Python, преобразующий JSON в операторы SQL Insert

0 голосов
/ 05 ноября 2019

Я создал фрагмент Python, который выводит файл JSON, который подбирается и вставляется в наши таблицы, но я подумал, что могу ускорить процесс, просто не создавая файл JSON и создав вместо него файл операторов SQL INSERT.

Это действующая версия, которая выбирает файл: 

import os
import json
Basenames = 'C:\\Users\\Desktop\\JSON\\05174546.json'

with open(Basenames,'x') as outfile: #Creates the Json file
            json.dump(x.to_table(), outfile)

with open (Basenames,'r') as f: #Opens the Json file
jsondata = json.loads(f.read())
f.close()

for json in jsondata: #Loops through the Json file
    keylist = "("
    valuelist = "("
    firstPair = True
    for key, value in json.items():
        if not firstPair:
            keylist += ", "
            valuelist += ", "
        firstPair = False
        keylist += key
        if type(value) in (str, "utf-8"):
            valuelist += "'" + value + "'"
        else:
            valuelist += str(value)
    keylist += ")"
    valuelist += ")"

    sqlstatement += "INSERT INTO " + TABLE_NAME + " " + keylist + " VALUES " + valuelist + "\n"

print(sqlstatement)

Что бы я хотел сделать вместо этого, я просто хочу установить json.dump (x.to_table ()) равнымоднако массив, через который может пройти следующий бит, когда я попробовал это, я получаю ошибку:

AttributeError: у объекта 'str' нет атрибута 'items'
