Query - perhaps GROUP BY

Hi,
Using SQL Server 2000
I have a table like this
Results
ResultID int primary key
ProductID char(10)
RetailerID int
RetailerPrice money
Some sample data might be
ResultID ProductID RetailerID RetailerPrice
1 1231231234 1 9.99
2 1231231234 2 19.99
3 1231231234 3 12.99
4 1231231235 1 11.99
5 1231231235 2 13.99
6 1231231235 3 3.99
I want to return the lowest price and it's resultid for a list of products.
I've got as far as
SELECT ProductID, MIN(RetailerPrice)
FROM Results
WHERE ProductID IN('1231231234', '1231231235')
GROUP BY ProductID
which returns
ProductID RetailerPrice
1231231235 3.99
1231231234 9.99
What I want is
ProductID RetailerPrice ResultID
1231231235 3.99 6
1231231234 9.99 1
I've tried
SELECT ProductID, MIN(RetailerPrice), ResultID
FROM Results
WHERE ProductID IN('1231231234', '1231231235')
GROUP BY ProductID, ResultID
but this returns every price for each product. I've tried various group by
clauses but have hit a brick wall. If anyone can point me in the right
direction I'd appreciate it.
Cheers,
JonLooks like a derived table:
SELECT
R.*
FROM
Results R
JOIN
(
SELECT ProductID, MIN(RetailerPrice) AS RetailerPrice
FROM Results
GROUP BY ProductID
) AS X ON X.ProductID = R.ProductID
AND X.RetailerPrice = R.RetailerPrice

Imagine we have 2 tables
personal table with 3 fields:
personalid int
jobid int
oldjobid int

and table job with 2 fields :
jobid int
jobname varchar

now I want write a query with this result :
personalid,jobname,oldjobname
which jobname means the name in job table related with jobid in personal table
and oldjobname means the name in job table related with oldjobid in personal table
please help me

SELECT
personalid,
jobname,
(SELECT jobname FROM job INNER JOIN personal on personal.oldjobid=job.jobid) AS Oldjobname
FROM
personal
INNER JOIN job ON personal.jobid = job.jobid
|||

tanks for you answer
but when I run this query this error occure:
"subquery returned more than 1 value. This is not permitted when the subquery follows =,!=,<,<=,<,<= or when the subquery is used as an expression"

|||Try this:
SELECT personalid, j1.jobName, j2.jobName as oldJobName
FROM personal p
INNER JOIN job j1 ON p.jobID = j1.jobID
INNER JOIN job j2 ON p.oldJobID = j2.jobID

Hi,

objSqlCmd.Parameters.Add("@.Cnt", SqlDbType.Int).Direction = ParameterDirection.Output

What is the meaning of .(dot) direction. and ParameterDirection.Output

Thanking you

Abdul

SqlParameter.Direction property: Gets or sets a value that indicates whether the parameter is input-only, output-only, bidirectional, or a stored procedure return value parameter (from MSDN).

ParameterDirection: To set the value of Direction property.

query

drop table share
create table share
(
shid int identity ,
dt datetime,
price int
)
insert into share(dt,price) values('1-jan-2006',10)
insert into share(dt,price) values('2-jan-2006',11)
insert into share(dt,price) values('6-jan-2006',15)
insert into share(dt,price) values('4-jan-2006',9)
select * from share
output i want is
the difference in share prices from the previous day.
so
1 (11-10)
4 (15-11)
-6 (9-15)
select top 100 percent p1.shid p1shid, p2.shid p2shid, p1.price p1price,
p2.price p2price
from
(select * from share
) as p2,
share p1
where p1.shid < p2.shid
order by p1.shid, p2.shid
thisis the closest i could come up with but it has duplicates.Try,
select b.price - a.price
from t1 as a inner join t1 as b
on a.dt = (select max(c.dt) from t1 as c where c.dt < b.dt)
Why 15 - 11 and 9 - 15 instead 9 - 11 and 15 - 9?. If you meant previous
[shid] then try:
select b.price - a.price
from t1 as a inner join t1 as b
on a.shid = (select max(c.shid) from t1 as c where c.shid < b.shid)

Quaterly Data selection problem

Hi all,

I have one table with oper_year and oper_month , those two are int.
Now i want to take the quaterly data from the table as per the user selection like this
If user selects...200001 to 200212 means in that we have 8 quaters...4 in 2001 and 4 in 2002 and if user selects the range from 200101 to 200209 it has 7 quaters..means in 2001..4 Quaters.. and in 2002 --3 Quaters...
i have the following query it is working but if i give the 200101 to 200209 it is shows only 6 quaters...what is the wrong in that if possible please correct it....

SELECT CASE WHEN (oper_month) IN (1,2,3)THEN 'Q1-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (4,5,6)THEN 'Q2-' + Cast(oper_year as varchar)
WHEN(oper_month) IN (7,8,9)THEN 'Q3-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (10,11,12)THEN 'Q4-'+ Cast(oper_year as varchar)END
,sum(amount)
FROM oper_sundata
where oper_year between 2001 and 2002
and oper_month between 01 and 09
group by oper_year,
CASE WHEN (oper_month) IN (1,2,3)THEN 'Q1-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (4,5,6)THEN 'Q2-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (7,8,9)THEN 'Q3-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (10,11,12)THEN 'Q4-' + Cast(oper_year as varchar)End
order by oper_year,
CASE WHEN (oper_month) IN (1,2,3)THEN 'Q1-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (4,5,6)THEN 'Q2-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (7,8,9)THEN 'Q3-' + Cast(oper_year as varchar)
WHEN (oper_month) IN (10,11,12)THEN 'Q4-' + Cast(oper_year as varchar)End

thanksyou have asked this quarterly question three times now

received answers twice but have not replied whether the answers you already received were suitable

here is another answer

please, please let us know if this is suitable, don't just ignore us, or your future questions will go unanswered

this is my original answer, modified by ionut (http://dbforums.com/member.php?action=getinfo&userid=26346), then modified by me to add date range testing
select 'Q' + cast(cast( (month(period)+2) / 3 as integer ) as char(1))
+ '-' + year(period) as QuarterYear
, sum(amount) as SumAmount
from oper_sundata
where year(period)*12+month
between cast(@.startyyyymm as integer)
and cast(@.endyyyymm as integer)
group
by cast( (month(period)+2) / 3 as integer )
, year(period)
order
by cast( (month(period)+2) / 3 as integer )
, year(period)
