我有这个查询

        self.cursor.execute("""INSERT IGNORE INTO 
                        groups 
                        (
                            name,
                            builder_id,
                            content,city,
                            location,price,
                            target,
                            project_completion,

                            verify_id
                        ) 
                        VALUES 
                        (

                        );""", 
                       (
                            item['name'],
                            builder_id,
                            item['content'],
                            item['city'],
                            item['address'],
                            item['price'],
                            item['possession_date']
                        )
        )

我正在使用Scrapy抓取一些数据并放入一个mysql数据库。我一直在收到语法错误

                                18,
                                ("'friend' at line 19

18是builder_id和friend ...是内容字段的开头任何帮助??

execute（）方法只占用1个单一参数。

cursor.execute('insert into a ("a", "b") values (1,2)')

所以，不应该是＆＃39;＆＃39;在你的参数中。你可以试试这个

self.cursor.execute("""INSERT IGNORE INTO 
                    groups 
                    (
                        name,
                        builder_id,
                        content,city,
                        location,price,
                        target,
                        project_completion,
                        creator_id,verified,
                        live,
                        updater_id,
                        verify_id
                    ) 
                    VALUES 
                    (
                        %s,
                        %s,
                        %s,
