OR Function

Returns true if either argument evaluates to true. Equivalent to the || operator.

Each argument can be a literal Boolean, a function returning a Boolean, or a reference to a column containing Boolean values.

Since the function returns a Boolean value, it can be used as a function or a conditional.

Nota

Within an expression, you might choose to use the corresponding operator, instead of this function. For more information, see Logical Operators.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.

Basic Usage

or(daysBillOverdue > 90, violationsCount > 2)

Output: If the value in the daysBillOverdue column is greater than 90 or the value in violationsCount column is greater than 2, then the returned value is true. Otherwise, the value is false.

Syntax and Arguments

or(value1, value2)

Argument	Required?	Data Type	Description
value1	Y	string	The first value must be a Boolean literal, column reference, or expression that evaluates to `true` or `false`.
value2	Y	string	The first value must be a Boolean literal, column reference, or expression that evaluates to`true`or`false`.

For more information on syntax standards, see Language Documentation Syntax Notes.

value1, value2

Expressions, column references or literals to compare as Boolean values.

Missing or mismatched values generate missing results.

Usage Notes:

Required?	Data Type	Example Value
Yes	Function or column reference returning a Boolean value or Boolean literal	myHeight > 2.00

Example - Logical Functions

This example demonstrate the AND, OR, and NOT logical functions.

In this example, the dataset contains results from survey data on two questions about customers. The yes/no answers to each question determine if the customer is 1) still active, and 2) interested in a new offering.

Functions:

Item	Description
AND Function	Returns `true` if both arguments evaluate to `true`. Equivalent to the `&&` operator.
OR Function	Returns `true` if either argument evaluates to `true`. Equivalent to the `\|\|` operator.
NOT Function	Returns `true` if the argument evaluates to `false`, and vice-versa. Equivalent to the `!` operator.

Source:

Customer	isActive	isInterested
CustA	Y	Y
CustB	Y	N
CustC	N	Y
CustD	N	N

Transformation:

Customers that are both active and interested should receive a phone call:

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	AND(isActive, isInterested)
Parameter: New column name	'phoneCall'

Customers that are either active or interested should receive an email:

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	OR(isActive, isInterested)
Parameter: New column name	'sendEmail'

Customers that are neither active or interested should be dropped from consideration for the offering:

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	AND(NOT(isActive),NOT(isInterested)
Parameter: New column name	'dropCust'

A savvy marketer might decide that if a customer receives a phone call, that customer should not be bothered with an email, as well:

Transformation Name	`Edit column with formula`
Parameter: Columns	sendEmail
Parameter: Formula	IF(phoneCall == "TRUE", FALSE, sendEmail)

Results:

Customer	isActive	isInterested	dropCust	sendEmail	phoneCall
CustA	Y	Y	FALSE	FALSE	TRUE
CustB	Y	N	FALSE	TRUE	FALSE
CustC	N	Y	FALSE	TRUE	FALSE
CustD	N	N	TRUE	FALSE	FALSE
