Hi Ashish,

You can use the minus from sysdate to client d_o_b and see there are lot of date functions available with Oracle. Read them and use them ...

Bye

I'd use the MONTHS_BETWEEN built-in:
SQL> SELECT trunc(months_between(sysdate,d_o_b)/12)||' years and '||
  2         trunc(mod(months_between(sysdate,d_o_b),12))||' months.'  age
  3  FROM   ( SELECT to_date('01/21/1976','MM/DD/YYYY') d_o_b
  4           FROM   dual
  5         )
  6  /

AGE
------------------------------
30 years and 8 months.


A pure subtraction (sysdate-d_o_b) returns the number of days between the two dates. Months_between is easier to convert to years.

SQL> select round((sysdate - to_date('01-01-2006', 'dd-mm-yyyy'))/365, 0) from dual;

ROUND((SYSDATE-TO_DATE('01-01-2006','DD-MM-YYYY'))/365,0)
---------------------------------------------------------
                                                        1


Round won't do.
Neither will 365: ever heard of leap years?

Go with Maaher's solution.

Well, if everything else fails, you could always call that specific customer and ask him "Hello there, how old are you?".

hi
i hope u are fine.

you are using this syntax

select trunc((to_char('10/14/2006', 'mm/dd/yyyy')-to_char('02/08/1980', 'mm/dd/yyyy'))/10000)as age

-------------------------------------------

you should use like this

select trunc((sysdate-birthday)/365) as age from tabname;
for weeks devide with 52
for months devide with 12
for days use no division just add 1
for hours multiply with 24
for minutes multiply with 24*60
i hope this will solve your problem

I can't believe you didn't manage to get the answer to the same question you asked a few days ago http://www.orafaq.com/forum/fa/1604/0/.

By the way, what does it mean "dnt try to get excuse"? Who? You didn't try, or Ross shouldn't try?

His answer was fair enough: you are converting a string back into string. Besides that, SYSDATE IS of a DATE datatype - it doesn't need conversion. Moreover, what should "&sysdate" be?

Basically, this is what you need:

SELECT SYSDATE - TO_DATE('&birthday', 'dd.mm.yyyy') FROM dual;

Check Shahidmughal's answer to see how to get months, days etc.

"u" is not a member here. Use plain English next time. Save your MSN lingo for MSN! Besides, he already hinted to use TO_DATE instead of TO_CHAR.

Does not compute. What on earth are you talking about?

Obviously it is not right.

Some tips:

  1. Don't start a new topic on the same subject.
  2. Use plain English. No "U", no "dnt", no IM speak.
  3. Be polite.
  4. Above all: read the tips and tricks sticky. It is the first topic in this forum.


I already gave you a solution in your previous topic. I have merged them.

About the ampersant (&-sign): it is used for substitution variables in tools like SQL*Plus. SYSDATE, is an oracle built-in. It is already a value. No need for an ampersant. SYSDATE is already a DATE. Keep it that way and don't convert it to a string via TO_CHAR. You want to convert your date of birth from a string to a date. TO a DATE. Would that be TO_DATE or TO_CHAR? Wink

I have merged the topics. Again: read the sticky (tips&tricks).
