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
Date Price
2015-05-01 00:00:00.000 34.25
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
Com C
Date Price
2015-05-12 00:00:00.000 34.29
2015-05-13 00:00:00.000 24.50
2015-05-14 00:00:00.000 76.21
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

2015-05-14 00:00:00.000 C 76.21
2015-05-15 00:00:00.000 C 36.70
2015-05-16 00:00:00.000 C 48.20
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 Want to combine all rows of the same client if it is in the same range of the rows with the same clientnumber above. Where the beginningdate is the lowest and enddate the highest. This also has to account for None values and clients with only one row.
so outcome would be something like:
clientnummer begindatum einddatum

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 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 2015-12-05 00:00:00.000 2016-01-10 00:00:00.000 12000
Result should be:

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;

How can I do this?
Select *

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

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)
