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...

Analytic functions have been part of Oracle for a very long time now – ever since 8i back in 1999. Analytic functions are an ANSI/ISO standard, and so you’ll find that they are similarly-implemented across a number of compliant databases. (This SQL Server article on “window functio...
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 ...
You can use data in Excel workbooks, PowerPivot datasets, SQL databases, and “big datasets” using our built-in connection to Apache Spark clusters. Explore data visually, use feature selection, clustering and principal components, transform data with binning, re-scaling and missing value handling...
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_...
