组合框的行来源中只能写存储过程名，无法加上参数，我们这里用值列表绕过次限制
Public Sub CreateP2Procedure()
'创建本示例需要用的参数存储过程
'表名和字段名请按你的实际情况填写
Dim strSQL As String
strSQL = "Create Procedure procCreateMyList(@P1 int =0,@P2 nvarChar(50)='') As SELECT field1 FROM tblTable1 WHERE field2 = @P1 and field3 like @P2"
CurrentProject.Connection.Execute strSQL
End Sub
Private Sub Form_Open(Cancel As Integer)
'将本过程放在窗体的打开事件中，设定组合框的行来源
Me.ComboBox.RowSourceType = "value list"
Me.ComboBox.RowSource = GetRowSource("p2", 155, "%")
End Sub
Public Function GetRowSource(ByVal strCommandText As String, _
Optional ByVal varP1, _
Optional ByVal varP2, _
Optional ByVal varP3)
'本函数作用：
'将存储过程的执行结果转换为用分号分隔的值列表
'现在参数是 3 个，可以更改一下，用数组来代替
Dim Rs As New ADODB.Recordset
Dim cmd As New ADODB.Command
Dim prm As ADODB.Parameter
