Analytic functions (Transact-SQL)
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
Azure Synapse Analytics
Analytics Platform System (PDW)
Azure SQL Edge
SQL Server supports these analytic functions:
- CUME_DIST (Transact-SQL)
- FIRST_VALUE (Transact-SQL)
- LAG (Transact-SQL)
- LAST_VALUE (Transact-SQL)
- LEAD (Transact-SQL)
- PERCENT_RANK (Transact-SQL)
- PERCENTILE_CONT (Transact-SQL)
- PERCENTILE_DISC (Transact-SQL)
Analytic functions calculate an aggregate value based on a group of rows. Unlike aggregate functions, however, analytic functions can return multiple rows for each group. Use analytic functions to compute moving averages, running totals, percentages or top-N results within a group.
