如何在 JSON 数组中找到等于某个值的记录

Question

我有以下 Table mytable

id   |      Json        
1    | {"test":[], "partList":[{"partid": 44, "partNum": "1234"}, {"partid": 34, "partNum": "2423"}]}
2    | {"test":[], "partList":[{"partid": 23, "partNum": "8343"}, {"partid": 34, "partNum": "2423"}]}

我正在尝试查询 where id = 2 and partNum = 2423

这是我到目前为止写的：

select *
from mytable
where id = 2
and '2423' IN (select value from OPENJSON(JSON_QUERY(Json, '$.partList'), '$.part'))

最有效的查询方式是什么？

Answer 1

这是对我有用的方法。

select *
from mytable
CROSS apply OPENJSON(Json, '$.partList') WITH ( partnumber nvarchar(100) '$.partNum' )
where partnumber = '2423'
and id = 2
