CosmosDB SQL查询匹配数组中的多个值

Question

我正在使用Cosmos DB,我想编写一个匹配数组中多个值的SQL查询.要详细说明,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"
            }
        ]
    }
]

我想写一个查询,它将返回所有占用job_title为"Billionaire"和"Batman"的条目.要清楚结果必须有两个job_titles.因此,在上面的集合中,它应该只返回B​​ruce Wayne.

到目前为止,我尝试过:

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' })

和

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.

你需要使用ARRAY_CONTAINS(array,search_value,is_partial_match = true),即查询是:

SELECT c.id, c.name, c.occupations 
FROM c
WHERE ARRAY_CONTAINS(c.occupations, {'job_title': 'Billionaire' }, true)
AND ARRAY_CONTAINS(c.occupations, {'job_title': 'Batman' }, true)
