Spring JPA @Query with LIKE

I'm trying to make a method in CrudRepository that will be able to give me list of users, whose usernames are LIKE the input parameter(not only begin with, but also contains it). I tried to use method "findUserByUsernameLike(@Param("username") String username)" but as it is told in Spring documentation, this method is equal to "where user.username like ?1". It is not good for me, as I already told that I'm trying to get all users whose username contains ...

I wrote a queryto the method but it even doesn't deploy.

@Repository
public interface UserRepository extends CrudRepository<User, Long> {

@Query("select u from user u where u.username like '%username%'")
List<User> findUserByUsernameLike(@Param("username") String username);
}

Can anybody help me with this?

Try to use the following approach (it works for me):

@Query("SELECT u.username FROM User u WHERE u.username LIKE CONCAT('%',:username,'%')")
List<String> findUsersWithPartOfName(@Param("username") String username);

Notice: The table name in JPQL must start with a capital letter.

> Using Query creation from method names, check table 4 where they explain some keywords.

1. Using Like: select ... like :username

    List<User> findByUsernameLike(String username);
   

2. StartingWith: select ... like :username%

    List<User> findByUsernameStartingWith(String username);
   

3. EndingWith: select ... like %:username

    List<User> findByUsernameEndingWith(String username);
   

4. Containing: select ... like %:username%

    List<User> findByUsernameContaining(String username);
   

Notice that the answer that you are looking for is number 4. You don't have to use @Query

Another way: instead CONCAT function we can use double pipe: :lastname || '%'

@Query("select c from Customer c where c.lastName LIKE :lastname||'%'")
List<Customer> findCustomByLastName( @Param("lastname") String lastName);

You can put anywhere, prefix, suffix or both

:lastname ||'%'  
'%' || :lastname  
'%' || :lastname || '%'  

Easy to use following (no need use CONCAT or ||):

@Query("from Service s where s.category.typeAsString like :parent%")
List<Service> findAll(@Param("parent") String parent);

Documented in: http://docs.spring.io/spring-data/jpa/docs/current/reference/html.

List<User> findByUsernameContainingIgnoreCase(String username);

in order to ignore case issues

For your case, you can directly use JPA methods. That is like bellow:

Containing: select ... like %:username%

List<User> findByUsernameContainingIgnoreCase(String username);

here, IgnoreCase will help you to search item with ignoring the case.

Here are some related methods:

1. Like findByFirstnameLike

   … where x.firstname like ?1

2. StartingWith findByFirstnameStartingWith

   … where x.firstname like ?1 (parameter bound with appended %)

3. EndingWith findByFirstnameEndingWith

   … where x.firstname like ?1 (parameter bound with prepended %)

4. Containing findByFirstnameContaining

   … where x.firstname like ?1 (parameter bound wrapped in %)

Hope this will help you :)

This way works for me, (using Spring Boot version 2.0.1. RELEASE):

@Query("SELECT u.username FROM User u WHERE u.username LIKE %?1%")
List<String> findUsersWithPartOfName(@Param("username") String username);

Explaining: The ?1, ?2, ?3 etc. are place holders the first, second, third parameters, etc. In this case is enough to have the parameter is surrounded by % as if it was a standard SQL query but without the single quotes.

You Missed a colon(:) before the username parameter. therefore your code must change from:

@Query("select u from user u where u.username like '%username%'")

to :

@Query("select u from user u where u.username like '%:username%'")

this @Query("select u from user u where u.username like '%:username%'") does not work in some cases!

working solution for me was

@Query("SELECT u.username FROM User u WHERE u.username LIKE CONCAT('%',:username,'%')")

@Query("select u from user u where u.username LIKE :username")
List<User> findUserByUsernameLike(@Param("username") String username);

@Query("select b.equipSealRegisterId from EquipSealRegister b where b.sealName like %?1% and b.deleteFlag = '0'" )
	List<String>findBySeal(String sealname);

I have tried this code and it works.
