CREATE TABLE table_name_8 (_jerk VARCHAR2, clean_ NUMBER, total__kg_ VARCHAR2, snatch VARCHAR2)

What is the clean & jerk when the total (kg) is more than 204, and snatch is more than 98?
SELECT AVG(clean_) & _jerk FROM table_name_8 WHERE total__kg_ > 204 AND snatch > 98
SELECT AVG("clean_") & "_jerk" FROM "table_name_8" WHERE "snatch" > 98 AND "total__kg_" > 204
