VBA + SQL Server-获取插入的最后一个ID

Question

Hope you can help - I'm having issues getting the last ID after INSERT.

So the environment - Access 2016, SQL Server and VBA

Dim db As DAO.Database
Dim RS As New ADODB.Recordset
Dim sql As String

I have theses declared and then private sub.

Private Sub CreateOrderHeader()
Dim CustomerID As Integer
Dim OrderDate As String
Dim OrderStatus As String
Dim OrderValue As Double
Dim OrderNotes As String
Dim OrderPostageID As String
Dim OrderAddressID As String
Dim OrderBatchID As Integer
Dim OrderPayment As String
Dim OrderCourierID As String
Dim OrderAgentID As Integer
Dim OrderOutstanding As Double

CustomerID = tbxCusID
OrderDate = Format(Now)
OrderStatus = "InProcess"
OrderValue = txtTotal.value
OrderNotes = tbxNotes.value
OrderPostageID = txtPostage.Column(0)

If tbxCustomerAddress = tbxDeliveryAddress Then
    OrderAddressID = 3 'default customers address
Else
    'NEED TO GET CUSTOMER ADDRESS TO DO
End If
OrderBatchID = cmbBatch.Column(0)
OrderPayment = sPayMethod
OrderCourierID = cbxShipping.Column(0)
OrderAgentID = 0
OrderOutstanding = txtTotal.value

 Dim testvar As String

sql = "INSERT INTO dbo_OrderHeader " _
      & "(OrdCusID, OrdDate, OrdStatus, OrdValue, OrdNotes, OrdPostageID, OrdDelAddID,OrdBatchID,OrdPaymentMethod, OrdCourierID,ordAgentID, OrdOutstanding,OrdSource) " _
      & " VALUES ('" & CustomerID & "' ,'" & OrderDate & "', '" & OrderStatus & "', '" & OrderValue & "', '" & OrderNotes & "', '" & OrderPostageID & "','" & OrderAddressID & "','" & OrderBatchID & "','" & OrderPayment & "','" & OrderCourierID & "','" & OrderAgentID & "','" & OrderOutstanding & "', 1)"



DoCmd.RunSQL (sql)

sql = "SELECT @@IDENTITY As IDT"
RS.Open sql, CurrentProject.Connection, adOpenStatic, adLockReadOnly
IDT = RS!IDT

MsgBox ("Succes - OrderHeader" & " '" & IDT & "'  ")
End Sub

I was expecting a result from this code:

sql = "SELECT @@IDENTITY As IDT"
RS.Open sql, CurrentProject.Connection, adOpenStatic, adLockReadOnly
IDT = RS!IDT

But that gives me "0" as result.

Can you help please.

Thanks

Answer 1

You can try this :

Set db = CurrentDB
db.Execute(sql)

IDT = db.OpenRecordset("SELECT @@IDENTITY")(0)
Set db = Nothing

NOTE

Don't execute your insert query like DoCmd.RunSQL (sql) Instead follow the above approach.
