success with compilation error on Function creation, why?

Question

I tried to create this function in Oracle Apex 5, SQL Commands and it resulted in this error 'ORA-24344: success with compilation error.' Why do you think so? I'm trying to create a random generated code.

CREATE OR REPLACE FUNCTION generate_code()
    return varchar2
    AS
    code varchar2;
    BEGIN
    code := DBMS_RANDOM.value(1,100);
    return code;
    END;

Answer 1

error in syntax, see below

the correct syntax is

CREATE OR REPLACE FUNCTION generate_code

    return varchar2
    AS
    code varchar2(100);
    BEGIN
    code := DBMS_RANDOM.value(1,100);
    return code;
    END;

original syntax with error description:

SQL> CREATE OR REPLACE FUNCTION generate_code()
  2
  3      return varchar2
  4      AS
  5      code varchar2;
  6      BEGIN
  7      code := DBMS_RANDOM.value(1,100);
  8      return code;
  9      END;
