如何将变量插入数据库表sqlite3 - Python

Question

每当我尝试运行以下代码时，我都会收到错误消息，说没有这样的列＆＃34; title_data＆＃34;，我真的很困惑因为＆＃34; TITLE＆＃34;列不是＆＃34; title_data＆＃34;

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

您没有正确传递变量。而不是

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

你应该使用

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