How to merge rows from 2 data tables without duplication without matching key

Question

I am using Excel PowerPivot. I have a database with all the records. In PowerPivot I have connected to the database and have added a query select * from table1. Now the problem is table1 is having huge data and daily I do data refresh in excel sheet from Data->Refresh and because not there are records in millions it is taking nearly 2 hours to fetch data. So to reduce the processing time I can add one more query to PowerPivot i.e select * from table1 where date - interval '30 day'. And daily I will do data refresh for this query which pulls data for last 30 days. So now I have 2 data models and in excel sheet I want to see the records from both the tables in PivotTable without duplication of rows. How can I achieve this?

Hi @Toral Patel,

To merge rows from two data tables without duplication without matching key in PowerPivot, you can use the "Append Queries" feature. First, create a connection to each table in PowerPivot. Then, go to the "Power Query Editor" and select the first table. From the "Combine" dropdown, select "Append Queries". In the "Append Queries" dialog, select the second table and click "OK". This will append the rows from the second table to the first table without creating duplicates. Finally, load the combined query into PowerPivot and create a PivotTable from it.
