# Ql Driver * Supports both in-memory and file ql databases, with the URL schemes `ql+file://` and `ql+memory://` * In-memory driver is not of much use, since the database is destroyed once the migration operation finishes, but is included for completeness. * Stores migration version details in automatically generated table ``schema_migrations``. ## Usage ```bash migrate -url ql+file://./data.db -path ./migrations create add_field_to_table migrate -url ql+file://./data.db -path ./db/migrations up migrate help # for more info ``` ## Authors * Sam Willcocks, https://github.com/wlcx
