c# - DateTime 格式错误 C# , Oracle

Question

在我的应用程序中，我捕获了一个“时间戳”。我稍后在调用存储过程时使用此时间戳。目前我收到错误:

ORA-01830: date format picture ends before converting entire inputstring ORA-06512: at line 2

我需要小时、分钟和秒，因为表中的列必须是唯一的。

这是我获取日期时间的方式:

private void getDate()
    {
        conn.Open();
        string query;
        query = "select to_char(sysdate, 'dd/mon/yyyy hh24:mi:ss') as CurrentTime from dual";
        OracleCommand cmd = new OracleCommand(query, conn);
        OracleDataReader dr = cmd.ExecuteReader();
        dr.Read();
        text = dr[0].ToString();
        dr.Close();
        conn.Close();
    }

我是这样调用程序的:

        OracleCommand cmd = new OracleCommand();
        cmd.Connection = conn;
        conn.Open();
        OracleTransaction trans = conn.BeginTransaction();
        cmd.CommandTimeout = 0;
        cmd.CommandText = "dc.hhrcv_insert_intrnl_audit_scn";
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.Add("pn_pallet_id", OracleDbType.Number).Value = palletid;
        cmd.Parameters.Add("pn_emp_id_no", OracleDbType.Number).Value = empid;
        cmd.Parameters.Add("pd_intrnl_audit_scan_datetime", OracleDbType.VarChar).Value = text;
        cmd.Parameters.Add("pn_company_id_no", OracleDbType.VarChar).Value = companyIdNo2;
        cmd.Parameters.Add("pn_order_no", OracleDbType.Number).Value = orderNo2;
        cmd.Parameters.Add("pn_carton_code", OracleDbType.Number).Value = carton_Code2;
        cmd.Parameters.Add("pn_no_of_full_carton", OracleDbType.Number).Value = txtNoOfCartons.Text;
        cmd.Parameters.Add("pn_no_of_packs", OracleDbType.Number).Value = txtNoOfPacks.Text;
        cmd.Parameters.Add(new OracleParameter("pv_error", OracleDbType.VarChar));
        cmd.Parameters["pv_error"].Direction = ParameterDirection.Output;
        string pv_error;
        cmd.ExecuteNonQuery();
        pv_error = cmd.Parameters["pv_error"].Value.ToString();
        if (pv_error.ToString() == "")
        {
            trans.Commit();
            frmMsgAudit ms = new frmMsgAudit(empid,palletid,orderno,text);
            ms.Show();
            this.Hide();
        }
        else
        {
            trans.Rollback();
            MessageBox.Show("" + pv_error, "Error");
        }
        conn.Close();

获取错误:

cmd.ExecuteNonQuery();

ORA-01830: date format picture ends before converting entire inputstring ORA-06512: at line 2

感谢大家的快速回复!

grrr.. 我真的需要坐下来一步步走完所有事情!无论如何，这就是问题所在:

在我的存储过程中:

...
begin
insert into dc_internal_audit_scan (pallet_id_no,
                                    internal_audit_scan_emp,
                                    internal_audit_scan_datetime,
                                    company_id_no,
                                    order_no,
                                    carton_code,
                                    no_of_full_cartons,
                                    no_of_packs,
                                    last_update_datetime,
                                    username)      
                            values (ln_pallet_id_no,
                                    pn_emp_id_no,
                                    **pd_intrnl_audit_scan_datetime,**
                                    pn_company_id_no,
                                    pn_order_no,
                                    pv_carton_code,
                                    pn_no_of_full_cartons,
                                    pn_no_of_packs,
                                    sysdate,
                                    lv_emp_username);
end; 

现在:

...
begin
insert into dc_internal_audit_scan (pallet_id_no,
                                    internal_audit_scan_emp,
                                    internal_audit_scan_datetime,
                                    company_id_no,
                                    order_no,
                                    carton_code,
                                    no_of_full_cartons,
                                    no_of_packs,
                                    last_update_datetime,
                                    username)      
                            values (ln_pallet_id_no,
                                    pn_emp_id_no,
                                    **TO_DATE(pd_intrnl_audit_scan_datetime,'dd/mon/yyyy hh24:mi:ss'),**
                                    pn_company_id_no,
                                    pn_order_no,
                                    pv_carton_code,
                                    pn_no_of_full_cartons,
                                    pn_no_of_packs,
                                    sysdate,
                                    lv_emp_username);
end; 

TO_DATE(pd_intrnl_audit_scan_datetime,'dd/mon/yyyy hh24:mi:ss')

谢谢
