Importing repeated values into lookup tables currently requires the Python API or a separate normalization step. Add repeatable
--extract COLUMNoptions toinsertandupsert, using the existingextracts=implementation and the interface prototyped in #352.Each selected column uses a same-name lookup table with
idandvaluecolumns. Repeated values reuse the same lookup ID, and nulls stay null. New target tables receive integer foreign keys; existing target schemas are preserved. CSV/TSV type inference continues for other columns and keeps extracted foreign keys as integers. Imports without the option retain their current behavior.Includes usage examples, generated CLI help and coverage for JSON, newline JSON, CSV, TSV,
--code, repeated extracts, batching, upserts, nulls, strict tables, type overrides, quoted identifiers, existing schemas and invalid input.Validation: offline focused and full pytest suites, Black, Flake8, mypy, Cog and the added documentation section on Python 3.11.6 / SQLite 3.42.0. Other Python/SQLite versions and upstream CI have not been run for this change.
