CREATE TABLE table_76243 ("Name" TEXT, "Gain" FLOAT, "Loss" FLOAT, "Long" FLOAT, "Avg/G" FLOAT)

When the Gain is 29, and the average per game is 2, and the player lost less than 390 yards, what's the sum of the Long yards?
SELECT SUM("Long") FROM table_76243 WHERE "Loss" < '390' AND "Avg/G" = '2' AND "Gain" > '29'
SELECT SUM("Long") FROM "table_76243" WHERE "Avg/G" = '2' AND "Gain" > '29' AND "Loss" < '390'
