AND Function

Returns true if both arguments evaluate 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 AND function returns a Boolean value, it can be used as a function or a conditional.

Anmerkung

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

and(finalScoreEnglish &gt;= 60, finalScoreMath &gt;=60)

Tipp

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:

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.

Transformation:

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

 Transformation Name New formula Single row formula AND(isActive, isInterested) 'phoneCall'

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

 Transformation Name New formula Single row formula OR(isActive, isInterested) 'sendEmail'

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

 Transformation Name New formula Single row formula AND(NOT(isActive),NOT(isInterested) '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 sendEmail IF(phoneCall == "TRUE", FALSE, sendEmail)

Results:

Customer
