使用连接器时MySQL连接器语法错误python

问题描述

因此，我使用MysqL来存储数据，从而在python中制作了密码管理器。当我尝试使用MysqL连接器创建表时，出现以下错误：

您的sql语法有误；检查与您的MysqL服务器版本相对应的手册以获取正确的语法，以在第1行的''附近使用

我的完整代码是

import MysqL.connector as MysqL
import tkinter as tk

from simplecrypt import *

def createusr():
    global oo
    global pss
    top1 = tk.Toplevel(root)
    top1.title('Create new user ')
    top1.geometry('480x360')
    oo = tk.StringVar()
    pss = tk.StringVar()
    userid = tk.Label(top1,text = 'Enter User ID: ')
    userid.place(relx = 0.09,rely = 0.1,relheight = 0.058,relwidth = 0.24)
    entrusr = tk.Entry(top1,bg = 'gray',textvariable = id)
    entrusr.place(relx = 0.3,relwidth = 0.24)

    pwde.place(relx = 0.3,relwidth = 0.24)

    url = tk.Intvar()

def newacc():
    check = str("DROP TABLE IF EXISTS" + str(oo.get()))
    table = "CREATE TABLE {0}(SERVICE VARCHAR(100),USERNAME VARCHAR(100),PASSWORD VARCHAR(256))".format(str(oo.get()))
    cursor.execute(table)
    msql.close()




root = tk.Tk()
root.title('Cipher')

canvas.pack()

sett.place(relx = 0.9,relheight = 0.05,relwidth = 0.05)
login = tk.Button(root,text = 'Log in',font = 50)
login.place(relx = 0.2,rely = 0.7,relwidth = 0.48)

root.mainloop()

问题所在：

    def newacc():
        check = str("DROP TABLE IF EXISTS" + str(oo.get()))
        table = "CREATE TABLE {0}(SERVICE VARCHAR(100),PASSWORD VARCHAR(256))".format(str(oo.get()))
        cursor.execute(table)
        msql.close()

'''

能帮忙吗

解决方法

check = str("DROP TABLE IF EXISTS" + str(oo.get())) EXISTS关键字后必须有一个空格。

,

这里是我对发生问题的猜测

def newacc():
    check = "DROP TABLE IF EXISTS {}".format(oo.get()) 
    table = '''CREATE TABLE `{}`(
        `SERVICE` VARCHAR(100),`USERNAME` VARCHAR(100),`PASSWORD` VARCHAR(256))'''.format(oo.get())
    cursor.execute(table)
    msql.close()

请尝试一下，让我知道是否有错误。
