1353074021 | I_kwDOCGYnMM5QpkVl | 474 | Add an option for specifying column names when inserting CSV data | 14294 | open | 0 | 3 | 2022-08-27T15:29:59Z | 2022-08-31T03:42:36Z | NONE | https://sqlite-utils.datasette.io/en/stable/cli.html#csv-files-without-a-header-row > The first row of any CSV or TSV file is expected to contain the names of the columns in that file. > If your file does not include this row, you can use the `--no-headers` option to specify that the tool should not use that fist row as headers. > If you do this, the table will be created with column names called `untitled_1` and `untitled_2` and so on. You can then rename them using the `sqlite-utils transform ... --rename` command. It would be nice to be able to specify the column names when importing CSV/TSV without a header row, via an extra command line option. (renaming a column of a large table can take a long time, which makes it an inconvenient workaround) | 140912432 | issue | { "url": "https://api.github.com/repos/simonw/sqlite-utils/issues/474/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |

1227571375 | I_kwDOCGYnMM5JK0Cv | 431 | Allow making m2m relation of a table to itself | 738408 | open | 0 | 3 | 2022-05-06T08:30:43Z | 2022-06-23T14:12:51Z | NONE | I am building a database, in which one of the tables has a many-to-many relationship to itself. As far as I can see, this is not (yet) possible using `.m2m()` in sqlite-utils. This may be a bit of a niche use case, so feel free to close this issue if you feel it would introduce too much complexity compared to the benefits. Example: suppose I have a table of people, and I want to store the information that John and Mary have two children, Michael and Suzy. It would be neat if I could do something like this: ```python from sqlite_utils import Database db = Database(memory=True) db["people"].insert({"name": "John"}, pk="name").m2m( "people", [{"name": "Michael"}, {"name": "Suzy"}], m2m_table="parent_child", pk="name" ) db["people"].insert({"name": "Mary"}, pk="name").m2m( "people", [{"name": "Michael"}, {"name": "Suzy"}], m2m_table="parent_child", pk="name" ) ``` But if I do that, the many-to-many table `parent_child` has only one column: ``` CREATE TABLE [parent_child] ( [people_id] TEXT REFERENCES [people]([name]), PRIMARY KEY ([people_id], [people_id]) ) ``` This could be solved by adding one or two keyword_arguments to `.m2m()`, e.g. `.m2m(..., left_name=None, right_name=None)` or `.m2m(..., names=(None, None))`. | 140912432 | issue | { "url": "https://api.github.com/repos/simonw/sqlite-utils/issues/431/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |
