CREATE TABLE table_203_102 (id NUMBER, "event" CLOB, "performance" CLOB, "athlete" CLOB, "nation" CLOB, "place" CLOB, "date" CLOB)

is the best time for the 100 m more or less than the time for the 110 m hurdles ?
SELECT (SELECT "performance" FROM table_203_102 WHERE "event" = '100 m') > (SELECT "performance" FROM table_203_102 WHERE "event" = '110 m hurdles')
SELECT (SELECT "performance" FROM "table_203_102" WHERE "event" = '100 m') > (SELECT "performance" FROM "table_203_102" WHERE "event" = '110 m hurdles')
