Returns true if the first argument is not equal to the second argument. Equivalent to the <> or != operator.
• Each argument can be a literal String, Integer or Decimal number, a function, or a column reference.

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

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

notequal(myValue, checkSum)

Output:
Returns true  if the value in the myValue column does not equal the value in the checkSum column.

## Syntax and Arguments

notequal(value1, value2)

ArgumentRequired?Data TypeDescription
value1YstringThe first value. This value can be a String, a number, a function, or a column reference.
value2YstringThe second value. This value can be a String, a number, a function, or a column reference.

### value1, value2

Names of the columns, expressions, or literals to compare.

• Missing values generate missing results.

Usage Notes:

Required?Data TypeExample Value
YesColumn reference, function, or numeric or String valuemyColumn

## Examples

### Example - Basic Equal and Notequal Functions

This example demonstrate the following comparison functions.

In this example, the dataset contains current measurements of the sides of rectangular areas next to the size of those areas as previously reported. Using these functions, you can perform some light analysis of the data.

6635

1515200

12670

Transformation:

In the first test, you are determining if the four-sided area is a square, based on a comparison of the measured values for sideA and sideB:

Transformation Name New formula Single row formula EQUAL(sideA, sideB) 'isSquare'

Next, you can use the reported sides to calculate the area of the shape and compare it to the area previously reported:

Transformation Name New formula Single row formula NOTEQUAL(sideA * sideB, reportedArea) 'isValidData'

You can also compute if the reportedArea can be divided into even square units:

Transformation Name New formula Single row formula ISEVEN(reportedArea) 'isReportedAreaEven'

You can test if either measured side is an odd number of units:

Transformation Name New formula Single row formula IF((ISODD(sideA) == true) OR (ISODD(sideB) == true),TRUE,FALSE) 'isSideOdd'
