我正在尝试将用scrapy刮下的数据保存到mysql中。但是，我有这些问题：
不再支持 MySQLdb . 所以，我必须使用
import pymysql pymysql.install_as_MySQLdb() 在 settings.py 文件
在Python3上 %s 已弃用，我必须使用 . 使用以下代码格式化：

def close(self, reason):
        csv_file = max(glob.iglob('*.csv'), key=os.path.getctime)       
        mydb = MySQLdb.connect(host='localhost',
                               user='demo',
                               passwd='123456',
                               db='testdb')
        cursor = mydb.cursor()

        csv_data = csv.reader(open(csv_file))

        row_count = 0
        for row in csv_data:
            if row_count != 0:
                cursor.execute("INSERT IGNORE INTO testtb(product, category) VALUES('{}','{}')".format(*row))
            row_count += 1

        mydb.commit()
        cursor.close()

我有以下错误

<bound method AutorSpider.close of <AutorSpider 'autor' at 0x7f64725d29b0>>

    packet.check_error()

    err.raise_mysql_exception(self._data)
  File "/home/pc/.local/lib/python3.6/site-packages/pymysql/err.py", line 109, in raise_mysql_exception
    raise errorclass(errno, errval)
pymysql.err.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'titulo del item numero 1' at line 1")

还有其他更简单/有效的方法吗？因为我保存的数据在最后的刮削任务，如果我得到更多的结果（3000条）也许这是一个问题，在未来与更大的网站？

转义字符串可以帮助你

def close(self, reason):
    csv_file = max(glob.iglob('*.csv'), key=os.path.getctime)       
    mydb = MySQLdb.connect(host='localhost',
                           user='demo',
                           passwd='123456',
                           db='testdb')
    cursor = mydb.cursor()

    csv_data = csv.reader(open(csv_file))

    row_count = 0
    for row in csv_data:
        if row_count != 0:
            product = mydb.escape_string(row[0])
            category = mydb.escape_string(row[1])
            #print category , product
            sql = 'INSERT IGNORE INTO testtb(product, category) VALUES ( "{}","{}")'.format(product,category)
            #print sql
            cursor.execute(sql)
            row_count += 1

    mydb.commit()
    cursor.close()
