CREATE TABLE table_78973 ("Name" CLOB, "Position" CLOB, "Height" CLOB, "Weight" FLOAT, "Year" CLOB, "Home Town" CLOB)

Can you tell me the average Weight that has Height of 6-9?
SELECT AVG("Weight") FROM table_78973 WHERE "Height" = '6-9'
SELECT AVG("Weight") FROM "table_78973" WHERE "Height" = '6-9'
