postgresql - 通过 VBA 自动链接/刷新 MS Access 中的 ODBC 链接表

Question

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 程序吗？这是因为我正在寻找无 DSN 的连接，以使用户更轻松。

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
