AMT_IN_WORDS FROM BHAV;

Thank you in advance...

Answer 1

You can creation a function.
CREATE OR REPLACE FUNCTION big_amt_in_words (p_input VARCHAR2) RETURN VARCHAR2
IS
v_running_input NUMBER;
v_num NUMBER;
v_amt_in_words VARCHAR2(2000);
BEGIN
v_running_input := P_input;
FOR i IN (
SELECT RPAD(1, (rownum*3)+1, 0) num_value,
CASE LENGTH(RPAD(1, (rownum*3)+1, 0))
WHEN 4 THEN 'THOUSAND'
WHEN 7 THEN 'MILLION'
WHEN 10 THEN 'BILLION'
WHEN 13 THEN 'TRILLION'
WHEN 16 THEN 'QUADRILLION'
WHEN 19 THEN 'QUINTILLION'
WHEN 22 THEN 'SEXTILLION'
WHEN 25 THEN 'SEPTILLION'
WHEN 28 THEN 'OCTILLION'
END place_value
FROM DUAL
CONNECT BY rownum < 10
ORDER BY rownum desc)
LOOP
v_num := TRUNC(v_running_input/i.num_value,0);
IF v_num > 0 THEN
v_amt_in_words := v_amt_in_words||' '||TO_CHAR(TO_DATE(v_num,'J'), 'JSP')||' '||i.place_value;
v_running_input := v_running_input - (v_num * i.num_value);
END IF;
END LOOP;
v_amt_in_words := v_amt_in_words||' '||TO_CHAR(TO_DATE(TRUNC(v_running_input),'J'), 'JSP')
||' AND '||UPPER(TO_CHAR(TO_DATE((ROUND(v_running_input-TRUNC(v_running_input),2)*100),'J'),'JSP'))||' CENTS';
RETURN TRIM(v_amt_in_words);
END;
/
To use it,
SELECT BIG_AMT_IN_WORDS(65763245345658.12) amt_in_words
FROM DUAL;
Output
---------------------------------------------
SIXTY-FIVE TRILLION SEVEN HUNDRED SIXTY-THREE BILLION TWO HUNDRED FORTY-FIVE MILLION THREE HUNDRED FORTY-FIVE THOUSAND SIX HUNDRED FIFTY-EIGHT AND TWELVE CENTS

Answer 2

The error is raised since the value of high that you have shown is a decimal, that cannot be cast as an integer implicitly, unlike 100.00. So, it cannot be converted to Julian date.
SELECT UPPER(TO_CHAR(TO_DATE(100.10,'J'),'JSP'))AMT_IN_WORDS FROM DUAL;
This causes
ORA-01830: date format picture ends before converting entire input
string
This can be resolved by rounding the decimal to the nearest integer.
SELECT UPPER(TO_CHAR(TO_DATE(ROUND(100.10),'J'),'JSP'))AMT_IN_WORDS FROM DUAL;
| AMT_IN_WORDS |
|--------------|
| ONE HUNDRED |
