Lead and Lag Functions in SQL Server 2012
IntroductionLead Function in SQL Server 2012Lag Function in SQL Server 2012ConclusionHave you ever been in a situation where you needed to write a query that needed to do comparisons or access data from the subsequent rows along with the data from the current row? This article discusses different ways to write these types of queries and more specifically examines LEAD and LAG analytics functions, which were introduced with SQL Server 2012, and helps you understand how leveraging these functions can aid you in such situations.Accessing Prior or Subsequent RowsSQL Server 2012 isql Conditional lead/lag function PostgreSQL? Stack
You can combine the aggregate FILTER clause with the OVER clause of window functions. However The FILTER clause itself can only work with values from the current row. More importantly, FILTER is not implemented for pure window functions like lead () or lag () in Postgres 9.6 (yet) only for aggregate functions.
