IllegalArgumentException: Вы попытались установить значение типа java.lang.String для параметра разметки с ожидаемым типом java.math.BigDecimal

Question

Когда я исполняю ниже запрос,

public int checkIfQueryExist(String query){ 
    List<Product> products= em.createQuery("SELECT p FROM Product p WHERE p.markup=:markup"). 
      setParameter("markup", query).getResultList(); 
    return products.size(); 
} 

я получаю ниже исключение :

Caused by: java.lang.IllegalArgumentException: You have attempted to set a value of type class java.lang.String for parameter markup with expected type of class java.math.BigDecimal from query string SELECT p FROM Product p WHERE p.markup=:markup.

Проблема скрывается прямо в трассировки стека

Caused by: java.lang.IllegalArgumentException: You have attempted to set a value of type class java.lang.String for parameter markup with expected type of class java.math.BigDecimal from query string SELECT p FROM Product p WHERE p.markup=:markup.

Просто попробуйте преобразовать query ввести BigDecimal в методе checkIfQueryExist
