QlikView Operators – The Building Blocks of Dynamic Data Modeling

In QlikView, operators are symbols that are used to perform operations on values or variables. QlikView supports a variety of operators, including arithmetic operators, logical operators, and string operators.

Here are some examples of familiar QlikView operators:

• Arithmetic operators: These operators perform arithmetic calculations, such as addition, subtraction, multiplication, and division. For example:

5 + 6 // Addition 10 – 3 // Subtraction 4 * 2 // Multiplication 20 / 5 // Division

• Logical operators: These operators perform logical comparisons, such as equal to, not identical to, greater than, and less than. For example:

5 = 5 // Equal to 5 <> 6 // Not equal to 5 > 3 // Greater than 5 < 7 // Less than

• String operators: These operators perform operations on strings, such as concatenation and comparison. For example:

‘Hello ‘ & ‘world’ // Concatenation ‘Hello’ = ‘world’ // Comparison

You can use operators in QlikView to create expressions and calculations that manipulate data and perform advanced analysis. You can also use operators in conditions and filters to control the data which has been displayed in your visualizations.

Some of the key features of QlikView operators include:

• Mathematical operators: Users can use mathematical operators, such as addition (+), subtraction (-), multiplication (*), and division (/), to perform mathematical calculations on the data.
• Logical operators: Users can use logical operators, such as AND, OR, NOT, and XOR, to perform logical operations on the data.
• Comparison operators: Users can use comparison operators, such as equal to (=), not equal to (<>), greater than (>), and less than (<), to compare data values.
• Aggregate functions: Users can use aggregate functions, such as SUM(), COUNT(), AVG(), and MIN(), to calculate summary statistics for the data.
• Conditional statements: Users can use conditional statements, such as IF() and CASE(), to perform different calculations or operations based on certain conditions.
• Date and time functions: Users can use date and time functions, such as DATE(), MONTH(), and NOW(), to perform calculations on date and time data.
• Data transformation: Users can use operators to transform the data from one format to another, such as converting dates to a string format, or to perform data normalization.
• Scripting: Users can use operators in scripting to perform advanced calculations and operations on the data.

Overall, the QlikView operator feature is an important tool for performing mathematical calculations and logical operations on data, which can help users to uncover insights and patterns in the data. Users can use operators to perform advanced calculations, to compare data values, to calculate summary statistics, and to perform data transformation.
