Guys,
Got this query...
---------------------------
SELECT TOP 5 Tbl_admin_hotels.HotelName,
(SELECT COUNT(Tbl_marketing_history.HotelID)
FROM Tbl_marketing_history
WHERE Tbl_marketing_history.HotelID = Tbl_admin_hotels.HotelID)
AS CountTotal,
(SELECT MAX(DateSent)
FROM Tbl_marketing_history
WHERE Tbl_marketing_history.HotelID = Tbl_admin_hotels.HotelID)
AS LastSent
FROM Tbl_admin_hotels
WHERE NOT Tbl_admin_hotels.HotelID = 99
ORDER BY CountTotal DESC
---------------------------
Within the table Tbl_marketing_history there is also a 'Subject' column that
I require, the row to grab this Subject column from should relate to the row
I'm selecting in the SubQuery to grab 'DateSent'.
I've tried and tried to grab multiple columns but failed miserably? Can
anyone help pleaseeee!

Try using a derived table for the aggregates:
SELECT TOP 5
Tbl_admin_hotels.HotelName,
tbl_marketing_history.subject,
countTotal,
lastSent
FROM
Tbl_admin_hotels
JOIN
(SELECT
HotelID,
COUNT(Tbl_marketing_history.HotelID) as countTotal,
MAX( dateSent ) as lastSent
FROM Tbl_marketing_history
GROUP BY HotelID ) as mktHistory
ON mktHistory.HotelID = Tbl_admin_hotels.HotelID
JOIN Tbl_marketing_history
ON Tbl_marketing_history.hotelID = mktHistory.HotelID and
Tbl_marketing_history.dateSent = mktHistory.dateSent
WHERE Tbl_admin_hotels.HotelID != 99
ORDER BY CountTotal DESC

Hi
You may want to try it assumes unique DateSent values for each HotelId :
SELECT TOP 5 A.HotelName,
H.CountTotal,
H.LastSent,
S.Subject
FROM Tbl_admin_hotels A
LEFT JOIN (SELECT HotelId, COUNT(Tbl_marketing_history.HotelID) AS
CountTotal,
MAX(DateSent) AS LastSent
FROM Tbl_marketing_history ) H ON H.HotelID = A.HotelID)
LEFT JOIN Tbl_marketing_history S ON H.HotelID = S.HotelID AND H.LastSent =
S.DateSent
WHERE A.HotelID <> 99
ORDER BY H.CountTotal DESC

Excellent! Had to make a few minor changes but the query worked fine - I
actually understand what you've done (didn't think I would from initially
viewing it!).
So in summary you've created a 'virtual' table that you're then left joining
to the table of HotelID's? Just to confirm my understanding?
One other question, what does the syntax != mean? haven't seen that
previously.
Many thanks for your help!

Thanks for your help John, but I've opted to go for the previous suggestion.
Trouble with the previous suggestion is that I'm getting duplicate entries,
its not selecting distinct hotels??
Presently the resultant recordset has two entries for the same hotel??
Any ideas?

Hi
Posting DDL (Create table Statements etc..) and example data (as insert
statements) always help people to answer your queries. At a guess you have
multiple entries in either the Tbl_admin_hotels
or Tbl_marketing_history.
Try the following to check
SELECT HotelId, COUNT(*)
FROM Tbl_admin_hotels
GROUP BY HotelId
HAVING COUNT(*) > 1
SELECT HotelId, DateSent, COUNT(*)
FROM Tbl_marketing_history
GROUP BY HotelId, DateSent
HAVING COUNT(*) > 1
If there are duplicates then you will need to analyse if the data is valid.
If it isn't then you could correct they data and add unique indexes (or
primary keys if they are missing). If the data is valid then you will need
some method of differentiating them.

Could you have duplicate values for (hotelID, dateSent) in tbl_Marketing_History? I assumed that this was the table's
primary key.
Paul Horan
Sr. Architect VCI

Thanks for your reply Paul,
The tbl_Marketing_History has 'CampaignID' as its primary key, the hotelid
column within that table is merely to relate each mailing to a particular
hotel. There may on occasion be two mailings sent the same date, but rarely.
There's definitely no duplication of a hotel in the Tbl_Admin_Hotels, so I'm
a bit unsure as to why we're getting one hotel twice in the query result?

Hi
If you ran the query I posted i.e.
SELECT HotelId, DateSent, COUNT(*)
FROM Tbl_marketing_history
GROUP BY HotelId, DateSent
HAVING COUNT(*) > 1
You would know for certain if there are duplicates. Without DDL this is made
harder. If DateSent is a SQLServer Datatime data type then there is less
likely to be duplicated, but yours may be a simple character representation.
Your comments tend to imply that your database design is not quite right. I
would expect HotelId and DateSent to be the primary key in a history table
(although Datesent could be an attribute of a mailshot). You do not seem to
have a difference between campaigns and mailshots. I would expect a mailshot
to be attributable to multiple campaigns and vice versa.
With the current SQL you may want to try:
SELECT DISTINCT TOP 5
H.HotelName,
M.subject,
C.countTotal,
C.lastSent
FROM
Tbl_admin_hotels H
JOIN
(SELECT
HotelID,
COUNT(HotelID) as countTotal,
MAX( dateSent ) as lastSent
FROM Tbl_marketing_history
GROUP BY HotelID ) as mktHistory C
ON C.HotelID = H.HotelID
JOIN Tbl_marketing_history M
ON M.hotelID = C.HotelID AND
M.dateSent = C.dateSent
WHERE H.HotelID != 99
ORDER BY CountTotal DESC

Hi John,
Appreciate your help, I'll try to summarise the layout - the
tbl_admin_hotels table stores the unique id and hotel name of each hotel,
the tbl_marketing_history stores each mailing subject, body text and
datelastsent, the only unique column in that table is CampaignID - there is
no duplication unless a mailing is accidently sent twice (impatient people
clicking submit twice ;o))
There's definitely no duplication in the tbl_admin_hotels table - so any
