Controling The Deletion Of Records
Mar 22, 2008
I have two tables which are connected with one to many relation, here are these tables:
tblCars
PK. intCarID
txtModelName
intManufacturerID
intModelPrice
tblManufacturer
PK. intManufacturerID
txtName
txtAdress
txtTelephone
Now, how do I achieve that when I delete a Car from the database, the Manufacturer is not deleted, because as you know one Manufacturer can create several model of cars, but when I delete Manufacturer all the cars from that Manufacturer are deleted? I know I need to enable cascade Delete but when I do that in each case when I delete a record from one database its relational record from the other table is deleted. How do I acomplish this?

I have a database with several forms, tables, queries etc. and it works fine. One of the users of the database accidentally deleted a record which was displayed by a query. I have selected AllowDelections = No in all object properties. Despite this, the record got deleted. Is there a way to prevent such deletions? Kindly help.

Been experimenting on some code to prevent deletion or changes to records that meet certain conditions.
The problem I am having is the code is contradicting each other preventing some of the records to be locked down.
Code:
Private Sub Form_Current()
'Code 1 - Prevent edits if 21 day period has lapsed
If TestDate2(Me.txtStartedHidden) > 0 Then
MsgBox "Editing NOT allowed - 21 day time period has been reached"
Me.txtBasic.Locked = True
[Code] ....
Rules are:
Edits allowed if invoice date not reached
Edits allowed if within 21 day but NOT if invoice date is reached
Edits prevented if invoiced date reached and if records still within 21 days
Edits prevented if invoiced date reached & records past 21 days

How can I control the size of my form. I would like some of my form with my program to open small, since they are small forms, and some large because they are the whole size of the forms. I hope I have explained this enough for someone to help.Thanks in advance.

Hello Gurus,
I need to perform a massive deletion within Access and I want to find out if there is a simple piece of SQL that can be written to complete this task.
Example:
I have a table called GAB - one of the columns is called email addresses
Currently all the email addresses look like this: m14.dpitts@****.com
I need them to look like this: dpitts@****.com, so all I need to do is remove the 'm14.'
Is there something within Access that will accomplish this?? Kinda like substr in Oracle?
Any help would be great!!! :)

I have a form with a sub-form and a sub-sub-form :p
If I try to delete the record being viewed in the sub-form using
With DoCmd
.DoMenuItem acFormBar, acEditMenu, 8, , acMenuVer70
.DoMenuItem acFormBar, acEditMenu, 6, , acMenuVer70
End With
Then I here a ding (like you do when you try to delete a record) but I see no record delete confirmation box come up, if I hit enter, it deletes. So its there, but I can't see it, it's not behind the form either.
Any ideas?
Cheers

can some one help.
i have two tables table1,table2 each with one same field Country.
In my RunSQl query, i want to delete all records in table1 and table2 simultaneously from one button with a certain country.
The problem is how can i do this from may be one RunSQL statement
i tried to use two deletion runSQl commands, but only one is executed. Actually the one that comes second.
If i put doevents in the middle of these statements, only the first is executed.
Here is my code:
Private Sub RemoveCtry_Click()
docmd.setwarnings false
Docmd.RunSQL "DELETE * FROM table1 WHERE (Country='" & USA & "')"
Doevents
Docmd.RunSQL "DELETE * FROM table2 WHERE (Country='" & USA & "')"
docmd.setwarnings true
End Sub
if I use One Statement:
Docmd.RunSQL "DELETE table1.Country,table2.Country FROM table1,table2 WHERE ((table1.Country='" & USA & "' ) AND (table2.Country=' " & USA & " '))"
I get an error that i have to specify the table to delete from!!!!

I have developed a database in Access which has user permissions implemented. These are set so that only Full Data Users have permission to delete information.
However, it has come to my attention that users can get around this by creating a query and then deleting records displayed in its results. I can't understand why this is possible, because the permissions should prevent this.
Can anyone help?
Thanks,
Gary

Hey all-
I'm trying to create a simple 1 field temp table to populate a combo box with the name of the current user and the word "Company." However, after the user closes the form (or as soon as the Temp table is no longer necessary) I would like to delete the table. I can create the table, the fields, add the data, and populate the combo box just fine, but I'm having problems deleting the table after I'm done. I keep getting the error:
Run-Time Error 3211: The database engine could not lock table 'Temp' because it is already in use by another person or process.
here's my code:
Code:Option Compare DatabaseDim dbRoofing As DAO.Database Private Sub Form_Close()dbRoofing.TableDefs.Delete "Temp" 'where i get caught when i close the formEnd Sub Private Sub Form_Open(Cancel As Integer)Set dbRoofing = CurrentDb Dim tblTemp As TableDefDim rcdTemp As DAO.Recordset Set tblTemp = dbRoofing.CreateTableDef("Temp")tblTemp.Fields.Append tblTemp.CreateField("Owner", dbText)dbRoofing.TableDefs.Append tblTemp Set rcdTemp = dbRoofing.OpenRecordset("Temp", dbOpenDynaset)With rcdTemp.AddNew!Owner = CurrentUser.Update.AddNew!Owner = "Company".Update.CloseEnd WithOwner.RowSource = "SELECT Temp.Owner FROM Temp"End Sub
thanks guys

Hi,
The user wants all of the records in the database to have continuous numbering. I have used AutoNumber in the past but if you delete a record, it produces gaps in the numbering.
I was wondering if there is a way to number the records so they are always numbered continuously (1,2,3,etc.) even if some record is deleted.
I have tried using the following:
Set db = CurrentDb()
Set recordlist = db.Openrecordset("SELECT Max(tblContactHistory.ItemID) AS MaxID FROM tblContactHistory")
ItemID = (recordlist!MaxID + 1)
recordlist.Close
Set recordlist = Nothing
but I still cannot get the records to have continuous numbering after a record is deleted.
Any helped would be appreciated.
Thanks!

I want to create a custom sequence when deleting a record but I'm having a problem.
What I want to do is prompt the user for the reason he/she is deleting the record and then archive this so it can be viewed in a log at a later time. This extra step is not as easy as I thought it would be.
What I did was put some coding into the On Delete event of the form. The code opens a form with a text box. The user can enter the reason for the delete in the text box and click OK or click cancel to abort the deletion.
My problem here is opening another form from the On Delete event. As soon as the form is open, the code just passes to the next step of the sequence and deletes the record.
There are 2 approaches that I've thought of but I'm not happy with either.
Approach 1:
In the On Delete event, set Cancel to True. That way the deletion is not handled by the delete sequence but rather by the new form that opens. The problem is that deleting a record from another form is not that simple. What I've tried is to execute a SQL statement that grabs the ID of the record from the open form and delete it. The problem is that although the record is deleted, all the fields on the form say #Deleted in them which is not that pretty. (Maybe there's some other way to do the deletion without this problem that I'm not aware of...?)
Approach 2:
Use an Inputbox. Unlike a custom form, the Inputbox delays execution of the code so the code can determine from the results (i.e. should it cancel the delete if the user clicked Cancel). The problem with Inputboxes is that they are not very flexible in the layout, they look pretty "packaged" (i.e. they look to me like the programmer didn't bother creating a means to enter a value). There's no way to place the buttons where you want or have it do better validation (e.g. I want the FORM to check that there's at least a few words describing why the user is deleting the invoice rather than have the form with the record get the input message passed back and then give an error and then pop open the Inputbox again)
I think that especially when you're creating an application with anything financial, you'll want to log a deleted invoice including the date, amount, possibly the client's name, invoice number, reason for deletion and the login name of the person doing the deletion. All of these are easy to record other than the reason.
Help would be much appreciated.

I created a form for project tracking. The form has a project name field in it that is a required field. The manager fills that out first, but may go back later to fill in additional data. I created a button to allow them to search for a project name, but they keep opening the form and typing in the project name they want to search for in the project name field of the first record that appears. This changes or deletes the project name for the record they typed in. Is there a way to prevent them from typing in that one field after a project name is initially entered?

I have a form and a subform. There are a number of buttons on the form, allowing me to add, update, delete, etc. records from the subform. The process is that I select a record on the subform, its details are displayed on the form, then clicking on <Delete>, for example, removes it.
Each of these processes work fine on their own and also if carried out one after the other, for the most part. The one problem I'm finding is when I delete a record.
Firstly, the subform appears to refresh and the record is no longer shown. However, if I then try to select another row from the subform, I get a message saying 'record is deleted'. I click on <OK> to remove this message and I can then select the same row or another row without any problems.
Secondly, if I now try to add a new record (the code behind the button is just 'DoCmd.GoToRecord , , acNewRec'), I get a message saying that I can't go to the selected record.
If I close and reopen the form between each activity, all works fine, suggesting that something isn't refreshing properly. I've tried putting 'Me.refresh' and 'Me.requery' immediately after running the deletion, but to no effect.
Any suggestions?

I'm using this stardard piece of code on a button that deletes a record from a simple continuous contact form.
Code:
If MsgBox("Do You Want To Delete This Record?", vbQuestion + vbYesNo + vbDefaultButton2, "Delete?") = vbYes Then
DoCmd.RunCommand acCmdSelectRecord
DoCmd.RunCommand acCmdDeleteRecord

If the form is called "CONTACTS" with a field called "Contact_Name", what code do I use to have the relevant Contact_Name appear in the MsgBox to be sure that I'm deleting the correct record ...... something like this .....

We need to reset the autonumber after the last record is deleted.
For example:
2006
2007
2008
if 2008 gets deleted, we want the autonumber to reset back to 2008 rather than move to 2009.
Is this possible? This is the code we are using but cannot get the string to recognize the variable. If the variable is replaced with a number, it works, but it defeats the purpose of adding the plus 1 to the last autonumber.
Code:
Private Sub Command0_Click()
Dim RLMax As Integer
Dim Statement As String
RLMax = DMax("[id]", "Table1")
RLMax = RLMax + 1
strSQL = "Alter table table1 Alter Column Id Autoincrement(RLMax,1)"
DoCmd.RunSQL strSQL
End Sub
I realize we don't want to depend on the autonumber for anything other than a row identifier, but the table is setup that it is important for the rows to be sequential if the last record is deleted. Only if the last record is deleted.

In a simple Access 2003 database that has two table. A contacts table and a Report table.
I would like to be able to prevent the deletion of any contact that is still being used in the Reports table. The problem is that they are in a backend of a linked database. So the enforce referential integrity doesn't work. Plus I don't think I would like it anyway as it seems kind of dangerous to the reports table.
Is this possible to do what I need through the use of form coding?

I have 2 tables.
1- customers table with 2 fields : customername,customerno
2-conversationstable with 4 fields: date,customername,customerno,details
The conversations table is for keeping memo of telephone conversations with the customers.
I built a simple form deriving from the conversations table. And added to it a combobox with 2 columns from customers table to select the customername an customerno for the form.
While deleting the record in the conversations table,through the form, I saw that the customername and customerno in the customers table of that particular customer record are deleted also. I made no links between both tables.
I wonder why that happened.

What I would like to do it take all 'RoleTitle' from RolesList, all 'CourseID' from courselist and show them as a pivot table/matrix with a checkbox that creates or deletes entries from the RoleRequirements table. So, if it exists in the RoleRequirements table then it should appear a checked, unchecking it would delete it from the table.
I am using access 2010 with a SQL server 2005 backend.

My 2nd post, and I am very new to DB and Access. I have a problem that I want to get help on. I want to set up a main form that is used to enter and delete all data for my table. I wish to add either a button or to make it automatically happen when a record is deleted, that it is first copied to a separate table with the same fields, except it also has a closed date that would be the date that the record was copied over. I know zilch about VB, VBA or any other language other than AutoIt, so assume I am what I am, an ignorant beginner.
I did look into the event somethihng like upondeletion or something... while trying to find help on this in the access and VBA parts of Office, but I do not know how to utilize the event with Basic or SQL, which I know none of either.
Any help or examples are very much appreciated.
**EDIT**
I do not require all fields to be recorded to the secondary DB (History), so if someone can just give me an example of how I would move two fields to a separate DB, I can hopefully learn enough from it to do more.
Thanks a Bunch!
EXAMPLE**
Current Loans (Table 1):
CustomerID
Name
Address
City
State
Phone
Customer History (Table 2):
CustomerID
Name
Phone
That gives an example to help understand what I need. I want to store the CustomerID, Name and Phone values of the record being deleted, to the History Table, which I am using as a closed account table for later look up.

In my Membership Database (Access 2010), I have a Table entitled [Foreigners] in which are stored the names of prospective members of the organisation and the name and ID of the Interest Group they are proposing to join.
When a formal Application to join is received their personal details are recorded using an Entry Form related to the main [Mail List] Table.
The current procedure then is to manually delete the entry from the [Foreigner] Table and finally to record their Interest Group data using another Entry Form entitled [GroupMembers]. This relies on an operator remembering to do the necessary.
It occurs to me that this process could be automated. I wondered whether it could be entirely automated or would be best effected with a button on the main Entry Form, such that on completion of data entry of personal details the button would be activated to do the necessary deletion and addition.
The [Foreigner] Table is an entirely stand-alone table, having no relationship with the other concerned tables. The only common factor will be the Member Name, which in the main table is a concatenation of First Name & Surname..

In an Access 2010 form is it possible to export select records and fields in those records to a specific location?
Code:

With objDialog
.AllowMultiSelect = False
.Title = "Please select a File"
.InitialFilename = "C:"
.Show
If .SelectedItems.Count = 0 Then
MsgBox ("Action Cancelled")
Else
[code]....
The user can select the directory using the code above, but can specific fields in records be exported to a excel workbook in that selected directory?For example, if the are 5 records in the database can the fields LastName,FirstName,BirthDate in records 1,2,3 be exported to Setup.xlsx in that selected directory?
