Mysql内储存JSON字符串,根据条件进行查询(包含多层级复杂JSON查询)

1.模糊查询json类型字段
存储的数据格式(字段名 people_json):

{“name”: “zhangsan”, “age”: “13”, “gender”: “男”}

代码如下(示例):

select * from table_name where people_json->'$.name' like '%zhang%'

2.精确查询json类型字段
存储的数据格式(字段名 people_json):

{“name”: “zhangsan”, “age”: “13”, “gender”: “男”}

代码如下(示例):

select * from table_name where people_json-> '$.age' = 13

3.模糊查询JsonArray类型字段
存储的数据格式(字段名 people_json):

[{“name”: “zhangsan”, “age”: “13”, “gender”: “男”}]

代码如下(示例):

select * from table_name where people_json->'$[*].name' like '%zhang%'

4.精确查询JsonArray类型字段
存储的数据格式(字段名 people_json):

[{“name”: “zhangsan”, “age”: “13”, “gender”: “男”}]

代码如下(示例):

select * from table_name where JSON_CONTAINS(people_json,JSON_OBJECT('age', "13"))

5多层级关系,模糊查询所有的

存储的数据格式(字段名 people_json):

[{“a”: “zhangsan”, “b”: “13”, “person”: {“name”: “zhangsan”, “age”: “13”, “gender”: “男”}]}]

select * from table_name where people_json->'$**.name' like '%zhang%'

或者

多层级关系,精确匹配 查询

select * from oamm_receive_message  where JSON_SEARCH(people_json, 'all', 'zhang',NULL, '$**.name')  !=''
