Spring 数据和本地查询与类似语句

Question

I have the following repository definition:

public interface InstructionRepository extends JpaRepositoryWithSpecification<Instruction> {

    String FIND_INSTRUCTIONS_BY_TRACKING_ID_QUERY =
            "SELECT * FROM instruction i WHERE i.invoice_documents_trackings like '%:trackingId%'";

    @Query(value = FIND_INSTRUCTIONS_BY_TRACKING_ID_QUERY, nativeQuery = true)
    List<Instruction> findByFileTrackingsContaining(@Param("trackingId") String trackingId);
}

The reason why I use native query here is because invoice_documents_trackings column represents a map serialized to json string. So basically I want to find all instructions that have particular trackingId stored in the invoice_documents_trackings map.

When I execute the method I always get 0 results despite the fact that If I execute the same query manually I get expected results.

I also tried to change the query so that it looks like:

String FIND_INSTRUCTIONS_BY_TRACKING_ID_QUERY =
        "SELECT * FROM instruction i WHERE i.invoice_documents_trackings like %:trackingId%"

And this does not work either.

Would really appreciate any help, than

I think the issue is the way you're using %

String FIND_INSTRUCTIONS_BY_TRACKING_ID_QUERY =
        "SELECT * FROM instruction i WHERE i.invoice_documents_trackings like CONCAT('%', :trackingId, '%')"
