Business Intelligence with Microsoft Power BI - with Material - Column from Examples - Merging Columns

The video tutorial explains how to merge multiple columns into one using Power Query. It demonstrates the use of 'Column from Examples' to concatenate columns with a delimiter, and discusses the creation of M functions in the backend. The tutorial provides examples of merging columns with different character selections and highlights the efficiency of using Power Query over manual methods. It concludes with a final example and encourages viewers to explore more functions.

What is the primary goal when merging columns in Power Query as discussed in the first section?

In the second section, what is a key step when Power Query does not understand the pattern for merging?

• Delete all existing columns

• Restart the Power Query application

• Manually adjust the M function

• Train Power Query by providing more examples

What is the role of the M function in Power Query as mentioned in the second section?

• It is used to import data

• It is a manual script written by the user

• It is automatically generated to perform operations

• It is used to export data

In the final section, what flexibility does Power Query offer when merging columns?

• It requires manual coding for each merge

• It allows for merging only numeric columns

• It can only merge columns with the same data type

• It supports various text manipulations and delimiters

What is the delimiter used in the final example of merging columns?
