You can do this by starting it without passing any files or by using the new  --memory  option to  datasette serve . This can be useful for experimenting with SQLite queries that do not access any data, such as  SELECT 1+1  or  SELECT sqlite_version() .", "breadcrumbs": "[\"Changelog\", \"0.28 (2019-05-19)\"]", "references": "[{\"href\": \"https://github.com/python/black\", \"label\": \"Black coding style\"}, {\"href\": \"https://github.com/simonw/datasette/pull/449\", \"label\": \"#449\"}, {\"href\": \"https://github.com/simonw/datasette/issues/433\", \"label\": \"#433\"}, {\"href\": \"https://github.com/simonw/datasette/commit/583b22aa28e26c318de0189312350ab2688c90b1\", \"label\": \"583b22a\"}, {\"href\": \"https://github.com/simonw/datasette/commit/78e45ead4d771007c57b307edf8fc920101f8733\", \"label\": \"78e45ea\"}, {\"href\": \"https://github.com/simonw/datasette/issues/429\", \"label\": \"#429\"}, {\"href\": \"https://github.com/simonw/datasette/issues/428\", \"label\": \"#428\"}, {\"href\": \"https://github.com/simonw/datasette/issues/288\", \"label\": \"#288\"}, {\"href\": \"https://github.com/simonw/datasette/issues/435\", \"label\": \"#435\"}, {\"href\": \"https://github.com/simonw/datasette/issues/462\", \"label\": \"#462\"}, {\"href\": \"https://github.com/simonw/datasette/issues/465\", \"label\": \"#465\"}]"}
