[英]How to insert variable to database table sqlite3 - Python
Whenever i try to run the following code i get an error saying that theres no such column "title_data", im really confused because "TITLE" is the column not "title_data" 每当我尝试运行以下代码时,我都会收到一条错误消息,说没有此类列“ title_data”,我真的很困惑,因为“ TITLE”是该列而不是“ title_data”
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()
You're not passing your variables correctly. 您没有正确传递变量。 Instead of
代替
connection.execute("INSERT INTO FILMS (TITLE,YEAR,RATING) VALUES(title_Data,year_Data,rating_Data)")
You should use 你应该用
connection.execute("INSERT INTO FILMS (TITLE,YEAR,RATING) VALUES(?,?,?)", (title_Data,year_Data,rating_Data))
See the docs for execute()
for more information. 有关更多信息,请参见
execute()
的文档。
