可以只使用一个游标对数据库执行所有操作吗？

Question

I have a program, which must work with database (and it can work in few threads). I wrote a special class, which starts from:

class DataBase:
    def __init__(self):
         self.connection = sqlite3.connect("some_db.db", check_same_thread=False)
         self.cursor = self.connection.cursor()

Is it okay to use such class? Or I should go another way and use few cursors? My program works fine now and I didn't notice any problems, but I'm not sure can it lead to big problems in future

Answer 1

I have sqlite3 working in classes and I don't need it to be self-ed. Ive got it like...

connection = sqlite3.connect("some_db.db")
c = connection.cursor()

Yeah I think its fine, until you need multiple databases where all you need to do is name you connection and cursors something different like...

connection2 = sqlite3.connect("another_db.db")
c2 = connection2.cursor()

You can have them running at the same time too. Just remember to commit and close when you don't need them anymore.
