-populating the mailing address.

I have a query that displays the difference between the number of scanned and processed invoices for each date (invoices scanned minus processed). Now I would like to make a query that for each date based on this shows the total backlog accumulated.
Example table:
The first column contains the date, and the second number of invoices scanned minus invoices processed.
2014-01-02 53
2014-01-03 -15
2014-01-04 24
Would it be possible somehow to make a query that for each lines shows the complete sum of all previous lines?
Based on the above data the result should be:
2014-01-02 53
2014-01-03 38
2014-01-04 62
Or would I have to write some VBA code to create some kind of temp table?

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.

It is a continuous subform (Names: Form = ClientUpdate / Subform = ClientUpdateSub.
All of the data implicated here is direct and in the subform's query table including the button we want to program.
(This is my example but it wont stay in columns in this "post box" )
IDNo App _ID App_Freq App_Date GetDates Action_Date
22 18 56 21-Jun-13 BUTTON 14-Jun-13
21 19 56 16-Aug-13 BUTTON 9-Aug-13
*
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 a form whereby a user for my database can be created. The fields required are listed below:
Payroll ID
Forename
Surname
Location
Manager
The last two fields are related to two other tables; tblLocation and tblManager, which are related to one another.Each location (there are three) can have more than one manager, however, a manager can be associated with only one location.I would like whomever is creating the user to only be able to select a Manager that works at a particular location, currently, I can select LocationID 1 and ManagerID 3, but ManagerID 3 works at LocationID 2.
How can I base the 'Manager' field in my form on the previous field's selection, e.g. 'Location'.Also would need to restrict the order in which the form's fields are enter, i.e., 'Location' before 'Manager'.
