数据库上变量的语法错误(MySQL/Python)
起初我声明了一个变量nom_of_game_db,但之后我在MySQL级别找不到正确的语法来回调该变量:数据库上变量的语法错误(MySQL/Python),python,mysql,database,scrapy,Python,Mysql,Database,Scrapy,起初我声明了一个变量nom_of_game_db,但之后我在MySQL级别找不到正确的语法来回调该变量: # -*- coding: utf-8 -*- name_of_game_db = input("Name of game ?") class QuotetutorialPipeline(object): def __init__(self): self.create_connection() self.create_table()
# -*- 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()
在执行execute to create table语句之后,我使用Python和MySQL使用self.conn.commit提交db更改,并重命名drop table exist sql命令。显示错误。我只想找到好的语法来调用变量的值将变量定义为全局变量
