CREATE TABLE table_name_18 (width INT, frame_size VARCHAR, height VARCHAR)

What is the smallest width for a frame size of 5k and a height shorter than 2700?
SELECT MIN(width) FROM table_name_18 WHERE frame_size = "5k" AND height < 2700
SELECT MIN("width") FROM "table_name_18" WHERE "5k" = "frame_size" AND "height" < 2700
