Working with data sources in M

To effectively work with different data sources, you need a good grasp of M’s capabilities for more dynamic and flexible data transformations. It’s essential to understand how M can be used to customize and parameterize data source connections. In short, this will help you to enhance reusability and facilitate easy adjustments to queries without manual code modification, thus saving you time later down the line.

In the following sections, you will learn about how to actually go about creating parameters with the help of examples for you to follow along and implement in your own environment.

Creating parameters and variables

Parameters and variables can be used for a number of different uses in M queries. One of which is to allow you to decouple your data source details from your M query, making it easy to switch between different sources. By defining parameters for key attributes such as file paths or server addresses, you can change...
