使用 Python 在 MYSQL 数据库中创建表错误

Question

I wanted to create a database of my data which have been stored in files.For this I used file handling to read data from the stored files and input into the table of my database. But it shows error given below.

Is it the correct way to switch data storage option from files to database.

The error occured is given below -:

Traceback (most recent call last):

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

This is the code which reads data from files and then inputs in the database.

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()

Answer 1

on this line

CREATE TABLE PETROL...

you are missing the closing parenthesis after Date DATE
