Qlik Sense is a perfect combination of sophisticated AI, scalable multicloud architecture, associated analytics engine. It helps us to understand the input data by making the required changes. It could be termed as a benchmark for a new generation of analytics. In this tutorial, we discuss different types of Qlik Sense Operators that are helpful while working on Qlik Sense.
The architecture of Qlik Sense is designed in a way to provide a secure, scalable and easily manageable work environment to every user.
What are Qlik Sense Operators
Visualization is analyzing the developed graphs based on input data. Qlik Sense helps in linking and integrating data from varied data sources. The integrated data is then displayed with the help of high–quality visuals that are highly responsive to any changes made in data.
As per the BARC’s BI Survey 2019, Qlik was ranked no.1 “data visualization” tool as it exceeded in all the fields such as customer experience, performance satisfaction, business value, and data analysis.
Operators are pre–defined functions that are used to evaluate an expression.
An expression is a combination of operands and operators which when solve give the desired output.
Now, let us understand Expression, Operator, and Operand with the help of an example
a = 5 + 6 + 1
Operands: 5, 6, 1
Operator: +
Expression: 5 + 6 + 1
Resulting Value: 12
The various type of Qlik Sense operators are as follows:
i) Qlik Sense Bit Operators
Process of evaluation: Bit by Bit
Return type: 32bit signed integer value
Exception: The conversion of simple numeric value into 32bit value occurs only on numerical values, otherwise it returns NULL
Various Bit Operators used in Qlik Sense Script
1) Bitnot Operator
Process of Evaluation: Bit by Bit
Input: Only 1 argument
Alternative name: Bit inverse operator
Returns: Logical inverse of an Operand
Example: bitnot 17 return –18
2) Bitand Operator
Process of Evaluation: Bit by Bit
Input: Takes twoargument
Alternative name: “Bit and” operator
Returns: Logical and of an Operands
Example: 17 bitand 7 returns 1
3) Bitor Operator
Process of Evaluation: Bit by Bit
Alternative name: “Bit or” operator
Returns: Logical OR of an Operand
Example: 17 bitor 7 return 23
4) Bitxor Operator
Process of Evaluation: Bit by Bit
Alternative name: “Bit exclusive or” operator
Returns: Logical exclusive OR of an Operand
Example: bitnot 17 return –18
5) >> Operator
Process of Evaluation: Bit by Bit
Alternative name: “Bit Right Shift” operator
Returns: Value where first Operand is shifted towards Right
Example: 8>> 2 return 2
6) << Operator
Process of Evaluation: Bit by Bit
Alternative name: “Bit Left Shift” operator
Returns: Value of first Operand is shifted towards Left
Example: 8<< 2 return 32

ii) Qlik Sense Logical Operators
Process of Evaluation: Evaluate the operand Logically
Return Type: Boolean Value; True or False
Various types of Qlik Sense Logical Operators
1) Not Operator
Type of Operator: Unary Operator
Alternative Name: Logical Inverse Operator
Return: If the input operand is True “NOT” would return False
Example: !1 = 0
2) And Operator
Alternative Name: “Logical and” Operator
Return: If both the operands are True “And” would return True, if any one input statement is False and would return False
Example: 1 &&(And) 1 returns 1(True)
1 &&(And) return 0(False)
3) Or Operator
Alternative Name: “Logical or” Operator
Return: If one of the operands is False and one is True, “Or” would return True
Example: 1 (Or) 0 returns 1(True)
4) Xor Operator
Alternative Name: “Logical exclusive or” operator
Return: If both the operand is True “Xor” would return False. It is a difference from logical or operator
Example: !(1  1) return 0

iii) Qlik Sense Numeric Operators
Type of Operator: Unary or Bitwise Operator
Process of Evaluation: It is used to perform Arithmetic calculations for both the operands
Various types of Qlik Sense Numeric Operator
1) ‘+’ Operator
Type of Operator: Unary Operator and Binary Operator
Alternative Name: “Addition” Operator
Return: While functioning as “Unary Operator”, serve as a positive sign (+) for any number. While functioning as “Binary Operator” it returns the sum of two operands.
Example: 1. 1 + 1 returns 2

 +12 means number is positive
2) ‘‘ Operator
Type of Operator: Unary and Binary Operator
Alternative Name: “Subtraction” Operator
Return: While functioning as “Unary Operator”, serve as a negative sign () for any number. While functioning as “Binary Operator” it returns the difference of two operands.
Example:1. 3 – 2 returns 1

 1 represent “1” as a negative number
3) ‘*’ Operator
Type of Operator: Binary Operator
Alternative Name: “Multiplication” Operator
Return: It returns the product of two operands between which an operator is applied
Example: 5 * 5 returns 25
4) ‘/’ Operator
Type of Operator: Binary Operator
Alternative Name: “Division” operator
Return: It returns the ratio of two operands between which it is applied
Example: 8 / 2 returns 4
iv) Qlik Sense Relational Operator
Process of Evaluation: Evaluate Numerically
Return Type: Boolean Value; True or False
Various types of Qlik Sense Relational Operators
1) ‘<’ Operator
Alternative Name: “Less than” Operator
Return: It returns True if the operand1 (on the Left) is lesser than the value of operand 2 (on the right).
It returns False if the operand1 (on the Left) is greater than the value of operand 2 (on the right)
Example: 1. 5 < 4 returns “False”

 3 < 4 returns “True”
2) ‘>‘ Operator
Alternative Name: “Greater than” Operator
Return: It returns True if the operand1 (on the Left) is greater than the value of operand 2(on the right).
It returns False if the operand1 (on the Left) is lesser than the value of operand 2(on the right).
Example:1. 3 > 2 return “True”

 3 < 2 return “False”
3) ‘<=’ Operator
Alternative Name: “Less than equal to” Operator
Return: It returns True if the operand1 (on the Left) is “less than equal to” the value of operand 2(on the right).
It returns False if the operand1 (on the Left) is “greater than equal to” the value of operand 2(on the right)
Example: 5 <= 5 returns “True”
4) ‘>=’ Operator
Alternative Name: “Greater than equal to” Operator
Return: It returns True if the operand1 (on the Left) is “greater than equal to “the value of operand 2(on the right).
It returns False if the operand1 (on the Left) is “lesser than equal to” the value of operand 2(on the right).
Example: 6 >= 7 returns “False”
5) ‘=‘ Operator
Alternative Name: “Equals” Operator
Return: It returns True if the operand on “left” and “right” both have the same value, otherwise it returns False
Example:1. 3 = 2 returns False

 2 =2 return True
6) ‘<>’ Operator
Alternative Name: “Not equivalent to” Operator
Return: It evaluates the two operands and returns a result such that Operand 1 is not equal to Operand 2
Example: Weight <> 90; This would return the weight of all humans not equal to 90 Kg
7) Precedes Operator
Alternative Name: “String Comparison” operator
Return: It returns the True if the operand on “Left” has a value lesser than operand on “Right”; otherwise it returns False
Example: ‘4’ precedes ‘ 5’ return False because 4 is “greater than” ‘ ‘ which is before 5
v) Qlik String Operator
String Operator is used to performing an operation on alphabets or words.
Various Qlik Sense String Operators are
1) ‘&’ Operator
Alternative Name: “String Concatenation” Operator
Return: It joined the “two” strings and return “concatenated” string
Example: “Dhruv” & “ Trehan” returns Dhruv Trehan
2) Like Operator
It is basically a String Comparison with Wildcard Character.
Return: It returns “True” if a String of Operand 1 is matched with String of Operand 2; otherwise it returns False
Example: 1. ‘def’ like ‘d*’ returns True

 ‘fgh’ like ‘f??gh’ returns False
In this blog, we learned about:
 Qlik Sense: A “data visualization” tool for analyzing the input data with the help of a developed graph. It can integrate and link data from varied data sources easily and effectively.
 Operators: These are pre–defined functions which are used to solve an expression
 We even learned about a different type of operators and its types such as:
 Bit Operator: It evaluates the value “Bit by Bit” and it performs operations at “Binary Level”
 Logical Operator: It returns “True” and “False” depending upon the input
 Numeric Operator: It performs “Arithmetic” Calculation between two operands
 Relational Operator: It returns “True” and “False” depending upon the input
 String Operator: It used to perform String operation such as concatenation on words and characters
