有关C#中使用oracle sequence的问题求解？

[cshzxq2000]

代码如下，请指点下错在哪里，应该怎么写，谢谢！

 string sqlstr = "insert into symptom(ID,symptomCode,symptomName) values (HIBERNATE_SEQUENCE.nextval,:symptomCode,:symptomName); ";
          string oraclestr = "User ID=CDR;Password=CDR;Data Source=(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST=127.0.0.1)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=orcl)))";

         conn = new OracleConnection(oraclestr);
         conn.Open();
         OracleCommand cmd = new OracleCommand();
         cmd.Connection = conn;
         cmd.CommandText = sqlstr;
         cmd.CommandType = CommandType.Text;
         cmd.Parameters.Add("symptomCode", OracleType.VarChar, 255).Value = "112";
         cmd.Parameters.Add("symptomName", OracleType.VarChar, 255).Value = "cc";     
         cmd.ExecuteNonQuery();
