Find employees aged 16 and younger in ORACLE SQL


im trying to write a query which finds any staff which are 16 or younger using  a CTE.

BIRTH_DATE <= sysdate - 16*12

This isnt working though.

Is my syntax wrong?

You need to check for greater or equal, not less or equal. And dates are represented in fractions of a day, not months:
   BIRTH_DATE >= sysdate - 16*365

However, it is much better to use the date specific functions or intervals:
   BIRTH_DATE >= sysdate - interval '16' years
   BIRTH_DATE >= add_months(sysdate, -16*12)
