SQL connection string in VBA (or linking tables)

[dougancil]

I have an application that I'm trying to finish in VBA, and as I've never written in it, it's a bit challenging to me. I've written some in VB but the syntax isn't the same between the two for some things. Essentially, here's the logic (or lack of) that I'm trying to accomplish with this task. This is a payroll program that was written by someone who is no longer with our organization. I am trying to finalize this, and realized that when reviewing it for finalization, that it was missing some components. Currently there is no way to create an audit trail for this program (which is why the timestamp is now coming into play.) Also, there is a value (the option group) that wasn't in the original version of this app. As far as the other two buttons on the first form, those perform calculations that end with a result when a user presses button #3 on the main form. What I'd like that 3rd button to also do is to open the second form, post the data from the results on the first form, show the option group with a submit button, when the user presses the submit button on form2, it appends a timestamp and the options group selection to the same table that the results of form1 were posted to. I'll go back through my code today and clean it up. I hope that that makes more sense now as to what I'm trying to achieve.

Step by step ... this is how the program should work:
1. User presses buttons 1, 2 and 3 on main form and gets a "sum" for the payroll for a specific time frame.
2. When the user presses the last button on main form, the form closes, the sum of the data is posted to a SQL database and a second form is opened.
3. The second form is a option group with 3 options, 1, 2, or 3 and a submit button.
4. The user chooses an option and presses the submit button on the second form, which then posts the option group result AND the timestamp to the SQL table. (the same SQL table where the information from the main form is posted)
5. Form 2 closes.

here is my code thus far: (main form)

Private Sub Command2_Click()

Dim rs As DAO.Recordset
Dim sqlStmt As String


 On Error GoTo Command2_Click_Err    'Error reporting on query code

DoCmd.OpenQuery "DeleteExecupayTable", acViewNormal, acEdit
DoCmd.OpenQuery "5_ExcepToExcupay", acViewNormal, acEdit
DoCmd.OpenQuery "7_SumToExecupay", acViewNormal, acEdit
DoCmd.OpenTable "6_1_Execupay", acViewNormal, acReadOnly
DoCmd.OpenForm "Form2", acNormal

Command2_Click_Exit:
Exit Sub

Command2_Click_Err:
 MsgBox "Open Query code failed. " & Error$
Resume Command2_Click_Exit

 DateStampError:
MsgBox "DateStamp code failed. " & Error$
Resume Command2_Click_Exit


 End Sub

Second form:

Option Compare Database
 Dim batchid As String


 Dim sConn As String
 sConn = "Provider='SQLOLEDB';Data Source='xxxxx';" & _
         "Initial Catalog='xxxxx';"

 Set sConn = New ADODB.Connection
 .Open

 On Error GoTo DateStampError 'Error reporting on DateStamp code
 sqlStmt = "Update timestamp FROM [Payroll]"
 Set rs = CurrentDb().OpenRecordset(sqlStmt)

 With rs
 If .RecordCount = 0 Then
    .AddNew 'For first time use before a record added
    .Fields("fldDate") = Date
    .Update
Else
    .MoveFirst
    .Edit
    .Fields("fldDate") = Date
    .Update
End If
End With
rs.Close
Set rs = Nothing

 SelectCase Me.Frame7.Value
 Case 1
 batchid = "='1'"
 Case 2
 batchid = "='2'"
 Case 3
 batchid = "='3'"
 End Select

 DateStampError:
 MsgBox "DateStamp code failed. " & Error$
 Resume Command2_Click_Exit
 End Sub

I'm not familiar with how to open a dataconnection string in VBA and also will this code fulfill my other requirements?

Thank you
