Logical Operators

Logical operators (and, or, not) enable you to logically combine multiple expressions to evaluate a larger, more complex expression whose output is true or false.

(left-hand side) (operator) (right-hand side)

These evaluations result in a Boolean output. The following operators are supported:

Operator Name	Symbol	Example Expression	Output	Notes
and	&&	`((1 == 1) && (2 == 2))`	true
		`((1 == 1) && (2 == 3))`	false
or	\|\|	`((1 == 1) \|\| (2 == 2))`	true	Exclusive or (xor) is not supported.
		`((1 == 2) \|\| (2 == 3))`	false
not	!	`!(1 == 1)`	false
		`!(1 == 2)`	true

The above examples apply to integer values only. Below, you can review how the comparison operators apply to different data types.

Usage

Logical operators are used to perform evaluations of expressions covering a variety of data types. Typically, they are applied in evaluations of values or rows.

Example data:

X	Y
true	true
true	false
false	true
false	false

Transforms:

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	(X && Y)
Parameter: New column name	'col_and'

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	(X \|\| Y)
Parameter: New column name	'col_or'

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	!(or)
Parameter: New column name	'col_not_and'

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	!(or)
Parameter: New column name	'col_not_or'

Results:

Your output looks like the following:

X	Y	col_and	col_or	col_not_and	col_not_or
true	true	true	true	false	false
true	false	false	true	true	false
false	true	false	true	true	false
false	false	false	false	true	true

Notes

Integer/Decimal

Transformation Name	`Edit column with formula`
Parameter: Columns	InRange
Parameter: Formula	((Input >= 10) && (Input <= 90))

Set the value of the InRange column to true if the value of the Input column is between 10 and 90, inclusive.
Otherwise, InRange column is false.

Datetime

Transformation Name	`Filter rows`
Parameter: Condition	Custom formula
Parameter: Type of formula	Custom single
Parameter: Condition	((Date >= DATE(2014, 01, 01)) && (Date <= DATE(2014, 12, 31))
Parameter: Action	Delete matching rows

Delete all rows in which the Date value falls somewhere in 2014.

String

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	((LEFT(USStates,1) == "A") && (RIGHT(USStates,1) == "A"))

For U.S. State names, the generated column contains true for the following values:

Alabama
Alaska
Arizona

For all other values, the generated value is false.

See LEFT Function.
See RIGHT Function.

Notes

Integer/Decimal

Transformation Name	`Edit column with formula`
Parameter: Columns	BigOrder
Parameter: Formula	((Total > 1000000) \|\| (Qty > 1000))

In the BigOrder column, set the value to true if the value of Total is more than 1,000,000 or the value of Qty is more than 1000.
Otherwise, the value is false.

Datetime

Transformation Name	`Filter rows`
Parameter: Condition	Custom formula
Parameter: Type of formula	Custom single
Parameter: Condition	((Date <= DATE(1950, 01, 01)) \|\| (Date >= DATE(2050, 12, 31))
Parameter: Action	Delete matching rows

Delete all rows in the dataset where the Date value is earlier than 01/01/1950 or later than 12/31/2050.

String

Transformation Name	`New formula`
Parameter: Formula type	Single row formula
Parameter: Formula	((Brand == 'subaru') \|\| ('Color' == 'green'))
Parameter: New column name	'good_car'

Generate the new good_car column containing true if the Brand is subaru or the Color is green.
Otherwise, the good_car value is false.

Parameter: Condition	!((sqft < 1300) && (bath < 2) && (bed < 2.5))
Parameter: Action	Keep matching rows

Keep all rows for houses that do not meet any of these criteria:

smaller than 1300 square feet,
less than 2 bathrooms,
less than 2.5 bedrooms.

Datetime

Transformation Name	`Filter rows`
Parameter: Condition	Custom formula
Parameter: Type of formula	Custom single
Parameter: Condition	!(YEAR(Date) == '2016')
Parameter: Action	Keep matching rows

Keep all rows in the dataset where the year of the Date value is not 2016.

String

Transformation Name	`Filter rows`
Parameter: Condition	Custom formula
Parameter: Type of formula	Custom single
Parameter: Condition	!(status == 'Keep_It')
Parameter: Action	Delete matching rows
