CREATE TABLE table_name_69 (grid VARCHAR, laps VARCHAR, time_retired VARCHAR)

When the laps driven were under 9 and the time/retired recorded was engine, what's the total number of grid values?
SELECT COUNT(grid) FROM table_name_69 WHERE laps < 9 AND time_retired = "engine"
SELECT COUNT("grid") FROM "table_name_69" WHERE "engine" = "time_retired" AND "laps" < 9
