Any Function which can solve my problem.

Question

Hi all
I am working on Character based report from which i use to take print on my check using dot matrix printer.
my query is
1) when i want to type my amount in words there may be chances of overlapping my amount in words with other field because may be the value is too large.
for e.g here in front of rupee that much character be fix other may go to other line.
PAY............................................................
RUPEES....................................................... RS.2206
i have tried
SELECT SUBSTR('Two Thousand Two Hundred Six only',1,25) FROM DUAL
SELECT SUBSTR('Two Thousand Two Hundred Six only',25,100) FROM DUAL
but some time the value get changed then like 3206
then
if we will use same in report
SELECT SUBSTR('Three Thousand Two Hundred Six only',1,25) FROM DUAL
SELECT SUBSTR('Three Thousand Two Hundred Six only',25,100) FROM DUAL
PAY............................................................
RUPEES.Three Thousand Two Hundre. RS.2206
ed Six only.
run time in report.it should not come like this.
is there any function or solution for this.

Answer 1

assuming your max length is 25, this sql will split the string at the last blank:
WITH t As (
    SELECT 'Three Thousand Two Hundreed Six only.' text FROM dual UNION
    SELECT 'Two Hundreed Six only.' FROM dual UNION
    SELECT 'Three Thousand Three Hundreed Three only.' FROM dual
SELECT
    SUBSTR(text, 1, INSTR(SUBSTR(text, 1, 25), ' ', -1) - 1) row1,
    SUBSTR(text, INSTR(SUBSTR(text, 1, 25), ' ', -1) + 1) row2
FROM t;
ROW1
ROW2
Three Thousand Three
Hundreed Three only.
Three Thousand Two
Hundreed Six only.
Two Hundreed Six
only.
