i have two tables: Pictures and UserComments, both have PictureID column
in second table i store each comment made by users at a specific picture like so: CommentID, UserName, PictureID, Comment, Date
i am trying to make a stored procedure with @UserName input parameter witch returns Distinct Pictures whereon that user has commented (sorry for that whereon expression, is from dictionary and i don't know if it express what i want to mean) SELECT Pictures.OwnerName AS 'Owner', Pictures.Name AS 'Name of picture', COUNT(UserComments.PictureID) AS 'Comments made', Pictures.Image1
FROM Pictures INNER JOIN
UserComments ON Pictures.PictureID = UserComments.PictureID
WHERE (UserComments.UserName = @UserName)
GROUP BY UserComments.UserName, Pictures.Name, Pictures.OwnerName, Pictures.Image1
if i use this statement it shows me the picture details whereon that user has commented and if he commented more than once on the same picture the result isn't duplicated
but with that statement i can't order by UserComments.Date because i have to use GROUP BY UserComments.Date and the results will not be shown in pairs
How can i order the results by Date Desc?
sorry for my bad english, if you don't understand please tell me and i'll try to explain by examples
please help me, thanks
Hello!
This is my query:SELECT tblMessages.id, tblMessages.txtIngress, tblMessages.strSubject, tblMessages.txtMessage, tblMessages.postedBy, tblMessages.datePosted,
tblMessages.intMessGroup
FROM tblMessages INNER JOIN
tblUsersToGroups ON tblMessages.intMessGroup = tblUsersToGroups.belongsToGroup INNER JOIN
tblUsers ON tblUsersToGroups.userId = tblUsers.id
WHERE (tblUsers.userName = @strUserName)
GROUP BY tblMessages.intMessGroup, tblMessages.id, tblMessages.txtIngress, tblMessages.strSubject, tblMessages.txtMessage, tblMessages.postedBy,
tblMessages.datePosted
ORDER BY tblMessages.intMessGroupWhat I want to do is select the top 3 from each intMessGroup. In other cases where I'd want to Group By a computed column I could have used Rank, but since the column intMessGroup contains static values (message group id's) there should be some easy peasy way to do this, or?Thanks beforehand for any and all replies!Cheers!/Eskil

I need to find the first 3 days that a product is scheduled in one of my
tables. It may be scheduled on 12 different days, but I only want the first 3.
So, based on some sample data and this thread:
http://www.dbforums.com/t1115304.html
I was able to come up with a query that does what I need.
However, I have no idea how it works. For one, what
is Count(*) counting in the query?
create table #tmpSched (
sched_date datetime,
product char(3)
)
insert into #tmpsched
select '1/1/2001', 'abc'
union all
select '1/2/2001','abc'
union all
select '1/3/2001','abc'
union all
select '1/1/2001', 'def'
union all
select '1/2/2001','def'
union all
select '1/1/2001', 'ghi'
union all
select '1/1/2001', 'jkl'
union all
select '1/2/2001','jkl'
union all
select '1/3/2001','jkl'
union all
select '1/4/2001','jkl'
SELECT a.SCHED_DATE, a.PRODUCT
FROM #tmpSched a
INNER JOIN #tmpSched b
ON a.product = b.product
AND a.sched_date > = b.sched_date
GROUP BY a.product, a.sched_date
HAVING COUNT(*) <= 3
order by a.product, a.sched_date
drop table #tmpsched
Any explanation would be appreciated.
EDIT: Wanted first 3, not last 3. Changed "a.sched_date < = b.sched_date" to a.sched_date > = b.sched_date

hi
i have a database that has multiple records under the same id (each time a record is updated, it's assigned a date_value), i'm wanting one row to be generated using the data from the most recent date_value field.
a sample of the database looks something like this:
ID date_value data1 24 march info11 25 march info2
my statement looks like this:select max(date_value), data from table_name where data is not null group by id
this seems to bring up the following error for all the fields not in the group by part of the code:Column 'COLUMN_NAME' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
what am i doing wrong?
TIA!
I have this query.
SELECT ForeignKey, MAX(Version) AS Latest_VersionFROM tblContentWHERE (Published = 'True')GROUP BY ForeignKeyORDER BY ForeignKey
It works perfectly just like it is above. It returns 20 records choosing the maximum value in the version column for each value in the ForeignKey column. Here is a sample of the result set.
ForeignKey Latest_Version
1 2
2 2
3 1
Then when I try to add other fields to the select and group by clauses I hit a problem. Here is the new query
SELECT ForeignKey, MAX(Version) AS Latest_Version, TitleFROM tblContentWHERE (Published = 'True')GROUP BY ForeignKey, TitleORDER BY ForeignKey
Now it is returning 22 records in the result set Here are the relevant records.
ForeignKey Latest_Version Title
1 1 Title1
1 2 Title2
2 1 Title3
2 2 Title4
3 1 Title5
I know it is necessary to add each column in the select clause to the group by clause but that seems make group by not work at all. Am I going about this the wrong way. Basically I want to return only the ForeignKey records that have the highest version. This table does have a foreign key relationship with another table. Should I be doing this with a join instead somehow?
Thanks, Laura

others 11

How can I match Table A 999 with the first occurrence of 999 in Table B, and then extract other field data (such as street address) from the Table B record. I have tried using the Count() function, but it seems that I can only do this using cursors.

Hello everyone, I've got a bit of an SQL mystery that I'm not sure how to solve. For some reason I just cant get my head around it. Here's the scenario:
Table A:
_____________
BidID - Int identity
AuctionID - int
BiderName - varchar(50)
bidAmount - money
______________________
Now obviously each Bid will have a Unique ID using BidID but the other rows will contain multiple bids per user, on many different items possibly.
BidID AuctionID BiderName BidAmount
1 4005 joeblow 100.00
2 4005 janedoe 101.00
3 4005 joeblow 107.00
4 4006 joeblow 100.00
5 4006 janedoe 105.00
6 4006 joeblow 106.00
I need to find out which Auctions JoeBlow is bidding on, but I dont need a table with Rows for every single one of his bids, just a distinct auctionID for his top bid so in this case the only thing returned would be
3 4005 joeblow 107.00
6 4006 joeblow 106.00
Any clues? I've been through sub querys, and stored procedures, and I cant get anything to work quite right.
Thanks in advance for your help.
Two tables: CompanyPrices(CompanyID, ProductID, Price), CompanyRegion(CompanyID, Region)
ProductID is the primary key.
I want to get 10 smallest prices in each Region. In other words, I am looking for 10 cheapest prices in each region. So, if there are 20 regions, I should get excatly 200 rows having prices for products from 200 companies if there were at least 10 companies in each region.
I tried the follwoing, but get incorrect results.
select S1.Region, S1.Price from (select CompanyPrices.*, Region from CompanyPrices inner join CompanyRegion on CompanyPrices.CompanyID=CompanyRegion.CompanyID) S1 inner join
(select CompanyPrices.*, Region from CompanyPrices inner join CompanyRegion on CompanyPrices.CompanyID=CompanyRegion.CompanyID) S2 on S1.Region = S2.Region
group by S1.Region, S1.Price having count(*)<=10 order by S1.Region, S1.Price
However, if I want to get 10 cheapest products for each company, the above sql works by modifying the join condition. Instead of S1.Region = S2.Region , I use S1.CompanyID = S2.CompanyID and I get correct results for 10 cheapest products for each company.
select S1.CompanyID, S1.Price from (select CompanyPrices.*, Region from CompanyPrices inner join CompanyRegion on CompanyPrices.CompanyID=CompanyRegion.CompanyID) S1 inner join
(select CompanyPrices.*, Region from CompanyPrices inner join CompanyRegion on CompanyPrices.CompanyID=CompanyRegion.CompanyID) S2 on S1.CompanyID = S2.CompanyID
group by S1.CompanyID, S1.Price having count(*)<=10 order by S1.CompanyID, S1.Price
I am not sure what is wrong in the first query and why it does not work when the second one works. Could someone help in making the first query work to give me correct results?
