I have a specific question on the datediff function.
My example is =DateDiff("d",[Policy Issue Date],Date()) where [Policy Issue Date] is the inception date of an Insurance Policy.
I need to determine how many days the policy has been inforce. The formula works great in a query and I can see the number of days in that field when the query is run.
However, my dilemma is I want the same function to run off of a text box using its control source property and have the number of days calculate and be visible for each record on the form. This part is not working and the field is returning the #Error? message.
Basically my database is for a library based on borrowing/returning books ect
Everything works except this one thing, in one of my forms I can ask the user to input a book number of the book they want to check if it has been returned or not, if it hasnt been returned within 30 days then it will come up with overdue.
The statement im trying to use i cant get it to work.
=IIf([DateDiff("d",[Borrow Date],Now()>30)
I want it to display overdue if the book isn't returned in 30 days of the borrow date.
I am struggling with the DateDiff fuction in a calculated field. After some study, I have used several variations of:
=(DateDiff("d",[DUED],Date())/7)
to calculate the time (in weeks) until a due date starting from today's date.
It continually turns up a specific date in the late 18 and early 1900's. It does not give me the number in weeks which was what I was hoping for.
Earlier I used a very simple: =DateDiff("m",[Birthdate],Date()) to calculate the age from a date of birth perfectly with no problems.
I do not understand why the formula is not working. Does it have to do with format or the fact that I am working with a future date and how can I rectify this problem?
I recently created a database to be used to store incoming invoices. We have 4 suppliers which supply the same material and wanted each supplier to have its own database.
I began by making a database which included all the key tables, forms, queries and functions I would need to then save 4 copies, one for each supplier. This just meant I would not have to repeat the process for each individual supplier.
The problem is all my data is external and upon importing it into the database it has made the search function (combo box) not return results.
I believe this is because: 1) The form was created before the records existed 2) The records were imported from an external source and not created using the form.
However, the way I have designed the form is so I can see all relevant information linked with a specific invoice. This aids in gathering information quickly about an invoice but also so I can input credit note and invoice query information linked to a specific invoice on the same page.
Is there anyway to remedy this?
Or use a similar search function that returns records in my form "Main View"
The last thing I want to do is have to create the form again, although I don't think this will work either as reason 2) states.
I would like to ask if I would like to count the number of days between two date, but EXCLUDE Fridays, Saturdays, Sundays since the workers ONLY work Monday thru Thursday. I am using the function DateDiff as follow:
DateDiff("d",[Date1],[Date2]) with Date 2 is later than Date 1.
However, the results count calendar days. HOW do I exclude Fridays thru Sundays fall within Date 1 AND Date 2?
I have an IIF function specified on a continuous sub-form as below - basically it checks to see if the value of two text boxes is equal, and if they are it displays 'And', if not it displays the value of the column EntitlementName. I'm trying to work around grouping not working in continuous forms.
When I view the form directly it works no problems but when I view the form as a sub-form instead of showing the correct output it shows #Name? Both the text boxes I refer to have the correct values in them.
I've created a database where a query who'se result is loaded on a form uses following function --
DateDiff('d',Date(),[Target Date])-(DateDiff('ww',Date(),[Target Date])*2)-(Select Count(*) from [tblHolidays] where [HolidayDate] between Date() and [Target Date])
I've notice that 2 ppl get an error message when they try to open database, with thatt function coming on an error message Does this mean they have older access version ? How can I tell ? Any advise on what to do ?
I am finishing up a database that logs basic activities/tasks for my coworkers. As they go in to the database and log an activity in it stays open until they end their day or they start a new task. All this works fine, but the problem comes when I try to determine the total time spent (in hours) on each activity/task. I have written similar queries before and they worked just fine, but for some reason I am having trouble getting this one to work. Here is the expression I'm using...
Time Diff (in hrs): DateDiff("h",[Sample_TM_Table_1]![Time_In],[Sample_TM_Table_1]![Time_Out])
Unfortunately, say Time_In = 8:32:38 am and Time_Out = 8:33:03 am The expression says that is equal to 946632.
For another Time_In = 8:33:00 am and Time_Out = 3:18:19 PM. The expression says this equals 946639.
I have tried changing the format of the date/time in both Time_In and Time_Out fields to ensure they were the same and cross checked the expression but still get the same answers each time. Even when I try to use "n" for the interval or "s" it is still highly incorrect. The only thing that makes me think I still have a formatting issue is that the Time_In shows a long date on the results table while Time_Out shows it in a general date format. However, when I go into both the table and the queries to check the formatting they both show general date. Any ideas? I'm all out! Thanks in advance.
I am trying to calculate the difference in dates between two fields. How do I find the difference in days between field one which contains the date 04/12/2011 and field two which contains the date 04/12/2013? I have tried to use the datediff function, but it keeps telling me it doesn't recognize the field name, even though the spellings correct.
I have a form "NewMetalF" that has three combo boxes. The first one is used to choose "Precious Metal" or "Base Metal". The second one shows all the metals based on the first combo box. When I open the form in form view alone the combo boxes work flawlessly. I run the form "NewMetalF" within another form "NewExternalPartF" by clicking a button "AddMetal". When the button is clicked "NewMetalF" opens. The first combo box is selected, and when the second combo box is clicked the error "Enter Paramater Value" "Forms!NewMetalF!cboPreciousOrBase".
I have a large query that basically collects all informations for a given record from various tables. The query is then used as a controlsource for a report. It works fine. However, one of the tables referenced is a one-on-one relationship to the master table and there some records that do not have any corresponding records in that child table. I've entered in Nz() function for all fields from the child function to prevent the records without child records removed from the query's recordset, but it doesn't work. That is, query returns all records that has a child record, but not those without.I've already checked the Join properties to ensure that all parent records are displayed and only child records where there is a parent records.What should I do?
I developed a database in 2005 and used the 'Left' function in many of the queries to obtain the the correct text for output to reports. The database worked extremely well for a year and a half.
I have not accessed it for the past year. Recently I opened the database for use with a new project and I keep receiving the error message:
! Undefined function 'Left' in expression.
I haven't changed any of the expressions and do not understand why this funtion no longer works.
I am using the “count function” on an MS Access 2003 Form field. The count function seems to be working fine except it is not placing the result into the table field.
Does anybody know what I am doing wrong?
Can someone show me the proper format for using the count function used on a form field, where the result is to be placed in a table field?
Please Help!!!

I have an Access 2010 database with two tables and two forms. The tables are Organizations and People. Similarly, the forms are Organizations Entry Form and PeopleEntryForm. The People are linked to the Organizations table. Several people can be linked to the same organization.On my Organizations EntryForm, I created a command button to duplicate a record using the wizard. It works fine.
I did exactly the same thing on the PeopleEntryForm, but instead of copying the record, it creates a new blank record. I don't get any error messages. Is my problem due to the fact that the People table is linked to the Organizations table?
I have a bound form to an invoices table. The form details all invoices raised, all payments made and an outstanding balance. The outstanding balance control is just a basic text box.
On form load, I go to the payment table and select all payments into a recordset, I then add up all payments and use the following calculation:-
Balance = InvTotal - paytotal
The Invtotal is the control on the form that has it's control source set as sum(invoicetotal)
The calculation used to work and the correct balance was displayed, indeed, for one particular client, the calculation works, but for all others, the summed value is blank and so the balance is effectively set to the paytotal value.
I know this is to do with the timing as the form loads and it's records/data are made available, as I have an update button that does exactly the same things as the form load and when pressed, all numbers work.....primarily because the summed invoicetotal value is now available in the form control.
I can see what is happening, but not sure why...I thought that form load gave you all records and would have populated the summed control before triggering the load event....obviously not.....
I have a code module in my interface with 3 functions that run via separate forms with user inputs. Each function is similar in design, exporting data from a generated query to excel for input into external software.
The database is split into an interface FE (Access 2007) with linked tables BE (Access 2000). I have successfully tested each of the 3 functions in my code module with a set of tables containing fake test data. However, I have discovered that if I link to a different copy of the .mdb tables, 2 of the export functions no longer work and the third one still works fine.
What is causing the problem but the part that is not working correctly is the loop.
Here is my code module:
Option Compare Database Option Explicit Public Function CreateQCStaticChartsforReports() As Boolean 'Define variables for Static Chart creation Dim qdf As DAO.QueryDef Dim strSQLStatic As String
I'm trying to create my own database dealing with hiring bikes on a daily basis.
I have created a form for the basic input, including StartDate, StartTime, EndDate and EndTime, followed by TotalDays. I added the time field so that if a client brings a bike back an hour or two after the pickup time on a later date (sounds complicated - e.g he takes it on Monday at 12pm until Thursday 14pm) then he would be charged for an extra day. It is similar to the car rental system used worldwide.
The TotalDays is currently using a simple expression =EndDate-StartDate.
Is there any way to make the form incorporate the time difference so that if EndTime-StartTime>1 then it would add an extra day to the "=EndDate-StartDate" calculation.
I've just started using 2010 and, unlike previous versions, the expressions that I've put on controls in a form are not working. Is there a setting that has to change that's new to 2010?
