CREATE TABLE table_49478 ("Peak" TEXT, "Location" TEXT, "Height  ( m ) " FLOAT, "Prominence  ( m ) " FLOAT, "Col  ( m ) " FLOAT, "Parent" TEXT)

What is the maximum Col (m) when 3,046 is the Prominence (m)?
SELECT MAX("Col (m)") FROM table_49478 WHERE "Prominence (m)" = '3,046'
SELECT MAX("Col (m)") FROM "table_49478" WHERE "Prominence (m)" = '3,046'
