Question

I have a table named CREATED_AT I wrote a query and receive the response like this : Score D 27 01 17 02 80 03 55 06

this is my query :

SELECT SUM(AMOUNT) as scores,to_char(CREATED_AT, 'MONTH') as  d  
FROM C_SCORES 
WHERE USER_ID =201 and to_char(CREATED_AT, 'YYYY') ='1398' 
GROUP BY to_char(CREATED_AT, 'MONTH');

the entity code is :

    public class ScoreCategorizeWithMonth {

        private int Scores;
        private int month;
    private String monthfa;


 public String getMonthfa() {
        switch (month) {
            case 1:
                monthfa = "فروردین";
                break;
            case 2:
                monthfa = "اردیبهشت";
                break;
            case 3:
                monthfa = "خرداد";
                break;
            case 4:
                monthfa = "تیر";
                break;
            case 5:
                monthfa = "مرداد";
                break;
            case 6:
                monthfa = "شهریور";
                break;
            case 7:
                monthfa = "مهر";
                break;
            case 8:
                monthfa = "آبان";
                break;
            case 9:
                monthfa = "آذر";
                break;
            case 10:
                monthfa = "دی";
                break;
            case 11:
                monthfa = "بهمن";
                break;
            case 12:
                monthfa = "اسفند";
            default:
                monthfa = "";
        }



        return monthfa;
    }

    }

this code is in the controller :

 @GetMapping(value = "score-Categorize-months")
    public List<ScoreCategorizeWithMonth> scoreCategorizedWithMonths()
    {
        return   iScoresSrv.scoreCategorizeWithMonths(userInfo.getUserId());
    }

my question is :

2- my response is the months that exist in database.how to show months even its not in the database

 {
    "scores": 27,
    "month": 1,
    "monthfa": "فروردین"
  },
  {
    "scores": 17,
    "month": 2,
    "monthfa": "اردیبهشت"
  },
  {
    "scores": 84,
    "month": 3,
    "monthfa": "خرداد"
  },
  {
    "scores": 55,
    "month": 6,
    "monthfa": "شهریور"
  } 

I want to show also the months of 4..5 with score=0

Answer 1

I just add sume code in java to fill the indexes that are invalid . it was so easy to solve . but I was a bit confused and none of the answers didnt help me

 public List<ScoreCategorizedWithMonth> scoreCategorizeWithMonths(Long userId) {
        List<ScoreCategorizedWithMonth> monthCategory = scoreDao.scoreCategorizeWithMonths(userId);
        List<ScoreCategorizedWithMonth> result = new ArrayList<>();
        for (int i=1; i<=12;i++)
        {
            ScoreCategorizedWithMonth scoreCategorizedWithMonth = checkMonthCatIsExist(i, monthCategory);
            result.add(scoreCategorizedWithMonth);
        }
        return result;
    }

    private ScoreCategorizedWithMonth checkMonthCatIsExist(int month, List<ScoreCategorizedWithMonth> monthCategory) {
        for (ScoreCategorizedWithMonth cat:monthCategory) {
            if(cat.getMonth() == month){
                return cat;
            }
        }
        ScoreCategorizedWithMonth temp= new  ScoreCategorizedWithMonth();
        temp.setMonth(month);
        temp.setScores(0);
        return temp;
    }
