CREATE TABLE table_name_50 (entrant VARCHAR2, chassis VARCHAR2, points VARCHAR2, year VARCHAR2, engine VARCHAR2)

Who used Ford v8 and Jordan 191 after 1990 and got 8 points?
SELECT entrant FROM table_name_50 WHERE year > 1990 AND engine = "ford v8" AND points = 8 AND chassis = "jordan 191"
SELECT "entrant" FROM "table_name_50" WHERE "chassis" = "jordan 191" AND "engine" = "ford v8" AND "points" = 8 AND "year" > 1990
