There are a total of 2 doctors.

You can use concat method to append and group by and count function to get number for each occupation
SELECT "There are a total of ", count(OCCUPATION), concat(lower(occupation),"s.") FROM OCCUPATIONS GROUP BY OCCUPATION ORDER BY count(OCCUPATION), OCCUPATION ASC

Just to clarify. There is sucha function and it's SELECT. You can print things like this:
SELECT "Hello world" as "";
or
SELECT "Hello world" as ""\G;
There is no way to remove the : prefix in the second case.
