DECLARE
BIRTHDAY DATE:=TO_DATE(TO_DATE('&BIRTHDAY','DD-MON-RRRR'),'DD/MON/RRRR');
CURRENT_DATE DATE:=TO_DATE(SYSDATE);
RESULT VARCHAR2(100);
BEGIN
RESULT:=TRUNC((CURRENT_DATE-BIRTHDAY)/365);
IF TO_CHAR(BIRTHDAY,'MMDD') BETWEEN 0321 AND 0419 THEN
&D('YOU ARE ARIES'||' AND YOU ARE '||RESULT||' YEARS OLD');
ELSIF TO_CHAR(BIRTHDAY,'MMDD') BETWEEN 0420 AND 0520 THEN
&D('YOU ARE TAURUS'||' AND YOU ARE '||RESULT||' YEARS OLD');

This is awful.
SYSDATE is already a date, this is an horror.
| Quote: | TO_CHAR(BIRTHDAY,'MMDD') BETWEEN 0321 AND 0419
|
TO_CHAR returns string, 321 and 419 are numbers, you compare strings and numbers, this is scary.
This is not defined.
Well, one error per line. You get the highest score!
But the best one is:
| Quote: | TO_CHAR(BIRTHDAY,'MMDD') BETWEEN '21-MAR' AND '19-april'
|
It is always FALSE. Guess why...

Michel

Nothing to do.
It is wrong, it is wrong.
TO_DATE returns a date. What can be TO_DATE of a date? How can a date be converted to a date? It is a date!
