Answer 1

查询嵌套数组数据时需要使用join，请尝试以下sql：

SELECT distinct c.data  from c
join elem1 in c.data[0].Elements
join elem2 in c.data[1].Elements
where elem1.ID in(3,5,6,11) and elem2.ID in (486,492)

Answer 2

SQL

select value array(select value z.ID from z in a.Elements)
from c
join b in c.data
join a in b

结果

    [
        11,
        16,
        3,
        5
    ],
    [
        486,
        492
    ]
