Overview of built-in formula functions

Incorta provides the ability to create new formula columns in the business schema view or within an insight on a dashboard using a comprehensive library of formula functions.

Here is a list of supported functions when creating a new formula:

Group	Description
Aggregation Functions	Summarize the contents of a column of data
Boolean Functions	Evaluate one or more expressions and return a boolean value
Conditional Statements	Evaluate and return the results of an expression depending on the result of evaluating a boolean expression
Conversion Functions	Converts values from one type to another
Filter Functions	These functions are used to filter data to those items before or after a specified date. It is also possible to filter the data in groups
Miscellaneous Functions	Various functions for finding values in table hierarchies, setting schema refresh interval and determining the row number in a query
Arithmetic Functions	Perform math operations on values
Date Functions	Adjust values of type date or timestamp
String Functions	Convert, truncate and search within text strings

How to Read Formula Function Reference Entries

Formula Function reference entries contain sections:

• Example(s) : includes a verbal description of a problem followed by how the solution looks in Incorta
• Syntax : the function prototype
• Notes : description of operation, context, details to pay attention to, limitations

Typefaces

The reference entries use typefaces in the following way:

Format	Meaning	Example
italic	variable	var or $var
bold	constant	true
fixed	code phrase	FindMedia(op_count,location)

Expressions

Formula functions take expressions as well as literals as arguments. For example, a column called x might contain strings which are actually numbers: “45.6”, “77.12”, “45.91”, … To find the average of the values in that column requires the strings be converted to numeric scalars. The formula function double does this. You could then write average(double(x)). In this case, an expression is passed to average.

Reference entries describe expressions using the expr keyword. For example, double expr means “expression evaluating to double”. More generally, <type> expr if more than one Incorta type can be passed as an argument. Square brackets [] indicate an Array of values such as double[] expr.

Incorta Types

Incorta types have the same characteristics as the Java types. They are:

• string — series of characters
• date — contains month, day and year
• timestamp — contains month, day, year and time
• int — 32 bit signed integer type
• long — 64 bit signed integer type
• double — 64 bit floating point type
