1. Overview

Spring Data provides many ways to define a query that we can execute. One of these is the @Query annotation.

In this tutorial, we’ll demonstrate how to use the @Query annotation in Spring Data JPA to execute both JPQL and native SQL queries.

Also, we’ll show how to build a dynamic query when the @Query annotation is not enough.

2. Select Query

In order to define SQL to execute for a Spring Data repository method, we can annotate the method with the @Query annotation — its value attribute contains the JPQL or SQL to execute.

The @Query annotation takes precedence over named queries, which are annotated with @NamedQuery or defined in an orm.xml file.

It’s a good approach to place a query definition just above the method inside the repository rather than inside our domain model as named queries. The repository is responsible for persistence, so it’s a better place to store these definitions.

2.1. JPQL

By default the query definition uses JPQL.

Let’s look at a simple repository method that returns active User entities from the database:

@Query("SELECT u FROM User u WHERE u.status = 1")
Collection<User> findAllActiveUsers();

2.2. Native

We can use also native SQL to define our query. All we have to do is to set the value of the nativeQuery attribute to true and define the native SQL query in the value attribute of the annotation:

value = "SELECT * FROM USERS u WHERE u.status = 1",
nativeQuery = true)
Collection<User> findAllActiveUsersNative();

3. Define Order in a Query

We can pass an additional parameter of type Sort to a Spring Data method declaration that has the @Query annotation. It’ll be translated into the ORDER BY clause that gets passed to the database.

3.1. Sorting for JPA Provided and Derived Methods

For the methods we get out-of-the-box like findAll(Sort) or the ones that are generated by parsing method signatures, we can only use object properties to define our sort:

userRepository.findAll(new Sort(Sort.Direction.ASC, "name"));

Now imagine that we want to sort by the length of a name property:

userRepository.findAll(new Sort("LENGTH(name)"));

When we execute the above code we’ll receive an exception:

org.springframework.data.mapping.PropertyReferenceException: No property lENGTH(name) found for type User!

3.2. JPQL

When we use JPQL for a query definition, then Spring Data can handle sorting without any problem — all we have to do is to add a method parameter of type Sort:

@Query(value = "SELECT u FROM User u")
List<User> findAllUsers(Sort sort);

We can call this method and pass a Sort parameter, which will order the result by the name property of the User object:

userRepository.findAllUsers(new Sort("name"));

And because we used @Query annotation, we can use the same method to get the sorted list of Users by the length of their names:


It’s crucial that we use JpaSort.unsafe() to create a Sort object instance.

When we use:

new Sort("LENGTH(name)");

then we’ll receive exactly the same exception as we saw above for the findAll() method.

When Spring Data discovers the unsafe Sort order for a method that uses the @Query annotation, then it just appends the sort clause to the query — it skips checking whether the property to sort by belongs to the domain model.

3.3. Native

When the @Query annotation uses native SQL, then it’s not possible to define a Sort.

If we do, we’ll receive an exception:

org.springframework.data.jpa.repository.query.InvalidJpaQueryMethodException: Cannot use native queries with dynamic sorting and/or pagination

As the exception says, the sort isn’t supported for native queries. The error message gives us a hint that pagination will cause an exception too.

4. Pagination

Pagination allows us to return just a subset of a whole result in a Page. This is useful, for example, when navigating through several pages of data on a web page.

Another advantage of pagination is that the amount of data sent from server to client is minimized. By sending smaller pieces of data, we can generally see an improvement in performance.

4.1. JPQL

Using pagination in the JPQL query definition is straightforward:

@Query(value = "SELECT u FROM User u ORDER BY id")
Page<User> findAllUsersWithPagination(Pageable pageable);

We can pass a PageRequest parameter to get a page of data. Pagination is also supported for native queries but requires a little bit of additional work.

4.2. Native

We can enable pagination for native queries by declaring an additional attribute countQuery — this defines the SQL to execute to count the number of rows in the whole result:

value = "SELECT * FROM Users ORDER BY id",
countQuery = "SELECT count(*) FROM Users",
nativeQuery = true)
Page<User> findAllUsersWithPagination(Pageable pageable);

4.3. Spring Data JPA Versions Prior to 2.0.4

The above solution for native queries works fine for Spring Data JPA version 2.0.4 and later.

Prior to that version, when we try to execute such a query we’ll receive an exception — the same one we described in the previous section on sorting.

We can overcome this by adding an additional parameter for pagination inside our query:

value = "SELECT * FROM Users ORDER BY id \n-- #pageable\n",
countQuery = "SELECT count(*) FROM Users",
nativeQuery = true)
Page<User> findAllUsersWithPagination(Pageable pageable);

In the above example, we add “\n– #pageable\n” as the placeholder for the pagination parameter. This tells Spring Data JPA how to parse the query and inject the pageable parameter. This solution works for the H2 database.

5. Indexed Query Parameters

There are two possible ways that we can pass method parameters to our query. In this section, we’ll cover indexed parameters.

5.1. JPQL

For indexed parameters in JPQL, Spring Data will pass method parameters to the query in the same order they appear in the method declaration:

@Query("SELECT u FROM User u WHERE u.status = ?1")
User findUserByStatus(Integer status);

@Query("SELECT u FROM User u WHERE u.status = ?1 and u.name = ?2")
User findUserByStatusAndName(Integer status, String name);

For the above queries, the status method parameter will be assigned to the query parameter with index 1, and the name method parameter will be assigned to the query parameter with index 2.

5.2. Native

Indexed parameters for the native queries work exactly in the same way as for JPQL:

value = "SELECT * FROM Users u WHERE u.status = ?1",
nativeQuery = true)
User findUserByStatusNative(Integer status);

6. Named Parameters

We can also pass method parameters to the query using named parameters. We define these using the @Param annotation inside our repository method declaration.

Each parameter annotated with @Param must have a value string matching the corresponding JPQL or SQL query parameter name. A query with named parameters is easier to read and is less error-prone in case the query needs to be refactored.

6.1. JPQL

As mentioned above, we use the @Param annotation in the method declaration to match parameters defined by name in JPQL with parameters from the method declaration:

@Query("SELECT u FROM User u WHERE u.status = :status and u.name = :name")
User findUserByStatusAndNameNamedParams(
@Param("status") Integer status,
@Param("name") String name);

Note that in the above example, we defined our SQL query and method parameters to have the same names, but it’s not required, as long as the value strings are the same:

@Query("SELECT u FROM User u WHERE u.status = :status and u.name = :name")
User findUserByUserStatusAndUserName(@Param("status") Integer userStatus,
@Param("name") String userName);

6.2. Native

For the native query definition, there is no difference how we pass a parameter via the name to the query in comparison to JPQL — we use the @Param annotation:

@Query(value = "SELECT * FROM Users u WHERE u.status = :status and u.name = :name", 
nativeQuery = true)
User findUserByStatusAndNameNamedParamsNative(
@Param("status") Integer status, @Param("name") String name);

7. Collection Parameter

Let’s consider the case when the where clause of our JPQL or SQL query contains the IN (or NOT IN) keyword:

SELECT u FROM User u WHERE u.name IN :names

In this case we can define a query method which takes Collection as a parameter:

@Query(value = "SELECT u FROM User u WHERE u.name IN :names")
List<User> findUserByNameList(@Param("names") Collection<String> names);

As the parameter is a Collection it can be used with List, HashSet, etc.

8. Update Queries with @Modifying

We can use the @Query annotation to modify the state of the database by also adding the @Modifying annotation to the repository method.

8.1. JPQL

The repository method that modifies the data has two difference in comparison to the select query — it has the @Modifying annotation and, of course, the JPQL query uses update instead of select:

@Query("update User u set u.status = :status where u.name = :name")
int updateUserSetStatusForName(@Param("status") Integer status,
@Param("name") String name);

The return value defines how many rows the execution of the query updated. Both indexed and named parameters can be used inside update queries.

8.2. Native

We can modify the state of the database also with a native query — we just need to add the @Modifying annotation:

@Query(value = "update Users u set u.status = ? where u.name = ?",
nativeQuery = true)
int updateUserSetStatusForNameNative(Integer status, String name);

8.3. Inserts

To perform an insert operation, we have to both apply @Modifying and use a native query

@Query(value = "insert into Users (name, age, email, status) values (:name, :age, :email, :status)",
nativeQuery = true)
void insertUser(@Param("name") String name, @Param("age") Integer age,
@Param("status") Integer status, @Param("email") String email);

9. Dynamic Query

Often times, we’ll encounter the need for building SQL statements based on conditions or data sets whose values are only known at runtime. And, in those cases, we can’t just use a static query.

9.1. Example of a Dynamic Query

For example, let’s imagine a situation, where we need to select all the users whose email is LIKE one from a set defined at runtime — email1, email2, …, emailn:

SELECT u FROM User u WHERE u.email LIKE '%email1%'
or u.email LIKE '%email2%'
or u.email LIKE '%emailn%'

Since the set is dynamically constructed, we can’t know at compile-time how many LIKE clauses to add.

In this case, we can’t just use the @Query annotation since we can’t provide a static SQL statement.

Instead, by implementing a custom composite repository, we can extend the base JpaRepository functionality and provide our own logic for building a dynamic query.

9.2. Custom Repositories and the JPA Criteria API

Luckily for us, Spring provides a way for extending the base repository through the use of custom fragment interfaces. We can then link them together to create a composite repository.

We’ll start by creating a custom fragment interface:

public interface UserRepositoryCustom {
List<User> findUserByEmails(Set<String> emails);

And then, we’ll implement it:

public class UserRepositoryCustomImpl implements UserRepositoryCustom {

private EntityManager entityManager;

public List<User> findUserByEmails(Set<String> emails) {
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<User> query = cb.createQuery(User.class);
Root<User> user = query.from(User.class);

Path<String> emailPath = user.get("email");

List<Predicate> predicates = new ArrayList<>();
for (String email : emails) {
predicates.add(cb.like(emailPath, email));
.where(cb.or(predicates.toArray(new Predicate[predicates.size()])));

return entityManager.createQuery(query)

As shown above, we leveraged the JPA Criteria API to build our dynamic query.

Also, we need to make sure to include the Impl postfix in the class name. Spring will search the UserRepositoryCustom implementation as UserRepositoryCustomImpl. Since fragments are not repositories by themselves, Spring relies on this mechanism to find the fragment implementation.

9.3. Extending the Existing Repository

Notice that all the query methods from section 2 — section 7 are in the UserRepository. So now, we’ll integrate our fragment by extending the new interface in the UserRepository :

public interface UserRepository extends JpaRepository<User, Integer>, UserRepositoryCustom {
// query methods from section 2 - section 7

9.4. Using the Repository

And finally, we can call our dynamic query method:

Set<String> emails = new HashSet<>();
// filling the set with any number of items


We’ve successfully created a composite repository and called our custom method.
