CNNYLone() does not return null, it will throw when it doesn't find a result.LrowsRead you get is not the number of results. It's the number of rows read by SQLite to satisfy your query. So, if you do joins, scans, etc, and only end up with 1 row, you are not just charged for 1 row, but all the rows that had to be read to answer your query. YYYY

LIf you invoke put() (or delete()) multiple times without performing any await in the meantime, the operations will automatically be combined and submitted atomically. In case of a machine failure, either all of the writes will have been stored to disk or none of the writes will have been stored to disk.

However, is that just for the old get()put()fetch

.exec() method does the prepare statements for you. Soon they will be cached automatically as well.L.sql.exec()If you invoke put() (or delete()) multiple times without performing any await in the meantime, the operations will automatically be combined and submitted atomically.
