Analytic functions compute an aggregate value based on a group of rows. They differ fromaggregate functions in that they return multiple rows for each group. The groupof rows is called a window and is defined bythe analytic_clause. For each row, a sliding window of rows is defined.The wind...

One of the most hailed extensions brought to SQL in recent years has been these functions that Oracle calls analytic functions, DB2 calls OLAP functions, and SQL Server 2005 calls ranking functions--but which MySQL, so far, still lacks. The good news is that they can be (relatively) easily...
The financial functions include interest rate calculations, depreciation, and payment schedules, similar to those provided in spreadsheets. For example, theFPMTSCHEDfunction calculates a payment schedule (principal plus interest) for paying off a series of fixed-rate installment loans over a specified ...
SQL Server 支持以下分析函数: 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) ...
These views use OLAP_TABLE functions to return information about logical standard form objects within analytic workspaces. For example, you could query an Active Catalog view to obtain information about the dimensionality of a workspace cube. The Active Catalog view names have the prefix ALL_OLAP2_...
