T-SQL：如何解析JSON数组并提取单个属性值？

Question

鉴于：

SELECT * FROM OPENJSON(JSON_QUERY('[{"JobId":"2838","Options":1}, {"JobId":"2839","Options":1}]'))

给我们：

key value                           type
0   {"JobId":"2838","Options":1}    5
1   {"JobId":"2839","Options":1}    5

如何更改查询以返回工作ID？

value
2838
2839

Answer 1

这应该做

SELECT JobId
FROM OPENJSON('[{"JobId":"2838","Options":1}, {"JobId":"2839","Options":1}]')
WITH (JobId INT N'$.JobId');
