CREATE TABLE table_40923 ("From" FLOAT, "Goal" CLOB, "Round 1" CLOB, "Round 2" CLOB, "Round 3" CLOB, "Round 4" CLOB, "Round 5" CLOB, "Round 6+" CLOB)

What is Round 2 when Round 4 is Double and Round 3 is Single?
SELECT "Round 2" FROM table_40923 WHERE "Round 4" = 'double' AND "Round 3" = 'single'
SELECT "Round 2" FROM "table_40923" WHERE "Round 3" = 'single' AND "Round 4" = 'double'
