Question

是否有人知道在MS-Access 2010中自动链接和刷新Postgres链接表（通过ODBC）的VBA过程？这是因为我正在寻找一种无DSN连接，以方便用户使用。

Answer 1

以下VBA代码将创建具有无DSN连接的PostgreSQL链接表...

Sub linkTo_PostgreSQL()
    createLinkedTable_PostgreSQL "public.table1"
    ' repeat as necessary...
End Sub

Sub createLinkedTable_PostgreSQL(PostgreSQL_tableName As String)
    Dim cdb As DAO.Database, tbd As DAO.TableDef
    Set cdb = CurrentDb
    Set tbd = New DAO.TableDef

    tbd.Connect = "ODBC;Driver={PostgreSQL ODBC Driver(UNICODE)};Server=localhost;Port=5432;Database=linkedDB;Uid=pgUser1;Pwd=pgUser1password;"
    tbd.SourceTableName = PostgreSQL_tableName
    tbd.Name = Replace(PostgreSQL_tableName, ".", "_", 1, -1, vbTextCompare)  ' e.g. "public.table1"->"public_table1"
    tbd.Attributes = dbAttachSavePWD

    cdb.TableDefs.Append tbd
    Set tbd = Nothing
    Set cdb = Nothing
End Sub

以下代码将刷新任何现有PostgreSQL链接表的链接：

Sub refreshLinked_PostgreSQL()
    Dim cdb As DAO.Database, tbd As DAO.TableDef
    Set cdb = CurrentDb
    For Each tbd In cdb.TableDefs
        If tbd.Connect Like "ODBC;Driver={PostgreSQL*" Then
            Debug.Print "Refreshing [" & tbd.Name & "] ..."
            tbd.RefreshLink
        End If
    Next
    Debug.Print "Done."
    Set tbd = Nothing
    Set cdb = Nothing
End Sub

通过VBA在MS Access中自动链接/刷新ODBC链接表
