targetDb.exec('CREATE TABLE data(key INTEGER PRIMARY KEY, value TEXT)');
const session = sourceDb.createSession();
const insert = sourceDb.prepare('INSERT INTO data (key, value) VALUES (?, ?)');
insert.run(1, 'hello');
insert.run(2, 'world');
const changeset = session.changeset();
targetDb.applyChangeset(changeset);
