Power bi programming language m.
Just like sql server management studio which obscures the t sql generated by menu selections and actions the power bi designer is based upon the power query formula language informally know as m.
Microsoft power bi supports two different languages m language and dax data analysis expression that can be used to filter manage and visualize data.
Microsoft power query provides a powerful data import experience that encompasses many features.
It is a functional case sensitive language similar to f.
Create a query with query editor to create an advanced query you use the query editor.
Reduce development time by taking advantage of a wide variety of automation options.
Push data into a power bi dataset refresh your data automatically auto scale azure resources automate your application lifecycle management alm and more with power bi rest apis.
But if you call it that no one will know what you are talking about.

A mashup query is composed of variables expressions and values encapsulated by a let expression.
M will likely be the first language that new users actually use although it is unlikely that they are aware of the fact that they are using it.
This approach might better suit those who come from a more technical background.
Every time you create a query in power query whether in excel or power bi power query generates a functional script in m.
M is a functional language and it is important to know functions of it.
M can be considered as a query formula language and it can be used in the power bi query editor in order to prepare data before it can be loaded into the power bi model.
Automate your bi solution.
Its name is power query formula language.
The m language is a functional language for which the classical loop constructions of other languages are foreign.
The power query formula language informally known as m is a powerful mashup query language optimized for building queries that mashup data.
