SQLite: Group records with nearest integer field - sql

There is a table with integer field. I need to write a query which returns groups with the following condition: min value of the field in the some group differs more than N to max value in the next group.
Example with N=10.
SQL query for the table
01 A A 1
02 A B 9
03 B B 11
04 B C 22
05 C C 29
should return
01 A A 1 0
02 A B 9 0
03 B B 11 0
04 B C 22 1
05 C C 29 1
Here is a similar question for Python. How to do this in SQLite?

Deleting values on Hana Table based on a field value

I am working on a hana table and i am trying to delete a table if it contains value from a list.
A B
22 01
22 01
22 02
22 06
23 01
23 01
23 06
I will like to drop some values from this table and have this.
A B
22 01
22 01
22 06
23 01
23 01
23 06
Basically i will like to most likely do a count and check if column B consists of 01 AND 02, if it does drop 02 and if it consists of only 01 leave as it is.
This seems virtually impossible with almost every sql script i have tried
SELECT BP, COUNT(*) AS SO FROM "EH"."BP_CUST" GROUP BY BP;
This scripts gets the count of each row and put it in SO column.
after that maybe do an if statement on the SO column and delete if the B field contains 01 and 02?
I tried doing and IF statement then select and i could not get it to work either.
A B
22 01
22 01
22 02
22 06
23 01
23 01
23 06
24 02
Becomes
A B
22 01
22 01
22 06
23 01
23 01
23 06
24 02
If I understand correctly, you want:
select c.*
from "EH"."BP_CUST" c
where c.b <> '02' or
not exists (select 1
from "EH"."BP_CUST" c2
where c2.a = c.a and c2.b = '01'
);
Your question says "delete". But I think the intention is to select "02" rows only when there is no "01" row for the same a (and all other rows).
If I understood correctly, this might be the solution:
DELETE BP_CUST
WHERE A IN
(
SELECT
BP_CUST.A
FROM
(
SELECT
A
, COUNT(CASE WHEN B != '02' THEN 1 ELSE NULL END) AS NOT_02
, COUNT(CASE WHEN B = '02' THEN 1 ELSE NULL END) AS IS_02
FROM BP_CUST
GROUP BY A
) AS t_delete
JOIN BP_CUST ON BP_CUST.A = t_delete.A
WHERE B = '02' AND NOT_02 > 0 AND IS_02 > 0
)
AND B = '02'

I have set of jobs record for whole month and want to display qty of jobs date wise in SQL

We have thousands of record in our data and want to count date wise jobs with category through single query. It is Possible?
Display required as under
TypesJobs 01 02 03 04 05 06 07
A 2 1 6 4 1 3 4
B 10 12 8 10 12 9 13
C 3 5 4 3 2 5 4
Here Types of jobs count for a day in date column 01, 02, 03 are date range of the month
You can use conditional aggregation, something like this:
select typesjobs,
sum(case when month(datecol) = 1 then 1 els e0 end) as month_01,
sum(case when month(datecol) = 2 then 1 els e0 end) as month_02,
. . .
from t
where <date condition here>
group by typesjobs;

Adding rows, running count, running sum to query results

I have a table with the following ddl.
CREATE TABLE "LEDGER"
("FY" NUMBER,
"FP" VARCHAR2(20 BYTE),
"FUND" VARCHAR2(20 BYTE),
"TYPE" VARCHAR2(2 BYTE),
"AMT" NUMBER
)
The table contains the following data.
REM INSERTING into LEDGER
SET DEFINE OFF;
Insert into LEDGER (FY,FP,FUND,TYPE,AMT) values (15,'03','A','03',1);
Insert into LEDGER (FY,FP,FUND,TYPE,AMT) values (15,'04','A','03',2);
Insert into LEDGER (FY,FP,FUND,TYPE,AMT) values (16,'04','A','03',3);
Insert into LEDGER (FY,FP,FUND,TYPE,AMT) values (12,'05','A','04',6);
based on the partition of fy,fp,fund and type I would like to write a query to keep a running count from the beginning of fp(fp though it is a varchar it represents a number in the month. i.E 2 equals february and 3 equals march etc.) to a hard number of 14. So taking a closer look at the data you will notice that in FY 15 the max period is 04 so i must add another 10 periods to my report to get my report to have the full 14 periods. here is the expected output.
here is what i tried, but I'm just simply stumbling all together on this.
WITH fy_range AS
(
SELECT MIN (fy) AS min_fy
, MAX (fy) AS max_fy
FROM ledger
),all_fys AS
(
SELECT min_fy + LEVEL - 1 AS fy
FROM fy_range
CONNECT BY LEVEL <= max_fy + 1 - min_fy
)
,all_fps AS
(
SELECT TO_CHAR (LEVEL, 'FM00') AS fp
FROM dual
CONNECT BY LEVEL <= 14
)
SELECT
FUND
,G.TYPE
,G.FY
,G.FP
,LAST_VALUE(G.AMT ignore nulls) OVER (PARTITION BY G.FUND ORDER BY Y.FY P.FP ) AS AMT
FROM all_fys y
CROSS JOIN all_fps p
LEFT OUTER JOIN LEDGER G PARTITION BY(FUND)
ON g.fy = y.fy
AND g.fp = p.fp;
but I end up with a bunch of nulls and some strange results.
This may not be the most efficient solution, but it is easy to understand and maintain. First (in the most deeply nested subquery) we find the min FP for each combination of FY, FUND and TYPE. Then we use a CONNECT BY query to fill all the FP for all FY, FUND, TYPE combinations (up to the hard upper limit of 14). Then we left-outer-join to the original data in the LEDGER table. So far we densified the data. In the final query (the join) we also add the column for the cumulative sum - that part is easy after we densified the data.
TYPE is an Oracle keyword, so it is probably best not to use it as a column name. It is also best not to use double-quoted table and column names (I had to use upper case everywhere because of that). I also made sure to convert from varchar2 to number and back to varchar2 - we shouldn't rely on implicit conversions.
select S.FY, to_char(S.FP, 'FM09') as FP, S.FUND, S.TYPE,
sum(L.AMT) over (partition by S.FY, S.FUND, S.TYPE order by S.FP) as CUMULATIVE_AMT
from (
select FY, MIN_FP + level - 1 as FP, FUND, TYPE
from (
select FY, min(to_number(FP)) as MIN_FP, FUND, TYPE
from LEDGER
group by FY, FUND, TYPE
)
connect by level <= 15 - MIN_FP
and prior FY = FY
and prior FUND = FUND
and prior TYPE = TYPE
and prior sys_guid() is not null
) S left outer join LEDGER L
on S.FY = L.FY and S.FP = L.FP and S.FUND = L.FUND and S.TYPE = L.TYPE
;
Output:
FY FP FUND TYPE CUMULATIVE_AMT

How do I add specific values from one different table to columns in a row based off of values in another table?

In SQL Server I have 2 tables that looks like this:
TEST SCRIPT 'a collection of test scripts'
(PK)
ID Description Count
------------------------
A12 Proj/Num/Dev 12
B34 Gone/Tri/Tel 43
C56 Geff/Ben/Dan 03
SCRIPT HISTORY 'the history of the aforementioned scripts'
(FK) (PK)
ScriptID ID Machine Date Time Passes
----------------------------------
A12 01 DEV012 6/26/15 16:54 4
A12 02 DEV596 6/28/15 13:12 9
A12 03 COM199 3/12/14 14:22 10
B34 04 COM199 6/30/13 15:45 12
B34 05 DEV012 6/30/15 13:13 14
B34 06 DEV444 6/12/15 11:14 14
C56 07 COM321 6/29/14 02:19 12
C56 08 ANS042 6/24/14 20:10 18
C56 09 COM432 6/30/15 12:24 4
C56 10 DEV444 4/20/12 23:55 2
In a single query, how would I write a select statement that takes just one entry for each DISTINCT script in TEST SCRIPT and pairs it with the values in only the TOP 1 most recent run time in SCRIPT HISTORY?
For example, the solution to the example tables above would be:
OUTPUT
ScriptID ID Machine Date Time Passes
---------------------------------------------------
A12 02 DEV596 6/28/15 13:12 9
B34 05 DEV012 6/30/15 13:13 14
C56 09 COM432 6/30/15 12:24 4
The way you describe the problem is almost directly as cross apply:
select h.*
from testscript ts cross apply
(select top 1 h.*
from history h
where h.scriptid = ts.id
order by h.date desc, h.time desc
) h;
Please try something like this:
select *
from SCRIPT SCR
left join (select MAX(SCRIPT_HISTORY.Date) as Date, SCRIPT_HISTORY.ScriptID
from SCRIPT_HISTORY
group by SCRIPT_HISTORY.ScriptID
) SH on SCR.ID = SH.ScriptID

SQL: how to select IDs according to a condition?

I just started to program in SQL and I have a bit of a problem (n.b., I am working of a tabl that come from a game). My table is something like this, where ID refers to a single person, H to a certain hour of playing and IF to a certain condition:
ID H IF
01 1 0
01 2 0
01 3 0
02 1 0
02 2 1
03 1 0
03 2 1
03 3 0
03 4 1
In this case player 01 played for three hours, player 02 for two hours and player 03 for four hours. In each of these hours they may or may have not performed an action. If they did, a 1 appears in the IF column.
Now, my doubt is: how can I query so that I have a table with only the ID of the people who never performed the action? I do not want to rule out only the row with IF = 1, I want to rule out all the row with that ID. In this case it should become:
01 1 0
01 2 0
01 3 0
Any help?
This should do it.
select *
from table
where Id not in (select Id from table where IF = 1)
SELECT ID FROM Table GROUP BY ID HAVING SUM(IF)=0
