如何在带有 Spring Boot 的本机查询中使用 all(array[])？

Question

I've tried to do a native query with Spring Boot using all(array[]) function, however, I couldn't make it correctly. I don't know the quantity of Strings that I'll pass, it's a dynamic quantity. Can you guys help me on this, please?

I've tried using List<String> , String[] and just String as below:

1. passing String and in the query all(array[:texto]) : no errors, however, no results.

2. passing List<String> and in the query all(array[:texto]) :

org.postgresql.util.PSQLException: ERROR: operator does not exist: character varying ~~* record
  Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.

3. passing String[] and in the query all(array[:texto]) :

org.postgresql.util.PSQLException: ERROR: operator does not exist: character varying ~~* bytea
  Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.

4. passing String[] and in the query all(array[CAST(:texto AS TEXT)]) : no errors, however, no results.

@Query(value="SELECT * FROM Tag WHERE nome ILIKE all(array[:texto])", nativeQuery=true)
public List<Tag> findPacotesByTexto(@Param("texto") List<String> texto);

EDITED:

@Entity
public class Tag {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column(nullable = false)
    private String nome;

    @ManyToOne
    @JsonIgnore
    @JoinColumn(name="pacote_id")
    private Pacote pacote;

    Tag() {

    }

    public Tag (String nome, Pacote pacote) {
        this.nome = nome;
        this.pacote = pacote;
    }

    public long getId() {
        return id;
    }

    public String getNome() {
        return nome;
    }

    public Pacote getPacote() {
        return pacote;
    }

}

How can I make this work?

Thanks in advance.

Answer 1

In a native query approach, the SQL is passed exactly to be executed as is what it's written. And I think the framework could not serialize your collection as the required pattern all(array[?, ?, ?, ...]) . In that case, you should convert your parameter before passing to the method or change the approach to not using the native query.

Had the same trouble casting the list to a text[] using spring + hibernate & native query

See https://stackoverflow.com/a/55179555/335264 for a working solution (uses two postgresql functions to do the casting)
