criteriaquery select
The SELECT clause in a CriteriaQuery determines the attributes that will be selected in the result of a SQL query. It is used to specify which columns or attributes of the table/entities should be included in the query result.
Here is an example of how to use the SELECT clause in a CriteriaQuery:
```
CriteriaBuilder criteriaBuilder = CriteriaBuilder();
CriteriaQuery<Employee> criteriaQuery = ateQuery(Employee.class);
Root<Employee> root = criteriaQuery.from(Employee.class);
criteriaQuery.("name"), ("salary")); // Selecting the "name" and "salary" attributes
List<Object[]> results = ateQuery(criteriaQuery).getResultList();
for (Object[] result : results) {
queryselectorall用法    String name = (String) result[0];
    BigDecimal salary = (BigDecimal) result[1];
    System.out.println("Name: " + name + ", Salary: " + salary);
}
```
In the above example, we create a CriteriaQuery for the Employee entity and use the select() method to specify that we want to select the "name" and "salary" attributes. We then execute the query and retrieve the results as an array of objects. Finally, we iterate over the results and extract the selected attributes to display.
