con.Open ();

mytrans =con.BeginTransaction();

cmd.Connection =con;

cmd.CommandText ="rfgetid";

cmd.CommandType =CommandType .StoredProcedure;

cmd.Transaction =mytrans ;

OracleParameter parameter_in=new OracleParameter("as_bm",OracleType.Char);

OracleParameter parameter_out=new OracleParameter ("as_sxh",OracleType .Number );

parameter_in.Direction =ParameterDirection .Input;

parameter_out.Direction=ParameterDirection .Output ;

parameter_in .Value =tblname.ToUpper();

cmd.Parameters .Add(parameter_in );

cmd.Parameters.Add(parameter_out);

cmd.ExecuteNonQuery();

mytrans .Commit();

return int.Parse(parameter_out .Value.ToString()) ;

}

catch(Exception er)

{

throw new Exception(er.Message);

mytrans .Rollback();

}

finally

{

cmd.Dispose ();
