csvs-to-sqlite big_csv_file.csv -c country output.db
This will turn the `country` column in the resulting table into a integer foreign key against a new `country` table. You can see an example of what that looks like here: https://san-francisco.datasettes.com/registered-business-locations-3d50679/Business+Corridor was extracted from https://san-francisco.datasettes.com/registered-business-locations-3d50679/Registered_Business_Locations_-_San_Francisco?Business%20Corridor=1

* Rename a table
* Rename a column
* Add a column
Notably, it cannot drop columns - so tricks like ""add a float version of this text column, populate it, then drop the old one and rename"" won't work.
The docs here https://www.sqlite.org/lang_altertable.html#making_other_kinds_of_table_schema_changes describe a way of implementing full alters safely within a transaction, but it's fiddly.
1. Create new table
2. Copy data
3. Drop old table
4. Rename new into old
It would be great if `sqlite-utils` provided an abstraction to help make these kinds of changes safely.",140912432,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/114/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
