SQL 服务器 where JSON 字段上的子句

Question

我有一个table

ID |  Start Date       | End Date          | Summary
---+-------------------+-------------------+----------------------------
1  | 2020-01-01T09:20  | 2020-01-01T09:30  | {"total":20,"totalError":10}
1  | 2020-01-02T09:20  | 2020-01-02T10:55  | {"total":10,"totalError":5}

我要查询where totalError > 0

Select * 
from runLog 
where Summary.totalError > 0

这可能吗？

Answer 1

使用JSON_VALUE():

select * from runLog where json_value(summary, '$.totalError') > 0
