| 593751293 | MDU6SXNzdWU1OTM3NTEyOTM= | 97 | Adding a "recreate" flag to the `Database` constructor | 1448859 | closed | 0 | 4 | 2020-04-04T05:41:10Z | 2020-04-15T14:29:31Z | 2020-04-13T03:52:29Z | NONE | I have a [script](https://github.com/betatim/binder-datasette/blob/master/create-db.ipynb) that imports data into a sqlite DB. When I re-run that script I'd like to remove the existing sqlite DB, instead of adding to it. The pragmatic answer is to add the check and file deletion to my script. However I thought it would be easy and useful for others to add a `recreate=True` flag to `db = sqlite_utils.Database("binder-launches.db")`. After taking a look at the code for it I am not so sure any more. This is because the connection string could be a URL (or "connection string") like `"file:///tmp/foo.db"`. I don't know what the equivalent of `os.path.exists()` is for a connection string or how to detect that something is a connection string and raise an error "can't use recreate=True and conn_string at the same time". Does anyone have an idea/suggestion where to start investigating? | 140912432 | issue | {"url": "https://api.github.com/repos/simonw/sqlite-utils/issues/97/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | completed |
