Python CSV和SQLITE具有不同的列和值

我将csv文件导入Python并尝试使用SQLLite。但是当我创建表时，列和值都被更改了。例如，在“总体”列中显示值“asin”。reviewerID列收到值“总体”等等。 如何修复它

class csvrd(object):
    def csvFile(self):

        self.readFile('reviews.csv')

    def readFile(self, filename):
        conn = sqlite3.connect('amazonReviews.db')
        cur = conn.cursor()             
        cur.execute("""CREATE TABLE IF NOT EXISTS amazonReviews(reviewerID varchar, asin INT,reviewerName varchar,reviewText varchar, overall INT,summary varchar,unixReviewTime INTEGER,reviewTime INTEGER,helpful INT,total INT)""")

        filename.encode('utf-8')
        print("Amazon Reviews table executed")
        with open(filename) as f:
            reader = csv.reader(f)
            for field in reader:
                cur.execute("INSERT INTO amazonReviews VALUES (?,?,?,?,?,?,?,?,?,?);", field)

        print("CSV Loaded into SQLite")
        conn.commit()
        conn.close()

c = csvrd().csvFile()


con = sqlite3.connect('amazonReviews.db')

pd.read_sql_query("SELECT * FROM amazonReviews LIMIT 5", con)

预期：

    reviewerID  asin    reviewerName    reviewText  overall summary unixReviewTime  reviewTime  helpful total
0   A1EE2E3N7PW666  B000GFDAUG  Aaron L. Allen "Orgazmo1009"    CA Lewsi' review should be removed. he's revie...   5   Stupid  1202256000  02 6, 2008  0   0

实际：

    asin    overall reviewText  reviewTime  reviewerID  reviewerName    summary unixReviewTime  helpful total

如果表已经存在，并且列的结果顺序为“实际”的话，就会发生这种情况。由于“创建”sql中的“如果不存在”，将不会创建表。由于清单类型，数据将在没有“类型”投诉的情况下加载
