Добрый день! Не подскажите как можно использовать 2 параметра для нескольких запросов?
К примеру у меня есть 2 запроса:

Dim commMMS1 As OracleCommand = New OracleCommand("select count(t.dialed) as COUNT_OUT, sum(t.duration) as SUMMA_D_OUT from calls_all t where t.lcal_lcal_id = 39 and t.start_time>=:PARAM1 and t.start_time<=to_date(:PARAM2)+1", conn)
commMMS1.CommandType = CommandType.Text

Dim commMMS2 As OracleCommand = New OracleCommand("select count(t.dialed) as COUNT_IN, sum(t.duration) as SUMMA_D_IN from calls_all t where t.lcal_lcal_id = 38 and t.start_time>=:PARAM1 and t.start_time<=to_date(:PARAM2)+1", conn)
commMMS2.CommandType = CommandType.Text

Помогите пожалуйста, очень нужно.
