Make 1st row from underlying query the default of a Select Component

Newbie here. My dashboard has a Select Component driven by an SQL query. All the examples I've seen so far hard code a default value for the parameter driven by the Select component. My data is constantly changing so this won't work for me.

So I want to make the first row in the result set returned by the Select Component query the default when the dashboard comes up initially.


How can I do this ? Thanks in advance
