CREATE TABLE table_name_91 (rank__night_ NUMBER, episode VARCHAR2, rating VARCHAR2)

What is the lowest nightly rank for an episode after episode 1 with a rating/share of 2.6/8?
SELECT MIN(rank__night_) FROM table_name_91 WHERE rating / SHARE(18 - 49) = 2.6 / 8 AND episode > 1
SELECT MIN("rank__night_") FROM "table_name_91" WHERE "episode" > 1 AND "rating" / NULLIF(SHARE(-31), 0) = 2.6 / NULLIF(8, 0)
