Duplicating rows in an oracle query - oracle

Question

I am to create a query which will be used for printing labels in our project and find it difficult since the count of the number of labels is based on a string. I have made a query that looks like this:
SELECT
wipdatavalue
, containername
, l
, q as qtybox
, d
, qtyperbox AS q
, productname
, dt
, dsn
, CASE
WHEN instr(wipdatavalue, '-') = 0
THEN
to_number(wipdatavalue)
ELSE
to_number(substr(wipdatavalue, 1, instr(wipdatavalue, '-') - 1))
END AS una
, CASE
WHEN instr(wipdatavalue, '-') = 0
THEN
to_number(wipdatavalue)
ELSE
to_number(substr(wipdatavalue, instr(wipdatavalue, '-') + 1))
END AS dulo
, ROW_NUMBER() OVER (ORDER BY containername) AS n
, count(*) over() m
FROM trprinting_ls
WHERE containername = 'TRALTESTU0A'
GROUP BY wipdatavalue, containername, l, q, d, qtyperbox, productname, dt, dsn
ORDER BY wipdatavalue
The query above will result to below:
But actually, I have to display the first Item (Wipdatavalue 1-4) not only once but four times to look something like this:
I have tried another query that runs fine but when I try to load it in our project, it does not print the label. We found out that it is because of the WITH statement and we don't know why. The query is:
WITH DATA (WIPDATAVALUE, CONTAINERNAME, L, Q, D, QTYBOX, PRODUCTNAME, DT, una, dulo, m1, n)
AS (SELECT WIPDATAVALUE, CONTAINERNAME, L, Q, D, QTYBOX, PRODUCTNAME, DT, una, dulo,(dulo - una) + 1 AS m1,una n
FROM (SELECT WIPDATAVALUE, CONTAINERNAME, L, Q, D, QTYPERBOX AS QTYBOX, PRODUCTNAME, DT,
CASE
WHEN instr(wipdatavalue, '-') = 0
THEN
to_number(wipdatavalue)
ELSE
to_number(substr(wipdatavalue, 1, instr(wipdatavalue, '-') - 1))
END AS una,
CASE
WHEN instr(wipdatavalue, '-') = 0
THEN
to_number(wipdatavalue)
ELSE
to_number(substr(wipdatavalue, instr(wipdatavalue, '-') + 1))
END AS dulo
FROM trprinting_ls
WHERE containername = 'TRALTESTU0A'
)
UNION ALL
SELECT WIPDATAVALUE, CONTAINERNAME, L, Q, D, QTYBOX, PRODUCTNAME, DT, una, dulo, m1, n + 1
FROM DATA
WHERE n + 1 <= dulo)
SELECT WIPDATAVALUE, CONTAINERNAME, L, Q, D, QTYBOX, PRODUCTNAME, DT, una, dulo, n,
count(*) OVER () m
FROM DATA
ORDER BY n, wipdatavalue
Thanks guys for helping out.

Answer 1

Try this
select *
from your_data
start with instr(Wipdatavalue, '1') > 0
connect by level between regexp_substr(Wipdatavalue, '^\d+')
and regexp_substr(Wipdatavalue, '\d+$')
It's a simplified example
The regexp_substr can be replaced with substr and instr if you like (may also be faster)
Here is a sqlfiddle demo

Answer 2

Try this Query
select column_name, count(column_name)
from table
group by column_name
having count (column_name) > 1;
