Hello,
I've got a question that I haven't been able to figure out on my own, Using PBI Desktop, asfter selecting a data source, you're given the option in Advanced Options to write an SQL statement to precisely select the columns/parameters you'd like to have load in your dataset. Lets assume I do the following:
SELCECT COLUMN-A, COLUMN-B
FROM TABLE-1
So I'll only get 2 columns from my 100 column table.
Let's say that I did NOT write this statement and opted to load the entire report. Now I go to Edit Queries and Remove all Columns except COLUMN-A, COLUMN-B using the PBI UI.
- Did I just accomplish the same thing?
- If I choose to Remove Columns, will the removed columns still be queried, but just not displayed in the dataset?
- If so, what is the equivalent to a WHERE statement in Query Editor? Some sort of DAX measure?
The end goal here is to limit load times. Our connection to a certain Oracle DB is very slow and I'm trying to make my dataset as lean as possible.
