Question

这是我的程序，它适用于PL / SQL Developer：

create or replace procedure CHECK_INFO_INS
(
    p_id_aircraft IN VARCHAR2,           
    p_id_check_type IN NUMBER,     
    p_last_check   IN DATE,             
    p_next_check   IN DATE,             
    p_expectedcost IN NUMBER,                             
    p_id_currency  IN NUMBER,
    p_currency_rate IN NUMBER                         
)             
is
Rate number;
CurrentDate Date;
catID Checkcategories.Id%type;
begin
select C.ID into catID from CHECKCATEGORIES C WHERE C.NAME='C' and C.CHECKTYPEID = p_id_check_type;

  Rate:=round(p_expectedcost/MONTHS_BETWEEN(p_next_check, p_last_check),3)*p_currency_rate;
  CurrentDate := SYSDATE;
  INSERT INTO CHECK_INFO
  (
      id_check_info,            
      id_aircraft,              
      id_check_categories,      
      last_check,               
      next_check,              
      expectedcost,             
      is_accumulation_complited,
      rate,                     
      id_currency,              
      current_date,             
      monthes_between,
      CURENCY_RATE             
 )
  values
  (
    CHECKS_INFO_SEQ.NEXTVAL,
    p_id_aircraft,
    catID,
    p_last_check,
    p_next_check,
    p_expectedcost,
    0,
    Rate,
    p_id_currency,
    CurrentDate,
    round(MONTHS_BETWEEN(p_next_check, p_last_check),1),
    p_currency_rate
  );
  commit;
    EXCEPTION
    WHEN OTHERS
    THEN
      DBMS_OUTPUT.PUT_LINE(SQLERRM);
      ROLLBACK;
end CHECK_INFO_INS;

这是我的C＃代码：

        decimal expectedCost = Decimal.Parse(ExpCostTextBox.Text);
        DateTime lastCheck = DateTime.Parse(LastCheckdateTimePicker.Text);
        DateTime nextCheck = DateTime.Parse(NextCheckdateTimePicker.Text);
        int checkType = int.Parse(ChCmbx.SelectedValue.ToString());
        string AirCraft = AirCraftCmbx.SelectedValue.ToString();
        int curID = int.Parse(CurrComboBox.SelectedValue.ToString());
        decimal curRate = decimal.Parse(CurRateTextBox.Text.Replace('.',','));


        con = new OracleConnection(conStr);
        con.Open();
        cmd = con.CreateCommand();
        cmd.BindByName = true;
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.CommandText = schema_name + ".CHECK_INFO_INS";

        cmd.Parameters.Add("p_id_aircraft", OracleDbType.NVarchar2, AirCraft, ParameterDirection.Input);
        cmd.Parameters.Add("p_id_check_categories", OracleDbType.Int32, checkType, ParameterDirection.Input);
        cmd.Parameters.Add("lastCheck", OracleDbType.Date, lastCheck, ParameterDirection.Input);
        cmd.Parameters.Add("nextCheck", OracleDbType.Date, nextCheck, ParameterDirection.Input);
        cmd.Parameters.Add("p_expectedcost", OracleDbType.Decimal, expectedCost, ParameterDirection.Input);
        cmd.Parameters.Add("p_id_currency", OracleDbType.Int32, curID, ParameterDirection.Input);
        cmd.Parameters.Add("p_currency_rate", OracleDbType.Decimal, curRate, ParameterDirection.Input);
        cmd.ExecuteNonQuery();

它在executeNonQuery行上抛出异常：

ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'CHECK_INFO_INS'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

我尝试重新创建程序，但它没有用。我的C＃代码出了什么问题？

Answer 1

我对Oracle不是很熟悉，但是您程序中的第二个参数名为＆＃34; p_id_check_type＆＃34;而当您将参数添加到参数集合时，您使用名称＆＃34; p_id_check_categories＆＃34;。可能是你的问题吗？

Answer 2

Oracle参数名称应以参数列表和SQL语句中的冒号开头，如:p_currency_rate。

Answer 3

克里斯是对的，

您在调用存储过程时使用了错误的参数名称。

所以在你的电话中：

   cmd.Parameters.Add("p_id_check_categories", OracleDbType.Int32, checkType, ParameterDirection.Input);
cmd.Parameters.Add("lastCheck", OracleDbType.Date, lastCheck, ParameterDirection.Input);
        cmd.Parameters.Add("nextCheck", OracleDbType.Date, nextCheck, ParameterDirection.Input);

它应该与存储过程中的参数值相同，如下所示：

    cmd.Parameters.Add("p_id_check_type", OracleDbType.Int32, checkType, ParameterDirection.Input);
cmd.Parameters.Add("p_last_check", OracleDbType.Date, lastCheck, ParameterDirection.Input);
        cmd.Parameters.Add("p_next_check", OracleDbType.Date, nextCheck, ParameterDirection.Input);

至少每当我遇到这个问题时：

PLS-00306：调用的参数的数量或类型错误＆＃39; CHECK_INFO_INS＆＃39;

这通常是我遇到此问题的原因，除非我的参数顺序错误。

ORA-06550：调用'CHECK_INFO_INS'时参数的数量或类型错误
