mysql解析json下的某个字段

select * from 表名 where json字段名 ->> '$.json下的key值'

如果遇到json 嵌套的情况

select * from 表名 where json字段名 ->> '$.json下的key值.key值'以此类推。

（仅仅支持mysql5.7版本及以上）

id	message_content
1	{"reason": "未匹配任何规则", "applyId": "677ccd673a774283b10481c5c3104946", "auditConsequence": "0"}
2	{"reason": "未匹配任何规则", "applyId": "677ccd673a774283b10481c5c3104945", "auditConsequence": "0"}
3	{"reason": "未匹配任何规则", "applyId": "e39b453b9ae04e4980caba9099fbc551", "auditConsequence": "1"}

SELECT
message_content ->> '$.reason'
FROM
表名
WHERE
message_content ->> '$.auditConsequence' = '-1'
