Hi all,
I am having all kinds of problems with an ODBC connection to Power BI Desktop. I'm not an IT or Database expert, although I'm ok with using Power BI when the data is actually in, it's just connecting is the problem.
I had the error of "References other Queries" that is spoken of in the link
http://www.excelguru.ca/blog/2015/03/11/power-query-errors-please-rebuild-this-data-combination/
I now seem to have fixed that problem (for now) by creating a duplicate version of table then on the orignal table querying to the duplicated table. The problem I have is the size of the table, because there are over 5 million rows, and I have now duplicated the table. When I go to apply changes or refresh the data. The Apply Query Changes box wants to update all rows therefore it goes through 5 million rows on the original table and 5 million on the duplicated table. Is there anything I can do to stop it updating all 10 million rows it takes ages to update all of these rows, maybe just by updating one of the tables as its a duplicate?
Sorry I feel like this is something simple that I should be able to figure out but cannot seem to find something. It's frustrating whenever I make changes and then have to wait for 10 millions rows to update only to find out my changes weren't quite right, and need more changes!
Thanks in advance. Any help would be much appreciated
