The Checking out the Window Clause in Azure SQL and SQL Server 2022 is a new feature that allows users to query data within a moving window of time. This clause allows users to specify an upper bound and lower bound for their time window, as well as an offset so they can easily adjust the size of the window.
The feature also enables you to define multiple windows with different sizes or offsets, allowing more flexibility when working with temporal data.

Additionally, it helps reduce unnecessary scanning of irrelevant data by quickly finding records within specified boundaries without having to manually filter through all available rows in a table.
