when I'm using SQL Navigator my query is working but when I call from frontend my query returns 0
This my query:
select *
from (
select nvl(b.income,0) as income, a.curDate as curDate, nvl(c.outlay,0) as outlay
from (
select to_char(sysdate-l_day,'DD.MM.YYYY') as curDate,
to_number(to_char(sysdate-l_day,'yyyymmdd')) as range_period
from (
select column_value as l_day
from table(sys.odcinumberlist(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14))
)
order by l_day desc
) a
left join (
select to_number(to_char(created_date,'yyyymmdd')) as range_period,
sum(summa) as income
from factory_plats
where status=1 and factories_id = #{factories_id}
and created_date between to_date (sysdate-20,'dd.mm.yyyy') and to_date (sysdate,'dd.mm.yyyy') + 1 - 1 /24/60/60
group by to_number(to_char(created_date,'yyyymmdd'))
) b on a.range_period = b.range_period
left join (
select to_number(to_char(ci.created_date,'yyyymmdd')) as range_period,
sum(summa) as outlay,
f.factories_id as factories_id
from card_inputs ci
left join filials f on ci.filials_id = f.id
where ci.status=1 and f.factories_id = #{factories_id}
and ci.created_date between to_date (sysdate-20,'dd.mm.yyyy') and to_date (sysdate,'dd.mm.yyyy') + 1 - 1 /24/60/60
group by to_number(to_char(ci.created_date,'yyyymmdd')), f.factories_id
) c on a.range_period = c.range_period
)
This query is working SQL Navigator, but when I call from frontend returns 0
I want to apply the group by function based on columns generated by the PIVOT function.
In the query below, I wanted to apply Sum(TC.MB_Usage) so I could use group by at the end. However I am unable to apply the group by function to columns that are generated by the PIVOT function (SITES).

You will need to specify the individual columns in your GROUP BY.
It looks like your SITES alias will have the columns IMSI, MDN, IMSI_MDN, and then 1,2,3,4,5,6,7,8,9,10,11,12,13 from the PIVOT clause.
So try listing those individually, and for the numeric ones put them in quotes:
GROUP BY
...
SITES."1", SITES."2", etc.
I am using LISTAGG function for my query, however, it returned an ORA-01489: result of string concatenation is too long error. So I googled that error and found out I can use ON OVERFLOW TRUNCATE and I implemented that into my SQL but now it generates missing right parenthesis error and I can't seem to figure out why?
My query
SELECT DISTINCT cust_id, acct_no, state, language_indicator, billing_system, market_code,
EMAIL_ADDR, DATE_OF_CHANGE, TO_CHAR(DATE_LOADED, 'DD-MM-YYYY') DATE_LOADED,
(SELECT LISTAGG( SUBSTR(mtn, 7, 4),'<br>' ON OVERFLOW TRUNCATE '***' )

With a little bit of help by XML, you might get it work. Example is based on HR schema.

The problem with this query is with the use of CONCAT operator (||). Concat operator returns char1 concatenated with char2. The string returned is in the same character set as char1. So here concat operator is trying to return varchar2, which has limit of 4000 characters and getting exceeded. This problem may also come when we try to CONCAT a VARCHAR2 with CLOB. So here I want simply convert its first string to CLOB and avoid this error. After converting first string to CLOB, CONCAT operator will return string of CLOB type
So I add the TO_CLOB to convert the types but then I have the next error:
ORA-00932: inconsistent datatypes: expected - got CLOB

You can build hierarchy CLOB path with subquery factoring syntax This may run really slow. Consider having two path columns - one for varchar2 result and one for CLOB. Build varchar2 till size allows, and keep NULL in CLOB path, and switch to CLOB when out of varchar2 capacity. This is a different question though.

You might found this page, because you're trying to aggregate strings longer than 4000 characters and remembered the different techniques.
If so, I created a small example, based on #B Samedi's answer to help you out, when you're not able to use user defined aggregates
with dummy_text as (
select 'teststring ' || rownum str from dual connect by rownum < 2
)
, indexed_strings as (
select str, row_number() over (order by 'x') rn, ',' separator from dummy_text
)
, hier (str, lvl) as (
select to_clob(i.str), rn from indexed_strings i where rn = (select max(rn) from indexed_strings)
union all
select concat(to_clob(concat(i.str, i.separator)), h.str), h.lvl - 1 from indexed_strings i join hier h on h.lvl - 1 = i.rn
)
select str from hier where lvl = 1
In DB2, I have this query to list numbers 1-x:
select level from SYSIBM.SYSDUMMY1 connect by level <= "some number"
But this maxes out due to SQL20450N Recursion limit exceeded within a hierarchical query.
How can I generate a list of numbers between 1 and x using a select statement when x is not known at runtime?
I found an answer based on this post:
WITH d AS
(SELECT LEVEL - 1 AS dig FROM SYSIBM.SYSDUMMY1 CONNECT BY LEVEL <= 10)
SELECT t1.n
FROM (SELECT (d7.dig * 1000000) +
(d6.dig * 100000) +
(d5.dig * 10000) +
(d4.dig * 1000) +
(d3.dig * 100) +
(d2.dig * 10) +
d1.dig AS n
FROM d d1
CROSS JOIN d d2
CROSS JOIN d d3
CROSS JOIN d d4
CROSS JOIN d d5
CROSS JOIN d d6
CROSS JOIN d d7) t1
JOIN ("subselect that returns desired value as i") t2
ON t1.n <= t2.i
ORDER BY t1.n
That's how I usually create lists:
For your example
numberlist (num) as
(
select min(1) from anytable
union all
select num + 1 from numberlist
where num <= x
)
I did something like this when I wanted a list of values to correspond with months:
with t1 (mon) as (
values (1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12)
)
select * from t1
It seems a bit kludgy, but for a small list like 1-12, or even 1-50, it did what I needed it to.
It's nice to see someone else tagging their questions with DB2.
If you have any table known to have more than x rows, you can always do:
select * from (
select row_number() over () num
from my_big_table
) where num <= x
or, per bhamby's suggestion:
select row_number() over () num
from my_big_table
fetch first X rows only
For DB2 you can use recursive common table expressions (cf. IBM documentation on recursive CTE):
with max(num) as (
select 1 from sysibm.sysdummy1
)
,result (num) as (
select num from max
union ALL
select result.num+1
from result
where result.num<=100
)
select * from result;
