ParentCatalog 范例

目录

如下代码演示如何使用 ParentCatalog 属性，在将表追加到目录之前访问指定提供者的属性。

Sub SetAllowZeroLength()   Dim cnn As New ADODB.Connection
   Dim cat As New ADOX.Catalog
   Dim tbl As New ADOX.Table
   Dim col As New ADOX.Column   cnn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
      "Data Source= c:\Program Files\" & _
      "Microsoft Office\Office\Samples\Northwind.mdb;"
   Set cat.ActiveConnection = cnn
   tbl.Name = "MyTable"
   tbl.Columns.Append "Column1", adInteger
   Set col.ParentCatalog = cat
   col.Name = "Column2"
   col.Type = adVarWChar
   col.Properties("Jet OLEDB:Allow Zero Length") = True
   tbl.Columns.Append col
   cat.Tables.Append tblEnd Sub
