在ado.net中实现oracle存储过程调用两种方式

String or=ConfigurationManager.ConnectionStrings["conn"].ToString();

OracleConnection oc = new OracleConnection(or);

oc.Open();

OracleCommand om = oc.CreateCommand();

om.CommandType = CommandType.StoredProcedure;

om.CommandText = "proc2";

om.Parameters.Add("v_id", OracleType.Number).Direction = ParameterDirection.Input;

om.Parameters["v_id"].Value = this.TextBox2.Text.Trim();

om.Parameters.Add("v_name", OracleType.NVarChar).Direction = ParameterDirection.Input;

om.Parameters["v_name"].Value = this.TextBox3.Text.Trim(); om.ExecuteNonQuery();

oc.Close();

String or=ConfigurationManager.ConnectionStrings["conn"].ToString();

OracleConnection oc = new OracleConnection(or);

oc.Open();

OracleCommand om = oc.CreateCommand();

om.CommandType = CommandType.Text;

om.CommandText = "call PRO_USER_BOSS(a,b,c)";//a,b,c为传入的存储过程参数及值

om.ExecuteNonQuery(); oc.Close();
