#Query keep pulling null from database - mysql

Question

I am currently having what I'd like to call as Code Block (Writer block but with coding). I have tried to check many times and make sure that everything is in the proper place but it keeps getting me a null despite the data that I ask in the #Query is exist.
This is the #Query that I currently have,
#Query(value = "select d.denda from data_transaksi_model d WHERE d.tanggal=:x AND d.nama_wp = :y AND d.masa_pajak=:z", nativeQuery = true)
String findAllDenda(String x,String y,String z);
My expected output from there is a collection of "denda" from the table of "data_transaksi_model" which has the specific "tanggal", "name", and "masa_pajak" from that table. I have double checked the table that is created within the database and it has the same name as to what I inquire there,
As you can see, the table name is matchup and the name of the column name that has the name of what I want in my query is also match up. Just to make sure, I also check the structure of the database and it is indeed a string, also the same with others.
The table is the byproduct of the model from my Spring Boot's project that I have made.

With that finished, I insert a data dummy into the database as the following.
Therefore, I tried to put the input of tanggal with "1170130", nama_wp with "SURATNO" and masa_pajak with "2016". However, I keep getting null instead of "9.166" in the collection. Where did I do wrong? I am using XAMPP, MySQL, and Spring Boot for this project.
/EDIT: I tried it manually in my XAMPP with SELECT denda FROM data_transaksi_modelWHERE nama_wp="SURATNO" AND masa_pajak="2014" AND tanggal="1170130" and it actually gives me a return
However, when I do it in my spring boot project it still return null.
//Edit2: I am using IntelliJ as my IDE and there is a warning (not an error) within the #Query annotation. It is said that "No data sources are configured to run this SQL and provide advanced code assistance. Disable this inspection via problem menu (alt+enter)" there is also a warning that said, "SQL dialect is not configured". If that is the source of the problem, how to fix it?
///edit3: I tried to fix around the query and it doesn't show the result that I wanted. This is the service that I am using for the repository
#Autowired
DataTransaksiDb dataTransaksiDb;
#Override
public List<String> getDenda(String tanggal, String nama, String masaPajak){
// TODO Auto-generated method stub
return dataTransaksiDb.findAllDenda(tanggal, nama, masaPajak);
}
and this is the controller where I am using the service. The controller is using a multipart file where the data is taken out from the CSV that is uploaded where within the CSV has the table that is the same as the database.
#PostMapping("/uploadFile")
public static void uploadFile(#RequestParam("file") MultipartFile file, HttpServletResponse response) throws IOException {
if (file.getContentType().equalsIgnoreCase("application/vnd.ms-excel")) {
InputStreamReader input = new InputStreamReader(file.getInputStream());
CSVParser csvParser = CSVFormat.EXCEL.withFirstRecordAsHeader().parse(input);
for (CSVRecord record : csvParser) {
String nama = record.get("nama_wp");
String masa = record.get("masa_pajak");
String tanggal = record.get("tanggal");
String denda = record.get("denda");
String jumlahSetoran = record.get("jumlah_setoran");
String pokok = record.get("pokok");
String luasTanah = record.get("luas_tanah");
String luasBangunan = record.get("luas_bangunan");
try {
System.err.println(tanggal + "\n" + nama + "\n" + masa);
List<String> results = rekonsiliasiService.getDenda(tanggal, nama, masa);
System.err.println("results " + results);
} catch (NullPointerException e) {
System.err.println(e);
}
}
response.sendRedirect("/rekonsiliasi");
} else {
response.sendRedirect("/rekonsiliasi");
}
}
Whatever the result of the input that I get, it keep getting catches by the nullpointerexception
////EDIT4:
I tried debugging it and from my controller, I tried to do System.err.println(rekonsiliasiService.getDenda(tanggal,nama,masa)); and it keep me getting a NullPointerException. Then I tried to see if the problem is the input of the parameter itself within the service
#Override
public List<String> getDenda(String tanggal, String nama, String masaPajak){
// TODO Auto-generated method stub
System.err.println("tanggal " + tanggal + "\n" + "nama " + nama + "\n" + "masaPajak " + masaPajak);
return dataTransaksiDb.findAllDenda(tanggal, nama, masaPajak);
}
It never reached to the System.err.println("tanggal " + tanggal + "\n" + "nama " + nama + "\n" + "masaPajak " + masaPajak); within my Service layer.

try this :
#Query(value = "select d.denda from DataTransaksiModel d WHERE d.tanggal=:x AND d.namaWP = :y AND d.masaPajak=:z")
List<String> findAllDenda(#Param("x")String x, #Param("y")String y,#Param("z") String z);
if it didn't work try this :
#Query(value = "select d.denda from data_transaksi_model d WHERE d.tanggal=:x AND d.nama_wp = :y AND d.masa_pajak=:z", nativeQuery = true)
List<String> findAllDenda(#Param("x")String x, #Param("y")String y,#Param("z") String z);
