good resources for data prepping in SQL before Power BI

[mikebi]

Hello,

When working on a large project I feel that there should be some data modelling ahead of Power Query in SQL.

As an example sometimes creating calculated fields, joins,  etc is easier and more efficient in SQL.

I also feel that data cam be filtered in SQL before PowerBI to reduce data load times.  As an example, let's say I only want to load 4 years of data.  It could be more efficient to create a view of 4 years of data vs bringing in all the data into Power Query and then filtereing.

Are there any resources on data prepping for PowerBI using SQL Server?

Thank You,

Michael

HI @mikebi,

I'd like to suggest you turn on the advanced option on the data connector to use sql statement to pre-processing of the result or customize the result tables.
