I dont want to allow for the same product to be put on one order twice. Therefore, (orderNum,productNum) must be unique, but productNum is not a part of the primary key so it can be repeated in every row for all the database cares. :P
I have an Access 2002 database with a relationship between 2 tables I want to delete using VB code. I setup the relationship from within Access. Is there a way to find out the name of the relationship, if there is such a thing. The tables are: TableA.Id linking to TableB.BankAcctId with both cascade functions. What would the VB code look like? Something like ALTER TableB DROP CONSTRAINT ... Thanks
format: tape; dvd region: 0;1;2;3;4;5;6;7;8;pal;ntsc rarity: 1;2;3;4;5
I have a check that makes sure (format, rarity, region) is unique.
It works fine until i set region to either "pal" or "ntsc", then I get the following error.
"Error 'Error evaluating CHECK constraint. ' in the validation rule."
I set up the constraint by going to table design view -> indexes -> created new index with each of the three fields listed one after another -> set to primary=no, unique=yes, ignore nulls=no.
Can anyone help me work out why im getting this problem?
I have developed a small hotel booking system which inserts records into a reservations table. The table looks like this: [ReservationNr][StartDate][EndDate][RoomNr]
I am now trying to add a constraint which prevents a room from beeing booked twice on the same day, hence the time period defined by StartDate and EndDate in a record must not overlap with another record. Is Access capable of adding such a constraint? It was easy to add a constraint that prevents a booking where the StartDate is before the EndDate, but this one needs to reference already existing records. Any help would be much appreciated.
Hi everybody .I created a bounded form that allows user to enter the following fields information to the sql server db that is linked to access .The fields are: Projectno, taskcode, taskdiscription and total hours worked.
I want for example when a user tries to enter total hours work for a user (Hours in hours worked table) and if he did not already enter wages of the employee for that particular project (amount in hourly wages table) that user get a massage prompt and ask user to enter amount in to hourly wages table first. Possibly opening that form.
I be happy if some one help me add this feature to my form. Thanks
The first table is created just fine. And if I leave the constraint clause out, the second table is created also. If I try to run it as an SQL query right in Access, after the error is delivered, it highlights the word DELETE, and if I reverse the update and delete portions, it highlights the word UPDATE.
I have looked up the clause in Access help and even using their example, i get the same error.
I am developing a simple database for students to register courses using Microsoft Access 2010. I have 4 tables: Student, Register, Course, and Section (1 Course can have many Sections).
Then, there is a criteria that a student can only take up to 6 courses. Hence, may I know that where and how can I include this constraint? I believe that it should be in the Macro (Before Change) of the table Register...
My relationship is: Student -> Register <- Section <- Course
I have the following in the after update event in a Combo bound to a tbl on a Main form; Sub Combo8_AfterUpdate() ' Find the record that matches the control. Me.RecordsetClone.FindFirst "[Vendor] = '" & Me![Combo8] & "'" Me.Bookmark = Me.RecordsetClone.Bookmark End Sub
The Combo gets its data from a table and I use the Not In List to add data which is not in the Tbl and of course Limit To List is set to Yes. It works ok with one exception, when data is entered, but not saved, then deleted And the form closed. In this set of circumstances I get an error in the code above. Granted that normally a user will not delete data from the combo then exit the form but it does happen occasionally. I have tried adding On error goto.... but with no luck. Any suggestions?
I've a form in which one of the fields the user enters is supposed to be a unique id. The unique id is an alphanumeric text box.
However, it's possible that another user enters an id that has already been previously used.
I'm thinking that I need to run a Find Duplicates Query with the text box entry and a table that holds all the previously entered ids prior to the form being saved so that I can inform the user of the possible duplication.
My question is are there any ideas on how I can do this or code it?
So on the offchance that two clients are trying to autogenerate a key at exactly the same time, I'm trying to trap the 3022 error raised when a duplicate key is entered so that I can repeat the operation with a goto.
I'm raising the error with requery like this:
DoCmd.Save acForm, Me.Name 'next line triggers 3022 DoCmd.Requery
After I realised that the normal handler wouldn't trap it I got the database from this thread:
I have a VBA code that runs an append query to update a table. Due to relationship integrity a validation error shows (a type does not exist in the connected table): What I want to do is trap the error and write something that the user can understand. Help !

I have a "homemade" switchboard that I am using and the first page allows the choice of administrator or user. I have used access user level security to deny all but administrators access to the administrator "path" in my switchboard.
When a user clicks on it, they get the runtime error 2603 saying that they don't have access. I am trying to modify the on error event so that the error won't show up and a custom message box I create will show up instead, however I cannot seem to get my on error code to do anything. I always get the standard access runtime error return box. Does anyone have any ideas??
I have an "Error trapping" problem. I am relatively new to VBA and wondered if someone would be so kind and point out the error in my code.
I have a form "frmSelectInvoices" that opens another form, "frmInvoice".
I use the Select Invoices form to select completed jobs that are not invoiced, based on a query.
The user would then select a job that he/she wants to invoice, and "frmInvoice" opens in front of "frmSelectInvoice".
"frmInvoice" is based on "tblInvoices" and a couple of the required fields, (customer, JobID, etc) are filled-in automatically using the information from a couple of fields from "frmSelectInvoice"
"frmInvoice" also has an InvoiceNumber field which tblInvoices needs as it is set as a required field with no duplicates, (this is NOT the primary key).
I am trying to notify the user that the InvoiceNumber has already been used, and to reset the record, so they can enter a new Invoice Number.
The code I have so far is as follows; Code:Private Sub Notes_Exit(Cancel As Integer)On Error GoTo Err_SameNumber Dim iResponse As Integer iResponse = MsgBox("Do you wish to Print an Invoice", vbYesNo, "SELECT AN OPTION") If iResponse = vbYes Then DoCmd.RunCommand acCmdSaveRecord Forms!frmSelectInvoice!Invoiced.Value = True Forms!frmSelectInvoice.Requery DoCmd.Save acForm, "frmInvoice" DoCmd.OpenReport "rptInvoice", acNormal, "", "[pkInvoiceID]=[Forms]![frmInvoice]![pkInvoiceID]" Me.btnClose.SetFocus Exit Sub End If If iResponse = vbNo Then MsgBox "You can Print it out later from the Invoices Main Menu", , "You Selected NO" End If DoCmd.RunCommand acCmdSaveRecord Forms!frmSelectInvoice!Invoiced.Value = True Forms!frmSelectInvoice.Requery Me.btnClose.SetFocusExit_SameNumber:DoCmd.RunCommand acCmdUndo DoCmd.GoToRecord , , acNewRec Me.fkBookingID.Value = Forms!frmSelectInvoice!pkBookingID.Value Me.fkCustomerID.Value = Forms!frmSelectInvoice!fkCustomerID.ValueMe.InvoiceNumber.SetFocusExit SubErr_SameNumber: MsgBox "Invoice Number has already been used", vbInformation, "Please use a New Invoice Number" Resume Exit_SameNumberEnd Sub When I test the form with a number I know already exists, or even a number that has not been used before, the error message comes up and it then sets the focus to InvoiceNumber, but when I try and close the form it still keeps coming up and the only way I can get rid of it is to close the application using Windows Task Manager. Any help on this would be appreciated. Thanx
Hi guys, I was looking for a way to trap err.number 3314 (when required field is null) before Jet generates its warning. I came across an old post from Rich (below), but I couldn't make it work as yet. In the calling form, under the Form_Error event I wrote the following:
Dim f As Form Set f = Me Call fnValidateForm(f)
Could anyone please tell me where my error lays here? I have several forms which have several text and/or combo boxes bound to required fields and I would want to have a generic code, like the one here to trap errors before Jet shows it's Error Message.
Thanks in advance Regards Jaime Premy - Belém-Brasil

I like having the action query warning appear with what I am doing - "You are about to update xxx rows". The problem that I am having is that when my RunSQL statement in the code executes and selects no to the warning, I get the error -
Run-time Error '2501' The RunSQL action was canceled.
How can I trap the no selection so that this vba error does not appear?
Ok, I have a delete query that I use to delete records form a table. I have created a form that I run that query from. It has Delete button that runs the query. After I get the message that says "You are about to delete 56 records" and I click No, I get a "run-time error '3059'. Operation Cancel by user"
I did some searching on the forum and thought I could trap this error. But I still continue to get the error at
"DoCmd.OpenQuery stDocName, acNormal, acEdit"
What am I doing wrong and how can I prevent this error from appearing when I click NO or cancel the operation.
Private Sub cmdDelete_Click() On Error GoTo Err_cmdDelete_Click
cmdDelete_Error: Select Case Err.Number Case 3059 MsgBox "You have canceled the delete operation.", vbOKOnly, "Delete Canceled" Exit Sub Case Else MsgBox "Error number: " & Err.Number & " has occurred. " & Err.Description, vbOKOnly, "Error" End Select
I've made my own record navigation buttons on a form. they work fine, except when i get to the first record. if i click 'previous' then the 2105 error pops up "you can't go to specified record". the buttons were created through the wizard, and have error trapping in them. for some reason, it never actually goes to the error handler. the error message comes up, i press debug, and the 'DoCmd.GoToRecord , , acPrevious' is highlighted.
any ideas why the error trapping isn't working? here's the code:
Private Sub cmdPrevJob_Click() Dim x As Variant On Error GoTo Err_cmdPrevJob_Click DoCmd.GoToRecord , , acPrevious Exit_cmdPrevJob_Click: Exit Sub Err_cmdPrevJob_Click: If Err.Number = 2105 Then stop MsgBox Err.Description Resume Exit_cmdPrevJob_Click End Sub
I've got my form working, and all of the record updating is working fine, so now I am working on error trapping. I need to check if any of the two textboxes are empty, or nothing has been selected from the combobox. I am using the BeforeUpdate method. I am not getting any syntax errors. I am using an INSERT INTO SQL statement. Thanks.

We are currently developing a simple Point Of Sale Form which consists of 2 text boxes and a list box.We need to trap numeric input from either the keyboard or a barcode scanner at form level,then setfocus on a textbox and enter the input into the textbox.So far have used the keydown event on the form to trap numeric input and setfocus using the following code.
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer) If KeyCode >= 48 And KeyCode <= 57 And KeyCode >= 96 And KeyCode <= 105 Then Me.Input.SetFocus End If End Sub
This does not however enter the keyboard or scanner input into the textbox.Is there a method to trap the input,set the focus and enter the input into the textbox once it has recieved the focus.
I am using following routine to lift data from Excel files into Access tables. Whole thing works, well, most of the time. The only issue I have is the spreadsheets are received from warehouses and even though they have been given strict instruction to stick to the template, I have had to adjust the spreadsheets. Amongst errors I get are:
Field 'F16' does not exist in table 'SA1'. (In this case I simply delete the last most empty column to fix this).
Or there are column name spellings and in such cases, I get no error and the simply code hangs.
Is there any routine that I could incorporate in the code that clearly states what issues are being experienced. This way I can pass the db to the user to run it themselves.
'Dim dbs As Database, tdf As TableDef Set dbs = CurrentDb On Error GoTo Macro1_Err DoCmd.SetWarnings False ' RunSQL executes a SQL string
What's the best way to trap the error I get when I don't input the time correctly in a date/time control?? I have a the following as an input mask: 99:00 >LL;0;_...02:30 PM
I am writing a small database using MS Access 2007. I have in it a function for running queries and printing reports. Printing works just fine if any one of the multiple query criteria is give.
I also want to trap errors and present a message if the user clicks the "Print" button without a query criteria. At the moment I only get a run-time syntax error message which has a "debug" button for accessing the entire code. I want a message that will say "There was no search criteria".
This is the code for printing:
Code: Private Sub cmdPrint_Click() Dim varWhere As Variant varWhere = BuildFilter ' Update the record source Me.RecordSource = "SELECT * FROM q_Vehicles " & varWhere
