When i try to import this file via the `insert` command I get the following error: ``` sqlite-utils insert database.db table_name file_with_large_column.csv Traceback (most recent call last): File "/usr/local/bin/sqlite-utils", line 10, in <module> sys.exit(cli()) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 829, in __call__ return self.main(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 782, in main rv = self.invoke(ctx) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 1259, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 1066, in invoke return ctx.invoke(self.callback, **ctx.params) File "/usr/local/lib/python3.7/site-packages/click/core.py", line 610, in invoke return callback(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/sqlite_utils/cli.py", line 774, in insert default=default, File "/usr/local/lib/python3.7/site-packages/sqlite_utils/cli.py", line 705, in insert_upsert_implementation docs, pk=pk, batch_size=batch_size, alter=alter, **extra_kwargs File "/usr/local/lib/python3.7/site-packages/sqlite_utils/db.py", line 1852, in insert_all first_record = next(records) File "/usr/local/lib/python3.7/site-packages/sqlite_utils/cli.py", line 703, in <genexpr> docs = (decode_base64_values(doc) for doc in docs) File "/usr/local/lib/python3.7/site-packages/sqlite_utils/cli.py", line 681, in <genexpr> docs = (dict(zip(headers, row)) for row in reader) _csv.Error: field larger than field limit (131072) ``` Built with the docker image `datasetteproject/datasette:0.54` with the following versions: ``` # sqlite-utils --version sqlite-utils, version 3.4.1 # datasette --version datasette, version 0.54 ``` It appears this is a [known issue](https://stackoverflow.com/a/54517228/2761423) reading in csv files in python and [doesn't look to be modifiable](https://github.com/python/cpython/blob/ea46579067fd2d4e164d6605719ffec690c4d621/Modules/_csv.c#L1685) through system / env vars (i may be very wrong on this). Noting that using sqlite3 `import` command work without error (not using the python csv reader) ``` sqlite3 database.db sqlite> .mode csv sqlite> .import file_with_large_column.csv table_name ``` Sadly I couldn't see an easy way around this while using the cli as it appears this value needs to be changed in python code. FWIW I've switched to using https://datasette.io/tools/csvs-to-sqlite for importing csv data and it's working well. Finally, I'm loving https://datasette.io/ thank you very much for an amazing tool and data ecosytem 🙇♀️ | 140912432 | issue | {"url": "https://api.github.com/repos/simonw/sqlite-utils/issues/227/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | completed |
