Another one of the database options which doesn’t serve any real purpose. As shown in this video the setting is overridden by session level settings so it doesn’t make sense to set it at Database level. This option default the NULLAbility of columns when creating the table or altering it. When set to off it defaults new columns to NOT NULL but unfortunately it only works at the session level and not the database level.

Like AUTO UPDATE STATS you don’t want to rely on this setting. In fact best practice dictates that you explicitly call out the NULLABILITY of columns when creating them.
