1733198948 I_kwDOCGYnMM5nToRk 555 Filter table by a large bunch of ids 10843208 open 0     1 2023-05-31T00:29:51Z 2023-06-14T22:01:57Z   NONE   Hi! this might be a question related to both SQLite & sqlite-utils, and you might be more experienced with them. I have a large bunch of ids, and I'm wondering which is the best way to query them in terms of performance, and simplicity if possible. The naive approach would be something like `select * from table where rowid in (?, ?, ?...)` but that wouldn't scale if ids are >1k. Another approach might be creating a temp table, or in-memory db table, insert all ids in that table and then join with the target one. I failed to attach an in-memory db both using sqlite-utils, and plain sql's execute(), so my closest approach is something like, ```python def filter_existing_video_ids(video_ids): db = get_db() # contains a "videos" table db.execute("CREATE TEMPORARY TABLE IF NOT EXISTS tmp (video_id TEXT NOT NULL PRIMARY KEY)") db["tmp"].insert_all([{"video_id": video_id} for video_id in video_ids]) for row in db["tmp"].rows_where("video_id not in (select video_id from videos)"): yield row["video_id"] db["tmp"].drop() ``` That kinda worked, I couldn't find an option in sqlite-utils's `create_table()` to tell it's a temporary table. Also, `tmp` table is not dropped finally, neither using `.drop()` despite being created with the keyword `TEMPORARY`. I believe it should be automatically dropped after connection/session ends though I read. 140912432 issue     {"url": "https://api.github.com/repos/simonw/sqlite-utils/issues/555/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0}
