I suspect that SQLite Database Browser has some optimisations inbuilt and hence its performance. The big O back-of-the-napkin calculation confirms this creating the index (O (NlogN)) and then using it (some O (logN)) ends up being asymptotically way more expensive than simply scanning the table (O (N)) (and, practically, WAY more expensive). Whereas users on version 3.7.11 or later have the luxury of letting Mathematica map to the new syntax and thereby not having to explicitly start and end the transaction for the bulk insert. The query as run on 3.7.15 takes about 5 seconds with no indices. ![]() This meant that users on SQLite prior to 3.7.11 have to explicitly state SQLBeginTransaction and SQLCommitTransaction to perform an optimised bulk insert, as SQLite does not support a single batch insert SQL syntax. As I tried it the first time, I was a bit annoyed for the extra step to run the generated SELECT script. It runs on Windows, Mac and Linux with a more polished user interface and a higher update frequency. ![]() Mythic, an AI chip startup that last November reportedly ran out of capital, rose from. Searching around, one would find SQLite Release Notes for 3.7.11 for which bulk insert is supported for the INSERT syntax. SQLiteStudio is very similar to DB Browser for SQLite. AI chip startup Mythic rises from the ashes with 13M, new CEO. The result showed a correctly optimised bulk insert which lead one to believe that something must be different between the versions. I installed a fresh copy of SQLite, version 3.7.16.1 and ran the code molekyla777 has provided. ![]() Firstly, a bit about SQLite insert performances:īoth of these state the fact that SQLite wraps every insert statement with a transaction and that the run times can be up to 270x faster simply by wrapping the inserts in one transaction.
