scrapy写入sql server数据库报错Error: (207）如何解决？

scrapy写入sql server数据库报错pymssql._pymssql.ProgrammingError: (207, b"Invalid column name '\xe7\xba\xb3\xe5\x85\xb0\xe6\x80\xa7\xe5\xbe\xb7\xe3\x80\x8a\xe5\xa6\x82\xe6\xa2\xa6\xe4\xbb\xa4\xc2\xb7\xe9\xbb\x84\xe5\x8

class PoemscrapyPipeline:

    #写入数据库
    def __init__(self):
        self.connect=pymssql.connect(
            host='DESKTOP-I0TJ9UD',
            port=1433,
            database='poemdb',
            user='robot',
            password='123456,
            charset='utf8',
            autocommit = True
        )
        self.cursor = self.connect.cursor()

    def process_item(self, item, spider):
        #写入数据库
        self.cursor.execute('INSERT INTO sentence(source,sentence,url,content) VALUES ("{}","{}","{}","{}")'
                         .format(item['source'], item['sentence'], item['url'], item['content']))
        self.connect.commit()
        return item

    def close_spider(self,spider):
        self.cursor.close()
        self.connect.close()

运行之后爬取信息成功，但是无法写入数据库，报错如下：

pymssql._pymssql.ProgrammingError: (207, b"Invalid column name '\xe7\xba\xb3\xe5\x85\xb0\xe6\x80\xa7\xe5\xbe\xb7\xe3\x80\x8a\xe5\xa6\x82\xe6\xa2\xa6\xe4\xbb\xa4\xc2\xb7\xe9\xbb\x84\xe5\x8

我自己查的结果都说是列名不对，我和数据库里的列名反复核对过了，顺序也核对过了，也试过新建一个数据库，但都没有解决，希望有人可以帮我看看！！
