I'm new in SQL and I this for my uni project. I have a table with columns Rego, FirstRego, LastRego, RegoDue.
Suppose I have the following data:
Rego FirstRego LastRego RegoDue
YGF 615 2011-04-07 00:00:00.000 2011-04-07 00:00:00.000 2012-04-07 00:00:00.000
YGF 615 2011-04-07 00:00:00.000 2012-04-07 00:00:00.000 2013-04-07 00:00:00.000

ZSU 823 2012-04-30 00:00:00.000 2012-04-30 00:00:00.000 2013-04-30 00:00:00.000
In the query output I want the Rego to be once with the highest RegoDue i.e the output should look like:
Rego FirstRego LastRego RegoDue
YGF 615 2011-04-07 00:00:00.000 2012-04-07 00:00:00.000 2013-04-07 00:00:00.000

ZJT 795 2012-10-31 00:00:00.000 2012-10-31 00:00:00.000 2013-10-31 00:00:00.000

How can I do this?
Select *
From Tbl T1
Where RegoDue =
(
Select Max(RegoDue)
From Tbl T2
Where T2.Rego = T1.Rego
)
Firstly you want to find the latest rego due date. Once you have this you can join on it to filter out the undesired results.
select
t.Rego, t.FirstRego, t.LastRego, lr.LatestRegoDue as RegoDue
from Table1 t
join
(
select
Rego, max(RegoDue) as LatestRegoDue
from Table1
group by Rego
) lr on t.Rego = lr.Rego and t.RegoDue = lr.LatestRegoDue

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 sql query that brings back a list of references (products) that were at a specific status and an effective date. Unfortunately when one product moves to a different status the system doesn't put an end date in, so I am wanting to generate the end date, based on the effective date and sequence number. Is this possible?
Product Status EffectiveDate Enddate SeqNo
10 *UC 2017-10-02 00:00:00.000 NULL 8590

SO I would want to return the following...

Many thanks.
You can use lead() :
select t.*, lead(EffectiveDate) over (partition by product order by SeqNo) as EndDate
from table t;
However, lead() starts from version 2012 +, so you can use apply instead :
select t.*, t1.EffectiveDate as EndDate
from table t outer apply
(select top (1) t1.*
from table t1
where t1.product = t.product and t1.SeqNo > t.SeqNo
order by t1.SeqNo
) t1;
Say, I have 6 temp tables stored as the following (those 3 are samples) and I would to form them into 1 single table, to be in series (headers Date, Com, Price).
Com A

2015-05-02 00:00:00.000 35.20
2015-05-03 00:00:00.000 36.70
2015-05-04 00:00:00.000 32.37
2015-05-05 00:00:00.000 32.40
2015-05-06 00:00:00.000 32.20
Com B
Date Price
2015-05-07 00:00:00.000 54.29
2015-05-08 00:00:00.000 54.50
2015-05-09 00:00:00.000 56.21
2015-05-10 00:00:00.000 56.70
2015-05-11 00:00:00.000 58.20

2015-05-15 00:00:00.000 36.70
2015-05-16 00:00:00.000 48.20
The output to look like, and I would like to store it as another temp table for merging later:
Date Com Price
2015-05-01 00:00:00.000 A 34.25
2015-05-02 00:00:00.000 A 35.20

Seems like a simple union all to me:
SELECT [Date], 'A' as Com, Price
FROM [Com A]
UNION ALL
SELECT [Date], 'B' as Com, Price
FROM [Com B]
UNION ALL
SELECT [Date], 'C' as Com, Price
FROM [Com C]
Based on your sample data
Select Date,'A' AS Com,Price from [COM A]
UNION ALL
Select Date,'B' AS Com,Price from [COM B]
UNION ALL
Select Date,'C' AS Com,Price from [COM C]
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
2 2015-02-02 00:00:00.000 2015-12-05 00:00:00.000 12000
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

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
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;
I have daily values in one table and monthly values in another table. I need to use the values of the monthly table and calculate them on a daily basis.
basically, monthly factor * daily factor -- for each day

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
