CREATE TABLE "classification" (
  "driver" text,
  "constructor" text,
  "laps" real,
  "time_retired" text,
  "grid" real
);

Question: Where the grid is under 19, the time finished was logged as received outside assistance, what's the total number of laps?
SQL: SELECT COUNT("laps") FROM "classification" WHERE "time_retired"='received outside assistance' AND "grid"<19;
