Consider below table table.
Id balance
1 100
2 500
3 4000
I need output in below format.
Id balance begin_bal end_bal
1 100 0 100
2 500 100 600
3 4000 600 4600
A little bit of analytics, as you presumed:
SQL> with test (id, balance) as
2 (select 1, 100 from dual union all
3 select 2, 500 from dual union all
4 select 3, 4000 from dual
5 ),
6 temp as
7 (select id, balance, sum(balance) over (order by id) rsum
8 from test
9 )
10 select id,
11 balance,
12 nvl(lag(rsum) over (order by id), 0) begin_bal,
13 rsum end_bal
14 from temp
15 order by id;
ID BALANCE BEGIN_BAL END_BAL
---------- ---------- ---------- ----------
1 100 0 100
2 500 100 600

I have a pretty lengthy SQL query which I'm going to run on Oracle via hibernate. It consists of two nested selects. In the first select statement, a number of sums are calculated, but in one of them I want to filter the results using unique ids.
SELECT ...
SUM(NVL(CASE WHEN SECOND_STATUS= 50 OR SECOND_STATUS IS NULL THEN RECEIVE_AMOUNT END, 0) +
NVL(CASE WHEN FIRST_STATUS = 1010 THEN AMOUNT END, 0) +
NVL(CASE WHEN FIRST_STATUS = 1030 THEN AMOUNT END, 0) -
NVL(CASE WHEN FIRST_STATUS = 1010 AND (SECOND_STATUS= 50 OR SECOND_STATUS IS NULL) THEN RECEIVE_AMOUNT END, 0)) TOTAL, ...
And at the end:
... FROM (SELECT s.*, p.* FROM FIRST_TABLE s
JOIN SECOND_TABLE p ON s.ID = p.FIRST_ID
In one of the lines that start with NVL (second line actually), I want to add a distinct clause that sums the amounts only if first table ids are unique. But I don't know if this is possible or not. If yes, how would it be?
Assume such setup
select * from first;
ID AMOUNT
---------- ----------
1 10
2 20
select * from second;
SECOND_ID FIRST_ID AMOUNT2
---------- ---------- ----------
1 1 100
2 1 100
3 2 100
After the join you get the total sum of both amounts too high because the amount from the first table is duplicated.
select *
from first
join second on first.id = second.first_id;
ID AMOUNT SECOND_ID FIRST_ID AMOUNT2
---------- ---------- ---------- ---------- ----------
1 10 1 1 100
1 10 2 1 100
2 20 3 2 100
You must add a row_number that identifies the first occurence in the parent table and consider in the AMOUNT only the first row and resets it to NULL in the duplicated rows.
select ID,
case when row_number() over (partition by id order by second_id) = 1 then AMOUNT end as AMOUNT,
SECOND_ID, FIRST_ID, AMOUNT2
from first
join second on first.id = second.first_id;
ID AMOUNT SECOND_ID FIRST_ID AMOUNT2
---------- ---------- ---------- ---------- ----------
1 10 1 1 100
1 2 1 100
2 20 3 2 100
Now you can safely sum in a separate subquery
with tab as (
select ID,
case when row_number() over (partition by id order by second_id) = 1 then AMOUNT end as AMOUNT,
SECOND_ID, FIRST_ID, AMOUNT2
from first
join second on first.id = second.first_id
)
select id, sum(nvl(amount,0) + nvl(amount2,0))
from tab
group by id
;
ID SUM(NVL(AMOUNT,0)+NVL(AMOUNT2,0))
---------- ---------------------------------
1 210
2 120
Note also that this is an answer to your question. Some will argue that in your situation you should first aggregate and than join. This will also resolve your problem possible more elegantly.
Each row Total value go for the set OP value for the next row, except the first row

You can use recursive subquery factoring for that purpose like below. You need to rank your data as you have some gaps between IDs in your data. Column name = IS is not allowed, You should use "IS" enclosed by ".
with t1 ( ID, WAREHOUSEID, PRODUCTID, OP, RE, "IS", RNB, rnb_per_wh_prod) as (
select ID, WAREHOUSEID, PRODUCTID, OP, RE, "IS"
, row_number()over(order by WAREHOUSEID, PRODUCTID, ID) rnb
, row_number()over(partition by WAREHOUSEID, PRODUCTID order by ID) rnb_per_wh_prod
from Your_table t
), cte (ID, WAREHOUSEID, PRODUCTID, OP, RE, "IS", Total, RNB) as (
select ID, WAREHOUSEID, PRODUCTID, OP, RE, "IS", OP + RE - "IS", RNB
from t1
where rnb_per_wh_prod = 1
union all
select t1.ID
, t1.WAREHOUSEID
, t1.PRODUCTID
, case when t1.op = 0 then c.OP + c.RE - c."IS" else t1.OP end as OP
, t1.RE
, t1."IS"
, case when t1.op = 0 then c.OP + c.RE - c."IS" else t1.OP end + t1.RE - t1."IS" total
, t1.RNB
from cte c
join t1 on (t1.RNB = c.RNB + 1
and c.WAREHOUSEID = t1.WAREHOUSEID
and c.PRODUCTID = t1.PRODUCTID)
)
select ID, WAREHOUSEID, PRODUCTID, OP, RE, "IS", TOTAL
from cte
order by id
;
If I understand the problem correctly, "every 3 row" is a coincidence in your data; in fact, the computation must be done separately for each product in each warehouse, no matter how many rows there are for each distinct combination. And the "id" column is in reality some sort of timestamp - ordering is by "id".
If so, you can do it all in a single query using analytic sum(). Instead of creating a table for testing, I included all the sample data in a WITH clause at the top of the query itself; you can remove the WITH clause, and use your actual table and column names. I also changed the column name is to is_ since is is a reserved keyword, it can't be a column name.
Note also that I am ignoring your existing total column completely (I didn't even include it in the sample data); I assume it doesn't exist in your real-life data, and instead it is part of your attempt at a solution. You don't need it - not in the way you have it in your question.
with
sample_data (id, warehouseid, productid, op, re, is_) as (
select 1, 100, 10000, 10, 0, 0 from dual union all
select 2, 100, 10000, 0, 0, 5 from dual union all
select 4, 100, 10000, 0, 15, 0 from dual union all
select 5, 101, 10001, 15, 0, 0 from dual union all
select 6, 101, 10001, 0, 0, 5 from dual union all
select 8, 101, 10001, 0, 15, 0 from dual union all
select 9, 101, 10002, 25, 0, 0 from dual union all
select 10, 101, 10002, 0, 0, 10 from dual union all
select 11, 101, 10002, 0, 15, 0 from dual
)
select id, warehouseid, productid,
nvl(sum(op + re - is_) over (partition by warehouseid, productid
order by id rows between unbounded preceding and 1 preceding),
op) as op,

sum(op + re - is_) over

I need to separate delimited string value into separate rows
What I need is:
FAILUREID TNO
1 t01
1 t02

2 t04
2 t05
But using the code below I receided
1 t01
1 t02
1 t03
1 t03
1 t03
1 t02
1 t03
2 t04
2 t05
2 t05
Some lines are duplicated. Where is the bug in the code below, How to fix it ? ( distinct is not a solution)
with data as
( select 1 as FailureID
,'t01;t02;t03' as Tickets
from dual
union
select 2
,'t04;t05'
from dual
)
select FailureID
,regexp_substr(Tickets, '[^;]+', 1, level) as TNO
from data
connect by regexp_substr(tickets, '[^;]+', 1, level) is not null
order by failureid
Here's how (the difference begins at line #13):
SQL> with data as
2 ( select 1 as FailureID
3 ,'t01;t02;t03' as Tickets

i have a table in hive with two columns: session_id and duration_time like this:
|| session_id || duration||
1 14
1 10
1 20
1 10
1 12
1 16
1 8
2 9
2 6
2 30
2 22
i want to add a new column with unique id when:
the session_id is changing or the duration_time > 15
i want the output to be like this:
session_id duration unique_id
1 14 1
1 10 1
1 20 2
1 10 2
1 12 2
1 16 3
1 8 3
2 9 4
2 6 4
2 30 5
2 22 6
any ideas how to do that in hive QL?
thanks!
SQL tables represent unordered sets. You need a column specifying the ordering of the values, because you seem to care about the ordering. This could be an id column or a created-at column, for instance.
You can do this using a cumulative sum:
select t.*,
sum(case when duration > 15 or seqnum = 1 then 1 else 0 end) over
(order by ??) as unique_id
from (select t.*,
row_number() over (partition by session_id order by ??) as seqnum
from t
) t;
First off, I'm a total Oracle noob although I'm very familiar with SQL. I have a single cost column. I need to calculate the total cost, the percentage of the total cost, and then a running sum of the percentages. I'm having trouble with the running sum of percentages because the only way I can think to do this uses nested SUM functions, which isn't allowed.
Here's what works:
SELECT cost, SUM(cost) OVER() AS total, cost / SUM(cost) OVER() AS per
FROM my_table
ORDER BY cost DESC
Here's what I'm trying to do that doesn't work:
SELECT cost, SUM(cost) OVER() AS total, cost / SUM(cost) OVER() AS per,
SUM(cost/SUM(cost) OVER()) OVER(cost) AS per_sum
FROM my_table
ORDER BY cost DESC
Am I just going about it wrong, or is what I'm trying to do just not possible? By the way I'm using Oracle 10g. Thanks in advance for any help.
You don't need the order by inside that inline view, especially since the outer select is doing an order by the order way around. Also, cost / SUM(cost) OVER () equals RATIO_TO_REPORT(cost) OVER ().
An example:
SQL> create table my_table(cost)
2 as
3 select 10 from dual union all
4 select 20 from dual union all
5 select 5 from dual union all
6 select 50 from dual union all
7 select 60 from dual union all
8 select 40 from dual union all
9 select 15 from dual
10 /
Table created.
Your initial query:
SQL> SELECT cost, SUM(cost) OVER() AS total, cost / SUM(cost) OVER() AS per
2 FROM my_table
3 ORDER BY cost DESC
4 /

Quassnoi's query contains a typo:
SQL> SELECT cost, total, per, SUM(running) OVER (ORDER BY cost)
2 FROM (
3 SELECT cost, SUM(cost) OVER() AS total, cost / SUM(cost) OVER() AS per

6 cost DESC
7 )
8 /
SELECT cost, total, per, SUM(running) OVER (ORDER BY cost)
*
ERROR at line 1:
ORA-00904: "RUNNING": invalid identifier
And if I correct that typo. It gives the right results, but wrongly sorted (I guess):
SQL> SELECT cost, total, per, SUM(per) OVER (ORDER BY cost)
2 FROM (
3 SELECT cost, SUM(cost) OVER() AS total, cost / SUM(cost) OVER() AS per
4 FROM my_table
