Sqlalchemy nullslast
WebJun 30, 2024 · Basically, we can sort NULLs last whilst sorting non-NULL values in ascending order by supplying the highest possible value as a substitute for NULL values: SELECT *. FROM paintings. ORDER BY COALESCE(year, 2024); Here, we use 2024 as the highest possible value for the year column. WebSQL defines that NULL values should be placed together when sorting, but it does not specify whether they should be placed first or last. Even though both nullsfirst and nullslast are part of SQLAlchemy , they will raise an unexpected exception if the RDBMS that is being used does not support them.
