Question

在下面的DocumentDB文档中，查询DevicePin的正确方法是什么？即WHERE DevicePin =＆＃39; 1234＆＃39; 我使用Node.js并使基本查询正常工作，我可以查询电子邮件和名称之类的内容，只是无法获得DevicePin的语法正确

}

Answer 1

知道了，以防其他人想要这样做：

SELECT * 
FROM c.DeviceIDs[0] d 
WHERE (d.DevicePin = "1234")

Answer 2

如果您不知道数组元素编号，则可以使用

 SELECT * FROM c WHERE 
    array_contains(c.DeviceIDs, {"DevicePin": "1234"})

DocumentDB查询文档中的子元素
