使用 Python 在 MYSQL 数据库中创建表错误

Question

我想为已存储在文件中的数据创建一个数据库。为此，我使用文件处理从存储的文件中读取数据并输入到我的数据库表中。但它显示下面给出的错误。

将数据存储选项从文件切换到数据库是否正确？

发生的错误如下-:

Traceback (most recent call last):

mysql.connector.errors.ProgrammingError: 1146 (42S02): Table 'pump.petrol' doesn't exist

这是从文件中读取数据然后输入数据库的代码。

import pickle
def indatabase() :
    # FOR PETROL
    import mysql.connector


    try :
        conn = mysql.connector.connect (host='localhost' ,database='PUMP' ,user='asdad' ,
        password='11234567')

        cur = conn.cursor ( )
        cur.execute ("DROP TABLE IF EXISTS PETROL")
        cur.execute ("CREATE TABLE PETROL ( id INT AUTO_INCREMENT PRIMARY KEY ,
        AMOUNT FLOAT ,QUANTITY FLOAT ,Year VARCHAR(10) ,Date DATE")
        fp1 = open ("D:/Python/petrol/pdate/pdate.txt" , "rb+")
        while True:
            try :
                pdate = pickle.load (fp1)
                cur.execute ("INSERT INTO PETROL Date VALUES(?)" , (pdate))
            except EOFError :
                fp1.close()
        fp3 = open ("D:/Python/petrol/pyear/pyear.txt" , "rb+")
        while True:
            try :
                pyear = pickle.load (fp3)
                cur.execute ("INSET INTO PETROL Year VALUES(?)" , (pyear))
            except EOFError :
                fp3.close()
        fp4=open ("D:/Python/petrol/petrolamt/petrolamt.txt" , "rb+")
        while True:
            try :
                pamt = pickle.load (fp4)
                cur.execute ("INSERT INTO PETROL Amount VALUES(?)" , (pamt))
            except EOFError :
                fp4.close()

        fp5 = open ("D:/Python/petrol/petrolqty/petrolqty.txt" , "rb+")
        while True:
            try :
                pqty = pickle.load (fp5)
                cur.execute ("INSERT INTO PETROL Quantity VALUES(?)" , (pqty))
            except EOFError :
                fp5.close()
        conn.commit ( )

    except mysql.connector.Error as error :
        print ("Failed to create table in MySQL: {}".format (error))
    finally :
        if (conn.is_connected ( )) :
            cur.execute ("SELECT * FROM PETROL")
            for i in cur :
                print (i)
            cur.close ( )
            conn.close ( )
            print ("MySQL connection is closed")

indatabase()

CREATE TABLE PETROL...

Date DATE 后面缺少右括号
