| 1071531082 | I_kwDOCGYnMM4_3kRK | 349 | A way of creating indexes on newly created tables | 9599 | open | 0 | 3 | 2021-12-05T18:56:12Z | 2021-12-07T01:04:37Z | OWNER | I'm writing code for https://github.com/simonw/git-history/issues/33 that creates a table inside a loop: ```python item_pk = db[item_table].lookup( {"_item_id": item_id}, item_to_insert, column_order=("_id", "_item_id"), pk="_id", ) ``` I need to look things up by `_item_id` on this table, which means I need an index on that column (the table can get very big). But there's no mechanism in SQLite utils to detect if the table was created for the first time and add an index to it. And I don't want to run `CREATE INDEX IF NOT EXISTS` every time through the loop. This should work like the `foreign_keys=` mechanism. | 140912432 | issue | {"url": "https://api.github.com/repos/simonw/sqlite-utils/issues/349/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} |
