SQL语句语法有问题了~

1、有一个方法能帮助我们更快的发现问题，就是输出自己的SQL语句：

输出Python中的MySQL插入语句：

insert_sql = "INSERT INTO db_writers (writer_id, writer_name_en, writer_name, writer_avatars, writer_alt) VALUES ({},{},{},{},{});".format(writer_id, writer_name_en, writer_name, writer_avatars, writer_alt)
print(insert_sql)

运行输出的SQL结果：

INSERT INTO db_writers ( writer_id, writer_name_en, writer_name, writer_avatars, writer_alt )
VALUES
    (
        1047973,
        Frank Darabont,弗兰克·德拉邦特,
    http :// img3.doubanio.com / VIEW / celebrity / s_ratio_celebrity / public / p230.jpg,
    https :// movie.douban.com / celebrity / 1047973 /);

除了writer_id是int类型，其他字段都是varchar类型的，一看问题就明了了，varchar类型的是要用双引号括起来的，是因为我的SQL语句在使用{}的时候，在除了writer_id对应的{}外忘记用 ' ' 包起来了，本来应该用'{}'的。

"INSERT INTO db_writers (writer_id, writer_name_en, writer_name, writer_avatars, writer_alt) VALUES ('{}','{}','{}','{}','{}');".format(writer_id, writer_name_en, writer_name, writer_avatars, writer_alt)
                

这样便不会报错了

同时有时候在字符串内容中有 ' 比如：' Alia ' s '也会导致报错，这时候如果还要插入到数据库的话需要转义：

比如：

original_title = res['original_title'].replace("\'", "\\\'")
