- 老师 请问是参照这种写法DECLARE @json NVARCHAR(MAX);
SET @json = N'[
{"id": 2, "info": {"name": "John", "surname": "Smith"}, "age": 25},
{"id": 5, "info": {"name": "Jane", "surname": "Smith"}, "dob": "2005-11-04T12:00:00"}
]';
SELECT *
FROM OPENJSON(@json) WITH (
id INT 'strict $.id',
firstName NVARCHAR(50) '$.info.name',
lastName NVARCHAR(50) '$.info.surname',
age INT,
dateOfBirth DATETIME2 '$.dob'
); 还是 这种写法呀DECLARE @json NVARCHAR(MAX);
SET @json = N'[
{"id": 2, "info": {"name": "John", "surname": "Smith"}, "age": 25},
{"id": 5, "info": {"name": "Jane", "surname": "Smith", "skills": ["SQL", "C#", "Azure"]}, "dob": "2005-11-04T12:00:00"}
]';
SELECT id,
firstName,
lastName,
age,
dateOfBirth,
skill
FROM OPENJSON(@json) WITH (
id INT 'strict $.id',
firstName NVARCHAR(50) '$.info.name',
lastName NVARCHAR(50) '$.info.surname',
age INT,
dateOfBirth DATETIME2 '$.dob',
skills NVARCHAR(MAX) '$.info.skills' AS JSON
)
OUTER APPLY OPENJSON(skills) WITH (skill NVARCHAR(8) '$');

- 老师 比如我们想查询SELECT
device_id AS '设备ID',
point_infos AS '水质详情'
FROM
device_detail
中的point_infos字段 需要怎么调整SQL才能实现这个JSON字段（字段类型txt）获取到对应的值呀
