ROWNUMBER Function	Generates a new column containing the row number as sorted by the `order` parameter and optionally grouped by the `group` parameter. See ROWNUMBER Function.
SESSION Function	Generates a new session identifier based on a sorted column of timestamps and a specified rolling timeframe. See SESSION Function.

Other Functions

Item	Description
COALESCE Function	Function returns the first non-missing value found in an array of columns. See COALESCE Function.
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. See RAND Function.
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. See RANDBETWEEN Function.
PI Function	The `PI` function generates the value of pi to 15 decimal places: 3.1415926535897932. See PI Function.
SOURCEROWNUMBER Function	Returns the row number of the current row as it appeared in the original source dataset before any steps had been applied. See SOURCEROWNUMBER Function.
IF Function	The `IF` function allows you to build if/then/else conditional logic within your transforms. See IF Function.
CASE Function	The `CASE` function 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. See CASE Function.
Ternary Operators	Ternary operators allow you to build if/then/else conditional logic within your transforms. Please use the `IF` function instead. See Ternary Operators.
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. See IPTOINT Function.
IPFROMINT Function	Computes a four-octet internet protocol (IP) address from a 32-bit integer input. See IPFROMINT Function.
RANGE Function	Computes an array of integers, from a beginning integer to an end (stop) integer, stepping by a third parameter. See RANGE Function.
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. See HOST Function.
DOMAIN Function	Finds the value for the domain from a valid URL. Input values must be of URL or String type. See DOMAIN Function.
SUBDOMAIN Function	Finds the value a subdomain value from a valid URL. Input values must be of URL or String type. See SUBDOMAIN Function.
SUFFIX Function	Finds the suffix value after the domain from a valid URL. Input values must be of URL or String type. See SUFFIX Function.
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. See URLPARAMS Function.
