ANY/ALL（数组）不支持设置参数

Question

我有一个 jsonb 列，其中包含有关促销活动的详细信息。

我想过滤预定义列表中的键。

我应用了对我来说很直观的东西，一个 where code in ('foo', 'bar') 但这引发了一个错误：ANY/ALL (array) does not support set arguments

有什么想法吗？

查询：

select
    upper(jsonb_object_keys(orders.extra_details -> 'promotion_codes')) as promo_code,
    count(tickets.id)
from 
    tickets
    inner join order_items on order_items.orderable_id = tickets.id
    inner join orders on orders.id = order_items.order_id
where 
    order_items.type = 'TicketOrderItem'
    and orders.extra_details -> 'promotion_codes' is not null
    and tickets.event_id = 4062
    and tickets.status = 2
    and upper(jsonb_object_keys(orders.extra_details -> 'promotion_codes')) in ('FOO', 'BAR', 'BAZ')
group by 
    1
order by 
    1

Answer 1

jsonb_object_keys returns 一组值。你不应该在 select 列表中使用它，你不能真正在 where 子句中使用它。

就像使用这样的表达式：where (select some_column from some_table) in ('a','b')

正确的使用方法是将查询加入 jsonb_object_keys

的结果

select upper(ed.promo_code) as promo_code,
       count(tickets.id)
from tickets
  join order_items on order_items.orderable_id = tickets.id
  join orders on orders.id = order_items.order_id
  join lateral jsonb_object_keys(orders.extra_details -> 'promotion_codes') as ed(promo_code) on true
where 
    order_items.type = 'TicketOrderItem'
    and orders.extra_details -> 'promotion_codes' is not null
    and tickets.event_id = 4062
    and tickets.status = 2
    and upper(ed.promo_code) in ('FOO', 'BAR', 'BAZ')
group by 
    1
order by 
    1
