使用python将json数据插入到数据库表中

问题描述

我试图将我的 json 文件数据插入到名为 location 的数据库表中，但无论我做什么它都不起作用，我一直在 mycursor.execute 中收到相同的错误，我是 Python 的初学者，所以我不知道很多任何帮助将不胜感激，谢谢

但是现在我不断收到此错误，因为我将 tweet_id 约束设为外键，知道如何解决吗？

无法添加或更新子行：外键约束失败 (tweets.tweet_location,CONSTRAINT tweet_location_ibfk_1 FOREIGN KEY (tweet_id) REFERENCES tweet (tweet_id))

导入MysqL.connector 导入json

mydb = MysqL.connector.connect(host='localhost',port='3306',user='root',password='nihad147',database='tweets')
mycursor = mydb.cursor()

sql_location = """insert into tweet_location (
                                         latitude,longitude,tweet_id,VALUES(%s,%s,%s)"""
myJsonFile = open('tweet.json',encoding="utf-8")
mycursor.execute("DELETE FROM tweet_location")
c = 0
for line in myJsonFile:
    c = c + 1
    print("tweet number ",c," is uploading to the server")
data = json.loads(line)

tweet = ("select * from tweet ")
mycursor.execute(tweet)

myresult = mycursor.fetchall()

row_count = len(myresult)
if row_count == 0:
    val_location = (data['location']['lat'],data['location']['lon'],data['tweet_id'])
    mycursor.execute(sql_location,val_location)

mydb.commit()

这是我不断收到的错误：

文件

            mycursor.execute(sql_location,val_location)

我的json文件数据示例：

  {
      "tweet_id": "1261276320878788609","date": "Fri May 15 12:44:42 +0000 2020","raw_text": "برنامج وطني لدعم المبدعين في مواجهة #كورونا","geo_source": "user_location","location": {

        },"response": "{'place_id': 235309103,'licence': 'Data © OpenStreetMap contributors,ODbL 1.0. https://osm.org/copyright','osm_type': 'relation','osm_id': 7124228,'boundingBox': ['37.105957','37.2033466','9.4739053','9.6124953'],'lat': '37.1551868','lon': '9.54834183807249','display_name': 'العرب,غزالة,Bizerte,Tunisia','class': 'boundary','type': 'administrative','importance': 0.45,'icon': '/data/nominatimimages/mapicons/poi_boundary_administrative.p.20.png','address':{'county': 'العرب','state_district': 'غزالة','state': 'Bizerte','country': 'Tunisia','country_code': 'tn'}}","geohash": "snwg37buskzd","query_term": "arab","lon": 9.54834183807249,"lat": 37.1551868

    }

我将我的数据库表声明为 tweet_id bigint / 纬度浮点数 / 经度浮点数

解决方法

日志消息指向 insert 语句中的语法错误。列列表应放在一对括号内。你需要更换

tweet_id,

与

tweet_id)

connect connect database database database mysql python
