Loop through sql server table to read a set of data in each iteration and do unpivoting

There is a Query Parameter feature allows you to dynamically change the excel tables based on the sequence you selected. However, I am not sure whether you can bring the parameter together with Pbi dataset back to SQL. You may try export power bi dataset to SQL afterwards: Exporting Power BI Data to SQL Server (biinsight.com).

Please refer to my example for using parameter on excel files:

1.  Connect to the folder that has all excel files, OK=>Transform.

2. Add an index column from 1, right click the index column=>add as new query.

3. Create the a parameter based on the new query.

4. Once parameter is created, set it as filter to the index column. 

5. The final step is to expand the excel table, Close and Apply.

You then can dynamically change the displayed table data using parameter.
