SQLSyntaxErrorException and How to call a Get method with 2 parameters?

Question

* note1: What is wrong with my query? it's exactly the same code as MySQL

* note2: Is wrong to call my get method like these with the 2 parameters I have?

Is there any better way or documentation to help me with this current error ?

Maybe is it better to make a projection or what? Please give me some help I'm new to spring and so lost, sorry for that extra info!

Mysql:

SELECT id_product,date,
sum(case  
 when  action_description = "import" 
  then quantity_product
  else -quantity_product
END) as test
 FROM testdb.warehouse_management
inner join product
on warehouse_management.product_id = product.id_product
where id_product = 1 and date <= 1200
group by id_product,date

Repository:

@Repository
public interface ManagementRepository extends JpaRepository<Management,Long>,ManagementRepositoryCustom{

    @Query(value = "SELECT id_product,date " +
            "sum(case " + // add space for all these lines
            "when action_description = 'import' " +
            "then quantity_product " +
            "else -quantity_product " +
            "END)  as test " +
            "FROM warehouse_management " +
            "inner join product " +
            "on warehouse_management.product_id = product.id_product " +
            "where id_product =:id_product and date <=:date " +
            "group by id_product,date ",nativeQuery = true)
    List<StockRecoveryDTO> findSum(@Param("id_product") Long id_product, @Param("date") String date) ;
}

Rest Controller:

@GetMapping(path = "{id_product}/{date}")
public List<StockRecoveryDTO> findSum(@Param("id_product") String id_product, @Param("date") String date) {
    return this.managementService.findSum(id_product,date);
}

DTO:

public class StockRecoveryDTO {

    private Long id_product;
    private String date;
    private int quantity_product;
    private String action_description;
    private Long id_action;
    private String quantity;


    public StockRecoveryDTO() {

    }

//Getter & Setter

Answer 1

Please follow the tutorial bellow and if you still can't find it repost your problem with better syntax :

Answer 2

您缺少一个逗号：“SELECT id_product,date” + “sum(case” --- date 和 sum 之间需要有一个逗号，这就是为什么错误消息指向 sum( 并说“错误是这里”。---投票结束问题为“错字”。 – 安德烈亚斯
