QlikView Functions – Your Ultimate Analytics Companion!

QlikView functions are used to perform calculations and operations on data within your data model. QlikView has a wide range of built-in functions that can be used to perform tasks such as aggregation, filtering, and data manipulation.

Here are some examples of common QlikView functions:

1. Aggregation functions: These functions are used to perform calculations on data, such as summing, averaging, or counting data points. Examples include SUM(), AVG(), and COUNT().
2. Filtering functions: These functions are used to select specific data points based on certain criteria. Examples include IF(), WHERE(), and MATCH().
3. Data manipulation functions: These functions are used to transform or manipulate data in various ways. Examples include DATE(), TIME(), and CONCATENATE().
4. Statistical functions: These functions are used to perform statistical calculations on data, such as calculating standard deviation or correlation. Examples include STDEV(), CORR(), and MEDIAN().

To use a function in QlikView, you can type it into the script editor or select it from the function library. You can then specify the arguments for the function, such as the data field or expression to be used in the calculation.

Some of the key features of QlikView functions include:

• Built-in functions: QlikView provides a wide range of built-in functions, such as mathematical functions (e.g. SUM(), COUNT(), AVG()), string functions (e.g. LEFT(), LEN()), date and time functions (e.g. DATE(), MONTH(), NOW()), and aggregate functions (e.g. COUNTD(), MIN()).
• User-defined functions: Users can create their own custom functions using QlikView’s scripting language.
• Function wizard: The function wizard in QlikView walks users through the process of creating and utilising functions.
• Function chaining: Functions can be used in combination with other functions, or with operators, to perform more complex calculations and operations on the data.
• Function parameters: Functions can take one or more parameters, which can be used to customize the function’s behavior or output.
• Function nesting: Functions can be nested within other functions, allowing for the creation of highly complex calculations and operations.
• Function documentation: QlikView provides documentation for all built-in functions, which includes a description of the function, the syntax and examples of how to use the function.

Overall, the QlikView function feature is an important tool for performing complex calculations and operations on data, quickly and easily. It allows users to use built-in functions or create custom ones, with the help of a function wizard. It also allows function chaining, function parameters and function nesting, making the data analysis more efficient and accurate.
