I’m trying to find rows where the first character is not a digit. I have this:

SELECT DISTINCT(action) FROM actions 
WHERE qkey = 140 AND action NOT REGEXP '^[:digit:]$';

    Your current regex will match values consisting of exactly one digit, not the first character only. Just remove the $ from the end of it, that means “end of value”. It’ll only check the first character unless you tell it to check more.

    ^[:digit:] will work, that means “start of the value, followed by one digit”.
