在mysql db的单个单元格中插入python字典

Question

I have this dictionary in python. I am trying to insert it in mysql db. So I convert it to json using json.dumps, still I get the error that not all arguments converted during string formatting. What should be done?

{'point': '+', 'time': '00:02', 'acceptedSubmissionId': 42, 'title': 'GNU C++'}

My code: cursor.execute("insert into tablename A value %s", json.dumps(user['scoreCard'][i]))

EDIT : I put the json in square brackets, to make a tuple, and it works. Is this correct?? cursor.execute("insert into contest_"+str(id)+" ("+str(unichr(i + 65))+") values (%s)", [json.dumps(user['scoreCard'][i])])

Answer 1

Use this instead:

cursor.execute("insert into tablename A value {0}", json.dumps(user['scoreCard'][i]))

The notation %s will be deprecated soon.
