MSSQL 2008 Query use query result in new query

Hi. i try to figure this out what kind of syntax to use but cant get this to work.
I want. Search in a database after most freqent ID

then make a new query and search in diffrent database whit the result from the first search as a parameter...  please have a look belowe..  I verry new in MSSQL so be nice:D



SELECT DB01.ID, Count(DB01.ID) AS Antal
FROM DB01
where Timestamp BETWEEN '2010-01-13 04:22:53.390' AND '2012-02-13 05:22:53.390'
GROUP BY DB01.ID
HAVING Count(DB01.ID)>1
order by Antal desc

Results  I get..
ID            Antal
09366      936
33593      368
12118      349
11306      303
10424      233
36535      153
38255      131
35700      130

Then I would like to use

the first result "09366"
and search in a nother db.
ex.



Select *
from DB199
where ID=09366
order by Timestamp asc

Select *
from DB199
where ID=(Your first SQL statment here)
order by Timestamp asc
The first SQL stmt must be modified to return the first row . I would do the following on sybase , not sure abt SQLServer

select top 1 COLUMN_NAME from TABLE_NAME order by COLUMN_NAME desc
try

declare @MaxID int

SELECT TOP 1 @MaxID = ID
from
(
	SELECT DB01.ID, Count(DB01.ID) AS Antal
	FROM DB01
	where Timestamp BETWEEN '2010-01-13 04:22:53.390' AND '2012-02-13 05:22:53.390'
	GROUP BY DB01.ID
	HAVING Count(DB01.ID)>1 	
) A
order by A.Antal desc

Select *
from DB199
where ID=@MaxID 
order by Timestamp asc

get some problem

Msg 206, Level 16, State 2, Line 13
Operand type clash: uniqueidentifier is incompatible with int

in the second databse the Id is  declared like a  uniqueidentifier

I can´t change this :(  can I fix this whit your querys?
Try declaring it as uniqueidentifier

declare @MaxID uniqueidentifier

SELECT TOP 1 @MaxID = ID
from
(
	SELECT DB01.ID, Count(DB01.ID) AS Antal
	FROM DB01
	where Timestamp BETWEEN '2010-01-13 04:22:53.390' AND '2012-02-13 05:22:53.390'
	GROUP BY DB01.ID
	HAVING Count(DB01.ID)>1 	
) A
order by A.Antal desc

Select *
from DB199
where ID=@MaxID 
order by Timestamp asc

The problem is in the first DB it´s an int
and in my second database the id is declared like uniqueidentifier

so thaat´s the problem
Can you check the values of ID in your second table. You do understand that they are not integers but GUID
You will not be able to do any meaningful comparison between the two fields. Your second table ID should also have been an integer, or create a new integer field used for joining the two tables.
