使用Jupyter Notebook的MySQL INSERT INTO错误：语法无效

Question

以下代码在Jupyter Notebook中运行。

import pandas
import pymysql

connection = pymysql.connect(host='localhost', user='root', password='123456', database='sakila')

cursor=connection.cursor()

insert_query= INSERT INTO film_text (film_id, title, description) VALUES ('1001','ZZZ ZORRO','Zorro must Fight a Womanizer in Berlin');

cursor.execute(insert_query)

connection.commit（）

错误：   文件“”，第7行     insert_query = INSERT INTO film_text（film_id，title，description）值（“ 1001”，“ ZZZ ZORRO”，“ Zorro必须与柏林的女化者作战”）；                            ^ SyntaxError：语法无效

Answer 1

insert_query的类型将是一个字符串。

insert_query = "INSERT INTO film_text (film_id, title, description) VALUES ('1001','ZZZ ZORRO','Zorro must Fight a Womanizer in Berlin')"

Answer 2

您也可以像这样直接编写代码

cursor.execute("""INSERT INTO film_text (film_id, title, description) VALUES ('1001','ZZZ ZORRO','Zorro must Fight a Womanizer in Berlin'""");

Answer 3

您忘记将查询用引号引起来。下面的代码应该可以正常工作：

import pandas
import pymysql

connection = pymysql.connect(host='localhost', user='root', password='123456', database='sakila')

cursor=connection.cursor()

insert_query= "INSERT INTO film_text (film_id, title, description) VALUES ('1001','ZZZ ZORRO','Zorro must Fight a Womanizer in Berlin');"

cursor.execute(insert_query)

Answer 4

您应该在查询字符串中加上引号

insert_query= "INSERT INTO film_text (film_id, title, description) 
      VALUES ('1001','ZZZ ZORRO','Zorro must Fight a Womanizer in Berlin')";

Answer 5

如果不打算对来自 python 的数据做一些非常高级的事情，也许最好使用 jupyter kernel 来使用纯 SQL 中的数据库。
