我正在使用 Cosmos DB,我想编写一个 SQL 查询来匹配数组中的多个值。为了详细说明,假设您有以下集合:
[
{
"id": "31d4c08b-ee59-4ede-b801-3cacaea38808",
"name": "Oliver Queen",
"occupations": [
{
"job_title": "Billionaire",
"job_satisfaction": "pretty good"
},
{
"job_title": "Green Arrow",
"job_satisfaction": "meh"
}
]
},
{
"id": "689bdc38-9849-4a11-b856-53f8628b76c9",
"name": "Bruce Wayne",
"occupations": [
{
"job_title": "Billionaire",
"job_satisfaction": "pretty good"
},
{
"job_title": "Batman",
"job_satisfaction": "I'm Batman"
}
]
},
{
"id": "d1d3609a-0067-47e4-b7ff-afc7ee1a0147",
"name": "Clarke Kent",
"occupations": [
{
"job_title": "Reporter",
"job_satisfaction": "average"
},
{
"job_title": "Superman",
"job_satisfaction": "not as good as Batman"
}
]
}
]
我想编写一个查询,该查询将返回具有 job_title 为“亿万富翁”和“蝙蝠侠”的职业的所有条目。需要明确的是,结果必须同时具有两个 job_titles。所以在上面的集合中它应该只返回 Bruce Wayne。
到目前为止我已经尝试过:
SELECT c.id, c.name, c.occupations FROM c
WHERE ARRAY_CONTAINS(c.occupations, {'job_title': 'Billionaire' })
AND ARRAY_CONTAINS(c.occupations, {'job_title': 'Batman' })
and
SELECT c.id, c.name, c.occupations FROM c
WHERE c.occupations.job_title = 'Batman'
AND c.occupations.job_title = 'Billionaire'
两者都返回空结果。
