sqlite3.OperationalError: database is locked

Question

I'm trying to insert all values of a list to my sqlite3 database. When I simulate this query by using the python interactive interpreter, I am able to insert the single value to DB properly. But my code fails while using an iteration:

...
connection=lite.connect(db_name)
cursor=connection.cursor()
for name in match:
         cursor.execute("""INSERT INTO video_dizi(name) VALUES (?)""",(name,))
connection.commit()
...

error:cursor.execute("""INSERT INTO video_dizi(name) VALUES (?)""",(name,))
sqlite3.OperationalError: database is locked

Any way to overcome this problem?

Answer 1

当您尝试提交失败的操作时，您在代码中的其他位置是否有另一个用于开始仍处于活动状态（未提交）的事务的连接？

Answer 2

Because your database is use by another process or connection. If you need real concurrency, use a real RDBMS.

Answer 3

As this error can happen because you have opened your site.db or database file in DBbrowser type application to view in interactive database interface. Just close that it will work fine.
