Learn T-SQL With Erik: DISTINCT FROM?!

Description:
In this video, I delve into the exciting new 'DISTINCT FROM' syntax introduced in SQL Server 2022, which simplifies handling nulls in queries without resorting to complex or cumbersome conditions. I demonstrate how 'DISTINCT FROM' can streamline your T-SQL coding by providing a more elegant way to manage null values compared to traditional methods like 'EXISTS'. Additionally, I explore the potential of using 'DISTINCT FROM' for optional predicates and parameter handling, highlighting both its benefits and limitations. While it offers a neat solution in some cases, I also point out that its effectiveness is limited when dealing with more complex conditions involving logical operators or date ranges. Join me as we dive deeper into T-SQL best practices and explore the nuances of this new feature!
