Question

I do not know where to start with this one, not sure if it is possible.

I have multiple columns. To simplify I will minimize my actual setup since I can describe it fine with two tables

Say I have two tables called thumbs & thumb_clicks.
What I need to do is select all of the most clicked thumbs and order by most clicked. My problem however is, what if only 2 thumbs were clicked and I need to display 100 on the page.

What I would like to accomplish is select thumbs by most clicked, if results are less than 100, select the most relevant thumbs to fill the rest of the spots.

I am looking to be pointed in the right direction for this if possible!
Appreciate it!

What you looking for is UNION clause that lets you ‘merge’ results from two (or more) queries.
