CREATE TABLE body_builder (People_ID VARCHAR2, Total NUMBER)
CREATE TABLE people (Height VARCHAR2, People_ID VARCHAR2)

SELECT T2.Height FROM body_builder AS T1 JOIN people AS T2 ON T1.People_ID = T2.People_ID WHERE T1.Total < 315
SELECT "T2"."Height" FROM "body_builder" "T1" JOIN "people" "T2" ON "T1"."People_ID" = "T2"."People_ID" WHERE "T1"."Total" < 315
