If you exit IntelliJ IDEA and open it again, you must provide the password again.įor session: password is saved only for the current connection session with a database (until you disconnect from it). Until restart: password is saved only for the current IntelliJ IDEA run. ![]() Never: password is prompted each time you establish a connection with a database. You can select the following options for storing your password: Alternatively, select a data source and press Ctrl+F2. If you want to close a database connection, select a data source and click the Deactivate button on the toolbar. Names of data sources that interact with a database are shown in the Database tool window with a little green circle. When you create a database connection, IntelliJ IDEA connects to a database automatically to receive database objects. Open the Installed tab, find the Database tools and SQL plugin, and select the checkbox next to the plugin name. Press Ctrl+Alt+S to open the IDE settings and select Plugins. The Database tools and SQL plugin is available only in IntelliJ IDEA Ultimate. If the relevant features aren't available, make sure that you didn't disable the plugin. This functionality relies on the Database tools and SQL plugin, which is bundled and enabled in IntelliJ IDEA by default. If you disconnect from in-memory database, the database gets destroyed, so then you don't need to reset those.Configure database connections Enable the Database tools and SQL plugin Group 3 are for example schema_version, user_version, maybe some others, you need to look it up. ![]() If you don't disconnect, you will need to reset those to defaults manually. These pragmas are always set to defaults when opening new connection to the database. Group 2 are for example cache_size, recursive_triggers, jurnal_mode, foreign_keys, busy_timeout, etc. You should not need to reset pragmas from group 1. The encoding is defined at creation time and cannot be modified later. The page_count cannot be changed by user, but it changes automatically when adding data (obviously). For example page_size can be changed prior to "VACUUM", so the new page size will be set then. Those are definied at database creation moment and usualle cannot be modified later, with some exceptions. ![]() Group 1 are for example page_size, page_count, encoding, etc. defined dynamically, per database, mutable.defined dynamically, per connection, mutable.defined initially, immutable, or very limited mutability.Note, that pragmas in SQLite can be divided to 3 groups: If your threads don't touch pragmas explicitly, then only "schema_version" pragma can be changed silently, but if your threads can change pragmas, well, then you have to go through the list on and write "reset" function which will set each and every pragma value to it's initial value (you need to read default values at the begining). If there are some other limitations and you cannot do it the way above, then you were already pretty close to have a complete solution. While you have exclusive access to the database connection - why not closing and re-opening it? Therefore even you have multiple threads working on that database, there need to be a "stop the world" mutex (or something like that), so the reset can be performed. If you want to have some kind of "reset" function, you must assume that no other threads can interrupt that function - otherwise any method will fail. ![]() It flushes any database data and also per-connection settings. If you use in-memory database, the fastest and most reliable way is to close and re-establish sqlite connection.
