Use Access to Connect to SQL Server

G

I recently purchased the SQL Server 2000 Developer Edition. How would I
configure Access to be able to connect to the Northwind database which exists
in SQL Server ?

There are 2 ways depending on the version of Access you have.
A2000 and newer can connect directly to SQL Server using an Access Project
file format.
Just input a connection string in the dialog and it works.

The other more common way is to use linked tables.
First create an ODBC DSN to the SQL Server.
Then in Access use:
File, Get External Data, Link
use the ODBC Data Source in Files oF Type

Select the tables you want to link and you should be able to see the data in
them.

The method above links the tables with a prefix of dbo_ which is very
annoying.
I use code to do the linking and I ensure the prefix is not present.

=======================================

I use this procedure to re-create links to SQL Server.
====================================================
For Jet re-linking code see:
http://www.mvps.org/access/tables/tbl0009.htm
====================================================
(This eliminates the need to re-name all the tables to strip out dbo_ and it
allows you to point to different versions of the same database easily.)
There is a local Access table (tblODBCTables) that contains the table names
I want to link to on the Server.
Note: the source table name needs the dbo. prefix which is in the code. The
linked table name usualy omits this. .

Public Sub LinkSQLServerTables(strDSN As String, strDatabase)
On Error GoTo Err_LinkSQLServerTables

Dim dbs As Database, rs As Recordset, tdfAccess As TableDef
Dim dbsODBC As Database, strConnect As String

If strDSN = "" Then
MsgBox "You must supply a DSN in order to link tables."
Exit Sub
Else
strConnect = "ODBC;DSN=" & strDSN & ";UID=User;PWD=password;DATABASE=" &
strDatabase & ";"
End If

SysCmd acSysCmdSetStatus, "Connecting to SQL Server..."

Call DeleteODBCTableNames

Set dbs = CurrentDb
Set rs = dbs.OpenRecordset("tblODBCTables")
Set dbsODBC = OpenDatabase("", False, False, strConnect)

Do While Not rs.EOF
Set tdfAccess = dbs.CreateTableDef(rs![LinkTablename], dbAttachSavePWD)
tdfAccess.Connect = dbsODBC.Connect
tdfAccess.SourceTableName = dbsODBC.TableDefs("dbo." &
rs![LinkTablename]).Name
dbs.TableDefs.Append tdfAccess
rs.MoveNext
Loop

rs.Close
Set rs = Nothing
Set dbsODBC = Nothing
Set dbs = Nothing

Exit_LinkSQLServerTables:
SysCmd acSysCmdClearStatus
Exit Sub

Err_LinkSQLServerTables:
MsgBox ("Error # " & Str(Err.Number) & " was generated by " & Err.Source
& Chr(13) & Err.Description)
Resume Exit_LinkSQLServerTables

End Sub


'This procedure deletes all linked ODBC table names in an mdb.
Public Sub DeleteODBCTableNames()
On Error GoTo Err_DeleteODBCTableNames

Dim dbs As Database, tdf As TableDef, I As Integer
Set dbs = CurrentDb
For I = dbs.TableDefs.Count - 1 To 0 Step -1
Set tdf = dbs.TableDefs(I)
If (tdf.Attributes And dbAttachedODBC) Then
dbs.TableDefs.Delete (tdf.Name)
End If
Next I

dbs.Close
Set dbs = Nothing

Exit_DeleteODBCTableNames:
Exit Sub

Err_DeleteODBCTableNames:
MsgBox ("Error # " & Str(Err.Number) & " was generated by " & Err.Source
& Chr(13) & Err.Description)
Resume Exit_DeleteODBCTableNames

End Sub
