新手提问:vb操作oracle的问题

我已经连接上了Oracle,代码如下:
Set OraDB = New ADODB.Connection
    OraConstr = "Provider=OraOLEDB.Oracle.1;Password=" & strOraPWD & ";User ID=" & strOraUser & ";Data Source=" & OraDBNetName & ";Persist   Security   Info=False"
    OraDB.CursorLocation = adUseServer

    OraDB.Open OraConstr现在我要执行下面的语句,怎么写?
GRANT "CONNECT" TO "User1";非常感谢!!
