Analytic Functions (Transact-SQL)

[!INCLUDEtsql-appliesto-ss2012-all_md]

SQL Server supports the following analytic functions. Analytic functions compute an aggregate value based on a group of rows. However, unlike aggregate functions, they can return multiple rows for each group. You can use analytic functions to compute moving averages, running totals, percentages or top-N results within a group.

CUME_DIST (Transact-SQL)	LEAD (Transact-SQL)
FIRST_VALUE (Transact-SQL)	PERCENTILE_CONT (Transact-SQL)
LAG (Transact-SQL)	PERCENTILE_DISC (Transact-SQL)
LAST_VALUE (Transact-SQL)	PERCENT_RANK (Transact-SQL)
