如下代码演示怎样使用 Command 对象和 Procedures 集合 Append 方法,在基本数据源中创建新的过程。
Sub CreateProcedure()
Dim cnn As New ADODB.Connection
Dim cmd As New ADODB.Command
Dim prm As ADODB.Parameter
Dim cat As New ADOX.Catalog
' 打开连接
cnn.Open _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\Program Files\Microsoft Office\" & _
"Office\Samples\Northwind.mdb;"
' 创建参数化命令(Jet 指定)
Set cmd.ActiveConnection = cnn
cmd.CommandText = "PARAMETERS [CustId] Text;" & _
"Select * From Customers Where CustomerId = [CustId]"
' 打开目录
Set cat.ActiveConnection = cnn
' 创建新过程
cat.Procedures.Append "CustomerById", cmd
End Sub
