如何在VB.NET Windows应用程序中创建ADODB断开连接的记录集？

我正在使用与Sybase数据库的OLEDB连接,ADODB.dll文件版本为7.10.6070.0(来自Sybase 12.5软件包).我需要能够打开连接,使用命令对象从存储过程填充记录集,然后关闭连接并传回断开连接的记录集.到目前为止,我的尝试都失败了,因为每次关闭连接时,我的记录集也会关闭(这意味着它没有断开连接).

是否有一个属性我必须在某处设置以指示记录集应该断开连接？我无法设置Recordset.ActiveConnection = False,因为我得到一个异常(“无法更改具有Command对象作为其来源的Recordset对象的ActiveConnection属性.”).我设置Command.ActiveConnection = False,但是一旦我关闭连接对象,就不会停止记录集关闭.

Dim conn as New ADODB.Connection()
conn.Open("connectionString","UserID","Password")
Dim cmd as New ADODB.Command()
' Set some parameters on the command.
cmd.ActiveConnection = conn
cmd.CommandText = "StoredProcedureName"
cmd.CommandType = ADODB.CommandTypeEnum.adCmdStoredProc
Dim rs as New ADODB.Recordset()
rs.Open(cmd)
Dim clonedRS as ADODB.Recordset = rs.Clone()  ' one attempt to disconnect recordset
rs.Close()  ' Does not close cloned recordset
cmd.ActiveConnection = Nothing   ' another try at disconnecting recordset
conn.Close()  ' Always closes the recordset,even the cloned one
return clonedRS  ' Sadly,this is closed now.

Dim conn as New ADODB.Connection()
conn.Open("connectionString","Password")
Dim cmd as New ADODB.Command()
' Set some parameters on the command.
cmd.ActiveConnection = conn
cmd.CommandText = "StoredProcedureName"
cmd.CommandType = ADODB.CommandTypeEnum.adCmdStoredProc

Dim rs As ADODB.Recordset

With rs
    .CursorLocation = adUseClient
    .Open cmd,CursorType:=adOpenStatic,Options:=adCmdStoredProc
    Set .ActiveConnection = Nothing
End With

Dim clonedRS As ADODB.Recordset = rs

Set cmd = Nothing

conn.Close()
rs.Close()
Set conn = Nothing
Set rs = Nothing

Return clonedRS
