Functions
There are various types of functions that you can use in expressions.
Topics:
Aggregate Functions
Aggregate functions perform operations on multiple values to create summary results.
The following list describes the aggregation rules that are available for columns and measure columns. The list also includes functions that you can use when creating calculated items for analyses.

Default — Applies the default aggregation rule as in the semantic model or by the original author of the analysis. Not available for calculated items in analyses.

Server Determined — Applies the aggregation rule that's determined by the Oracle Analytics (such as the rule that is defined in the semantic model). The aggregation is performed within Oracle Analytics for simple rules such as Sum, Min, and Max. Not available for measure columns in the Layout pane or for calculated items in analyses.

Sum — Calculates the sum obtained by adding up all values in the result set. Use this for items that have numeric values.

Min — Calculates the minimum value (lowest numeric value) of the rows in the result set. Use this for items that have numeric values.

Max — Calculates the maximum value (highest numeric value) of the rows in the result set. Use this for items that have numeric values.

Average — Calculates the average (mean) value of an item in the result set. Use this for items that have numeric values. Averages on tables and pivot tables are rounded to the nearest whole number.

First — In the result set, selects the first occurrence of the item for measures. For calculated items, selects the first member according to the display in the Selected list. Not available in the Edit Column Formula dialog box.

Last — In the result set, selects the last occurrence of the item. For calculated items, selects the last member according to the display in the Selected list. Not available in the Edit Column Formula dialog box.

Count — Calculates the number of rows in the result set that have a nonnull value for the item. The item is typically a column name, in which case the number of rows with nonnull values for that column are returned.

Count Distinct — Adds distinct processing to the Count function, which means that each distinct occurrence of the item is counted only once.

None — Applies no aggregation. Not available for calculated items in analyses.

ReportBased Total (when applicable) — If not selected, specifies that the Oracle Analytics should calculate the total based on the entire result set, before applying any filters to the measures. Not available in the Edit Column Formula dialog box or for calculated items in analyses. Only available for attribute columns.
