首先,我声明了一个变量“ nom_of_game_db”,但是此后,我在MySQL级别上找不到正确的语法来将该变量回叫:
# -*- coding: utf-8 -*-
name_of_game_db = input("Name of game ?")
class QuotetutorialPipeline(object):
def __init__(self):
self.create_connection()
self.create_table()
def create_connection(self):
self.conn = mysql.connector.connect(
host = 'localhost',
user = 'root',
passwd = 'jozefleonel',
database = 'prices'
)
self.curr = self.conn.cursor()
def create_table(self):
self.curr.execute("""DROP TABLE IF EXISTS nam_of_game_db""")
self.curr.execute("""create table name_of_game_db(
name text,
platform text,
edition text
)""")
def process_item(self, item, spider):
self.store_db(item)
return item
def store_db(self,item):
self.curr.execute("""insert into name_of_game_db values (%s,%s,%s)""", (
item['name'][0],
item['platform'][0],
item['edition'][0]
))
self.conn.commit()
我使用Python和MySQL
答案 0 :(得分:1)
执行完表创建语句后,使用self.conn.commit()提交数据库更改,并重命名drop table exist sql命令。
