相当于 'includes' 的运算符

Question

我正在尝试连接一堆表，我是 Postgres 和 Knex 的新手。

是否有与 javascript 运算符 'includes' 等价的运算符？例如我想做这样的事情：

JOIN tbl ON somearrayofIds 'includes' tbl.id

这是我的提取查询：

db('posts AS p')
    .select(
      'p.id as postId',
      'p.user_id as pUserId',
      'p.content',
      'p.created_at',
      'p.updated_at',
      'p.image_url as postImage',
      'pr.post_id as prPostId',
      'pr.reaction_ids as prReactionIds',
      'pr.user_ids as prUserIds',
      'r.id as rId',
      'r.keyword as rKeyword',
    )
    .leftJoin('post_reactions AS pr', 'pr.post_id', '=', 'p.id')
    .leftJoin('reactions AS r', 'r.id', 'includes', 'pr.reaction_ids') // r.id is string, pr.reaction_ids is array

Answer 1

是这样的吗？:

create table array_test(id int, array_fld int[]);
insert into array_test values (1, '{1, 3, 5}');

select * from array_test where 1 = ANY(array_fld);
 id | array_fld 
----+-----------
  1 | {1,3,5}

select * from array_test where 2 = ANY(array_fld);
 id | array_fld 
----+-----------
(0 rows)
