CREATE TABLE table_4327 ("Heat Rank" FLOAT, "Lane" FLOAT, "Swimmer" CLOB, "Country" CLOB, "Time" FLOAT, "Overall Rank" CLOB)

I want to know the highest heat rank for overall rank of t63 and time less than 25.47
SELECT MAX("Heat Rank") FROM table_4327 WHERE "Overall Rank" = 't63' AND "Time" < '25.47'
SELECT MAX("Heat Rank") FROM "table_4327" WHERE "Overall Rank" = 't63' AND "Time" < '25.47'
