All,
I am strugling with a problem for a while now. I am looking everywhere on the internet but did not find a solution yet. I have two tables, a main table (tbl_D_opp_prod_offer) and a detail table (tbl_D_opp_prod_offer_line). A user can select in a userform to create a duplicate of a record in the main form to start changing the new record. Also the associated records of the detail table should be duplicated. This is because sometimes it is faster for a user to grab another line as a template because it is already prefilled. I have simplified the below example.
Main table consists of:
Opp_ID = PK (autonumber)
Project (and several other fields)
Detail table consists of:
Opp_line_ID = PK (autonumber)
Opp_ID = FK (number)
Product (and several other fields)
I have used two ways, one with sql and one with recordsets. Both don't work. When I debug.print the sql route as a new query it works. So I don't get it where it goes wrong. The relationship has Enforce referential integrity, Cascade update and cascade delete. I really hope somebody could help me with this, I am loosing my hair ;-) Because I have stored it in Form class object of the main form, could this be an issue? Or a key violation? How can I change this?
The code I have for the SQL solution:
Public Function duplicate()
'Find selected record
DoCmd.SearchForRecord , , , "[Project_ID] = " & "'" & [Forms]![Frm_Opp_prod_offer]! [lst_Edit_project_ID] & "'"
Dim OldId As Integer, NewId As Integer
' Read old ID
OldId = Me.Opp_ID
' copy main table records to new record
DoCmd.RunCommand acCmdSelectRecord
DoCmd.RunCommand acCmdCopy
DoCmd.RunCommand acCmdRecordsGoToNew
DoCmd.RunCommand acCmdSelectRecord
DoCmd.RunCommand acCmdPaste
' Read new ID
NewId = Me.Opp_ID
' Copy all records from old ID to new ID
S = "INSERT INTO [tbl_D_opp_prod_offer_line] (Opp_ID, Product) " & _
"SELECT " & NewId & " As Opp_ID, Product " & _
"FROM [tbl_D_opp_prod_offer_line] WHERE Opp_ID = " & OldId
Debug.Print S
Stop
' Hit Ctrl+G, copy SQL from Immediate Window to a new query
CurrentDb.Execute S, dbFailOnError
' Load copied records
Me!Frm_Opp_prod_offer_line.Form.Requery
End Function
`
The solution via Recordset:
Sub method2()
Dim rstSource As DAO.Recordset
Dim rstInsert As DAO.Recordset
Dim fld As DAO.Field
Dim strSQL As String
Dim lngLoop As Long
Dim lngCount As Long
Dim OldId As Integer, NewId As Integer
'Beginning is same
'Find selected record
DoCmd.SearchForRecord , , , "[Project_ID] = " & "'" & [Forms]![Frm_Opp_prod_offer]![lst_Edit_project_ID] & "'"
' Read old ID
OldId = Me.Opp_ID
' copy main table records to new record
DoCmd.RunCommand acCmdSelectRecord
DoCmd.RunCommand acCmdCopy
DoCmd.RunCommand acCmdRecordsGoToNew
DoCmd.RunCommand acCmdSelectRecord
DoCmd.RunCommand acCmdPaste
' Read new ID
NewId = Me.Opp_ID
strSQL = "SELECT * FROM tbl_D_opp_prod_offer_line WHERE Opp_ID = " & OldId
' Change this to the RecordsetClone of the subform.
Set rstInsert = CurrentDb.OpenRecordset(strSQL)
Set rstSource = rstInsert.Clone
With rstSource
lngCount = .RecordCount
For lngLoop = 1 To lngCount
With rstInsert
.AddNew
For Each fld In rstSource.Fields
With fld
If .Attributes And dbAutoIncrField Then
' Skip Autonumber or GUID field.
If .Name = "Opp_ID" Then ' Name of FK.
rstInsert.Fields(.Name).Value = NewId ' The new ID of the parent.
Else
' Copy field content.
rstInsert.Fields(.Name).Value = .Value
End If
End If
End With
Next
.Update
End With
.MoveNext
Next
rstInsert.Close
.Close
End With
Set rstInsert = Nothing
Set rstSource = Nothing
End Sub
