You're missing a BEGIN and your NUMBER variable should be declared with a comma not a period.
create or replace function age (
pDateOfBirth date ) return number is
l_age number(5,2);
begin
l_age := ( sysdate - pDateOfBirth ) / 365.25;
return l_age;
end;
/
You've now edited the question to include the BEGIN but you haven't fixed your declaration of the variable. As your error message says:
PLS-00325: non-integral numeric literal 5.2 is inappropriate in this context
Personally, I believe you're calculating age incorrectly. There are 365 or 366 days in a year. I'd do this instead, which uses internal Oracle date functions:
function get_age (pDOB date) return number is
/* Return the the number of full years between
the date given and sysdate.
*/
begin
return floor(months_between(sysdate, pDOB)/12);
end;
That is if you only want the number of full years.

Question is : Function: Create a Function named 'find_credit_card' which takes card_no as input and returns the holder name of type varchar.
Function name: find_credit_card
Input Parameter: card_no with data type as varchar
Output variable : holder_name with data type as varchar(30)
Hint: Add '/' after the end statement
Refer to the schema.
My code :-
CREATE OR REPLACE FUNCTION find_credit_card(card_no IN VARCHAR2(255))
RETURN VARCHAR
IS
holder_name VARCHAR(255)
BEGIN
SELECT name
INTO holder_name
from credit_card
where card_number = card_no;
RETURN(holder_name);

Alternatively, query user_errors:
select line, position, text
from user_errors
where name = 'FIND_CREDIT_CARD';
Oracle says that there are two errors:
first one means that function's parameter shouldn't have size, so - not card_no in varchar2(255) but only card_no in varchar2
another one means that you forgot to terminate line where local variable was declared (missing semi-colon at the end of that line):
holder_name VARCHAR(255);
However, consider inheriting datatype from column description. If it is ever changed, you wouldn't have to modify your code.
Furthermore, it would be good if you distinguish parameters and local variables from column names. How? Use prefixes, e.g. par_ for parameters, l_ or v_ for local variables.
Also, Oracle recommends us to use varchar2, not varchar.
Finally, that function might look like this:
SQL> CREATE OR REPLACE FUNCTION find_credit_card
2 (par_card_number IN credit_card.card_number%TYPE)
3 RETURN credit_card.name%type
4 IS
5 l_holder_name credit_card.name%TYPE;

7 SELECT name
8 INTO l_holder_name
9 FROM credit_card
10 WHERE card_number = par_card_number;

12 RETURN l_holder_name;

Where is my mistake? I can't find it, it doesn't make any sense.
(I translated this warning message from my language. I hope I did it right.)
I have just tried it in Command Window and it works. Why doensn't it work in Oracle SQL Developer sql worksheet?
There is nothing wrong with your posted code. The issue might be with your client or the way you are compiling the code.
As you have mentioned PL/SQL Developer in the tags, it might be possible that you have some extra characters in the SQL Worksheet and you are compiling the function as a script, thus the compiler finds it erroneous.
Here is a demo in SQL*Plus, and there is no error:
SQL> CREATE OR REPLACE FUNCTION customer_city_function(i_deptno IN number)

The only difference in my code is that I have used EMP table instead of CUSTOMERS table and the input parameter is DEPTNO instead of CITY_IN. Rest everything is same and function compiles and executes without any errors.

You are selecting two columns, but you only provide one variable to put them in.

or
SELECT Formula || Pharname INTO returnString

I would be shocked if you really wanted the input parameter to be declared as CHAR. Almost always, you should use VARCHAR2 for character strings. It is exceptionally rare to come across a case where you really want the blank-padding semantics of a CHAR.
this is working dude;
create or replace
procedure greet(message in char)
as
begin
dbms_output.put_line('Greet Message : ' || message);
end;
see main property of char datatype is is the length of input data is less than the size you specified it'll add blank spaces.this case is not happened for varchar2.
in procedure above mentioned char property is violated so it's almost treat like varchar2. so if you remove size of input parameter it will work and also char support maximum length of input.
I'm trying to create a user defined function in Oracle that will return a DATE when given a text argument containing a date substring. I've tried a couple ways of writing this, and all seem to throw the same error:
CREATE OR REPLACE FUNCTION lm_date_convert (lm_date_in IN VARCHAR2(50))
RETURN DATE DETERMINISTIC IS
BEGIN
RETURN(TO_DATE(REGEXP_REPLACE(lm_date_in, '([[:digit:]]{2})[-/.]*([[:digit:]]{2})[-/.]*([[:digit:]]{4})','\3-\1-\2'), 'YYYY-MM-DD'));
END;
the error:
FUNCTION lm_date_convert Compiled. 1/46
PLS-00103: Encountered
the symbol "(" when expecting one of
the following:
:= . ) , # % default character The
symbol ":=" was substituted for "(" to
continue.
Any thoughts on this, and general UDF writing tips (and good references) are welcome! Thanks.
We cannot restrict the datatype when specifying parameters in stored procedures. That is, just use VARCHAR2 rather than VARCHAR2(50).
Just to prove I'm reproducing your problem ...
SQL> CREATE OR REPLACE FUNCTION lm_date_convert (lm_date_in IN VARCHAR2(50))
2 RETURN DATE DETERMINISTIC IS
3 BEGIN
4 RETURN(TO_DATE(REGEXP_REPLACE(lm_date_in, '([[:digit:]]{2})[-/.]*([[:digit:]]{2})[-/.]*([[:digit:]]{4})','\3-\1-\2'), 'YYYY-MM-DD'));

"If you really do want a VARCHAR2(50)
then declare a type of VARCHAR2(50)
and use the type."
Declaring a SQL TYPE to enforce sizing is a bit of overkill. We can declare SUBTYPEs in PL/SQL but their sizes are not actually enforced in stored procedure signatures. However there are workarounds as I discuss in this other thread.
As an aside, why are you using Regex to solve this problem? Or rather, what problem are you trying to solve which cannot be solved with TO_CHAR and TO_DATE? Oracle's pretty forgiving with format masks.
