The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

What you are trying to do might better be accomplished in Power Query. For example, you should be able to paste your SQL code into a Power Query query and import the table exactly as you want. Failing that, there are functions like NATURALINNERJOIN in DAX but it would be more useful to present your source data and expected output versus SQL code.
