ms-access - MS Access - 如何通过修改表来更改链接表路径

Question

下面的查询允许我显示所有链接表及其对应的数据库路径

SELECT DISTINCTROW msysobjects.Name, msysobjects.Database, msysobjects.Connect
FROM msysobjects WHERE (((msysobjects.Type)=6 Or (msysobjects.Type) Like "dsn*")) ORDER BY msysobjects.Database;

输出

Name                    Database                             Connect
Account Transactions    C:\Users\Desktop\Database6_be.accdb 
Categories              C:\Users\Desktop\Database6_be.accdb 
Filters                 C:\Users\Desktop\Database6_be.accdb 
tblAuditLog             C:\Users\Desktop\Database6_be.accdb

当我为特定的 2 个表重命名数据库时，我无法修改路径。有什么办法可以通过修改表来修改链接表路径？

是的，您可以通过 VBA 或 GUI 来完成

通过 GUI (Access 2010):



您可以使用以下 VBA 子程序更改某些表上的连接字符串(您需要同时提供旧连接字符串和新连接字符串):

Public Sub ChangeConnection(OldStr As String, NewStr As String)
    Dim td As DAO.TableDef
    Dim db As DAO.Database
    Set db = CurrentDb()
    For Each td In db.TableDefs
        With td
            If .Connect = OldStr Then
                .Connect = NewStr
                .RefreshLink
            End If
        End With
    Next td
End Sub

或者，您可以使用以下子项来更改一个特定的表

Public Sub ChangeTableConnection(Tablename As String, NewStr As String)
    Dim td As DAO.TableDef
    Dim db As DAO.Database
    Set db = CurrentDb()
    Set td = db.TableDefs(Tablename)
    td.Connect = NewStr
    td.RefreshLink
End Sub
