    Sets the default numerical precision policy used by queries created on this database connection to precisionPolicy. In case you wanted to create a permanent SQLite database on disk, you have to pass a full file path to setDatabaseName. I hope you enjoyed this tutorial explaining how to embed a database in your application with SQLite and Qt. Sets the connection's database name to name. Accept all cookies Customize settings.
