Re: Database is locked
Typically, such a message can appear when several users simultaneously try to change data in the DBMS SQLite. In this case, it is necessary to switch to the use of MySQL to fully support the multi-user mode.
The second typical case is if you get compiler errors during development, but the application still runs and can keep the database file from changing. In this case, you need to open Task Manager and kill all processes that have a connection to the database file.
