Query to get data with minimum query cost - sql

I have a table, structure like this:
BID_FK AccountID Amount
1 1-1-1-1-1-1-1 4050
1 1-1-1-1-1-1-1 4050
1 1-1-1-1-1-1-1 4050
1 1-1-1-1-1-1-1 4050
1 1-1-1-1-1-1-2 500
1 1-1-1-1-1-1-2 500
1 1-1-1-1-1-1-2 500
1 1-1-1-1-1-1-2 500
2 1-1-1-1-1-1-1 6580
2 1-1-1-1-1-1-1 6580
2 1-1-1-1-1-1-1 6580
2 1-1-1-1-1-1-1 6580
2 1-1-1-1-2-1-1 1000
2 1-1-1-1-2-1-1 1000
2 1-1-1-1-2-1-1 1000
2 1-1-1-1-2-1-1 1000
I want to query for getting out put like this :
AccountID Amount(BID_FK = 1) Amount (BID_FK = 2)
1-1-1-1-1-1-1 16200 26320
1-1-1-1-1-1-2 2000 0
1-1-1-1-2-1-1 0 4000
With minimum query cost because I have large number of data.
Any help would be highly appreciated!

Maybe something like this could help?
SELECT
AccountID,
SUM(CASE WHEN BID_FK=1 THEN Amount ELSE 0 END) AMOUNT1,
SUM(CASE WHEN BID_FK=2 THEN Amount ELSE 0 END) AMOUNT2
FROM yourtable
GROUP BY AccountId

SELECT AccountID,
SUM( CASE WHEN BID_FK=1 THEN Amount ELSE 0 END) AS `Amount(BID_FK = 1)`
SUM( CASE WHEN BID_FK=2 THEN Amount ELSE 0 END) AS `Amount(BID_FK = 2)`
FROM yourTable
GROUP BY AccountID

in oracle sql query how to solve this.
please help me
I have try this
select
item_id,
(case month_in=1 then sum(amout) end) AS januari
from table
group by item_id, month_in
order by item_id asc
but not working as I expected
We can try a pivot query here:
SELECT
item_id,
SUM(CASE WHEN month_in = 1 THEN amount ELSE 0 END) AS januari,
SUM(CASE WHEN month_in = 2 THEN amount ELSE 0 END) AS februari,
SUM(CASE WHEN month_in = 3 THEN amount ELSE 0 END) AS maret
FROM yourTable
GROUP BY
item_id
ORDER BY
item_id;
You almost got it. This is the simplest solution, without extra hassle:
SELECT
item_id,
SUM(CASE WHEN month_in = 1 THEN amount ELSE 0 END) AS januari,
SUM(CASE WHEN month_in = 2 THEN amount ELSE 0 END) AS februari,
SUM(CASE WHEN month_in = 3 THEN amount ELSE 0 END) AS maret
from table
group by item_id
order by item_id asc
You don't need to define the months as a separate rowset, because the months are defined as values 1, 2, 3, ... as columns. Similarly, the items are defined by the group by function.

SQL group and condition sum in the last row

I have several items which belongs to different group, some are unknown group.
I need the sum of each group by date.
I just try below SQL but still not exactly what I want:
with A as (
SELECT PG, EMANAGER_DATE,
CASE WHEN (EMANAGER_DATE = '2021-09') THEN SUM(NET_VALUE_USD) ELSE 0 END AS "2021-09",
CASE WHEN (EMANAGER_DATE = '2021-10') THEN SUM(NET_VALUE_USD) ELSE 0 END AS "2021-10",
CASE WHEN (EMANAGER_DATE = '2021-11') THEN SUM(NET_VALUE_USD) ELSE 0 END AS "2021-11",
CASE WHEN (EMANAGER_DATE = '2021-12') THEN SUM(NET_VALUE_USD) ELSE 0 END AS "2021-12"
FROM table1
GROUP BY PG, EMANAGER_DATE
)
select PG, max("2021-09") AS "2021-09", max("2021-10") AS "2021-10", max("2021-11") AS "2021-11", max("2021-12") AS "2021-12" from A GROUP BY PG
DB: SAP HANA
Data:

You can adjust your query and use GROUPING SETS:
SELECT (CASE WHEN GROUPING(PG) = 1 THEN 'Total' ELSE PG END) as PG,
SUM(CASE WHEN EMANAGER_DATE = '2021-09' THEN NET_VALUE_USD ELSE 0 END) AS "2021-09",
SUM(CASE WHEN EMANAGER_DATE = '2021-10' THEN NET_VALUE_USD ELSE 0 END) AS "2021-10",
SUM(CASE WHEN EMANAGER_DATE = '2021-11' THEN NET_VALUE_USD ELSE 0 END) AS "2021-11",
SUM(CASE WHEN EMANAGER_DATE = '2021-12' THEN NET_VALUE_USD ELSE 0 END) AS "2021-12"
FROM _SYS_BIC."APP_SCM/ZCV_APP_SCM_CTOS_PARENT_UNCONFIRMED_BACKLOG_P"
GROUP BY GROUPING SETS ( (PG), () );

How to modify a SQL SELECT request with GROUP BY

I'm using the following SQL request to Informix DB:
select fromQ, toQ, count(callid) as cont_num, type
from some_table
group by fromQ, toQ, type
order by fromQ, toQ;
It produces the result:
fromq toq cont_num type
-----------------------------------
Sales 12 1
English 1 1
MB 59 1
Reception 3 2
Reception 53 1
Service 1 1
MB Sales 1 1
MB English 1 1
This is OK, as expected. Please note there are 2 rows for toq=Reception.
Field WRTYPE can have values only from 1 to 3.
So idea is to make an output like this:
fromq toq cont_num type1 type2 type3
------------------------------------------------
Sales 12 12 0 0
English 1 1 0 0
MB 59 59 0 0
Reception 56 53 3 0
Service 1 1 0 0
MB Sales 1 1 0 0
MB English 1 1 0 0
Is there a simple way to do this?
Use conditional aggregation:
select fromQ, toQ, count(callid) as cont_num,
sum(case when type = 1 then 1 else 0 end) as type_1,
sum(case when type = 2 then 1 else 0 end) as type_2,
sum(case when type = 3 then 1 else 0 end) as type_3
from some_table
group by fromQ, toQ
order by fromQ, toQ;

Firebird 3 SQL windows function over()

I need help..
I have table orders like this
id,order_date,price,customer_id
1 01.01.2001 100 1
2 01.02.2001 0 1
3 20.02.2001 0 1
4 04.04.2001 200 1
I need select result like this
id,order_date,price,customer_id,somefield
1 01.01.2001 100 1 100
2 01.02.2001 0 1 100
3 20.02.2001 0 1 100
3 04.04.2001 200 1 200
Try sql like this
select a.id,order_date,
coalesce(a.price,0) price,
customer_id
sum(coalesce(a.price,0)) OVER (order by a.order_date) somefield,
from tb_orders a
where a.customer_id=4583 and a.orderstate = 1
order by a.order_date
but result gives this
id,order_date,price,customer_id,somefield
1 01.01.2001 100 1 100
2 01.02.2001 0 1 100
3 20.02.2001 0 1 100
3 04.04.2001 200 1 300
You could create subgroup:
SELECT *, MAX(price) OVER(PARTITION BY grp) AS somefield
FROM (
select a.id,order_date,
coalesce(a.price,0) price,
customer_id,
sum(CASE WHEN price = 0 THEN 0 ELSE 1 END) OVER (order by a.order_date) grp
from tb_orders a
where a.customer_id=4583
and a.orderstate = 1
) sub
order by order_date;

SQL Calculations based by field type and group by the type

Database includes FamID, TicketType and Amt
I want to get a calculation for total amount for each tickettype for each family and sort by family high to low based on total for all tickettypes.
Database values are:
FamID TicketType Amt
1 1 10
1 1 10
1 2 20
1 3 30
2 2 20
2 1 10
2 1 10
2 1 10
2 3 30
3 3 30
3 3 30
3 3 30
Would like results to be
Family Type 1 Type 2 Type 3 Total
3 0 0 90 90
2 30 20 30 80
1 20 20 30 70
Am I trying to do too much?
You never specified your RDBMS, but the following pivot query should work across most major ones with little modification:
SELECT t.`Type 1`, t.`Type 2`, t.`Type 3`,
(t.`Type 1` + t.`Type 2` + 2*t.`Type 3`) AS Total
FROM
(
SELECT FamID AS Family,
SUM(CASE WHEN TicketType = 1 THEN Amt ELSE 0 END) AS `Type 1`,
SUM(CASE WHEN TicketType = 2 THEN Amt ELSE 0 END) AS `Type 2`,
SUM(CASE WHEN TicketType = 3 THEN Amt ELSE 0 END) AS `Type 3`,
FROM Tickets
GROUP BY FamID
) t
ORDER BY t.Total DESC
