| 956832836 | MDU6SXNzdWU5NTY4MzI4MzY= | 300 | Returning underlying cause for User Defined Functions | 71236 | closed | 0 | 1 | 2021-07-30T15:08:21Z | 2021-08-02T21:53:50Z | 2021-08-02T21:53:50Z | NONE | The sqlite3 client takes user defined functions and replaces the text with "user-defined function raised exception`" so it's not apparent what's gone wrong: ``` Unexpected error: user-defined function raised exception ``` As mentioned in https://code.djangoproject.com/ticket/29500 and https://stackoverflow.com/questions/45824209/how-to-get-an-error-kind-from-sqlite-create-function/45834923#45834923 the workaround for this is to enable callback tracebacks: ``` sqlite3.enable_callback_tracebacks(True) ``` It would be nice if https://sqlite-utils.datasette.io/en/stable/python-api.html#registering-custom-sql-functions either included a reference to `enable_callback_tracebacks` or if registering a user defined function set this flag automatically. | 140912432 | issue | {"url": "https://api.github.com/repos/simonw/sqlite-utils/issues/300/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | completed |
