如何插入变量到数据库表sqlite3 - 蟒蛇

Question

每当我尝试运行下面的代码，我得到一个错误，说theres没有这样的列“title_data”，我真的很困惑，因为“标题”是不是“title_data”列

def insertData(self): 
    title_Data = self.edit_title.text() 
    year_Data = self.edit_year.text() 
    rating_Data = self.edit_rating.text() 


    connection = sqlite3.connect('films.db') 
    try: 
     connection.execute("INSERT INTO FILMS (TITLE,YEAR,RATING) VALUES(title_Data,year_Data,rating_Data)") 


    except sqlite3.IntegrityError: 
     print("You have already stored this data") 
    connection.commit() 
    connection.close() 

Answer 1

你没有正确传递你的变量。取而代之的

connection.execute("INSERT INTO FILMS (TITLE,YEAR,RATING) VALUES(title_Data,year_Data,rating_Data)") 

您应该使用

connection.execute("INSERT INTO FILMS (TITLE,YEAR,RATING) VALUES(?,?,?)", (title_Data,year_Data,rating_Data)) 

见execute()的文档获取更多信息。
