CREATE TABLE table_name_84 (constructor VARCHAR2, time_retired VARCHAR2, laps VARCHAR2, grid VARCHAR2)

When grid is less than 7, laps are greater than 17, and time/retired is + 1:35.6, who is the constructor?
SELECT constructor FROM table_name_84 WHERE laps > 17 AND grid < 7 AND time_retired = "+ 1:35.6"
SELECT "constructor" FROM "table_name_84" WHERE "+ 1:35.6" = "time_retired" AND "grid" < 7 AND "laps" > 17
