[java] %Like% Query in spring JpaRepository

I would like to write a like query in JpaRepository but it is not returning anything :

LIKE '%place%'-its not working.

LIKE 'place' works perfectly.

Here is my code :

@Repository("registerUserRepository")
public interface RegisterUserRepository extendsJpaRepository<Registration,Long> {

    @Query("Select c from Registration c where c.place like :place")
     List<Registration> findByPlaceContaining(@Param("place")String place);
}

answer exactly will be

-->` @Query("select u from Category u where u.categoryName like %:input%")
     List findAllByInput(@Param("input") String input);

You dont actually need the @Query annotation at all.

You can just use the following

    @Repository("registerUserRepository")
    public interface RegisterUserRepository extends JpaRepository<Registration,Long>{
    
    List<Registration> findByPlaceIgnoreCaseContaining(String place);

    }

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

Containing: select ... like %:place%

List<Registration> findByPlaceContainingIgnoreCase(String place);

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

Using @Query in JPQL :

@Query("Select registration from Registration registration where 
registration.place LIKE  %?1%")
List<Registration> findByPlaceContainingIgnoreCase(String place);

Here are some related methods:

1. Like findByPlaceLike

   … where x.place like ?1

2. StartingWith findByPlaceStartingWith

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

3. EndingWith findByPlaceEndingWith

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

4. Containing findByPlaceContaining

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

Hope this will help you :)

I use this:

@Query("Select c from Registration c where lower(c.place) like lower(concat('%', concat(:place, '%')))")

lower() is like toLowerCase in String, so the result isn't case sensitive.

You can have one alternative of using placeholders as:

@Query("Select c from Registration c where c.place LIKE  %?1%")
List<Registration> findPlaceContainingKeywordAnywhere(String place);

when call funtion, I use: findByPlaceContaining("%" + place);

or: findByPlaceContaining(place + "%");

or: findByPlaceContaining("%" + place + "%");

Found solution without @Query (actually I tried which one which is "accepted". However, it didn't work).

Have to return Page<Entity> instead of List<Entity>:

public interface EmployeeRepository 
                          extends PagingAndSortingRepository<Employee, Integer> {
    Page<Employee> findAllByNameIgnoreCaseStartsWith(String name, Pageable pageable);
}

IgnoreCase part was critical for achieving this!

Try this.

@Query("Select c from Registration c where c.place like '%'||:place||'%'")

You can also implement the like queries using Spring Data JPA supported keyword "Containing".

List<Registration> findByPlaceContaining(String place);
