Deleting A Record From Access Table By Id Using Dao Recordset?
Apr 3, 2012
I am trying to delete a record from a table by using dao recordset. Currently I am working with the code listed below. Unfortunately i've realised that this code only deletes the first record in my table, whereas I am looking to delete a record form the table with an ID that I would have put in textbox1
Private Sub btnDelete_Click(sender As System.Object, e As System.EventArgs) Handles btnDelete.Click
Dim AccessEngine As New DBEngine
Dim db As Database = AccessEngine.OpenDatabase(DatabasePath)
Dim dbs As Microsoft.Office.Interop.Access.Dao.Recordset = db.OpenRecordset("myTable", RecordsetTypeEnum.dbOpenDynaset)
dbs.Delete()
End Sub
I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.
I would like to have a pop up messagebox that asks users for confirmation before deleting a record in datagridview and if the record is a foreign key to another table, another messagebox will appear and warns users saying" before you can delete this record, make sure you remove all the related records" I have tried but I don't know how to complete it.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.StaffTableAdapter.Fill(Me.StaffDBDataSet.Staff) BindingNavigator1.DeleteItem = Nothing End Sub
I have this problem : Dynamic SQL generation for the DeleteCommand is not supported against a SelectCommand that does not return any key column information.... the button used to delete record in my project is button6 at the end of the code

I have an MS Access database that has a field called DeletedDate. I want to use a Delete statement that will delete the record(s) when DeleteDate is 30 days old or older. I have tried several different Delete statements but none seem to work properly. They will always delete some of the records, but will leave some records where either DeleteDate is older than 30 days or will delete recored where DeleteDate is not yet 30 days old. I have tried these using DeleteDate as a Text field and as a Date/Time field. Which should I use? These are the Delete Statements that I have used:
'sComm = "DELETE from Agents WHERE Deleted = 'Y' AND DeletedDate < " & System.DateTime.Now.Date.AddDays(-30) & " sComm =
what happens is i have a weekly salary table and once a week an administrator computes the salaries and it will be saved there, i want the delete code to delete the already saved record with the same Emp_ID as what i'm trying to save. my problem is i don't think the code i put deletes the record because it will still tell me that there is already an Emp_ID the same with what i'm trying to save..
so far this is my code..

I have an Access 2007 DB With 3 Tables I fill a form with information from 2 of the tables which works fine I then want to add a row to the third table with the information obtained from the form.(I know this may seem like duplicating data but there is a reason for doing this that I can explain if needed) This is where I am having the problem. I have tried several approaches with no success.The following code works fine I get no errors and it even says it added a new record but it does not. when I look at my access table there are no changes.Why can I get info from the DB but not Write back(yes I have the properties set to "update if newer"[code]...
