请问高手: 能否用代码建立表之间的各种关系?

不知可否用代码实现如下功能？

1、删除原有表之间的关系。

2、建立新的关系。

谢谢指点……

APPEND 語法
ADO
Sub CreateRelation()
Dim cat As ADOX.Catalog
Dim tbl As ADOX.Table
Dim fk As ADOX.Key

Set cat = New ADOX.Catalog
cat.ActiveConnection = CurrentProject.Connection

Set tbl = cat.Tables("tblPeople")

Set fk = New ADOX.Key
fk.Name = "

eopleFood"
fk.Type = adKeyForeign
fk.RelatedTable = "tblFoods"

fk.Columns.Append "FoodId"
fk.Columns("FoodID").RelatedColumn = "FoodID"
tbl.Keys.Append fk

Set cat = Nothing
Set tbl = Nothing
Set fk = Nothing
End Sub

DOA
Sub CreateRelation()
Dim db As Database
Dim rel As Relation
Dim fld As Field

Set db = CurrentDb
Set rel = db.CreateRelation()

With rel
.Name = "

eopleFood"
      .Table = "tblFoods"
      .ForeignTable = "tblPeople"
      .Attributes = dbRelationDeleteCascade
End With

Set fld = rel.CreateField("FoodID")
fld.ForeignName = "FoodID"
rel.Fields.Append fld
db.Relations.Append rel
End Sub
