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 NameSymbolExample ExpressionOutputNotes
and&&

((1 == 1) && (2 == 2))

true 
  

((1 == 1) && (2 == 3))

false 
or||

((1 == 1) || (2 == 2))

trueExclusive 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:

XY
truetrue
truefalse
falsetrue
falsefalse

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:

XYcol_andcol_orcol_not_andcol_not_or
truetruetruetruefalsefalse
truefalsefalsetruetruefalse
falsetruefalsetruetruefalse
falsefalsefalsefalsetruetrue

Column TypeExample TransformOutputNotes
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.

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.
