问题
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?
回答1:
Do you have another connection elsewhere in your code that you use to begin a transaction that is still active (not committed) when you try to commit the operation that fails?
回答2:
Because your database is use by another process or connection. If you need real concurrency, use a real RDBMS.
回答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.
