Use Excel 2010 to read/write to a SQL Server 2008 database using stored procedures

Question

We have a SQL Server 2008 database that has stored procedures to handle reads/writes/etc. These procedures are used by a variety of applications internally.

The need ha

I ended up going with this approach using AD authentication. I used the example in this post for inspiration: http://www.eggheadcafe.com/community/sql-server/13/10141669/using-excel-to-update-data-on-ms-sql-tables.aspx

Note that these functions live in different areas of the Excel Workbook (Objects, Modules, This Workbook), but here's a quick reference.

I also have each of the columns that are FK validating against the tables they reference.

Here are some code samples:

Public aCon As New ADODB.Connection
Public aCmd As New ADODB.Command

Private Sub Workbook_Open()
  Application.EnableEvents = False
  PopulateSheet
  Application.EnableEvents = True
End Sub

Sub Connect()
  Dim sConn As String
  sConn = "Provider=SQLOLEDB;Trusted_Connection=Yes;Server=[SVR];Database=[DB]"
  With aCon
    .ConnectionString = sConn
    .CursorLocation = adUseClient
    .Open
  End With
  BuildProcs
End Sub

Sub BuildProcs()
  With aCmd
    .ActiveConnection = aCon
    .CommandType = adCmdStoredProc
    .CommandText = "[SPROC]"
    .Parameters.Append .CreateParameter("@in_EmployeeID", adInteger, adParamInput)
  End With

End Sub

Sub PopulateSheet()
  Dim n As Integer, r As Long

  Dim aCmdFetchEmployees As New ADODB.Command
  Dim aRstEmployees As New ADODB.Recordset

  If aCon.State = adStateClosed Then Connect

  With aCmdFetchEmployees
    .ActiveConnection = aCon
    .CommandType = adCmdStoredProc
    .CommandText = "[SPROC]"
    Set aRstEmployees = .Execute
  End With
  r = aRstEmployees.RecordCount

  Worksheets(1).Activate
  Application.ScreenUpdating = False
  Cells(2, 1).CopyFromRecordset aRstEmployees

  For n = 1 To aRstEmployees.Fields.Count
    Cells(1, n) = aRstEmployees(n - 1).Name
    Cells(1, n).EntireColumn.AutoFit
  Next
  Cells(1).EntireColumn.Hidden = True
End Sub

Private Sub Worksheet_Change(ByVal Target As Range)
  Dim cell As Range
  If aCon.State = adStateClosed Then Connect
    With aCmd
      .Parameters(0) = Cells(Target.Row, 1)
      .Parameters(1) = Cells(Target.Row, 4)
      .Parameters(2) = Cells(Target.Row, 5)
      .Parameters(3) = Cells(Target.Row, 6)
      .Parameters(4) = Cells(Target.Row, 7)
      .Parameters(5) = Cells(Target.Row, 8)
      .Parameters(6) = Cells(Target.Row, 10)
      .Parameters(7) = Cells(Target.Row, 11)
      .Parameters(8) = Cells(Target.Row, 12)
      .Parameters(9) = Cells(Target.Row, 13)
      .Parameters(10) = Cells(Target.Row, 14)
      .Parameters(11) = Cells(Target.Row, 15)
      .Parameters(12) = Cells(Target.Row, 16)
      .Execute , , adExecuteNoRecords
    End With

End Sub
