1868713944 | I_kwDOCGYnMM5vYk_Y | 588 | `table.get(column=value)` option for retrieving things not by their primary key | 9599 | open | 0 | 1 | 2023-08-28T00:41:23Z | 2023-08-28T00:41:54Z | OWNER | This came up working on this feature: - https://github.com/simonw/llm/pull/186 I have a table with this schema: ```sql CREATE TABLE [collections] ( [id] INTEGER PRIMARY KEY, [name] TEXT, [model] TEXT ); CREATE UNIQUE INDEX [idx_collections_name] ON [collections] ([name]); ``` So the primary key is an integer (because it's going to have a huge number of rows foreign key related to it, and I don't want to store a larger text value thousands of times), but there is a unique constraint on the `name` - that would be the primary key column if not for all of those foreign keys. Problem is, fetching the collection by name is actually pretty inconvenient. Fetch by numeric ID: ```python try: table["collections"].get(1) except NotFoundError: # It doesn't exist ``` Fetching by name: ```python def get_collection(db, collection): rows = db["collections"].rows_where("name = ?", [collection]) try: return next(rows) except StopIteration: raise NotFoundError("Collection not found: {}".format(collection)) ``` It would be neat if, for columns where we know that we should always get 0 or one result, we could do this instead: ```python try: collection = table["collections"].get(name="entries") except NotFoundError: # It doesn't exist ``` The existing `.get()` method doesn't have any non-positional arguments, so using `**kwargs` like that should work: https://github.com/simonw/sqlite-utils/blob/1260bdc7bfe31c36c272572c6389125f8de6ef71/sqlite_utils/db.py#L1495 | 140912432 | issue | { "url": "https://api.github.com/repos/simonw/sqlite-utils/issues/588/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |
