Check if an integer is in a jsonb list

Question

I'm trying to write a native query in JPA. I want to verify if an element exists in a jsonb column. However, I'm getting the error integer <@ jsonb .

This is my query:

@Query(
        value = "SELECT u FROM user u WHERE (u.depNum = ?1 and superAdmin = true " +
            "       and ?2 <@ (u.listUsers)) ",
        nativeQuery = true

    )
    public List<EbUser> selectSuperAdmin(Integer depNum, Integer userNum);

The error happens here: ?2 <@ (u.listUsers) . How can I verify that listUsers contains the userNum or how can I convert the userNum to jsonb in Java?

Answer 1

You can do the conversion in PostgreSQL.

and to_jsonb(ARRAY[?2]) <@ (u.listUsers))

as long as JPA doesn't interfere with passing this construct into PostgreSQL, I have not tested that part.
