How to insert into table from subform using SQL statement in VBA with Where clause that has two conditions.

Greetings Experts:

I'm getting an error when the user clicks on the Edit button on the frmEvent subform. I'm trying to insert the eventdate from the subform into another table.
I haven't used sql much in VBA so I'm sure I'm missing something critical. Here is my code and the example is attached.

Private Sub cmdEdit_Click()
On Error GoTo Err_Handler

    Dim strWhere As String
    If IsNull(Me.EventID) Or IsNull(Me.InstanceID) Then
        MsgBox "Unable to determine the entry to edit.", vbExclamation, "Cannot edit."
        strWhere = "(EventID = " & Nz(Me.EventID, 0) & ") AND (InstanceID = " & Nz(Me.InstanceID, 0) & ")"
        DoCmd.RunSQL "Insert INTO tblEventException (OrigEventDate) Values Forms!frmEvent!frmEventSub!EventDate WHERE = strWhere"
        DoCmd.OpenForm "frmEventException", WhereCondition:=strWhere, WindowMode:=acDialog
    End If
    Exit Sub
    Call LogError(Err.Number, Err.Description, conMod & ".cmdEdit_Click")
    Resume Exit_Handler
End Sub

Since you are trying to UPDATE a record, you need an update query, not an INSERT query.

rather than:
DoCmd.RunSQL "Insert INTO tblEventException (OrigEventDate) Values Forms!frmEvent!frmEventSub!EventDate WHERE = strWhere"

Open in new window

Dim strSQL as string
strSQL = "UPDATE tblEventException " _
       & "SET OrigEventDate = #" & Forms!frmEvent!frmEventSub!EventDate & "# " _
       & "WHERE " & strWhere
debug.print strsql 
currentdb.Execute strsql, dbfailonerror

Open in new window

This will allow you to debug your code and avoid the warning messages that you get with the RunSQL method.

Dale also made syntax corrections which he didn't mention.  You would have seen the syntax error if you had used the good technique of building the string into a variable first rather than trying to execute the string.
