如何插入變量到數據庫表sqlite3 - 蟒蛇

Question

每當我嘗試運行下面的代碼，我得到一個錯誤，說theres沒有這樣的列「title_data」，我真的很困惑，因爲「標題」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

你沒有正確傳遞你的變量。取而代之的

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

您應該使用

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

見execute()的文檔獲取更多信息。
