Could you filter this list to show only the rows which are associated with body builders whose birthday value contains the work "January"?
SELECT T2.name, T2.birth_date FROM body_builder AS T1 JOIN people AS T2 ON T1.people_id   =   T2.people_id WHERE T2.Birth_Date LIKE "%January%"
filter list for body builders whose birthday contains 'January' refers to WHERE Birth_Date LIKE \"%January%\";
