Hi I have the following code:
Controller:
@GetMapping("/salesTrend")
private List<Object[]> salesTrend(){
int[] profit = {1,2,3,4,5,6,7,8,9,10,11,12};
return customerRepository.findByProfit(profit);
}
Repository:
@Query(
value = "SELECT MONTH(f_date), SUM(profit) as p from finance where MONTH(f_date) = ?1",
nativeQuery = true)
List<Object[]> findByProfit(int[] profit);
the result of this is null and I am struggling to know why that is because I tested this already on xampp and it works fine I don't know what I'm doing wrong thank you
I have solved it already thanks to the comment of @ppeterka I just made an array containing all the months then I looped each of the elements in the array to put them at the query one at a time like so
int[] profit = {1,2,3,4,5,6,7,8,9,10,11,12,13};
List<Object> profitList = new ArrayList<>();
for(int i = 1; i < profit.length; i++) {
List<Object[]> results = customerRepository.findByProfit(i);
for(Object[] obj : results) {
Map<Object, Object> profits = new LinkedHashMap<>();
profits.put("Month", obj[0]);
profits.put("Profit", obj[1]);
profitList.add(profits);
}
}
