MySQL Python을 사용하여 MySQL에 JSON 삽입

Python에 JSON 개체가 있습니다. Python DB-API와 SimpleJson을 사용하고 있습니다. MySQL 테이블에 json을 삽입하려고합니다.

현재 오류가 발생하고 있으며 JSON 개체의 작은 따옴표 ''때문이라고 생각합니다.

Python을 사용하여 JSON 개체를 MySQL에 삽입하려면 어떻게해야합니까?

내가 얻는 오류 메시지는 다음과 같습니다.

해결 방법

 

json.dumps (json_value)를 사용하여 json 객체 (python 객체)를 mysql의 텍스트 필드에 삽입 할 수있는 json 문자열로 변환합니다.
