Computes the rolling list of values forward or backward of the current row within the specified column and returns an array of these values.

ROWNUMBER Function

Generates a new column containing the row number as sorted by the order parameter and optionally grouped by the group parameter.

SESSION Function

Generates a new session identifier based on a sorted column of timestamps and a specified rolling timeframe.

Description

COALESCE Function

Function returns the first non-missing value found in an array of columns.

RAND Function

The RAND function generates a random real number between 0 and 1. The function accepts an optional integer parameter, which causes the same set of random numbers to be generated with each job execution.

RANDBETWEEN Function

Generates a random integer between a low and a high number. Two inputs may be Integer or Decimal types, functions returning these types, or column references.

PI Function

The PI function generates the value of pi to 15 decimal places: 3.1415926535897932.

SOURCEROWNUMBER Function

Returns the row number of the current row as it appeared in the original source dataset before any steps had been applied.

IF Function

TheIFfunction allows you to build if/then/else conditional logic within your transforms.

CASE Function

TheCASEfunction allows you to perform multiple conditional tests on a set of expressions within a single statement. When a test evaluates to true, a corresponding output is generated. Outputs may be a literal or expression.

Ternary Operators

Ternary operators allow you to build if/then/else conditional logic within your transforms. Please use the IF function instead.

IPTOINT Function

Computes an integer value for a four-octet internet protocol (IP) address. Source value must be a valid IP address or a column reference to IP addresses.

IPFROMINT Function

Computes a four-octet internet protocol (IP) address from a 32-bit integer input.

RANGE Function

Computes an array of integers, from a beginning integer to an end (stop) integer, stepping by a third parameter.

HOST Function

Finds the host value from a valid URL. Input values must be of URL or String type and can be literals or column references.

DOMAIN Function

Finds the value for the domain from a valid URL. Input values must be of URL or String type.

SUBDOMAIN Function

Finds the value a subdomain value from a valid URL. Input values must be of URL or String type.

SUFFIX Function

Finds the suffix value after the domain from a valid URL. Input values must be of URL or String type.

URLPARAMS Function

Extracts the query parameters of a URL into an Object. The Object keys are the parameter's names, and its values are the parameter's values. Input values must be of URL or String type.
