I'm working with a database with music listening information. Currently it has one large table `listens` that contains all information. I'm trying to normalize the database by extracting relevant columns to separate tables (`artists`, `tracks`, `albums`). Not every track has an album. A simplified demonstration with just `track_title` and `album_title` columns: ```ipython In [1]: import sqlite_utils In [2]: db = sqlite_utils.Database(memory=True) In [3]: db[""listens""].insert_all([ ...: {""id"": 1, ""track_title"": ""foo"", ""album_title"": ""bar""}, ...: {""id"": 2, ""track_title"": ""baz"", ""album_title"": None} ...: ], pk=""id"") Out[3]:
``` The track in the first row has an album, the second track doesn't. Now I extract album information into a separate column: ```ipython In [4]: db[""listens""].extract(columns=[""album_title""], table=""albums"", fk_column=""album_id"") Out[4]:
In [5]: list(db[""albums""].rows) Out[5]: [{'id': 1, 'album_title': 'bar'}, {'id': 2, 'album_title': None}] In [6]: list(db[""listens""].rows) Out[6]: [{'id': 1, 'track_title': 'foo', 'album_id': 1}, {'id': 2, 'track_title': 'baz', 'album_id': None}] ``` This behaves as expected -- the `album` table contains entries for both the existing album and the NULL album. The `listens` table has a foreign key only for the first row (since the album in the second row was empty). Now I want to extract the track information as well. Album information belongs to the track so I want to extract both columns to a new table. ```ipython In [7]: db[""listens""].extract(columns=[""track_title"", ""album_id""], table=""tracks"", fk_column=""track_id"") Out[7]:
In [8]: list(db[""tracks""].rows) Out[8]: [{'id': 1, 'track_title': 'foo', 'album_id': 1}, {'id': 2, 'track_title': 'baz', 'album_id': None}] In [9]: list(db[""listens""].rows) Out[9]: [{'id': 1, 'track_id': 1}, {'id': 2, 'track_id': None}] ``` Extracting to the `tracks` table worked fine (both tracks are present with correct columns). However, the `listens` table only has a foreign key to the newly created tracks for the first row, the foreign key in the second row is NULL. Changing the order of extracts doesn't help. I poked around in the source a bit and I believe [this line](https://github.com/simonw/sqlite-utils/blob/433813612ff9b4b501739fd7543bef0040dd51fe/sqlite_utils/db.py#L1737) (essentially comparing `NULL = NULL`) is the problem, but I don't know enough about SQL to create a reliable fix myself.",140912432,sqlite-utils,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/423/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed 1309542173,PR_kwDOCGYnMM47pwAb,455,"in extract code, check equality with IS instead of = for nulls",536941,fgregg,closed,0,,,,,3,2022-07-19T13:40:25Z,2022-08-27T14:45:03Z,2022-08-27T14:45:03Z,CONTRIBUTOR,simonw/sqlite-utils/pulls/455,"sqlite ""IS"" is equivalent to SQL ""IS NOT DISTINCT FROM"" closes #423",140912432,sqlite-utils,pull,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/455/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",0, 1352953535,PR_kwDOCGYnMM4950Az,473,Support entrypoints for `--load-extension`,9599,simonw,closed,0,,,,,1,2022-08-27T05:53:59Z,2022-08-27T05:55:52Z,2022-08-27T05:55:47Z,OWNER,simonw/sqlite-utils/pulls/473,"Refs #470 ---- :books: Documentation preview :books:: https://sqlite-utils--473.org.readthedocs.build/en/473/ ",140912432,sqlite-utils,pull,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/473/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",0, 1352932038,I_kwDOCGYnMM5QpBrG,470,Upgrade `--load-extension` to accept entrypoints like Datasette,9599,simonw,closed,0,,,8355157,3.29,6,2022-08-27T03:53:20Z,2022-08-27T05:55:49Z,2022-08-27T05:55:48Z,OWNER,,"Imitate: - https://github.com/simonw/datasette/pull/1789 ``` # would load default entrypoint like before datasette data.db --load-extension ext # loads the extensions with the ""sqlite3_foo_init"" entrpoint datasette data.db --load-extension ext:sqlite3_foo_init # loads the extensions with the ""sqlite3_bar_init"" entrpoint datasette data.db --load-extension ext:sqlite3_bar_init ```",140912432,sqlite-utils,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/470/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed 1352946135,I_kwDOCGYnMM5QpFHX,472,Reuse the locals/globals fix from --functions for other code accepting options,9599,simonw,closed,0,,,8355157,3.29,2,2022-08-27T05:12:05Z,2022-08-27T05:20:12Z,2022-08-27T05:20:12Z,OWNER,,"I figured out a workaround for the ugly `global x` hack here: - https://github.com/simonw/sqlite-utils/issues/471#issuecomment-1229120653",140912432,sqlite-utils,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/472/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed 1352931464,I_kwDOCGYnMM5QpBiI,469,sqlite-utils rows --order option,9599,simonw,closed,0,,,8355157,3.29,1,2022-08-27T03:49:51Z,2022-08-27T04:30:49Z,2022-08-27T04:10:32Z,OWNER,,"For consistency with `search`: https://sqlite-utils.datasette.io/en/stable/cli-reference.html#search ``` -o, --order TEXT Order by ('column' or 'column desc') ``` I wanted to run `sqlite-utils rows db.db mytable --order 'rowid desc'` to see the most recently imported rows.",140912432,sqlite-utils,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/469/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
