con.execute "exec sp"

需要参数返回的如下
该范例使用 Append 和 CreateParameter 方法执行具有输入参数的存储过程。

Public Sub AppendX()

Dim cnn1 As ADODB.Connection
Dim cmdByRoyalty As ADODB.Command
Dim prmByRoyalty As ADODB.Parameter
Dim rstByRoyalty As ADODB.Recordset
Dim rstAuthors As ADODB.Recordset
Dim intRoyalty As Integer
Dim strAuthorID As String
Dim strCnn As String

' 打开连接。
Set cnn1 = New ADODB.Connection
strCnn = "Provider=sqloledb;" & _
"Data Source=srv;Initial Catalog=pubs;User Id=sa;Password=; "
cnn1.Open strCnn
cnn1.CursorLocation = adUseClient

' 使用一个参数打开命令对象。
Set cmdByRoyalty = New ADODB.Command
cmdByRoyalty.CommandText = "byroyalty"
cmdByRoyalty.CommandType = adCmdStoredProc

' 获取参数值并追加参数。
intRoyalty = Trim(InputBox("Enter royalty:"))
Set prmByRoyalty = cmdByRoyalty.CreateParameter("percentage", _
adInteger, adParamInput)
cmdByRoyalty.Parameters.Append prmByRoyalty
prmByRoyalty.Value = intRoyalty

' 通过执行命令创建记录集。
Set cmdByRoyalty.ActiveConnection = cnn1
Set rstByRoyalty = cmdByRoyalty.Execute

' 打开 Authors 表以获取作者姓名进行显示。
Set rstAuthors = New ADODB.Recordset
rstAuthors.Open "authors", cnn1, , , adCmdTable

' 打印记录集中的当前数据，从 Authors 表中添加作者姓名。
Debug.Print "Authors with " & intRoyalty & " percent royalty"
Do While Not rstByRoyalty.EOF
strAuthorID = rstByRoyalty!au_id
Debug.Print " " & rstByRoyalty!au_id & ", ";
rstAuthors.Filter = "au_id = '" & strAuthorID & "'"
Debug.Print rstAuthors!au_fname & " " & rstAuthors!au_lname
rstByRoyalty.MoveNext
Loop

rstByRoyalty.Close
rstAuthors.Close
cnn1.Close

End Sub
