Converting integer value from a db column to text

问题:

I have a requirement in db.

1).Table ABC, column: check_amount number number(18,4). This basically contains check amount for eg. 3000.50 to be paid to an employee.

Now a cheque is issued and that check contains this check_amount in number as well as in text form.for eg.check will have:

pay to <emplyee_name> ****$3000.50**** ****THREE THOUSAND DOLLARS AND FIFTY CENTS****

I have to generate this text using DB column value and display that on check.

Can anybody help me out, how can i achieve this in oracle 11g ?

Hint:I have heard of Julien format, but that is not working. Any suggestions is greatly appreciated.

Since Julian format works only for whole numbers, you can separate the decimal parts and then apply the Julian format trick to the separated numbers. Here's a simple demo.

DECLARE
   x   NUMBER (8, 2) := 1253.5;
   y   NUMBER;
   z   NUMBER;
BEGIN
   y := FLOOR (x);
   z := 100 * (x - y);
   DBMS_OUTPUT.put_line (TO_CHAR (TO_DATE (y, 'j'), 'jsp'));

   IF (z > 0)
   THEN
      DBMS_OUTPUT.put_line (TO_CHAR (TO_DATE (z, 'j'), 'jsp'));
   END IF;
EXCEPTION
   WHEN OTHERS
   THEN
      DBMS_OUTPUT.put_line ('err:' || SQLERRM);
END;

There is a limitation while using Julian dates ,It ranges from 1 to 5373484. That’s why if you put the values after 5373484, it will throw you an error as shown below:

ORA-01854: julian date must be between 1 and 5373484

To cater the above problem ,create a function ,and with little trick with j->jsp ,you can fetch the desired result.

CREATE OR REPLACE FUNCTION spell_number (p_number IN NUMBER)
   RETURN VARCHAR2
AS
   TYPE myArray IS TABLE OF VARCHAR2 (255);
   v_decimal     PLS_INTEGER;

   l_str myArray
     := myArray ('',
                 ' thousand ',
                 ' million ',
                 ' billion ',
                 ' trillion ',
                 ' quadrillion ',
                 ' quintillion ',
                 ' sextillion ',
                 ' septillion ',
                 ' octillion ',
                 ' nonillion ',
                 ' decillion ',
                 ' undecillion ',
                 ' duodecillion ');

   l_num      VARCHAR2 (50) DEFAULT TRUNC (p_number);
   l_return   VARCHAR2 (4000);
BEGIN
  FOR i IN 1 .. l_str.COUNT
   LOOP
     EXIT WHEN l_num IS NULL;

      IF (SUBSTR (l_num, LENGTH (l_num) - 2, 3) <> 0)
      THEN
         l_return :=
            TO_CHAR (TO_DATE (SUBSTR (l_num, LENGTH (l_num) - 2, 3), 'J'),
                     'Jsp')
             || l_str (i)
             || l_return;
      END IF;

     l_num := SUBSTR (l_num, 1, LENGTH (l_num) - 3);
   END LOOP;

   v_decimal := 100* (p_number -TRUNC(p_number)) ;

   IF v_decimal>0 THEN 

       RETURN l_return ||' Dollars AND '||TO_CHAR (TO_DATE (v_decimal, 'j'), 'jsp')|| ' Cents';        


  ELSE

   RETURN l_return ||' Dollars' ;
  END IF;

END;

select  spell_number(122344343444444.23) from dual;

Output:

One Hundred Twenty-Two trillion Three Hundred Forty-Four billion Three Hundred Forty-Three million Four Hundred Forty-Four thousand Four Hundred Forty-Four Dollars AND twenty-three Cents Blog Link
