   You  can either use a CURSOR and FETCH only the first row, or   use LIMIT (non-standard).
   And you might  want  to  explicitly  ORDER  the  result  set,   otherwise   exchange   "FIRST"   with  "ONE-RANDOM"
in your   question.

SELECT * FROM cars ORDER BY <your pkey> LIMIT 1;

Without ORDER BY, there is no "first" record - any record could be 
returned.
