上週我剛剛寫了一個article，詳細介紹了將SQL數據庫中的所有錶快速鏈接到Access的方法。以下是一些有助於解決的Access方法。閱讀文章以獲取使用它的更多說明。
您將需要引用Microsoft ActiveX Data Objects庫。
Sub LinkAllTables(Server As String, database As String, OverwriteIfExists As Boolean)
'Usage Example (link all tables in database "SQLDB" on SQL Server Instance SQO01, overwriting any existing linked tables.
'linkalltables "SQL01","SQLDB", true
'This will also update the link if the underlying table definition has been modified.
Dim rsTableList As New ADODB.Recordset
Dim sqlTableList As String
sqlTableList = "SELECT [name] as tablename FROM sysObjects WHERE (type = 'U')"
rsTableList.Open sqlTableList, BuildSQLConnectionString(Server, database)
While Not rsTableList.EOF
If LinkTable(rsTableList("tableName"), Server, database, rsTableList("tableName"), OverwriteIfExists) Then
Debug.Print "Linked: " & rsTableList("tableName")
End If
rsTableList.MoveNext
Wend
rsTableList.Close
Debug.Print "Done."
End Sub
Function LinkTable(LinkedTableAlias As String, Server As String, database As String, SourceTableName As String, OverwriteIfExists As Boolean)
'This method will also update the link if the underlying table definition has been modified.
'The overwrite parameter will cause it to re-map/refresh the link for LinktedTable Alias, but only if it was already a linked table.
' it will not overwrite an existing query or local table with the name specified in LinkedTableAlias.
'Links to a SQL Server table without the need to set up a DSN in the ODBC Console.
Dim dbsCurrent As database
Dim tdfLinked As TableDef
' Open a database to which a linked table can be appended.
Set dbsCurrent = CurrentDb()
'Check for and deal with the scenario ofthe table alias already existing
If TableNameInUse(LinkedTableAlias) Then
If (Not OverwriteIfExists) Then
Debug.Print "Can't use name '" + LinkedTableAlias + "' because it would overwrite existing table."
Exit Function
End If
'delete existing table, but only if it is a linked table
If IsLinkedTable(LinkedTableAlias) Then
dbsCurrent.TableDefs.Delete LinkedTableAlias
dbsCurrent.TableDefs.Refresh
Else

Else
Debug.Print "Can't link table '" + SourceTableName + "' because it contains too many indexes for Access to handle. Create a view named '" & "vw" & SourceTableName & "' that selects all rows/columns from '" & SourceTableName & "' and try again to circumvent this."

試過了，mdb中的鏈接包含我的憑據和我的權限。 – 2009-10-15 17:14:37
用該用戶的憑據構建字符串，而不是你的！ – 2009-10-15 18:17:34
