ms-access - 是否可以修改 Access 加密后端的结构？

Question

我有一个拆分数据库。尝试使用前端，我能够使用 VBA 将字段添加到链接后端的表中，直到我使用密码加密后端。

是否仍然可以在前端使用 VBA 向后端表中添加字段，而无需手动解密后端？

感谢您的回复。

它应该是。试试这些笔记：

Sub AlterDB()
    Dim db As DAO.Database
    Dim sDB As String
    Dim tdf As TableDef
    Dim fld As Field

    ''Encrypted
    sDB = "Z:\Docs\Test.enc"

    ''http://msdn.microsoft.com/en-us/library/office/ff193474.aspx
    ''Password is case sensitive
    Set db = OpenDatabase(sDB, False, False, "MS Access;PWD=pW")

    ''Option with tabledef
    ''The table is currently closed
    Set tdf = db.TableDefs("table1")
    Set fld = tdf.CreateField("NewField", dbText, 20)
    tdf.Fields.Append fld

    ''Option with DDL
    ssql = "ALTER TABLE table1 ADD COLUMN AnotherNew Int"
    db.Execute ssql, dbFailOnError

End Sub

Sub ListFields()
    sDB = "Z:\Docs\Test.enc"
    Set db = OpenDatabase(sDB, False, False, "MS Access;PWD=FB")

    Set tdf = db.TableDefs("table1")
    For Each f In tdf.Fields
        Debug.Print f.Name
    Next

End Sub
