I'm finding a way to group SQL query by trimester. I have found a way to do it using MySQL on this link.
This is what I'm expecting:
Range Start Range End Count
----------- ---------- -----
2013-09-01 2013-11-26 87
2013-06-01 2013-08-31 92
2013-03-01 2013-05-31 92
2012-12-01 2013-02-28 90
2012-09-01 2012-11-30 91
This is what I have tried:
SELECT MIN(start_date) AS Range_Start, MAX(start_date) AS Range_End, COUNT(ID) AS Total
FROM [dbo].[table]
GROUP BY FLOOR(DATEDIFF(MONTH, DATEADD(DAY, -DAY(start_date)+1, start_date), DATEADD(DAY, -DAY(start_date)+1,getdate())) /3)
ORDER BY 1 ASC
This is what I get:
Range Start Range End Count
----------- ---------- -----
1900-01-01 00:00:00.000 1900-01-01 00:00:00.000 8

You can use apply:
select p.*, w.*
from port p outer apply
(select top (1) w.*
from weights w
where w.utcDT <= p.utcDT
order by w.utcDT desc
) w;
outer apply is usually pretty efficient, if you have the right indexes. In this case, the right inex is on weights(utcDT desc).
You can use lead() in a subquery to associate the next date a weight changes to each weights record, and then join with port using an inequality condition on the dates:
select p.utcDt, w.weight
from port p
inner join (
select utcDt, weight, lead(utcDt) over(order by utcDt) lead_utcDt from weights
) w
on p.utcDt >= w.utcDt
and (w.lead_utcDt is null or p.utcDt < w.lead_utcDt)
I have a temp table
BusinessDate SSQ_CompScore

I need to calculate delta for each current date.
I have prepared a solution but it doesn't work where date as not consecutive.
Can you please help?
select t1.businessdate, t1.ssq_compscore, (t2.ssq_compscore - t1.ssq_compscore) as delta
from #temp t1
left join #temp t2 on t1.businessdate = DATEADD(dd,1,t2.businessdate)
where t1.businessdate >='20180814'
Result set should be as
BusinessDate SSQ_CompScore Delta
2011-01-05 00:00:00.000 41 NULL
2011-01-06 00:00:00.000 6 35
2011-01-07 00:00:00.000 1 5
2011-01-10 00:00:00.000 8 7
2011-01-11 00:00:00.000 48 40
2011-01-12 00:00:00.000 50 2
2011-01-13 00:00:00.000 59 9
Not sure if this is the most efficient way but it works as far as I see
SELECT businessdate, SSQ_CompScore ,
SSQ_CompScore - (SELECT SSQ_CompScore
FROM temp
WHERE businessdate < t1.businessdate
ORDER BY businessdate DESC
LIMIT 1) as delta
FROM temp t1
ORDER BY businessdate ASC
I have the following SQL Server query problem.
If there is a row where Issue_DATE = as Maturity_Date in another row, and if both rows have the same ID and Amount USD, then none of these rows should be displayed.
Here is a simplified version of my table:
ID ISSUE_DATE MATURITY_DATE AMOUNT_USD
1 2010-01-01 00:00:00.000 2015-12-01 00:00:00.000 5000
1 2010-01-01 00:00:00.000 2001-09-19 00:00:00.000 700
2 2014-04-09 00:00:00.000 2019-04-09 00:00:00.000 400
1 2015-12-01 00:00:00.000 2016-12-31 00:00:00.000 5000
5 2015-02-24 00:00:00.000 2015-02-24 00:00:00.000 8000
4 2012-11-29 00:00:00.000 2015-11-29 00:00:00.000 10000
3 2015-01-21 00:00:00.000 2018-01-21 00:00:00.000 17500

1 2015-01-12 00:00:00.000 2018-01-12 00:00:00.000 18000
2 2015-12-05 00:00:00.000 2016-01-10 00:00:00.000 12000
Result should be:
ID ISSUE_DATE MATURITY_DATE AMOUNT_USD
1 2010-01-01 00:00:00.000 2001-09-19 00:00:00.000 700

I tried with self join, but I do not get right result.
Thanks in advance!
Can you try something like this? 'not exists' is the way of doing it.
select * from table t1 where not exists (select 'x' from table t2 where t1.issue_date = t2.maturity_date and t1.amount_usd=t2.amount_usd and t1.id = t2.id)
I'd think about making subquery of all the dupes and then eliminating them from the first table like so:
select t1.ID
, t1.ISSUE_DATE
, t1.MATURITY_DATE
, t1.AMOUNT_USD
FROM
t1
LEFT JOIN
(select a.ID
, a.ISSUE_DATE
, a.MATURITY_DATE
, a.AMOUNT_USD
FROM
t1 a
INNER JOIN
ti b
) dupes
on
t1.ID = dupes.ID
WHERE dupes.ID IS NULL;
There is a table test that contains data as shown below:
id id1 id2 id3 date1
1 1 2 2500 2010-09-30 00:00:00.000
2 1 2 4700 2005-01-01 00:00:00.000
3 1 2 4700 2009-08-01 00:00:00.000
4 1 3 2500 2010-09-30 00:00:00.000
5 1 3 4700 2003-02-01 00:00:00.000
6 1 8 4000 2007-04-01 00:00:00.000
7 1 8 4000 2013-09-01 00:00:00.000
8 1 8 4060 2007-04-01 00:00:00.000
9 1 8 8500 2010-09-30 00:00:00.000
What I need to do is order this data in the following format:
id1 id2 id3 date1 date2
1 2 2500 2010-09-30 00:00:00.000 9999-12-31 23:59:59.997
1 2 4700 2005-01-01 00:00:00.000 2009-07-31 00:00:00.000
1 2 4700 2009-08-01 00:00:00.000 9999-12-31 23:59:59.997
1 3 2500 2010-09-30 00:00:00.000 9999-12-31 23:59:59.997
1 3 4700 2003-02-01 00:00:00.000 9999-12-31 23:59:59.997
1 8 4000 2007-04-01 00:00:00.000 2013-08-31 00:00:00.000
1 8 4000 2013-09-01 00:00:00.000 9999-12-31 23:59:59.997
1 8 4060 2007-04-01 00:00:00.000 9999-12-31 23:59:59.997
1 8 8500 2010-09-30 00:00:00.000 9999-12-31 23:59:59.997
Using the following logic:
If there is only one record for the same id1, id2 and id3 we use the original date for date1 and we use the maximum date available in sql server (9999-12-31) for date2.
If there is more than one record for the same id1, id2 and id3 we still keep the original date for date1 and we use for date2 the original date field minus 1 day from the next record . The last record will use also the maximum date available in sql server (9999-12-31) for date2.
I manage to build the following query but it is not perfect as it brings some invalid records:
select * from
(select
t1.id1,t1.id2,t1.id3,t1.date1,
case
when t1.date1=t2.date1 then CONVERT(DATETIME, '12/31/9999 23:59:59.997')
else DATEADD(day, -1, t2.date1)
end as date2
from test t1
inner join test t2
on t1.id1=t2.id1 and t1.id2=t2.id2 and t1.id3=t2.id3
) sub
where date2>=date1
order by id1,id2,id3,date1 asc
The result of the query is:
id1 id2 id3 date1 date2
1 2 2500 2010-09-30 00:00:00.000 9999-12-31 23:59:59.997
1 2 4700 2005-01-01 00:00:00.000 9999-12-31 23:59:59.997 *
1 2 4700 2005-01-01 00:00:00.000 2009-07-31 00:00:00.000
1 2 4700 2009-08-01 00:00:00.000 9999-12-31 23:59:59.997
1 3 2500 2010-09-30 00:00:00.000 9999-12-31 23:59:59.997
1 3 4700 2003-02-01 00:00:00.000 9999-12-31 23:59:59.997
1 8 4000 2007-04-01 00:00:00.000 9999-12-31 23:59:59.997 *
1 8 4000 2007-04-01 00:00:00.000 2013-08-31 00:00:00.000
1 8 4000 2013-09-01 00:00:00.000 9999-12-31 23:59:59.997
1 8 4060 2007-04-01 00:00:00.000 9999-12-31 23:59:59.997
1 8 8500 2010-09-30 00:00:00.000 9999-12-31 23:59:59.997
As you can see, the records marked with * are not necessary but I don't know how to get rid off that rows.
This should do:
select id1,id2,id3, date1,
isnull(lead(date1) over(partition by id1,id2,id3 order by date1)-1, '99991231') as date2
from test
Try something like this
SELECT t1.id1, t1.id2, t1.id3, t1.date1 as date1,
ISNULL(t2.date1, CONVERT(DATETIME, '12/31/9999 23:59:59.997')) as date2
FROM test t1
LEFT JOIN test t2 ON t1.id1 = t2.id1 AND t1.id2 = t2.id2 AND t1.id3 = t2.id3
AND t1.id < t2.id
ORDER BY t1.id1, t1.id2, t1.id3, date1, date2

I need to take the value for the quarter and multiply it buy all the days in the quarter by the daily value
You could try:
SELECT dt.day, dt.factor*mt.factor AS daily_factor
FROM daily_table dt INNER JOIN month_table mt
ON YEAR(dt.day) = YEAR(mt.day)
AND FLOOR((MONTH(dt.day)-1)/3) = FLOOR((MONTH(mt.day)-1)/3)
ORDER BY dt.day
or (as suggested by #Andriy)
SELECT dt.day, dt.factor*mt.factor AS daily_factor
FROM daily_table dt INNER JOIN month_table mt
ON YEAR(dt.day) = YEAR(mt.day)
AND DATEPART(QUARTER, dt.day) = DATEPART(QUARTER, mt.day)
ORDER BY dt.day
